Introduction

Carotenoids are pigments found in plants that contribute to photosynthesis and provide various health benefits. Measuring carotenoid content in leaves can help assess plant health, productivity, and the effects of environmental conditions. The determination of carotenoids typically involves extraction followed by spectrophotometric analysis.

Materials and Equipments

• Fresh leaf samples

• Acetone, hexane, or a mixture of acetone and hexane (for extraction)

• Mortar and pestle or homogenizer

• Centrifuge and centrifuge tubes

• Spectrophotometer • Volumetric flasks and pipettes • Analytical balance

Leaf Relative Water Content (RWC) is a key indicator of plant water status and is used to assess water stress, physiological health, and the efficiency of water use in plants. It reflects the amount of water in the leaf relative to its maximum water capacity and is a useful measure in plant physiology and stress studies.

Materials and Equipment

• Fresh leaf samples

• Analytical balance

• Oven or drying equipment

• Desiccator

• Caliper or ruler

• Distilled water

• Petri dishes or similar containers

• Weighing boats or paper

Analytical Reagents

Chemical reagents are supplied in different grades and each grade has a distinct purpose and range of uses. The purest grade is analytical reagent (AR), the second is laboratory reagent (LR), the third is guaranteed reagent (GR) and fourth is technical grade. Second and third form of reagents have a lot of impurities. Therefore, for the determination of micronutrients, AR grade reagents should be used.

Distilled Water

Distilled water is always used in chemical analysis. The quality of distilled water varies from single distilled water to double or triple distilled water depending upon the requirement of analytical technique(s) e.g. double distilled water (glass distilled) is always recommended for micro nutrient and heavy metal analysis.

Buffers

Bronsted and Lowry defined acids as substances which are able to donate protons, and bases as substances which accept protons.

In the above example, BH is an acid because it donates proton and B– is an anion liberated by the deprotonation of the acid. B– behaves like a base, so it is called conjugate base.

Acids can be classified into strong acids and weak acids.

1. Strong acids get dissociated almost completely, e.g., hydrochloric acid, sulphuric acid. This is because the conjugate bases of these acids are very weak (have less affinity for the proton).

2. Weak acids get dissociated partially, e.g., acetic acid, carbonic acid. This happens because the conjugate bases of these acids are strong (have greater affinity for proton). Since the dissociation of the weak acids is partial, the equilibrium constant for the dissociation reaction of the weak acid (BH) can be written as follows:

Volumetric Analysis Precautions

1. Use Clean Glassware: Ensure all glassware, such as burettes, pipettes, and volumetric flasks, is thoroughly cleaned and rinsed with distilled water to avoid contamination and ensure accurate measurements.

2. Clean Glassware Properly: Before use, all glass apparatus should be thoroughly cleaned with a cleansing mixture of potassium dichromate (K2 Cr2 O7 ) and concentrated sulfuric acid (H2 SO4 ) to remove any residual contaminants. After cleaning, rinse the glassware thoroughly with distilled water to ensure no traces of the cleansing mixture remain.

3. Proper Calibration: Calibrate all measuring instruments, including burettes, pipettes, and balances, before use to maintain accuracy in measurements.

4. Avoid Parallax Error: When reading the meniscus level in a burette or volumetric flask, ensure the eye is at the same level as the meniscus to prevent parallax error.

5. Use Correct Indicators: Choose the appropriate indicator for the titration based on the type of reaction and the pH range of the endpoint to ensure precise determination of the endpoint.

The concentration of a true solution refers to the amount of solute present in a given quantity of solvent or solution. It is an important property because it determines the solution’s behavior in chemical reactions, its physical proper ties (such as boiling and freezing points), and its utility in various applications. Concentration can be expressed in several ways, depending on the context and the precision required.

Methods to Express Concentration of a True Solution

1. Molarity (M)

• Definition: Molarity is the number of moles of solute dissolved in one liter (1,000 mL) of solution.

This chapter attempts to travel the timeline and dissect historical perspectives of vaccination. Vaccine that protects and shields from numerous dangerous diseases (vaccine-preventable diseases; VPD) is an important area of research and development. Considering that vaccine has been very useful in successfully combating numerous infectious diseases in the past 200 years, they are considered as a historical turning point in the field of public health and medicines. Critical illnesses like the smallpox and wild polio (virus types 2 and 3) have mostly been eradicated as a result of mass immunisation programmes worldwide. Research, collaboration and widespread vaccination campaigns were necessary in vaccination efforts to control and ultimately eradicate infectious diseases. Biotechnological research has progressed to a level where producing recombinant vaccines is feasible. Research and development efforts on therapeutic vaccines are ongoing. Vaccine research in recombinant DNA/RNA technologies and therapeutic vaccinations for specific illnesses seem to be the future. This article offers a comprehensive history of vaccination since inception to its present forms, with future projections. Beginning with the variolation techniques in the early 17th century, it discusses the important turn of events from its discovery to the continued advancements and inventions till the covid-19 vaccine. Alongside the detailed core aspect, the chapter also describes the benefits of the one health approach with the zoonotic diseases in focus.

The process of vaccine development involves numerous stages from research, discovery, innovation, formulation, testing, mass production, logistics, deployment and administering the vaccine to the target population. The COVID-19 pandemic expedited the endeavour to develop vaccine worldwide that is unparalleled in history. In addition to the steps that were similar during the usual vaccine development process, it called for stronger collaborative teamwork with stricter deadlines during the pandemic due to the emergency situation that built up everywhere (in its spread as well as severity). Research was expedited, potential candidate vaccines were discovered and the proofs of concept were designed that paved the way for pre-clinical efficacy testing. Multiple-step clinical trials to ascertain that the vaccines were effective and safe at least for ‘emergency use’ in human subjects were carried out swiftly. The emergency usage regulatory approval and recommending the usage pattern involved accelerated review procedures. It immediately followed rapid scaling-up for increased production in order to meet the need to save as many human lives as possible across the globe. The approved vaccines were simultaneously evaluated for safety through dedicated pharmacovigilance systems. The future of vaccine development shall also focus on improving the worldwide access to vaccines, managing the virus variants and streamlining mass vaccination campaigns. Comprehending the research, development and administration phases to create and implement life saving vaccinations within the regulatory framework amid international health emergencies as encountered during the COVID-19 pandemic and the enormous collective endeavours are highlighted in this chapter.

Messenger RNA (mRNA) vaccine was the first authorised vaccine developed using mRNA vaccine production technology, against SARS-CoV-2. Well accepted by the population, it proved to be a major life saving intervention during the COVID-19 pandemic. This article discusses the mRNA vaccine technology and its major advantages, and provides an update on the various ongoing and completed clinical trials on the leading mRNA vaccines against various viral diseases. It also delves into the prospects and the technical challenges associated with the manufacturing of mRNA vaccine and the issues with its deployment in the low- and middle-income countries around the world. Despite the already available classical vaccine candidates, the persistent interest and continuous research in mRNA vaccine technology and the related storage, immunogenicity and lipid nanoparticles delivery aspects have helped in expanding and upgrading the vaccinology arsenals to counter diseases. The technology holds promises in opening new vistas to protect against infectious diseases and the associated complications, where safe and effective immunisations are currently lacking. Furthermore, as mRNA vaccines evolve, they offer new hope against neglected and reemerging diseases like rabies, Zika, and Nipah viruses. The flexibility and rapid adaptability of this platform underscore its potential to address unmet medical needs, laying the groundwork for universal and multi-pathogen vaccines, vital in averting future pandemics. Enhanced by advancements in nanotechnology and innovative delivery systems, mRNA vaccines are poised to revolutionise infectious disease prevention, cancer treatment, and genetic disorders, marking a new era in vaccinology and offering hope for global health challenges through continued investment in research and infrastructure.

Constantly emerging and reemerging vaccine-preventable infectious diseases recently around the globe challenged the health infrastructure and has been a critical concern for the medical fraternity. There are 21 other neglected tropical diseases, as classified and recently updated by the World Health Organisation, many of which are seemingly vaccine-preventable. The unprecedented scenario that the world encountered during the recent COVID-19 pandemic was also a ‘silver lining in the dark cloud’ for primarily the vaccinologists. The scientific world witnessed stupendous developments in vaccine development. One such instance was the cutting-edge mRNA vaccine development platform. Once a vaccine is successfully designed, the next step is scaling it up in a milieu that is conducive for its mass production. There are numerous ways to achieve it, from biological system (animal models like the chick embryo, mouse cell-lines, suspension-cultured tobacco cells) to the non-biological (bioreactor) settings. This chapter provides a comprehensive overview of the intricacies in vaccine development, from designing to large-scale manufacturing (mass production). It delves into key scientific guiding principles behind developing and formulating vaccines, adopting both the traditional and emerging bioprocessing and bioseparation engineering and technology. It also explores the technical and management challenges faced before and during scaling up, including maintaining product efficacy, ensuring high quality for human administration, and navigating regulatory landscapes, among others. The chapter offers a holistic understanding of bioprocessing continuum, to educate and inform the research (academia) and development (bioindustry) community for more promising and effective strategies in the future to optimise vaccine production, thus contributing to the global public healthcare initiatives.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that caused the global COVID-19 (coronavirus disease 2019) pandemic has claimed a considerable number of lives worldwide. The unanticipated global spread of SARS CoV-2 has resulted in serious issues within the medical systems and healthcare facilities. Creating efficient vaccines against the virus, even after all of efforts, has been on high priority and is time-taking due to the frequent mutations. A critical stage in vaccine development is figuring out the potential antigen. As a ground breaking technique introduced in 2000, Reverse vaccinology (RV) reduces the required time considerably from 5–15 years to 1–2 years in identifying antigens. Various RV tools are powered by big-data analytics, artificial intelligence (AI) and machine learning (ML) techniques. AI and ML models have demonstrated their potentials in expediting the identification and refinement of novel antivirals or potent vaccination candidates. By utilising datasets available through several dedicated databases, it is more beneficial in identifying current medications that inhibit the human Coronavirus and next-gen healthcare possibilities.

Recent pandemic (COVID-19) impacted global economy significantly and increased economic disparity. Vaccines are significantly beneficial and cost effective compared to other public healthcare preventives. Vaccines reduce hospitalisation, treatment costs and associated morbidity and mortality. Although COVID-19 vaccination and natural viral infection protected against reinfection, it waned in part due to emerging novel variants. Waning immunity from vaccine and natural infection are documented, and it was more so in severe hospitalised COVID-19. Many countries developed their own vaccines successfully to counter as COVID-19 became global. Vaccines needed updates to effectively fight COVID-19 as the wild strain constantly mutated. Among the intrinsic, perinatal, extrinsic, environmental, behavioural and nutritional aspects, the host factors included antibiotics usage pattern, sleep habits, physical activities, smoking habit and alcohol intake. Similarly, the external factors influencing vaccine response included childhood vaccination, early-age infections, nutrient supplements soon after birth, and breastfeeding pattern. Vaccination time also affected the efficacy. Forenoon vaccination developed less breakthrough infection compared to afternoon or evening vaccination due to varying immunological responses like immune cell functions, recruitment and transport, owing to circadian rhythm. Although vaccination side-effects are there, almost all vaccines are reportedly safe, effective and prevented serious illness, hospitalisation and death. Vaccine usually takes two weeks to manifest, and it prevented 14·4–19.8 million pandemic fatalities globally in 185 nations in a single year during December 2020 and December 2021. It was necessary that the boosters alongside vaccines enhanced immunological effects and provided extended protection. Thus, vaccine and booster design and development, dosing, targeted immunisation, cost-efficacy and vaccine acceptance are challenges to address. Government, not-for-profit organisations, health agencies and researchers may systematically analyse, justify and validate vaccine R&D and vaccinations economics. This chapter comprehends biological, commercial and economic benefits and impacts of booster dose in vaccination drives, and the roadmap ahead.

The world turned into a grossly inhabitable during the infamous COVID-19 pandemic, with community health issues everywhere. Each one felt unsafe if other earthly inhabitants were, be it humans or other living beings. Onset of SARS CoV-2 set a ‘new normal’ world order. The ever-evolving and mutating SARS CoV-2 variants extended the pandemic wave after wave thereby complicating the situation, pushing the global healthcare system to its limits and exposing its underbelly. The continually evolving variants were more aggressively transmissive and infective. As the world still reels under tremendous healthcare pressure, other infectious diseases are emerging as are identified by the World Health Organisation (WHO), creating international health emergency situations. The situation becomes alarming with the increasing zoonotic (spillover) and reverse zoonotic (spillback) factors being more proactive in the disease spread. There is a greater need to vaccinate not only humans but also animals, especially the domesticated ones and known reservoirs/carriers. Vaccines must be developed on priority and equitably distributed as the first step to counter a pandemic or potential pandemic. Vaccination is self-limiting due to increasing reported breakthrough infection cases. A strong link of the environmental health to the overall global health needs to be acknowledged, and due diligent measures taken. Hence, there is a strong need of the One Health approach as a 360° solution, and follow it up at global-scale both in letter and spirit. This chapter discusses spillover and spillback of diseases like SARS-CoV-2 and Mpox as case examples, the mitigation strategies and the need for workable One Health models, and challenges and measures to counter future outbreaks. It stresses on foolproof vaccination strategies across to catalyse individual and herd immunities for universal wellbeing.

The pandemic in 2019-2022 spread swiftly and became global in no time, caused by SARS-CoV-2. Vaccines were rapidly developed against the virus to restore public health and save global economy. Vaccines for immunisation drives were developed in a year of the pandemic becoming global and approved for ‘emergency use’ following expeditious development protocols. Vaccine development employed numerous nucleic acid, adenovirus and protein-based state-of-art molecular platforms, alongside the conventional attenuated and inactivated virus approaches. The majority of the attempts were successful and approved for use. All the approved vaccines were found safe and effective as per Phase I through Phase III clinical trials’ results. Mass immunisation drives demonstrably led to reduced hospitalisation, low disease severity and less mortality. Yet, there were initial vaccination hesitation across the world due to associated safety concerns about its possible long-term negative consequences. A part of it was attributed to technical reasons (as clinical trials were not fully complete with sturdy and convincing outcomes), and a majority was due to the misinformation that floated on the social media and other digital communications. Vaccine deployment across the globe was far from being equitable. Thus, immunisation was rapid in higher income (developed) nations with access to innovative advanced vaccines while low immunisation rates were seen in the low- and medium-income countries accessing majorly the vaccines based on simple technology. Given the scale and spread of the pandemic, scaled-up vaccine production and equitable distribution to limit viral spread and improve global health and socioeconomy were critical. This chapter attempts to dissect these scenarios and lessons learnt from these to prepare better for any such pandemic in future.

Traditional agricultural practices have been an integral part of food production in India since ages. These practices have the potential to mitigate the adverse effects of climate change with spatial and sequential diversity (Patel et al., 2020). Traditional Agriculture can be defined as a primitive style of farming that involves the intensive use of indigenous knowledge, traditional tools, natural resources, organic fertilizer and cultural beliefs of the farmers (Abeysekara et al., 2021). It is noteworthy that it is still used by about 50% of the world population. Traditional agriculture can be defined as a set of knowledge- practice-trust nexus which has developed by its adaptive nature and passes on to the next generation through a cultural transmission that explains the relationship between living beings with their environment (Berkes et al., 2000).

Soil is a loose surface material that provides water, nutrients, and structural support to agricultural plants. It is made up of 45% minerals, 5% organic components, 25% air, and 25% water. Our soils are said to be the source of 95% of the food we eat, either directly or indirectly.

The basis of the food chain is healthy soil. Our soils are the foundation of agriculture and the growing media for almost all plants that provide food. Good crops come from good soils, and healthy crops feed people and other animals. Food quantity and quality are, in fact, closely related to soil quality.

A healthy soil is a dynamic, living ecosystem. It is packed with both microscopic and larger organisms that carry out a multitude of essential tasks, such as nutrient cycling—the process of turning dead and decaying matter and minerals into plant nutrients controlling plant diseases and insect and weed pests, enhancing soil structure, which has a positive impact on the soil's ability to hold water and nutrients, and ultimately increasing crop productivity. Because healthy soil retains or increases its carbon content, it also helps to mitigate climate change.

Soil fertility management refers to the practices and techniques used to maintain and improve the fertility of soil. Soil fertility is crucial for agriculture because it determines the soil's ability to provide essential nutrients to plants, support their growth, and sustain productivity over time. Effective soil fertility management aims to optimize soil health and productivity while minimizing environmental impacts.

3.1 Key Aspects of Soil Fertility Management Include

1. Nutrient Management: This involves supplying essential nutrients (nitrogen, phosphorus, potassium, etc.) to the soil through organic or synthetic fertilizers to meet the needs of crops.

2. Soil Amendments: Adding organic matter (such as compost or manure) or other amendments (like lime or gypsum) to improve soil structure, water retention, and nutrient availability.

3. Crop Rotation and Diversification: Rotating crops and diversifying plant species can help manage nutrient depletion and improve soil health by reducing pest and disease pressures.

4. Conservation Tillage: Minimizing soil disturbance through reduced tillage or no-till practices helps preserve soil structure, reduce erosion, and maintain organic matter content.

5. Cover Cropping: Planting cover crops during fallow periods or between main crops helps prevent soil erosion, improve nutrient cycling, and enhance soil fertility.

Seed treatment refers to the application of chemical or biological substances to seeds before planting. This process is designed to protect seeds from diseases, pests, and other adverse conditions that may affect germination and early growth and can improve overall crop yield and quality. Seed treatment can involve the use of fungicides, insecticides, bactericides, and other agents that help improve seed health and vigor. Seed treatment is a crucial step in ensuring healthy crop production. By investing in seed treatment, farmers can achieve better crop establishment and reduce the need for subsequent interventions, leading to more sustainable and cost-effective agricultural practices.

4.1 Importance of Seed Treatment

1. Disease Control: Seed treatment helps to protect seeds and seedlings from soil-borne and seed-borne pathogens, reducing the risk of diseases that can impair seed germination and seedling growth.

2. Pest Protection: Treated seeds are less likely to be damaged by insects and other pests that may be present in the soil. This protection can lead to higher seed survival rates and better crop establishment.

3. Improved Germination: By reducing the incidence of diseases and pests, seed treatment can enhance the germination rate and uniformity of seedlings, leading to more robust and consistent crop stands.

4. Nutrient Provision: Some seed treatments include nutrients or growth promoters that help improve seedling vigor and early development, ensuring that young plants have a better start.

5. Resistance to Environmental Stress: Seed treatments can help seeds withstand adverse environmental conditions such as drought, salinity, and temperature fluctuations, improving the overall resilience of the crop.

IKS stands for Indigenous Knowledge Systems. When applied to pest and disease management in agriculture, IKS refers to the traditional and local knowledge systems developed by communities over generations to deal with agricultural challenges, including pests and diseases.

5.1 Key Aspects of IKS for Pest and Disease Management

1. Traditional Practices: Indigenous communities often have developed practices based on observation and experience to control pests and diseases. These may include specific plant combinations, crop rotations, or timing of planting to minimize pest damage.

2. Natural Remedies: IKS often includes knowledge of natural substances and plants that have pesticidal or medicinal properties. Examples include the use of neem, garlic, chilli, or certain plant extracts to deter pests or control diseases.

3. Cultural Practices: Traditional farming practices may include rituals or timing of activities that are believed to influence pest and disease outbreaks. For instance, planting during specific lunar phases or following certain cultural calendars.

4. Biological Control: Indigenous knowledge may also involve the use of natural enemies of pests, such as predators or parasites, to manage pest populations. This aligns with modern biological control principles.

5. Crop Diversity: Traditional farming systems often promote crop diversity, which can help naturally manage pest and disease pressures by reducing monoculture effects and providing habitats for beneficial organisms.

6.1 Hal for Land Preparation: This plough is constructed from Babool, sal, sisham wood, and mild steel. The body and handle are made from one piece, with a separate shoe. It is operated by one pair of bullocks with a yoke, weighs 48 lbs, and can cover 0.8 to 1 acre per day. It works to an average depth and width of 5 and 6 inches in alluvial soils, with a draught requirement of 185 lbs. It is used by 100% of the farming community in Meerut, Uttar Pradesh. (ICAR, 1960)

6.2 Wetland Plough (Dammu Nagali) for Land Preparation: This plough is made from Babool, palmyra, and mild steel, weighing 30-40 kg. Operated by two bullocks and one man, it is attached to the yoke with ropes for puddling rice fields, covering half an acre per day. It has a draught of 200-220 kg and ploughs to a depth of 4-5 inches and width of 5-6 inches in black and red soils. Repairable locally, its annual maintenance costs range from Rs 0.5 to 1.0, with an operational cost of Rs 25 per hectare. It is widely used in the coastal belt of Andhra Pradesh (Guntur and West Godavari). (ICAR, 1960).

7.1 Method of Drying Cucumber and Pumpkin Seeds: Seeds are combined with wood ash and spread on a plate (Thali) under direct sunlight. This accelerates drying by allowing the wood ash to absorb excess moisture from the seeds, preventing them from clumping together (Mandi, Himachal Pradesh). Verma (1998).

7.2 Drying of Millets, Pulses, and Oilseeds on New Moon Days: Grains are sun-dried to remove moisture. This practice is typically carried out on a 'new moon' day, believed to reduce vulnerability to pest damage (Tamil Nadu). Parvathi et al. (2000). Most of the farmers are storing grain in Amavasya (New moon) because it is believed that risk of pest attack is high in the moonlight as compared to new moon. The leaf of Azadirachta indica (neem) and Calotropis procera (madar) are mixed with cow dung. This mixture used as an excel- lent insecticide and pest growth inhibitor (Joseph et al. 2013; Misra 2014).

7.3 Drying Wheat and Maize Cobs Using Indirect Heat: For drying wheat and maize cobs, indirect heat from the hearth (Chullah) is employed. In traditional houses, typically with three floors, the ground floor shelters domestic animals, the first floor serves as living quarters, and above the kitchen lies a storeroom where freshly harvested maize cobs and wheat are placed for drying. Sunlight also aids in the drying process (Kangra, Himachal Pradesh). Verma (1998).

8.1 Medicinal use of Bamboo in Cattle: The important parts of bans (Bambusa arundinacea) used are the leaf and stem, which contain choline, betain, nuclease, urease, cyanogenetic and glucoside. The leaf acts as an emmenagogue, stimulant, astringent, febrifuge, echbolic, and diuretic. It also acts against leprosy, tympany/bloat, diarrhea, retained placenta, threadworm, cough, and cold in horses. Flowering occurs once in ten to twelve years. The plant dries after flowering. (Parabia et al., 2000).

8.2 Medicinal uses of Dendrocalamus Strictus: The leaf and other parts of kaban (Dendrocalamus strictus), which contain siliceous matter, are used as astringent and ecbolics in animals. (Parabia et al., 2000).

8.3 Medicinal uses of Datura metel, D. alba, D. fastuosa: The leaf, root, fruit, and ripe seed of sadah datura (Datura metel) contain alkaloids such as hyoscyamine, hyoscine, atropine, scopalamine, allantoin, and vitamin C. They are used for treating insanity, fever with catarrh and cerebral complications, and the fruit is used to induce heat in animals and treat prolapse of uterus/ vagina. (Parabia et al., 2000).

8.4 Medicinal uses of Dalbergia Sissoo: The stem bark, root, leaf, and mucilage of sisam (Dalbergia sissoo) contain tannin, dalberginone, dalbergin, allylphenol of latitontype, 5,7,4-trihydroxy-s-methoxyisoflorone, and are used for leprosy, boils, eruptions, to allay vomiting, and the oil is used for cutaneous afflictions. Mucilage of leaves mixed with sweet oil is applied in excoriations. (Parabia et al., 2000).

8.5 Medicinal uses of Cyperus Rotundus: The tubers of motha mutha (Cyperus rotundus) have essential oils, myristic and stearic acid, unstable alkaloid, b-seilinne, cyperenone, and are used as diuretic, emmenagogue, anthelmintic, stimulant, tranquilizer, and antipyretic. (Parabia et al., 2000).

9.1 Plastering Storage area with Lime and Sand: The storage areas, known as Hagevu, are plastered with a mixture of lime and sand. These areas can store 20-30 bags of grain (Heggere and Chitradurga, Karnataka). Nagarathna (2000).

9.2 Indoor Bamboo or Reed Structure for Grain Storage: Indoor storage structures are typically made of bamboo. In regions where bamboo is scarce, farmers use locally available reeds. These structures are cost-effective since they utilize local materials and knowledge, but they do not protect grains from rodents and insects, have a short lifespan, are susceptible to fire, and require frequent maintenance (Andhra Pradesh and Orissa). Navanitha Raju (1999).

9.3 Storage of Onion Bulbs on Bamboo Platform: Onion bulbs can be stored for up to a year on a platform made of loosely woven bamboo strips, raised 2-3 feet above the ground to allow air circulation. The bulbs are piled 2-3 feet high and protected from sun and rain with a cover (Junagadh, Gujarat). Babulbhai (1993).

9.4 Method of Storage of Food Grains in Khanti: A 'Khanti' is constructed in areas with low underground water levels, where a 15-foot deep Khanti can be made. It has a sloping shape with a base 10-15 meters wide and a top one foot wide. A one-foot thick layer of husk mixed with neem is spread at the bottom and sides for pest protection. Different grains can be stored by separating them with layers of husk and large leaves. A Khanti can store 10-15 tonnes of grains from May to November (Maharashtra). Singh (1999).

9.5 Storage of Potato Tubers: Farmers in Hoskote village, Karnataka, store potato tubers in the field on an elevated, hardened soil area of 25 × 4 square feet, supported by 12 stone pillars. A thatched roof provides shade, and a bed of local grass and sugarcane leaves is spread on the floor. Harvested tubers are layered on this bed, with additional layers of leaves on top. The storage is checked for pests every 2-3 weeks. Calotropis gigantea leaves and branches are used around the heap to prevent rodent attacks. This method keeps potatoes cool even in hot conditions (Bangalore, Karnataka). Hannganahalli (1999).

10.1 Multiple transplanting for increasing papaya yield: Papaya seedlings are uprooted and transplanted at a different spot, then uprooted again and planted back at the same spot after fifteen days. This decreases the plant's height and enhances its productive phase (Banaskantha, Gujarat). Kodarbhai (1999).

10.2 Reducing mango flower drop by applying buttermilk and salt: To prevent mango flowers from dropping due to wind and disease, farmers dig a circular trench around the tree trunk during flowering, mix 60-80 liters of buttermilk with 2 kg of salt, and pour it into the trench. After absorption, fresh water is added, and the practice is repeated (Banaskantha, Gujarat). Dudhaji (1997).

10.3 Enhancing fruit set in papaya by inserting a nail in the stem: To induce fruiting in trees that flower but do not bear fruit, farmers insert nails (iron or wooden, 1-2 cm in diameter) into the stem about a foot high (Amreli, Gujarat). Sheldiya (1992).

10.4 Increasing yield of vegetables and fruits by using hair: Waste hair is collected and applied to vegetable, fruit, and ornamental crops. Hair is buried around plants in pits (1/2 kg for ornamental plants, 1 kg for fruit trees) one month after planting and 45 days before fruiting. For vegetables like tomato and brinjal, hair is dispersed during the last ploughing (Tamil Nadu). Subbiah (1998).

10.5 Lemon juice for higher lemon productivity: Farmers increase lemon productivity by spraying a solution of 100 ml lemon juice dissolved in 2 liters of water on lemon trees, ensuring all leaves are wet (Rajkot, Gujarat). Pethan (1997a).

11.1 Control of Diarrhea in Animals Using Traditional Remedies

1. Strychnos potatorum Leaves: In Dahod, Gujarat, approximately 100g of kantas (Strychnos potatorum) leaves are crushed and soaked in water. This mixture is given to the ailing animals for three days (Sitaram, 1997).

2. Ventilago denticulata and Syzygium cumini Mixture: In Bori, Shahera, a mixture of asul (Ventilago denticulata) roots and jamun (Syzygium cumini) bark is crushed and administered with water to the suffering animal. This treatment typically cures diarrhea within 2-3 days. Asul is a creeper found year-round in hedgerows, and jamun is a common tree (Dalsukhbhai, 1993).

3. Decoction of Soymida febrifuga: In Shahera, Gujarat, fresh leaves of royan (Soymida febrifuga) are crushed and soaked in water for one hour. A 100-150 ml dose of this concoction is given to the animal, which usually brings relief within 24 hours. This remedy has a long history in the region (Dalsukhbhai, 1993).

4. Ficus hispida: In Panchmahal, Gujarat, roots of dedhumari (Ficus hispida) are washed, crushed, and soaked in water for one hour. The mixture is then filtered through cloth, and 100-200g of the filtrate is administered to the animal. The treatment typically takes effect within a day and completely cures the animal in about 2-3 days. Many farmers use this method, although they may also consult veterinary experts (Baria, 1993).

5. Umra Bark and Banana Plant: During the monsoon, diarrhea in animals is treated using umra bark and banana (Musa Paradisiaca) plant sap. About 500g of umra bark is pounded and mixed with 500ml of banana stem juice. The mixture is filtered, and the filtrate is given to the affected animal. One hour later, the animal is fed 250ml of groundnut oil, resulting in a cure within a day or two (Valsad, Gujarat) (Patel, 1996).

Black Pepper and Pearl Millet Flour for Disease Control in Chickens: To treat a disease in chickens characterized by frothing at the mouth, frequent cackling, restlessness, and reduced food intake, 10-15 black pepper corns are ground and mixed with pearl millet flour and water to form small pellets. These pellets are fed to the chickens to increase body heat and help eliminate the disease (Sabarkantha, Gujarat) (Parmar, 1992a).

Use of Garlic Against Pulorum in Poultry Birds: To cure chicks affected by Salmonella pulorum, one or two peeled cloves of garlic (Allium sativa) are soaked in a cup of water for 12 hours. The water is then given to the chicks to drink, curing them in two days (Dahod, Gujarat) (Khant, 1999).

Poultry Disease Management: For treating an unidentified disease in poultry birds that kills them within a few days, tribals use various plant-based remedies:

1. Bark of ‘beda’

2. Small pieces of onion

3. Grains of paddy smeared with kerosene

4. Tuber of ‘dev-alad’ (Curcuma spp)

It sounds like you're interested in agro-animal-based yarns, natural dyes, and weaves. These are fascinating topics that blend traditional craftsmanship with sustainable practices. Here are some insights and examples:

1. Agro-animal-based Yarns

a. Wool: Wool is one of the most common agro-animal-based yarns, sourced from sheep. It's known for its warmth, durability, and natural elasticity.

b. Silk: Silk is produced from silkworms, particularly the mulberry silkworm. It's valued for its smooth texture and luxurious appearance.

c. Mohair and Cashmere: These fibers come from goats (Angora and Cashmere goats, respectively). Mohair is known for its luster and durability, while cashmere is prized for its softness and warmth.

2. Natural Dyes

a. Indigo: Derived from the indigo plant, it produces shades of blue and is one of the oldest natural dyes used globally.

1. Forecasting Rain and Frost

i. Behavior of Ants and Goats:

• Ants: When ants come out of their nest carrying their pupae, it indicates that rain will come soon.

• Goats: Goats can sense approaching rain and signal it 2 to 3 days in advance through behavioral changes. They change their usual resting places, show little interest in taking food or water, and bawl and shout throughout the day.

2. Tree Fruiting Patterns:

• Neem Tree (Azadirachta indica): If the neem tree bears plenty of fruit.

• Baval Tree (Acacia nilotica): If the baval tree produces plenty of pods.

• These observations suggest that the total rainfall for the monsoon will be high.

1. Use of banana pseudostem in fish pond to enhance productivity of f ish: Pseudostems of banana, after harvesting the bunch, are added to the pond by cutting longitudinally, which increases the pH and oxygenation of pond water. This practice increases the fish yield. As it involves low cost, it is being followed by 80% of the farmers in Bastar village of Balasore district in Odisha.

2. ITKs on Craft and Gear Making / Maintenance (Vipinkumar et al., 2013): The major ITKs of scientific rationale identified in the craft and gear making and maintenance were ‘Sardine oil smearing on craft wood for improving the durability’, ‘Smearing cashew kernel oil on craft wood for durability’. Similarly, the durability of cotton nets was believed to be improved by dipping in banpu bark decoction. In the same way, beating nets with thalampu plant for ensuring strength was another one identified in craft and gear maintenance. The scientific validity assessment indicated that the boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of oil of sardine. The oil coasts about Rs 70/- per litre. Three cosequitive coatings followed by natural drying under sun are required for good results. Cashew smearing: The boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of cashew nut oil and the oil costs about Rs 40 -50/- per litre. Here also three cosequitive coatings followed by natural drying under sun are required for good results. Smearing Cashew kernel oil on craft wood for durability in Karwar of Karnataka is shown in photograph 1. For improving durability of nets, dipping nets in banpu bark decoction was practiced. The thalambu beating is nowadays not practiced due to the non-availability of those items. Instead, fisherfolk use a powder available in the market especially in the net shops. 1 kg of the colour powder (red/ blue) is required for 1 kg of net. The advantage is that the wastage due to mud coating and dirt can be rectified to a great extent.

1.1. Global Dairy Scenario

Global milk production is forecast at 852 million tonnes in 2019, an increase of 1.4 per cent from 2018 (DAHD, 2019) – a smaller rate of growth, reflecting downward revisions made for India and the European Union. Much of the anticipated output expansion will originate in India, Pakistan, China, the European Union, and Brazil, partially offset by declines in some countries including Australia, Colombia, and Argentina. In India and Pakistan, herd expansions drive output growth, while in China, farm efficiency improvements underpin higher growth. The output is increasing in the European Union, although slowly as dry weather limited the supply of milk during the summer, whilst rising dairy herds and stable milk prices are supporting higher production in Brazil. By contrast, the output may decline in Australia and Colombia due to dry weather, whereas in Argentina, rising feed costs and restrained consumer demand may dampen production. Elsewhere, in the United States, higher milk yields hold up the growth momentum, whereas, in New Zealand, favourable weather corroborates a positive production outlook (DAHD,19).

In India, about 46 per cent of the milk produced is either consumed at the producer level or sold to non-producers in the rural area, the balance 54 per cent of the milk is available for sale to organized and unorganized players. The organized sector comprises of Government, Producers’ Owned Institutions (Milk Cooperatives & Producer Companies), and Private players which provides a fair and transparent system of milk collection round the year at the village level. The unorganized/informal sector involves local milkmen, dudhias, contractors, etc. and they are mostly found to be opportunistic, as there is no uniformity of milk price paid to producers and it varies depending upon the situation. The possibility of adulteration of milk is higher among these unorganized groups. In the areas where competition is high and the presence of the formal sector is strong, the unorganized sector generally gives higher prices and at the same time, the unorganized sector doesn’t offer remunerative prices to the producers where the organized sector is not present.

Cheese, butter, whole milk powder, and skimmed milk powder are a major part of the world’s dairy trade. The demand for worldwide dairy exports is highly concentrated. With a share of 12 per cent, New Zealand is the largest exporter of dairy products, followed by Germany, Netherlands, France and the US. Germany has been the world’s major dairy importer as well with a share of 10 per cent. Other large dairy product importers are China, Netherlands, France, Italy and Belgium.

Before 1999, India was a net importer of dairy products. The successful implementation of the ‘Operation Flood’ program and trade reforms caused the direction of India’s dairy trade to change marginally. India has been a net exporter of dairy products since 2000. Statistics show that India’s export share of dairy products over world dairy exports increased marginally from 0.1 per cent in 2001 to 0.5 per cent in 2019, while its import share of dairy products over world dairy imports increased marginally from 0.018 per cent in 2001 to 0.04 per cent in 2019. The Middle East, South Asia, South East Asia, and the USA are the major markets for India’s dairy products. Conversely, India is a favorable market for the European Union, New Zealand, Australia, UAE, and US dairy products.

In monetary terms, value-added’ per unit of the product is the margin between its selling price and cost of production. However, in the dairy and food industry, value addition refers to, extra, features of a product that are beyond the expectations of a consumer at little or no extra cost. In this context, the addition of value to milk can involve monetary value added to a liter of milk by turning it into milk products, enhancing the convenience of quality, shelf life, or health characteristics using processing and packaging interventions.

4.1. Conversion of Milk into Conventional Products

It is an age-old tradition to add value to milk by processing it into milk products. The primary aim was to increase the shelf life of milk that would otherwise be highly perishable. With inadequate facilities to preserve liquid milk fresh in the rural areas’ conversion of milk into a variety of milk products would be an ideal option to effectively preserve the huge quantities of milk procured during the flush season’ In the processing of milk products such as cream, butter, cheese and ghee, by-products such as skim milk, buttermilk, whey, and ghee residue are obtained’ Many of the dairy plants, particularly in India’ are usually confronted with the problem of by-products utilization, especially that of whey and ghee residue in an economical manner. Membrane separation processes have presented new possibilities for the production of newer intermediate products from dairy by-products that can be used for value addition in dairy and food industries.

Livestock is considered one of the essential variables in the revenue of a farmer. The sector (excluding fisheries) contributes 30 per cent to India’s agriculture gross domestic product, and it is valued at more than Rs. 9 lakh crores. India is also one of the largest producers of milk in the world; around 70 million rural households are engaged in professions linked to dairy. India is also the second largest exporter of bovine meat after Brazil. This sector provides a substantial income to farmers and supports the economy by generating enough demand in the rural and semi-urban regions. This animal husbandry sector comprising dairy and poultry is extremely valuable for farmer’s income security, and Covid-19 has the potential to disrupt this sector.

In developing countries such as India, where dairy farming is one of the most important sources of livelihood for 60 million rural households, 80 per cent of whom are landless, small and marginal farmers who depend on dairy for daily income, the crisis is extreme. Thus, even a small decline in the growth of the dairy sector significantly affects a large chunk of our population which are already vulnerable due to low income, poor savings, and lack of livelihood alternatives. Small production in multiple households leads to more reliance on efficient transportation for procurement. In addition to this, the Indian dairy sector is still dominated by the unorganized sector which handles more than 50 per cent of the marketable surplus. Milkman and vendors collect a small quantity of loose milk from different households and then supply it to urban consumers, roadside eateries, hotels, and sweetshops. Closure of shops and restrictions on transportation has ruthlessly disturbed this arrangement. Even in the formal sector out of the total milk processed 65 to 70 per cent is sold as liquid milk which is immediately vended after packing and only 30 per cent is processed into other dairy products like ghee, butter, cheese, curd, ice-cream, milk powder, etc. Thus, the formal sector also lacks sufficient infrastructure and storage facilities for processing and storing surplus milk after value addition.

The GOI is pushing to strengthen infrastructure for the production of quality milk, as well as for procurement, processing, and marketing of milk and milk products through the following Dairy Development Schemes:

6.1. Dairy Entrepreneurship Development Scheme (DEDS)

Dairy Entrepreneurship Development Scheme (DEDS) was started in September 2010. This scheme is being implemented through NABARD which provides financial assistance to commercially bankable projects with loans from Commercial, Cooperative, Urban and Rural banks.

Objective of the scheme

To generate self-employment and provide infrastructure for the dairy sector, to set up modern dairy farms and infrastructure for the production of clean milk, to encourage heifer calf rearing for conservation and development of good breeding stock, to bring structural changes in the unorganized sector so that initial processing of milk can be taken up at the village level, to upgrade traditional technology to handle milk on a commercial scale, to provide value addition to milk through processing and production of milk products.

7.1. Challenges in Milk Quality

Demand for milk and milk products in India is growing very rapidly, owing to urbanization, customer convenience, and the change from loose to packaged milk products. At present, the dairy sector is rising at about 10-12 per cent annually. Based on population growth projections and an increase in urbanization over the next four decades, India is projected to need approximately 600 million tonnes of milk per year to meet the demand for milk and milk products. This means that India’s milk production needs to grow at around 3.2 per cent CAGR for the next 40 years (FICCI, 2020).

Main reason of poor quantity of milk is due to unhygienic and poor condition of animal farms and dairies. Even due to high demand in foreign country we cannot export such poor quality of milk product. Many times, Indian milk products get rejected in foreign nations due to unhygienic milking milk contains high number of microbial counts. Reasons behind the quality affected in India are due to poor health of animal, polluted water and food and Unclean surrounding in farm. So, it is necessary to consider all this challenges in improving milk production. Currently most of the milking animals are not screened on regular interval of time. So, there is lots of chances that some diseases can transmitted to human beings. Farmers use antibiotics and chemical drugs to increase the production of milk this will also affect the quality of milk. These issues can be avoided by regular screening of animals in animal husbandry and also maintaining history records of health, feed etc. Quality of feed should be checked regularly. There must be pollution control in the feed and water used in cattle farms (Bhagyalaxmi, 2020).

a) A Key GDP Contributor: Dairy and Livestock sector form the backbone of agriculture with 28 per cent contribution in GDP and the progress in this sector is dependent on innovative measures to increase the value for farmers as well as customers.

b) Doubling Farmer’s Income : Doubling Farmer’s Income by 2022 can be achieved by improving crop and livestock productivity, efficiency to utilize resources, increased intensity of cultivation and diversification in high value cash crops, processing and value addition of food and animal products. This price realization can be assured through market reforms and efficient market linkages.

c) Unorganised sector – a challenge : The Indian dairy sector is still characterized by strong presence of unorganized sector. Apart from the Cooperative dairy sector, in the last few years there has been a considerable growth in Private Dairy sector and Milk Producers Organization like Maahi in Gujarat. If small dairy farmers are provided with sufficient ‘value addition’ training and support, they can increase their income considerably.

d) Value addition : Further, the milk processing plants can also go for value addition and innovation and in turn pay remunerative prices to milk producers.

Introduction

Floriculture, the branch of horticulture dedicated to the cultivation of flowers and ornamental plants, has gained significant attention and importance due to its multifaceted prospects and scope. It is a captivating blend of art and science, encompassing the nurturing of plants for aesthetic, commercial and even therapeutic reasons. From the meticulous care of delicate blooms to the strategic planning of vast floral displays, floriculture spans a wide spectrum of activities, each contributing to the beauty and functionality of our surroundings. From the meticulous care of delicate blooms to the strategic planning of vast floral displays, floriculture spans a wide spectrum of activities, each contributing to the beauty and functionality of our surroundings. This can range from the production of cut flowers for floral arrangements and bouquets to the cultivation of potted plants for indoor decoration. Whether it’s the striking colors of roses, the delicate petals of orchids, or the lush foliage of ferns, floriculture celebrates the diversity and splendor of the plant kingdom.

Introduction

Flowers provide opportunity to convert them into exquisite value added products directly from fresh flowers like garland, bouquet, flower arrangements or after drying the flowers making different dried flowers products like pot pourri, wreath, painted gourds or after processing like rose water, gulkand, gulroban, perfume, essential oil, insects repellants, cosmetics etc. Beside this a number of pigments like xanthophylls, carotenoids, luteins, anthocyanins etc. which have neutraceutical properties and pharmaceuticals compounds are also prepared from flowers. The value addition results in more acceptable quality products for the domestic and export market and hence ensure high premium to the producers. Moreover, value addition technology can help avoiding wastage during the glut period and farmers involved in the flower cultivation can earn better remuneration. Preparation of value added products helps in employment generation at producer level, wholesaler level or industrial level. It is a good source of income generation. There are various types of value added products which can be prepared either by practice or by obtaining training of making these products. The value added products can be classified into three categories namely:

In the nursery seedlings, saplings, cuttings and grafts are raised, propagated and multiplied under favorable condition for transplanting in the main field. In nursery, plants are nurtured by providing them with optimum growing condition to ensure germination.

Benefits of Raising Seedlings in Nursery

1. Tender seedlings are looked after very conveniently.

2. Seedlings canbe protected very easliy from pests and diseases.

3. Land can be properly utilised (duration in the main field is reduced).

4. Costly and small size seeds can be raised effeciently without any wastage.

5. Uniformity in the crop can be be maintained by selecting healthy, uniform and vigorous seedlings from the nursery.

Environmental concerns have brought nutrient management in floriculture under increased scrutiny. A goal of sound nutrient management is to maximize the proportion of applied nutrients that is used by the crop (nutrient use efficiency). Soil sampling is a best management practice (BMP) for fertilizer management that will help improve nutrient use efficiency and protect the environment. Soil sampling is also one of the most important steps in a sound crop fertilization program. Poor soil sampling procedures account for more than 90 percent of all errors in fertilizer recommendations based on soil tests. Soil test results are only as good as the soil sample. Once you take a good sample, you must also handle it properly for it to remain a good sample. A good soil testing program can be divided into four Operations: (1) taking the sample, (2) analyzing the sample, (3) interpreting the sample analyses and (4) making the fertilizer recommendations. This chapter focuses on the first step, collecting the soil sample, once you take a sample, you must send it to a laboratory for analysis.

Introduction

Organic farming in floriculture represents a transformative shift towards sustainable and environmentally responsible agricultural practices, responding to the increasing demand for eco-friendly products worldwide. As awareness of the detrimental impacts of chemical pesticides, synthetic fertilizers and monoculture farming grows, consumers and producers alike are increasingly embracing organic methods. This transition is not merely a trend but a necessary evolution towards preserving ecological balance, promoting biodiversity and ensuring the long-term health of both human populations and the planet.The organic farming in floriculture is expansive, encompassing a holistic approach that integrates ecological principles into every aspect of f lower cultivation. Organic floriculture avoids synthetic chemicals, opting instead for natural alternatives that foster healthy soil, robust plant growth and resilient ecosystems. Key practices included in organic farming are crop rotation, green manuring, composting and biological pest control, all of which contribute to maintaining soil fertility and preventing pest outbreaks without harming the environment. These practices help create a self-sustaining system where natural processes regulate plant health, reducing the need for external inputs and enhancing the resilience of the agro-ecosystem.

Introduction

An important concept to remember is that one has to feed plants before the plants can provide us with food. Ornamental plants require the nutrition in proper amount for better growth and yield in open as well as in protected condition. For the cut flower production quality is one of the most important trait and is maintained by the applying the nutrients. Quality is an essential criteria in domestic and export markets. Adequate amount of nutrients in suitable proportions and at right time is the most important factor to improve the plant growth in flower crops. In the present scenario, floriculture is a vast emerging and highly competitive industry. The importance of micronutrient In Indian agriculture the role of micronutrient is well known to all and their use had significantly increased the production and productivity of many crops.

Introduction

Fertilizer efficiency is a critical factor in floriculture, the specialized branch of horticulture focused on the cultivation of flowers and ornamental plants. Floriculture is a highly intensive agricultural practice that requires precise nutrient management to ensure optimal plant growth, vibrant blooms and high yields. The efficiency of fertilizer use in this sector not only influences the quality and quantity of floral products but also has significant implications for economic viability and environmental sustainability.The global floriculture industry is expanding rapidly, driven by increasing consumer demand for f lowers and ornamental plants in both domestic and international markets. This growth necessitates enhanced agricultural practices to meet market needs while maintaining sustainable production systems. Efficient fertilizer use is paramount in this context as it directly affects the productivity, profitability and environmental impact of floriculture operations. Fertilizer efficiency refers to the ability to maximize plant nutrient uptake while minimizing waste and environmental degradation. Achieving this balance is crucial for sustainable f loriculture, as it helps reduce input costs, enhances plant health and mitigates adverse environmental effects such as nutrient runoff and soil degradation.

Introduction

Fungicides are those chemical substances which helps to prevent or kill the growth of fungal spores. Fungicides play a vital role in floriculture, safeguarding ornamental plants from devastating fungal diseases. These diseases, such as leaf spots, blights, root rots and powdery mildew, can significantly diminish the aesthetic and economic value of flowers. Fungicides are indispensable in f loriculture, ensuring the health and beauty of flowers from seedlings to full bloom. They not only protect plants from debilitating diseases but also support the economic viability of flower production. By integrating fungicides with other management practices, floriculturists can achieve a balanced approach that maintains plant health, preserves environmental quality and promotes sustainable production practices. This balanced approach is crucial for the long-term success and sustainability of the floriculture industry. Integrated Pest Management (IPM) practices in floriculture often incorporate fungicides as part of a comprehensive strategy to control fungal diseases. Fungicides, available in various formulations like sprays, dusts and systemic treatments, function by either inhibiting fungal growth or eradicating the fungi entirely. Some fungicides are absorbed by plants, providing extended protection, whereas some fungicides offer immediate, albeit shorter-term relief.

Introduction

Earth worm bring about fertility in the soil was first highlighted by Charles Darwin in 1881 when he published his book on the “Fermentation of vegetables mould through the action of worms. Since then, the vermiculture has become an important aspect of biological or organic farming. Vermicompost aspect involves the use of earthworm as multifaceted bioreactors which effectively recycle the nontoxic organic wastes into the soil. They effeciently utilize the friendly soil microflora, demolish the soil pathogens and converts organic wastes into valueable products such as biofertilizers, biopesticides, vitamins, enzymes, antibiotics, growth hormones and proteinaceous biomass. Earthworms play an important role in soil farming in different ways as:

1) They influences soil pH.2) They act as agents of physical decomposition. 3) They promote humus formation in soil. 4) They improve soil structure 5) They enrich the soil. Vermicompost is the excellent form of organic manure and is practically 100 percent humus.

Introduction

Agriculture sector plays an important role in economy of India and contributes 18% to the GDP. It ensuring food security for more than1.26 billion Indian populations with diminishing cultivable land resource is a herculean task. Pesticides have been the most effective weapons and play vital role in crop protection against agricultural insect-pests. The green revolution technology has been characterized by use of hybrids/ improved varieties, chemical fertilizers, pesticides and irrigation water. After green revolution agricultural production has been very impressive but the excessive use of fertilizers and harmful pesticides has resulted in several undesirable effects on the environment and on the farming systems. However, indiscriminate use of synthetic chemical pesticides over the last four decades has adversely affected human health, non target organisms and environment and has also enhanced development of pesticide resistance among pest species While the former is exemplified by pesticide residues in soil, air, water, food etc., the latter includes phytotoxicity, physiological deform ities, diseases, mortality, population changes, genetic disorders, gene erosion, etc. in plant, mammal, avian, insect and other organisms. Entry of chemical pesticides into food chain and their bioaccumulation triggers several unforeseen consequences. However, in the conventional agriculture most of the weeds, pests, insects and diseases were controlled using natural and sustainable practices such as cultural, mechanical and physical control strategies. Environmental safety and agricultural sustainability are equally important for survival on the Earth. Therefore, it is the need of hour to identify the alternatives of suitable pesticides to control the insects-pests without sacrificing the productivity and profitability. Chemical pesticides has many side effects, eco-friendly management is essentially required for sustainable crop production in the present scenario.

Introduction

Ornamental plants, prized for their aesthetic appeal and vital role in horticulture and landscaping, enhance both private and public spaces with their beauty, contributing significantly to mental well-being and environmental health. These plants, encompassing a diverse array of species and varieties are cultivated not just for their visual splendour but also for their aromatic, structural and ecological benefits. The successful cultivation and maintenance of ornamental plants however require meticulous care and expertise, especially in managing their growth and development. This is where plant growth regulators (PGRs) become indispensable tools in ornamental horticulture Plant growth regulators (PGRs) are a class of naturally occurring and synthetic compounds that play a crucial role in the regulation of plant growth and development. These substances, even when applied in minute concentrations, can have profound effects on various physiological processes within plants, including cell division, elongation, differentiation, flowering, fruiting and senescence. The primary categories of PGRs include auxins, cytokinins, gibberellins, ethylene and abscisic acid, each contributing uniquely to plant development and stress responses. Auxins, such as indole-3-acetic acid (IAA), are pivotal in cell elongation, apical dominance and root initiation, making them indispensable in rooting cuttings and maintaining plant structure. Cytokinins, including kinetin and benzyladenine, promote cell division and shoot formation, thus enhancing branching and delaying leaf senescence.
