Abstract

Indian Horticultural produce to become competitive both in domestic and international markets, there is an urgent need for use of Hi-tech horticultural technologies. The techniques covered under Hi-tech Horticulture are genetically modified horticulture crop varieties derived from biotechnology and genetic engineering, micro-propagation, protected cultivation, micro irrigation and fertigation, high density planting, organic farming, integrated nutrient, pest and disease management and post harvest management.

Micropropagation or tissue culture technology is based on the principle of totipotency. It provides disease free, uniform sized and year round production of mass multiplication of plants in various stages viz. establishment and stablillization, shoot multiplication, pre-transplant and in vitro rooting and transplanting acclimation and ex vitro rooting. Protected cultivation is the technique of providing to the crop to protect plants from the adverse climate conditions by providing optimum growth and development conditions. High value horticulture crops mainly cut flowers and vegetables are more popular for cultivation in green houses. Greenhouse may be of different types depending on the structural designs followed as quonset, curved roof or gable roof and covering materials used as glass, acrylic, polycarbonate, fiberglass reinforced plastic panels or polyethylene etc. applicators. Micro-irrigation system is used for frequent application of required and measured quantity of water directly above or below soil surface, usually as discrete

drops, continuous drops, tiny streams or miniature spray through emitters or applicators placed along a water delivery line (laterals). It may be in form of drip irrigation, bubbler irrigation, micro jet irrigation, sprinkler, micro-sprinkler or misting (fogger) irrigation system. Similarly under fertigation system, special fertilizers in form of liquid or water soluble solids are available through a suitable irrigation system for accuracy of water application.

The history of the pregnancy test is a meaningful history embedded in magic, myth, politics, and science. From ancient Egyptian to modern times, the pregnancy test holds a cultural omnipresence that forces women to confront their fertility, femininity, and their future. Today we know that a pregnancy test that detects the human hormone known as human chorionic gonadatropin (hCG) offers the quickest and most accurate result for determining pregnancy. HCG is secreted by the placenta after the fertilized egg implants in the uterus and can be detected in both urine and blood. Urine pregnancy tests are convenient for home use, but a doctor may also opt to test blood as it provides a quantitative hCG number. Both methods are highly accurate and common. Pregnancy tests, however, were not always so accurate or so culturally accepted.
 
The diagnosis of pregnancy requires a multifaceted approach using three main diagnostic tools. These are (a) history and physical examination, (b)laboratory evaluation, and (c) ultrasonography. Currently, physicians may use all of these tools to diagnose pregnancy at early gestation and to help rule out other pathologies.

Intercropping is growing two or more crops simultaneously on the same piece of land with a definite row pattern. The crops may or may not be sown or harvested at one time.

Advantages of intercropping

Intercropping provides yield advantages as compared to sole cropping. These are not by means of costly input but by the simple expedient of growing crops together.

1.It provides greater surety and stability of higher yield over different seasons.

2.It economizes the space and time of cultivating two or more component crops of comparable agronomic practices grown separately.

3.It helps to restore soil fertility when legumes are included as component crop.

4.It utilizes a greater total volume of both below and above ground environment.

5.It helps to avoid intra-crop competition and thus a higher number of crop plants can be grown per unit area.

6.It helps in better use of growth resources.

7.It also helps in better control of weeds pests and diseases.

8.It also controls erosion through providing continuous leaf cover over the ground surface.

9.It is the small farmers of limited means who is most likely to benefit.

Landscaping is an art of beautifying a piece of land or a landscape with planting material, non-living material in order to create a picturesque effect or to imitate nature. Landscaping makes a place more peaceful, beautiful, appealing or pleasing, where people can rest and enjoy with their family, friends, etc.

Landscape gardening is landscaping of a garden. More or less landscape gardening and painting on a canvas or paper sheet is similar. In both cases colours are used to form a picture, only difference is that painting is non-living 2D image and garden is collection of living plants with non living things in 3D form.

When going for landscaping, one can put anything or collection of different articles of interest in a place. It requires proper planning and for planning landscape, there are principles or facts that should be followed. It is not necessary and also possible to follow all the principles at a time in a landscape plan but there are 8 basic principles one should follow during landscape planning, which are discussed below.

6.1 Introduction

Garden design encompasses the aesthetic beauty, artistry, knowledge of plant growth and development with basic maintenance of plants and other elements as required. Principles are the basic rules of designing a landscape. The basic principles of garden design are very simple; however, each is often referred to by more than one name. Principles of landscape garden keeps the garden lively and beautiful. The principles of gardening should be kept in mind always while designing a garden.

6.2 Axis

It is an imaginary line in landscape designs around which the garden is created striking a balance. In a formal garden the central line is the axis.

Kautilya or Chanakya - probably the world’s first Management Guru who was well known for his management models and strategies - is not the first strategist or author to write the Arthashastra. There were lot of gurus - purva acharyas - and leaders before him. Chanakya studied them all and compiled them into one book known as Kautilya’s Arthashastra. The book was written centuries ago when the country was ruled by kings. But Chanakya had so much wisdom and foresight that, each time you read it, you will discover something new, something different.

The world has changed so much since he wrote the book. We are in the digital age now. But the basic principles haven’t changed. They are eternal. Even almost 2300 years later, we all want the same thing - we want to live a healthy life, a life that has quality. And Chanakya tells you exactly how to do that.

Across the globe, leadership is a subject of serious discussion, study, and research. Universities now have centers of leadership. Many times, in an organization, the members become specialized in their particular field and department but they miss out on the complete picture. The leadership ideas of Chanakya give an insight into some strategic sutras which are simple and easy to understand yet powerful and impactful when applied. Chanakya’s futuristic and time tested sutras relating to Philosophy and Ethics, Thought leadership, Qualities of a leader and Power and Responsibility, etc. will be explored in this chapter.

Homoeopathy is a different system of health care with a holistic, logical and philosophical tailor made approach in the treatment of an individual. The principles of management of diseases or treatment of diseases using homeopathy in animals are in no way different from that of human homeopathy. Homeopathy has potential to cure both human and animal diseases.

Homeopathic Philosophy or Principles

Management of diseases of humans or animals using homeopathy is based on eight basic principles or philosophies.

1. Similia Similibus Curentur- The basic philosophy of homeopathy is based on the ‘Similia Similibus Curentur’ (Latin) or Law of similars (like cures like) , natural law of healing. Which states that a disease can be cured by a drug or substance which is capable of producing similar symptoms in healthy subject when given in minute doses. The treatment in homeopathy is based on the similarity of symptoms of the patient to those of a drug described in Homoeopathic Materia Medica. Drug selection is based not only on the similarity of the presenting symptom, but also on modalities, constitution and temperament of the patient and exciting and fundamental causes.

1. No Tillage (No Ploughing or Turning of the Soil)
• The principle of No Tillage in natural farming refers to the practice of avoiding the mechanical disturbance of the soil, such as ploughing, turning, or tilling. This approach is central to natural farming because it allows the soil to maintain its natural structure, preserves its biodiversity, and enhances its ability to support plant growth sustainably.
• Tillage disrupts the natural layers of the soil. When the soil is left undisturbed, its structure remains intact, allowing for better water infiltration, root penetration, and nutrient availability. A well-structured soil is more resilient to erosion and compaction.
• Soil is home to a vast network of microorganisms, including bacteria, fungi, and earthworms, that play crucial roles in nutrient cycling and plant health. Tilling can destroy these delicate ecosystems, reducing the soil’s fertility. No tillage preserves these beneficial organisms, promoting natural soil regeneration.
• In natural farming, organic matter (like dead plants, mulch, and crop residues) is left on the surface of the soil. As it decomposes, it contributes to the formation of humus, a rich organic material that improves soil fertility and helps retain moisture. Tillage disrupts this process, speeding up the decomposition of organic matter and reducing its long-termbenefits.
• No tillage improves the soil’s ability to absorb and retain water, which reduces the need for irrigation and helps crops withstand drought conditions. Additionally, undisturbed soil is more resistant to erosion because plant roots and soil structure act as a barrier against wind and water erosion.

Farming is the intervention of man in the growth cycle of plants, animals or birds to get utility products of choice at maximum levels and of highest quality. The growing and caring of plants is called Crop Husbandry, and that of animals is called Animal Husbandry. Farming is our most basic activity. It is considered as the backbone of Indian economy. Farming not only nourishes the whole population, but also provides a means of livelihood to more than 60 per cent of our population. Our history, culture and community values are embedded in farming. Today when we think of farming, what comes to our mind are long stretches of farm land, farmer tilling the field, pumping water into fields, applying fertilizers or pesticides, plants with so many fruits, tractors with loads of farm produce, cross bred cows, a farm chicken, aquaculture, fish and so on. A more advanced image on this subject will be of the small plantlets in conical flasks or test tubes, what we call Tissue culture, High Yielding Varieties (HYV), Genetically Modified (GM) crops, Green House farming and other techniques that increase the crop yields. So all these activities are considered as the products of science that our scientists were able to develop over a period of time and helped the growing population to meet their food requirements.

1.1. Plant breeding

An art and science, deals with ways and means to change the genetic architecture of plants so as to attain a particular objective.

For ensuring food security, it is important to breed and develop new varieties that are high-yielding, pests diseases and drought resistant or regionally adapted to different environments and growing conditions.

The techniques used in disease management mainly based on two principles: Prevention or prophylaxis and cure. The first principle prevention includes disease management tactics applied before infection i.e., the plant is protected from disease. It includes: avoidance, exclusion, eradication, resistant & protection. Second principle curative action: functions with any measure applied after the plant is infected i.e., the plant is treated for the disease. It includes therapy.

Introduction
The goal of plant disease management is to reduce the economic and aesthetic damage caused by plant diseases. Conventionally, this has been called plant disease control, but current social and environmental values believe “control” as being absolute and the term too rigid. More multifaceted approaches to disease management, and integrated disease management, have resulted from
this shift in attitude, however. Single often severe measures such as pesticide applications, soil fumigation or burning are no longer in common use. Further, disease management measures are often determined by disease forecasting or disease modeling rather than on either a calendar or prescription basis. Disease management might be viewed as proactive whereas disease control is reactive,
although it is often difficult to distinguish between the two concepts, especially in the application of specific measures.
Plant disease management practices rely on anticipating occurrence of disease and attacking vulnerable points in the disease cycle (i.e., weak links in the infection chain). Therefore, correct diagnosis of a disease is necessary to identify the pathogen, which is the real target of any disease management program. A thorough understanding of the disease cycle, including climatic and other environmental factors that influence the cycle, and cultural requirements of the host plant, are essential to effective management of any disease.

INTRODUCTION

Plant diseases have caused severe losses to humans in several ways. Starvation and uprooting of families resulted from the Irish famine caused by potato late blight . A valued resource was lost with the virtual elimination of the American chestnut by chestnut blight. And direct economic loss such as the estimated one billion dollars lost in one year to American corn growers from southern corn leaf blight . Many plant diseases cause less dramatic losses annually throughout the world but collectively constitute sizable losses to farmers and can reduce the aesthetic values of landscape plants and home gardens.

The goal of plant disease management is to reduce the economic and aesthetic damage caused by plant diseases. Conventionally, this has been called plant disease control, but current social and environmental values believe “control” as being absolute and the term too rigid. More multifaceted approaches to disease management, and integrated disease management, have resulted from this shift in attitude. However, single, often severe, measures, such as pesticide applications, soil fumigation or burning are no longer in common use. Further, disease management measures are often determined by disease forecasting or disease modeling rather than on either a calendar or prescription basis. Disease management might be viewed as proactive whereas disease control is reactive, although it is often difficult to distinguish between the two concepts, especially in the application of specific measures.

Plant disease management practices rely on anticipating occurrence of disease and attacking vulnerable points in the disease cycle (i.e., weak links in the infection chain). Therefore, correct diagnosis of a disease is necessary to identify the pathogen, which is the real target of any disease management program. A thorough understanding of the disease cycle, including climatic and other environmental factors that influence the cycle, and cultural requirements of the host plant, are essential to effective management of any disease.

‘Plant disease management’ involves the integration of various measures adopted to protect the plants by preventing them from contact with the pathogenic organisms, preventing the growth of the pathogens causing diseases, preventing sporulation of the pathogens and spread of diseases, destroying insect vectors responsible for transmitting diseases and such other prophylactic and curative measures. The ultimate aim of these measures is to avoid large-scale occurrence of diseases, reduce the severity of diseases and minimizing the losses caused by diseases. In disease management, importance should be given to control all the diseases attacking a particular crop at a particular time, especially those which occur in severe form in all the seasons and cause extensive damage to the crop and yield loss. Each and every crop is subjected to attack by one or more than one diseases. At the same time the control measures for controlling each of the disease may differ. In this respect a knowledge of the pathogen causing the disease, the symptoms of the disease, mode of infection and spread of the disease, the growth stage at which the crop is attacked, interaction between the host (crop) and the pathogen and weather conditions favorable for the occurrence and spread of the disease is absolutely necessary, so as to adopt suitable control measures to combat the disease and to minimize the damage to the crop, and reduce the yield loss.

The occurrence and spread of diseases are very much influenced by the environment, host and the pathogen. When the environmental conditions are suitable for the pathogen and not quite suitable for the host, the incidence of the disease is liable to be more. Further, if the host plants are not maintained properly and are weak, then they are more vulnerable to attack by the pathogen and the disease incidence may be severe. When the inoculum of the pathogen is present abundantly, the chances of attack by the pathogen are also more. Taking these facts into consideration, plant disease management is depicted as ‘manipulation of the disease triangle’ (Fig. 60)

All control measures should be aimed at protecting the plants from becoming diseased and not at curing the plants after they have become diseased. The principal methods adopted for controlling plant diseases are broadly categorized under five different heads viz. :

Disease Control vs. Disease Management

The word control evokes the notion of finality, the final elimination of problems .

It is impossible to exclude , eliminate or prevent diseases.

Control is ecologically and practically not possible.

Although disease control is an established and widely understood concept, there are compelling reasons to replace control with management .

Basic Concepts of Plant Disease Management
Plant disease management is built upon understanding the Disease Triangle, which consists of three components:
Host: A susceptible plant that can be affected by the pathogen.
Pathogen: A disease-causing agent like fungi, bacteria, or viruses.
Environment: The surrounding conditions, such as temperature, moisture, and wind, that influence disease development.
For a disease to develop, all three components must interact favourably. By manipulating any of these elements, disease outbreaks can be minimized
Principles of Plant Disease Management
Avoidance
Avoidance strategies focus on preventing disease occurrence by altering the environment or planting practices.
a) Site Selection: Select fields with no previous history of specific pathogens. For instance, avoid planting potatoes in fields previously infected with Phytophthora infestans, as the pathogen can survive in the soil and debris.

Horticultural crops are ideal and valuable assets of nature to mankind. They are popular among masses since time immemorial but their importance was realized only in the recent past due to their high nutritive value, good taste and pleasing quality. They provide essential nutrients and minerals for proper functioning of human body and aesthetic surroundings for peaceful living. India is an important centre of diversity and several horticultural crops  originated here.  The horticultural crops constitute 13.08% of total crop area and contribute about 28% to GDP. The sub-continent extends from 8° 04’ - 37° 06’ North latitude and 68° 07’- 97° 25’ East longitude and it has tropical, sub-tropical and temperate climates which favour successful growing of a large number of horticultural crops.  India has a wide variety of climate and soil on which a large number of horticultural crops like fruits, vegetables, potato and other tropical tuber crops, ornamentals, medicinal and aromatic plants, plantation crops, spices, cashew and cocoa are grown. Of late, major emphasis was laid on development of high yielding varieties and high production technologies and their adoption in areas of assured irrigation paved the way towards food security.

India produces 9.2% of world’s vegetables and fruits, nearly 109 million tons of vegetables and 57.69 million tons of fruits. The production of horticultural commodities is expected to grow to 300 million tons in near future (Kaur, 2008). India accounts for 18.2% of global trade in vegetables and 0.5% in fruits. The overall food wastages are very high amounting to around Rs. 10.4 lakh million. India wastes more fruits and vegetables than what U.K consumes. It is estimated that cumulative wastage of fruits and vegetables, on the farm, during procurement, storage and at the retail outlets, is worth about Rs.422250 million. 

The fruits and vegetables are highly perishable in nature. The losses in harvested fruits and vegetables start immediately after harvesting and the resulting spoilage caused by biochemical changes (enzymatic) and activity of microorganisms such as bacteria, moulds and yeast. The losses caused by the microorganism in fruits and vegetables products can be prevented by controlling or destroying these organisms in order to preserve fruits and vegetables by processing and preservation means. The processing and preservation is one of the most important activities among various types of activities of Horticultural Science.

Processing: The processing can be defined as an activity, which is performed to maintain or improve the quality or to change the form or characteristics of the product. Processing operations are undertaken to add value to horticultural produce after their production. The main purpose of processing is to minimize the qualitative and quantitative deterioration of produce after harvest.

Preservation: Preservation can be defined as the science which deals with the methods of prevention of decay or spoilage of produce and allow it to be stored in a fit condition for future use.

Fruits and vegetables can be preserved for short and long term. For short term preservation can be achieved by proper handling of produce and low temperature storage. Long term preservation can be achieved by canning, drying and dehydration, fermentation and by using chemical preservatives.

Public relations (PR) encompass a diverse range of tools and techniques designed to create, maintain, and improve the public image of an organization or individual.

Radiation therapy is the delivery of ionizing radiation to a specific body areas with the goal of obtaining maximum lesion control with minimal complication. Radiation therapy is based on the fact that ionizing radiation is lethal to the cells, particularly rapidly dividing ones. Normal cells in the irradiated area may be as sensitive to ionizing radiation as tumor cells. Therefore, the normal tissue response limits the amount of ionizing radiation that can be tolerated by the patient. Effective use of radiation therapy requires an understanding of the physics of the radiation used and normal cellular and tumor biology as it relates to radiation therapy as well as an appreciation of the clinical application of veterinary radiation therapy.

Radiographic positioning refers to placement of the body in respect to linear alignment of X-ray tube and film. Correct positioning is a most important prerequisite to obtain a diagnostic radiograph. Misinterpretations can result from inaccurate positioning.  Label the film before exposure with anatomical lead markers/ X-rite tape. The anatomical markers should be placed in close proximity to the area of interest without overlying important structures. At least two exposures of the part at 900 to each other should be taken to get complete anatomical information of the part.

Concept: Seed blending is the process of merging two or more types of the same species, for as Kentucky bluegrass cultivars Merion, Baron, and Park. Contrarily, seed mixing refers to the blending of two or more species, however every species may have more than one variation represented, such as Jamestown and Cascade chewing fescue combined with Merion and Fylking Kentucky bluegrass. Seed is typically distributed in blends, primarily Kentucky bluegrass blends, for sod growing purposes. For home lawns, parks, and other utility areas where upkeep levels would not be adequate to maintain pure Kentucky bluegrass turf, mixes of different grasses are typically employed. Naturally, when it comes to pure seed quality, no blend of grass seeds is superior to the individual ingredients. Every time a new blend needs to be made; extreme caution must be taken to ensure that the mixing equipment can be completely cleaned to prevent any contamination from unwanted species—bent grasses are perhaps the most challenging to deal with.

I. FILL UPS

1. _____ is required during raising of a seed crop to avoid contamination due to natural crossing.
2. _____ is another potent source of genetic contamination i.e., the plants differing in their characteristics from the seed variety.
3. Removal of off types is referred as _____.
4. _____ is the distance maintained between the seed crop and source of contaminant.
5. The isolation distance for cotton foundation seed production is _____.
6. The isolation distance for paddy is _____.

1. GENETIC PRINCIPLES

1.1. Maintenance of genetic purity during seed production

The methods suggested by Home (1953) and Hartmann and Kester (1968) may be used wholly or in part to maintain high levels of genetic purity during seed production.

The various steps suggested by Home (1953) to maintain varietal purity are as follows:

6.1. Genetic principles

6.1.1. Maintenance of genetic purity during seed production

1. Steps suggested by Home (1953)

Objective of Seed Storage

The primary goal of seed programs, which include storage, is to maintain the high standards of the seed from harvest until the crop is sown in the following or future seasons. Additionally, seeds are kept in storage for longer periods of time for a variety of reasons, including protection against crop failures during emergencies or natural disasters, maintaining active genetic stocks for breeding, germplasm preservation for long-term use, stock preservation for the domestic and international seed trade in response to market demands, and parental line seed preservation for the transnational seed industry during one or more growing seasons. The seeds of most major agricultural species can be classified as either orthodox or desiccation tolerant. A drop in storage temperature and relative humidity, commonly referred to as seed moisture content, shortens their shelf life. Seeds deteriorate even in dry storage because of alterations caused by pests and pathogens as well as physiological deterioration. This is accurate, even though the amount of time seeds takes to germinate and stay viable varies according to the makeup of the different plant species. A good seed program handles the seed with care, regulates the store’s temperature and relative humidity (or seed moisture in the case of hermetically sealed containers), and adheres to good sanitation practices to preserve the high planting value of the seed in terms of purity, germination, vigour, and seed health.

“Standards are to Industry as Culture is to Society” said Shri C. Rajagopalachari, the first Governor General of India. Shri C. Rajagopalachari was inaugurating a conference on Standardization and Quality Control in February 1948. The great statesman has beautifully summed up the importance of standardization.

The basic principles on which procedures and practices are based had their origin in the United Kingdom, where the first national standardization movement started as early as 1901. Thereafter, procedures have been continuously developed, modified and improved till considerable similarity is achieved.

A systems perspective is essential in understanding sustainability. The system is envisioned in its broadest sense i.e., from the individual farm to the local ecosystem and to communities affected by this farming system both locally and globally. An emphasis on the system allows a longer and thorough view of the consequences of farming practices on both human communities and the environment. A systems approach gives us the tools to explore the interconnections between farming and other aspects of our environment.

Towards Sustainability

Sustainability means preserving human life on Earth. Meeting human needs is thus vital in creating a sustainable society. It follows that one of The Natural Step’s principles of sustainability is to meet human needs worldwide.

2.1 Definition and Key Concepts of Sustainable Aquaculture

Aquaculture, the practice of farming aquatic organisms, has become an essential component of global food production. As the demand for seafood increases, the sustainability of aquaculture practices is critical to ensuring long-term ecological, economic, and social benefits. This essay explores the definition and key concepts of sustainable aquaculture, emphasizing its importance, guiding principles, and the strategies employed to achieve sustainability.

Definition of Sustainable Aquaculture

Sustainable aquaculture refers to the development and management of aquaculture systems that meet the needs of the present without compromising the ability of future generations to meet their own needs. It involves balancing the economic viability, environmental health, and social equity of aquaculture practices. Sustainable aquaculture aims to:

1. Protect and Restore Ecosystems: Minimize environmental impacts and enhance ecosystem services.

2. Support Economic Viability: Ensure the profitability and resilience of aquaculture operations.

3. Promote Social Responsibility: Foster equitable access to resources, benefits, and opportunities for all stakeholders.

Diverse soil and climatic conditions prevailing in different parts of the country offer scope for cultivation of a variety of crops in India.  Around 250 crops either cultivated or grown under natural habitat are used for vegetable purpose.  The crops and varieties vary in their soil and climatic requirements, cultivation practices, resistance to pests and diseases, quality etc.

Considering the climatic conditions for growing vegetable crops and for evolving zone wise technologies and recommendations, the entire country is divided into eight agro-climatic zones under the All India Coordinated  Research Project (Vegetable Crops) as given in Table 1.

Due to continuous pressure on our food security even after independence, the cultivation has been expanded to marginal and sub marginal lands that are prone to different types of erosion. Though the rainfed farming is based on the erratic and uneven rainfall, it contributes nearly 50% food grain, 90% oilseeds and pulses and 65% cotton production.

Glutaraldehyde shall be chosen for the disinfections processes after the disposal of the carcass, subsequent to the post- mortem (however, it is carcinogenic in nature).

Feeding wild animals in captivity presents a fearful challenge. There arehundreds of species to consider, each representing millions of years of evolutionary adaptation to particular ecological system.

Natural foods range from Ants to Antelopes. (Antelope = African (deer like) ruminant, forexample-gazelles, gnus, kudus and impala) and Mouth structures varyfromEdentate (toothless)toCarnassial(specialized pre-molars and molars).

Stomach : These may be

a) Single

b) Quadruple.

Intestines: These may be

a) Tube likeor

b) Equipped with a caecal fermentation vat (vat = large vessel).

On the surface, the problem appears unsolvable, … it certainly is not easy. But the need persists to nourish all captive species as appropriately as possible … it is not feasible to wait until a DATABASE is developed comparable with that which exists for domestic animals.Actually domestic animal data can be very useful for the estimation of nutrient needs of wild counterparts.

Abstract

Inspired by the human eye to brain assessment process, computer vision technology has demonstrated its potential for monitoring and controlling of several operations in food industry. Computer vision technology is, therefore, applied extensively in food drying process for monitoring nutritional value and sensorial characteristics because of its promising characteristics such as reliable objectivity and repeatability. In this chapter, after providing a brief explanation of the computer vision technology and its prerequisites and principles, an example is given to elucidate how this technology is used for monitoring the visual attributes of foodstuffs during drying process. Overall, monitoring the visual properties of food products like size, shape, color, and texture in off-line mode are the most popular issues to fascinate researchers’ attention to apply the computer vision technology in food drying. Nevertheless, industrial applications of the computer vision technology for real-time monitoring and control of food drying facilities as final goals of its introduction in food drying industry seem to be limited. For future studies, it is suggested to apply this unique technology along with advanced soft computing methodologies for in-line monitoring and control of food drying process in order to achieve high quality dried products. Finally, outlooks and potential employment of this technology in food drying domain are discussed as well.

Introduction

Biodynamic farming represents a unique and comprehensive approach to agriculture that integrates scientific and spiritual dimensions to cultivate not just crops, but entire ecosystems. Emerging in the early 20th century as a response to the growing concerns over the industrialization of agriculture, this method is grounded in the principles of anthroposophy, a philosophical movement founded by Rudolf Steiner. Biodynamic farming is not merely a set of agricultural practices; it embodies a worldview that considers the farm as a living, self-sustaining organism, where all elements are interrelated and interdependent.

At its core, biodynamic farming seeks to create a harmonious balance between the physical, biological, and spiritual aspects of farming. It emphasizes the importance of the farm’s natural rhythms, including lunar and cosmic influences, which are believed to impact the growth and health of plants and animals. Farmers who practice biodynamics use a variety of unique preparations made from fermented herbs, minerals, and manure to enhance soil fertility and plant vitality, following a biodynamic calendar that guides the timing of sowing, planting, and harvesting.

It was in 1968 that the term Green Revolution was coined by Dr. William Gaud of USA to describe advances in agriculture arising from productivity improvement. Even in 1968, I concluded that if farm ecology and economics go wrong, nothing else will go right in agriculture.  I expressed my views in the following words in my lecture at the Indian Science Congress Session held at Varanasi in January 1968:

Exploitive agriculture offers great dangers if carried out with only an immediate profit or production motive. The emerging exploitive farming community in India should become aware of this. Intensive cultivation of land without conservation of soil fertility and soil structure would lead, ultimately, to the springing up of deserts. Irrigation without arrangements for drainage would result in soils getting alkaline or saline. Indiscriminate use of pesticides, fungicides and herbicides could cause adverse changes in biological balance as well as lead to an increase in the incidence of cancer and other diseases, through the toxic residues present in the grains or other edible parts. Unscientific tapping of underground water will lead to the rapid exhaustion of this wonderful capital resource left to us through ages of natural farming.

Introduction

The floodplain wetlands or beels are used as multiple use and multiple users system. The large numbers of the stakeholders participate in the beels both within fisheries and across other sectors like forestry, animal husbandry, agriculture, flood control etc. (Sugunan & Sinha 2001, Ramsar Convention Secretariat 2004). The different set of stakeholders constitutes a diverse set of interests, goals and priorities for the fisheries. Therefore, under the present context, the fisheries managers face an extremely complex situation in governing fisheries of the wetlands. Such complexities lead to sub-optimal or unwise use of the wetlands. There is growing concern over the depletion of resources, poor quality of aquatic environment, poor potential realization, poor fisheries management, inequities, conflicts, over exploitation etc of the beels (CIFRI 2000, Pomeroy & William 1994, Welcomme & Bartley 1998). These issues are the outcome of the complex fisheries exploitation system and research efforts are being made to find suitable management regimes to address such issues. The evaluation of outcomes, identification of the shortcomings and understanding decision making process have been an important researchable areas (Pomeroy & William 1994, ICLARM & NSC 1998). Evaluation of a system should include depiction of its goals or objectives and an assessment of how well they are met as well as obstacles faced in meeting them. Accordingly, it is important to identify the management context of the beel fisheries management viz., the formal goals of a fishery management regime; the formal or informal goals of the various actors within it; the processes by which goals are identified and contested; processes through which they are linked to other aspects of the regime- including knowledge production and the implementation of action measures (ICES 2000). Therefore, it is imperative to understand the objectives, decision making process and criteria for evaluation of the fisheries management of the wetlands as a step towards further research in designing effective management regimes. The paper attempts to delineate the system in the simplistic way as well as review the relevant literature to map the objectives, decision making arrangements and evaluation criteria for assessing the fisheries management regimes of the beels. The present paper has been made based on the experience and understanding developed in the context of the beel fisheries management of Assam.

Introduction

The Horticulture crops and commercial crops like sugarcane have become a key drivers for economic development in many of the states in India, and it contributes 29.5 per cent and 24.80 percent respectively to the GDP of agriculture, which calls for technology-led development. The research priorities for genetic resource enhancement and its utilization, enhancing the efficiency of production and reducing the losses in environment friendly manner and effectively channellising the marketing for the produce. Accordingly the research was taken up to study on the prioritization of research for the crops viz., sugarcane, banana and jasmine. The study deals with the knowledge, adoption and research priorities on selected crops’ cultivation which has already been occurred.

The prospects of Farm Animal Genetic Resources (FAnGR) are exceedingly uncertain. The FAnGR characterize the genetic makeup of the thousands of local breeds worldwide which are well-adapted for producing in harsh environments, and which for millennia have been essential in nourishing human communities. Currently, the genetic diversity in numerous livestock breeds across the world is threatened. Decades of consistent selection intended mainly for production increase has caused irreversible loss of genetic diversity (FAO, 2009).

Managing the National Food Security System

Rajiv Gandhi understood the wisdom of Gandhiji’s doctrine that Gram Swaraj is the pathway to Purna Swaraj and launched the Panchayati Raj movement. Schedule 11 of Constitution Amendment 73 entrusts panchayats with the responsibility of managing natural resources and fostering sustainable agriculture. Representative democracy through elected members, one third of whom are women, and participatory democracy through Gram Sabhas, are powerful tools for ensuring a pro-nature, pro-poor, pro-women, and pro-livelihood orientation to all rural and agricultural development programmes.
 
The National Commission on Farmers has emphasised the need for community-managed food and water security systems promoted with the help and oversight of Gram Sabhas.  The Gram Sabha can serve as a Pani Panchayat to ensure that rainwater is not only harvested, but is used in a sustainable and equitable manner.

The objective of the present study was to explore the therapeutic potential of Tribulus terrestris and ITK formulation against obese streptozotocin- induced type II diabetes and diabetic nephropathy in male Wistar rats. In Phase I study, 70% hot ethanolic extract of Tribulus terrestris fruits and hot aqueous extract of ITK formulation (ingredients gum acacia, black cumin, wheat and barley) was prepared and evaluated for in vitro antioxidant and antidiabetic activity of extracts. Extracts have potent antioxidant (studied by 2, 2-Diphenyl 1-picrylhydrazyl (DPPH) and 2, 2’-Azino-bis (3-ethylbenzothiazoline-6 sulphonic acid) (ABTS) radical scavenging assay), antidiabetic (determined by in vitro α-amylase and α-glucosidase inhibitory activity) and glucose uptake potential in cultured lymphocytes and were observed to possess carbohydrates, alkaloids, proteins and amino acids, tannins, flavonoids, saponins, fixed oils and resins in Tribulus terrestris fruits with additional glycosides in ITK formulation after screening by qualitative tests and further confirmed to possess active principles having antidiabetic, antioxidant, nephroprotective, cardioprotective and anti-inflammatory properties.

Pesticide use in agriculture has evolved at several stages in the last few decades. Pesticides, as defined by the FAO, are any substance or mixture of substances intended to prevent, destroy, or control any pest, including vectors of human or animal disease, unwanted species of plants or animals causing harm during or otherwise interfering with the production, processing, storage, transport, or marketing of food, agricultural commodities, wood and wood products, or animal feedstuffs, or substances that may be administered to animals. A plant growth regulator, defoliant, desiccant, or agent used to thin or prevent premature fruit fall, as well as substances applied to crops before or after harvest to prevent them from deteriorating during storage and transportation, are included in this category.

Today’s agrochemistry has a massive challenge: ensuring the availability of high quality active ingredients to enable long-term control of pest species, weeds, and agricultural diseases. The differential uptake and transfer of the active ingredient by target and non-target organisms can contribute to diverse biological activity.

Probability analysis measures the likelihood of uncertain climatic and agricultural events. It is particularly useful for assessing rainfall occurrence, drought, floods, heatwaves, cold events and other risks that cannot be predicted with complete certainty. This chapter introduces classical, empirical, subjective and conditional probability, probability distributions, return periods and recurrence analysis. It explains how historical climatic records can estimate the likelihood and severity of future events. These methods assist in crop selection, sowing decisions, irrigation planning, infrastructure design and weather-risk management. By converting uncertainty into measurable probabilities, the chapter provides a scientific basis for climate-informed agricultural planning, disaster preparedness and development of resilient farming systems.

Abstract

An attempt has been made in this paper to study probability model for modeling of spell distribution & Weather Cycles during the monsoon period (June to September) at Cochbehar, West Bengal. The daily rainfall data of 31 years (1970 to 2000), recorded at Cochbehar have been analyzed. In this study, it was found that daily rainfall during monsoon period follows Markov Chain model. Markov dependent truncated geometric distribution model is best fitted for studying the Dry spells, Wet spells & Weather Cycles during the monsoon period.

True/False

Q.1.    The set of all possible outcomes of a variable along with the frequency (the number of occurrence) of each outcome or a group of outcome is called “Frequency Distribution”.
Q.2.    The frequency of an occurrence of each outcome of a trail divided by total frequency is known as “Relative frequency” of the outcome.
Q.3.    The distribution of total probability “1” into probabilities of occurrence of each outcome of a trial, is known as probability distribution of the outcome.

Random variable: A random variable is a variable that assumes numerical values associated with the events of a random experiment whose outcomes cannot be predicted with certainty. For example, Height of rice plants in a field; seed weight; No. of tillers per rice plant.

A random variable is of two types:-

1. Discrete random variable: The random variable which takes only countable values i.e., integral values. For Example, Number of tillers per rice plant. Here there can be finite no. of values between any two values.
2. Continuous random variables: The random variable which takes values within intervals. These values cannot be counted but can only be measured. Here there can be infinite no. of values between any two values for example, Height of rice plants in field; seed weight.

11.2 Introduction

A probability distribution is a mathematical function that describes the likelihood of obtaining the possible outcomes of a random variable. In other words, it provides the probabilities of different events or values that a random variable can take. The sum of all probabilities in a probability distribution is equal to 1.

A probability distribution is a statistical function that describes all the possible values and likelihoods that a random variable can take within a given range. This range will be restricted between the minimum and maximum possible values.

The probability distribution shows how the set of all possible mutually exclusive events are distributed, and can be presented as an equation, a chart or a table.

A variable which can take different values with given probabilities is called a random variable.

There are numerous probability distributions which may be distinguished by whether the random variable is discrete, taking only a finite set of possible values, or continuous, taking an infinite set of possible values in a range of values.

A discrete random variable with only two possible values is called a binary variable, e.g. pregnant or not pregnant, diseased or healthy.

Probability distributions for discrete random variables The probability distribution for a discrete random variable y is the table, graph or formula that assigns the probability P(y) for each possible value of the variable y.
