Flower is symbol of beauty and by nature attracts every human being. It is a gift of nature to humanity. Flowers symbolize the quintessence of human spirit. In India, losses are estimated to be more than 30-35%. It is due to the lack of knowledge of postharvest management of cut flowers. Several factors at pre harvest stage including genetic or inherent, climatic or environmental and management harvest factors like stage, method, time of harvesting and postharvest factors such as watering, rehydration, precooling, storage environment, packaging techniques and microorganisms influence the postharvest quality and longevity of cut flowers.

Preharvest factors

1. Genetic or inherent makeup: Postharvest lasting quality of flower species and cultivars vary considerably due to differences in their genetic make up. It is therefore desirable to grow cultivars, which possess long vaselife. 

A cropping system refers to the type and sequence of crops grown and practices used for growing them. It is based on the available technologies of crop production. Cropping systems have been traditionally structured to maximize crop yields. Now, there is a strong need to design cropping systems, which take into consideration the emerging social, economic and ecological or environmental concerns for each ecosystem. The goal of a cropping system must be to conserve natural resources i.e. soil, water and sustain crop production. Conserving soil and water and maintaining longterm soil productivity depend largely on the management of cropping systems, which influence the magnitude of soil erosion and soil organic matter dynamics. Crop diversification is an important option in sustainable agricultural systems. Management of cropping systems implies management of tillage, crop residue, nutrients, pests, and practices for soil conservation. Difference between dry land and rainfed farming is as follows.

Orchard management is one of the important aspects in the horticulture industry. Success of orchards is mostly depends upon economic utilization of natural resources namely land, water, trees and other external inputs. All these resources have to be well utilized to the best advantage for higher production per unit area on a sustainable basis without adversely affecting the quality of the environment. Important aspects of orchard management are related with soil and water conservation, canopy management, nutrition management, weed management, plant protection measures, biotic and abiotic stress management, maturity and harvest, post harvest handling, utilization and marketing.

Soil management: Soil management aims at maintaining the fertility and productivity of soil. It creates favorable conditions for moisture supply, proper drainage and nutrient availability. It helps to maintain high fertility level and replenishment against losses, gaseous exchange, microbial activities, it helps to check soil erosion, suppress the weed population, economic utilization of interspace of main crops. Common soil management practices are cultivation, sod culture, mulching and rotation.

The word ‘organic’, means ‘living’, ‘earth friendly’ or ‘of plant or animal origin’. Organic farming is a very native concept of India and has been followed from ancient times. Soil is a living entity and the focus in organic farming is the soil itself. Of course, it is based on understanding the ways of nature. All organic waste from agriculture and other sources is recycled to enrich the soil. Thus, the health of the soil and its structure is maintained. The natural microorganisms of the soil are protected and nurtureed.

Organic farming is primarily aimed at cultivating the land and raising crops in such a way to keep the soil alive and in good health by use of organic wastes and other biological means of sustainable production in an ecofriendly pollution free environment.

As per the definition of the United States Department of Agriculture (USDA) study team; organic farming is a system which avoids or largely excludes the use of synthetic inputs namely fertilizers, pesticides, hormones, feed additives, etc. and to the maximum extent feasible rely upon crop rotations, crop residues, animal manures, off farm organic waste, mineral grade rock additives and biological system of nutrient mobilization and plant protection.

oilless culture is a method of growing plants without soil. It is an artificial means of providing plants with support and a reservoir for nutrients and water. The simplest and oldest method for soilless culture is water culture or solution culture, where inorganic chemicals are dissolved in a vessel containing water to supply all the nutrients to plants. This method was originally termed hydroponics (water working) by W.F. Gericke in the 1930s. Over the years, hydroponics has been used sporadically throughout the world as a commercial means of growing both food and ornamental plants. Today, it is used widely in research facilities as a technique for studying plant nutrition.

Gravel or sand is sometimes used in soilless systems to provide plant support, and retain some nutrients and water. The retention of nutrients and water can be further improved through the use of sphagnum peat, vermiculite, or bark chips. These are the most commonly used materials, but other material such as rice hulls, bagasse (sugarcane refuse), sedge peat, and sawdust are used sometimes as constituents in soilless mixes.

It is difficult to define ‘stress’ precisely. In engineering and the physical sciences, it is usually defined as the force applied per unit area. But as far as in biology, stress it is usually described more loosely as any factor that disturbs normal functioning of an organism. Any environmental factor potentially unfavorable to plant is termed as stress.

The effect of stress on plant condition is called strain. Stress is the action, whereas strain is the reaction. Stress may be defined as external conditions that adversely affect growth, development and productivity. Stress may further classified as:

• Zero stress: This is the level of exposure of plants to environmental factors that leads to neither injury nor reduction in growth and yield of crops.
• Stress escape: Capacity of the plant to complete its life cycle during wet season before onset of stress.

India has an opportunity to grow a variety of horticultural crops due to varied agro climatic conditions and thus, it forms a significant role in total agricultural produce. Though, horticultural crops occupy 8% of the cropped area, approximately 30% contribution in agricultural GDP. Horticultural crops play a unique role in India’s economy by improving the income of the rural people.

However, during the last decades onwards, the productivity of horticultural crops has been affected by many factors. One of the major reasons is climate change. Climate change is one of the most leading environmental problems which is facing the modern world and directly or ultimately to human action that changes the arrangement of the global atmosphere.

The earth climate has always changed in response to changes in the cryosphere, hydrosphere, biosphere and other atmospheric and interacting factors. It is widely accepted that human activities are now increasingly influencing changes in the global cliamte. Emission of increasing amounts of greenhouse gases, carbon dioxide, methane, chlorofluorocarbons and nitrous oxide are responsible for generating changes to global climate. These changes are responsible for rise in sea level, rainfall sequences and movement of climatic regions due to increased temperatures.

Crops that are not part of the customary diet of the local population and grown primarily for their high cash values and export potential are categorized as non- traditional. Non-traditional crops are usually cultivated on low acreage, crops such as ethnic fruits and vegetables, culinary and medicinal herbs, plants for industrial uses etc. are usually considered as non-traditional fruit crops. A non traditional crop may be new to a region or simply new to the grower. Many times non-traditional crops are cultivated to adapt to changing trends in agriculture and demographics.

For growing non-traditional crop proper planning is required to build a comprehensive business case. Realistic assessment of the potential risks and gains is necessary before actual implementation. All aspects of non-traditional crop production, including the agronomics of growing the crop, potential food safety and regulatory issues and marketing needs to be reviewed. Experience of producing conventional crops may not necessarily be directly applicable in producing non-traditional crops.

India has experienced rapid urbanization as well as industrialization since independence. Though, the country has achieved considerable progress in industrial growth as well as expansion of urban and town spread, the land available in urban periphery as well as near big rivers are being utilized for non agriculture purposes. Similarly, for the development of road, rail as well as irrigation infrastructure, the government reserved huge land, which was under cultivation of various crops. The non agricultural businesses became more remunerative near cities and has increased the value of land near cities; which is not affordable for agriculture production. Considering the limitation of land for production purposes in urban areas, the concept of Urban Horticulture was conceived.

1. Introduction

Total population of India is estimated to cross 1.64 billion in 2050. Increasing population, decreasing economic status of Farmer, improper diet and nutrition, fixed farm land, degradation of cultivable land and malnutrition in Indian population is major key problem in 2 to 3 decades. More than 600000 children below 5 year age die due to improper nutrition each year in developing countries (White and Broadley, 1998). All the data provide a scary image about future. Almost 60% of the malnutrition children are iron deficient. Iron deficiency is very common among the girls; 30% each are deficient in zinc and iodine. The incomplete diet and malnutrition can lead to several disorder and degrade the human health (Shuman, 1998).

1. Introduction

Lac and other non-timber forest products (NTFPs) provide vital sustenance, employment, and financial revenue to producers and collectors as well as serving a raw material for a range of businesses. They are also important for ecological balance and long-term growth. Weather and price fluctuations have a significant impact on the production of such natural items. Food, fodder, and medication are all ingested straight from these plants. The Indian subcontinent is a significant centre of animal and plant biodiversity. In tropical climates, a variety of forest products play an important role in social and economic life. Wood and Non-Wood Forest Pro

Introduction

India is often criticized for the negative externalities to the ecology due to the largest livestock population of the country. Thus inspite of the fact that the integrated farming system followed in the country contributes towards not only saving the resources and improving the environment. This study quantifies the positive environmental externalities associated with the livestock production in the context of integrated farming system of rainfed areas. It included land saving due to recycling of agricultural by-products as animal feed and also due to use of dung- cake as domestic fuel, saving of chemical fertilizers due to use of dung as manure and prevention of carbon dioxide emission due to use of animal energy in agriculture.

Biofertilizers are products that contain microorganisms essential for soil fertility and plant growth when added to the soil. Biofertilizers consist of microbes and living bacteria that promote the fertility of the soil and the growth of plants. Biofertilizers are known to play a number of vital roles in soil fertility, crop productivityand production in agriculture as they are eco-friendly and cannot at any cost replacechemical fertilizers that are indispensable for getting maximum crop yields. Increasing useof chemical fertilizers in agriculture make country self-dependent in food production but itdeteriorate environment and cause harmful impacts on living beings. 

Irrigation

Irrigation means the watering of land to make it ready for agriculture. It is the process of application of water to crops through artificial channels to grow them. Water is vital for the growth of plants. And, there can be no plants or crops if they do not have access to water in some form. It is, thus, crucial to supply water to crops and plants in time as per their need. The supply of water to plants comes from various water resources. For example,

• Wells
• Ponds
• Lakes
• Canals
• Dams and Reservoirs

Importance of Irrigation

Irrigation is necessary for agriculture and farming.

Introduction

Mechanized agriculture is the process of using agricultural machinery to mechanize the work of agriculture, greatly increasing farm worker productivity. The effective mechanization contributes to increase production in two major ways: firstly the timeliness of operation and secondly the good quality of work. The requirement of power for certain operations like seedbed preparation, cultivation and harvesting becomes so great that the existing human and animal power in the country appears to be inadequate. As a result, the operations are either partially done or sometimes completely neglected, resulting in low yield due to poor growth or untimely harvesting or both.

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.

Introduction

Nursery is a place where seedlings, cuttings and grafts are raised with care before transplanting.

Advantage of Raising Seedlings in Nursery

1. It is very convenient to look after the tender seedlings
2. It is easy to protect the seedlings from pests and diseases
3. Economy of land usage (duration in the main field is reduced)
4. Valuable and very small seeds can be raised effectively without any wastage
5. Uniform crop stand in the main field can be maintained by selecting healthy, uniform and vigorous seedlings in the nursery itself.

The major mountain ranges in India are the Himalayas and the Western Ghats. The mountain ecosystem is spread over two Union Territories of India: Jammu and Kashmir, Ladakh and eleven states Himachal Pradesh, Uttaranchal, Sikkim, Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Tripura and West Bengal. The hill agriculture has its own unique characteristics and that the growth potential of hill agriculture has remained under-exploited due to various mountain specifities like poor marketing and processing infrastructure, undulating topography, lack of system specific technologies, land degradation, soil erosion, soil acidity and loss of soil fertility. Hill agriculture has several niche areas having comparative advantage for better exploitation of resources and for better trade. Organic farming still remains a viable option for export of specialised commodities especially fruits and vegetables.

• In male animals, endocrine regulation of reproduction is mainly controlled by pituitary gonadotrophins and gonadal androgens. It is not the same as in females as there is only negative feedback controls in case of male while it is positively as well as negatively feedback control in females. In other words, the synchrony of pituitary gonadotrophins with gonads in male is non cyclic while in female it is cyclic i.e. even after castration (absence of androgen) the pulse frequency of LH and FSH is retained. • Sex Hormones are sex specific e.g. estrogen and progesterone work primarily in females and testosterone in males but sex specificity is limited as far as sexual behaviour is concerned. As estrogen injection in castrated ram recovers the maleness while testosterone injection in ovariectomized female maintain the receptivity for male up to a certain extent.

• To identity the normal fertile, infertile (Temporary loss of fertility), subfertile (reduced fertility), or sterile (no fertility) male animals makes the requirement of breeding soundness evaluation necessary. Infertile and sterile animals prove to be harmful for the economic survival of the dairy industry and should be eliminated from the breeding management system. • The breeding soundness examination is very necessary for the breeding management system as the ultimate goal is the achievement of healthy pregnancies. It is also useful for successful artificial insemination (AI) programs that involve the collection and cryo-processing of quality semen.

Semen • Semen, a fluid released from the male reproductive system during ejaculation, is made up of a liquid phase called seminal plasma and a cellular component called spermatozoa. • The term “spermatocrit” refers to the percentage of spermatozoa(v/v) in semen, which varies from less than 2% in pigs to more than 30% in sheep. It is about 10% in bull. Semen= Spermatozoa + seminal plasma Spermatozoon • In 1677, the scientist Van Leeuwenhoek first discovered the spermatozoa and called them ‘‘animalacula’’. • Spermatozoa or sperm cells or male gametes, develop within the wall of the seminiferous tubules as a result of a complex process known as spermatogenesis. • The spermatozoon is a highly specialized cell that performs the sole function of fertilizing an oocyte.

Sperm abnormalities may be genetical or morphological. They are directly related to the male infertility. • The wet mount method and phase contrast microscopy facilitate sperm visualization for abnormalities. Semen stained with vital stain can also be used for evaluating sperm abnormalities. Sperm morphology or related abnormalities can be evaluated by using eosin-nigrosine stain, carbolfuschin, aniline blue-eosine etc. • Generally, for head and tail abnormalities rose Bengal and William’s stain can be used while for acrosome and head abnormalities Giemsa stain can be used. Categorization of Sperm Abnormalities 1. On the basis of site of abnormality on the spermatozoa • Head abnormalities e.g. microcephalic head, macrocephalic/giant head, narrow or short sperm head, pyriform head, detached glea capitis (acrosomal cap), detached head and double head etc

• Semen cryopreservation – It is the process of preserving the semen in a suitable medium at an ultra-low temperature which reduces spermatozoa metabolism with the least production of metabolic waste products of sperm cells to prolong their life span. • Every fall of 100 C temperature decreases the metabolic rate of spermatozoa to half. Principle of various components involved in cryopreservation 1. Low temperature • Reduce metabolism (negligible) and least metabolic waste product • Decrease solute solubility leads to increased viscosity and physical resistance • Reduce motility • Prolong life span 2. Protection from cold shock and cryoinjury • When sperm cells are subjected to a reduction in temperature during the freezing process, there are: • Sperm membrane damages and lead to leakage of intracellular components like enzymes, ATP, K+ , cholesterol, lipoproteins etc. • Irreversible abnormality in motility pattern (bending of sperm tail)

Introduction Kale (Brassica oleracea var. acephala) belongs to family Cruciferae or Brassicaceae is a under exploited vegetable crop. It is introduced in 19th century. Economic Importance and Uses Its edible part is leaves and contains amazing source of amino acids, vitamins and minerals which has many medical advantages. It helps in lowering of blood cholesterol level which helps in lessening the heart illness. Kale leaves is also rich source of beta carotene, ascorbic acid and phylloquinone. Kale is a nutritious vegetable that is rich in vitamins A, C, and K, as well as calcium and iron. It is also a good source of antioxidants and fiber, making it a popular choice for health-conscious consumers. Kale is not so popular crop in India therefore it confined to very few states of Northern India like HP, UP, J & K, Pb and Haryana.

Hilly areas of India, especially the Himalayas and the Nilgiris which are rich in their forests areas and watersheds have played a major role in maintaining climatic and ecological balance in the country for a long time. These hills and mountain areas have specific characteristics which differs them from plains in diversity of habitats for flora and fauna, ethnic diversity, topography, elevation, physiographic feature land use systems and socio-economic conditions. Agro-biodiversity The hills are characterized by rich agrobiodiversity. These rich agro-diversity elements have evolved, over the years due to association with the communities distributed along the mountain and hill slopes.

Besides diversities and advantages in hills, the communities sustain largely on subsistence farming due to following constraints A.Natural constraints in hills There are large number of Inherent limitations in hill agriculture like, remote areas, vulnerability, marginality , eroded soil and short growing seasons. These Inherent constraints can be judged by the use of unsustainability indicators of hill agriculture which further showed increased in soil erosion rates from sloping farmlands , leaving of agricultural land due to decreasing soil fertility, appearance of stones and rocks on the cultivated lands, reduction in forest and grazing areas and more emphasis on monocropping that widened the cycle of inadequate food production and lead to food insecurity and increasing unemployment and frustration (Table 3) (Shrestha, 1992). These natural constraints are.

. Introduction Millets, once considered as humble and forgotten grains, have made a remarkable comeback owing to their numerous health benefits, sustainability, and resilience in diverse agroclimatic conditions. Millet consumption is gaining momentum globally and thus it becomes imperative to establish clear and comprehensive standards for these grains. The chapter gives an insight into the reasons why millet standards are necessary, the challenges associated with implementing such standards and advocacy for a concerted effort to promote these nutritious grains as staples in our diets.

Intoduction Cybertaxonomy is an abbreviation for "cyber-enabled taxonomy." It shares the traditional goals of taxonomy: to explore, discover, characterize, name, and classify species; to study their phylogenetic relationships; and to map their ecological associations and geographic distributions. To improve the speed with which we can help in providing taxonomic products and information, there is undoubtedly a requirement to move taxonomic endeavour into the digital era. Currently, the rate at which we record and maintain morphological information that enables species discovery is the primary constraint on taxonomic productivity (Lasalle, et al., 2009). Cybertaxonomy is one attempt to accomplish this complex goal. Cybertaxonomy employs a collection of electronic tools to assist and equip the science of taxonomy in accelerating species invention and the implementation of taxonomic expertise in biodiversity investigation.Cybertaxomy can yield results more quickly and efficiently than ever before thanks to adoption of digital technologies and cybertaxonomy.

Sample Preparation

 Cheese sample is prepared by passing through 8 mesh sieve three times or

grate sample and mix thoroughly or grind to a uniform mass in a glass pestle

and mortar. Keep the sample in an airtight container until the time of analysis.

 1 Determination of Moisture Content in Cheese

 Introduction

The moisture content of cheese is defined as the loss in mass, expressed as a

percentage by mass when the product is heated in a hot air oven at 102 ± 2°C

to constant mass.

A) Hypothyroidism

Etiology

It is one of the common endocrine disorders of skin of dogs mainly due to deficiency of thyroid hormone followed by cutaneous and non cutaneous signs. It is caused by lymphocytic thyroiditis or idiopathic thyroid necrosis and atrophy. Deficiency of thyroid hormone hinders the metabolic processes throughout the body.

The mast cell tumors are focal or multicentric in nature in the skin and occasionally in the internal organs. It is more common in middle aged dogs without sex predilection.

Site of incision- Make a mid-lateral and mid-medial longitudinal incision on forelimb from elbow joint to 3rd digit. Join the above incisions transversally on caudal aspect at elbow joint above and 3rd phalanx below, respectively. Remove the skin on palmero-medial aspect of limb.

Site of incision

Remove the skin of intermandibular space.Then remove one of the rami of mandible by disarticulating temporo-mandibular joint at caudal end and cut the ramus just behind the mental foramen.

Site of incision: Make a dorsoventral incision along caudal border of last rib up to mid ventral region of abdomen and another incision along the coxal tuber up to mid ventral region of abdomen. Joins the above two incision mid ventrally and reflect the skin up to mid dorsal aspect of lumber region.

From both ends of this incision make vertical incision up to medial aspect of stifle joint and joins distal end of these vertical incision together and remove the skin to expose the muscles of medial aspect of thigh region. To expose deeper muscles incise the vertebral attachment of biceps femoris, reflect it caudally by incising muscle close to stifle than reflect middle gluteus muscle dorsocranially and observe the deeper layer of muscles.

Site of incision: Make two incisions at mid-lateral aspect at base of the tail join them dorso-ventrally and reflect the skin caudally up the 4-5 inches.

Introduction

Agriculture as a primary sector in India is mostly production oriented. Global agriculture is experiencing significant changes in terms of technological and digital revolution, rapid urbanization, faster growth in middle income groups, changing food habits, market oscillations, and above all, climate change. During the last 50 years, India has recorded 4 to 10-fold increase in agriculture and food production(food grains-290 MT, horticultural produce -315 MT, milk production nearly 180 MT, and fish production approaching 12 MT), rendering the country as the second largest agrarian economy in the world (Singh, 2019). Despite the excellent progress, the country is home to over one third of the world’s small and marginal farm holders, with scattered land holding. Eighty f ive percent of the farmers are small and marginal. On the other hand, world’s population is growing and to meet the growing food demand there is a need to increase agricultural output by at least 60 percent globally, and 100 percent in developing countries (FAO, 2014a)

Introduction

Agriculture sector is currently at the crossroads, which is evident in terms of higher nutritive food requirements juxtaposed with growing population. Food production faces multiple challenges due to frequent occurrence of natural calamities, sudden rise in temperature, increase in occurrence of disease and pests leading to both pre and postharvest crop loss. Alarming decrease in fertility status of high and medium land soils of Odisha due to formation of hard clay pan below 4-6” of soil depth has resulted in slowing down of nutrient mineralization by the soil microorganisms within the soil. Crop production stress is further aggravated due to steady decrease in availability of cultivable land with the advent of urbanization, which concurrently reduced the number of dedicated agricultural households. It has been estimated that production of all food grains and horticultural crops needs to be doubled at farmer’s level in order to feed the growing population of the world failing which there will be food crisis by2050.

The term ‘gender’ was first used by Ann Oakley and others in 1970s to describe the characteristics of men and women which are socially determined in contrast to biological differences. The term ‘gender’ further explains, a neutral term meaning, either men or women or both are in a particular context. The goal is to improve the status of disadvantaged class and get rid of socially created and approved discriminations. The green revolution in India changed the face of agriculture but apparently it contributed to two general trends (FAO, 1996) where wealthy have benefited more from technological change in agriculture than the less well off and secondly men have benefited more than women. In general, it is true that the priorities are set by men and some women, who are unaware of gender issues, and that these are seldom considered unless the research is sociological. But even social research can be totally gender blind.

Introduction

For capacity building of farming community, training plays a vital role. It helps in enriching the knowledge along with enhancement of essential skill required in performing certain practices in a specific crop cultivation. The skills required by a coconut cultivator need to be supplemented with additional skills in order to increase the yield of nuts. Government provide better support to the coconut growing farmers to improve their income, to reduce the risk involved in cultivation, implementation of quality agricultural practices and f inally enhancing the income of coconut grower in business mode. Training is a source of information, advice and influence in the decision making process. Training helps in enhancement of knowledge, improvement of skill, interaction with experts and to build confidence. Keeping this in view, the present study was conducted to know the training need areas of coconut growers in Gop block of Puri district of the state of Odisha.

Introduction

Agriculture is an important sector in Indian economy, 58 per cent of India’s population depends on agriculture for their livelihood. Agriculture is main victim of climate change, it can disrupt availability, accessibility and quality of food. Moreover, increase in temperature, reduction in ground water availability, f looding and salinity are the major limiting factors in sustaining and increasing vegetable productivity. As a result of this crop physiology and production both are affected. Organic farming can help to tackle climate change by reducing greenhouse gas emissions and amount of nitrogen fertilizer applied to farming land. In India we have advantage that the agricultural techniques we practiced before green revolution in our country is eco-friendly and today also it is somehow it is in memories of our older and younger farmer generation. Principle of sustainable farming is the base of organic farming. According to OECD (Organization for Economic Cooperation and Development) “Sustainable agro-ecosystem - agricultural and food systems are economically viable, meet society’s need for food assurance, while they retain and enhance natural resources and environmental quality for future generations” it is very clear from the definition that organic farming mostly emphasizes the environmental aspect and it includes.

Introduction

Agriculture is the measure livelihood of tribals in India. Indigenous Tuber crops, like Elephant foot yam (Amorphophallus) and Dioscorea play a valuable role to uplift the socio and economic status of people of tribal areas (tribal farmers) in terms of nutritional security and livelihood. In every year rural India subjected to wide spread of poverty, malnutrition, infant mortality rate etc. Ecological degradation, climate change, erratic rainfall and drought are the principal causes of food insecurity in these tribal areas resulting migration, periodic starvation and deaths. Therefore under erratic climate, tuber crops like Amorphophallus and Dioscorea, played a crucial role as life support crops to combat hidden hunger. Tuber crops are the traditional crops cultivated in order to meet the food requirements and give economical sustainability to the people. After cereals and legumes, tuber crops constitute a major staple or subsidiary food for all. Amorphophallus paeoniifolious and Dioscorea alata, important tropical tuber crops are excellent dietary staple for low-income consumers in tribal areas of Odisha state, better opting tuber crops cultivation rather than forest produces.

Introduction

Cotton is a fiber crop of Malvaceous family. There are four cultivated species of cotton viz. Gossypium arboreum, G. herbaceum, G. hirsutum and G. barbadense out of which G. hirsutum is the predominant species contributing about 90% to the global production. In India all the above four cultivated species are grown on commercial scale as a kharif crop. India is the largest producer as well as consumer of cotton in the world. The major cotton growing states of India are Maharashtra, Punjab, Haryana, Rajasthan, Uttar Pradesh, Madhya Pradesh, Gujarat and parts of Andhra Pradesh & Karnataka. In Odisha cotton cultivation is an up-coming activity. Many of the western belt farmers, mainly from Rayagada, Bolangir, Kalahandi, Nabarangpur, and Nuapara districts have been taking cultivation of this cash crop. According to the report of Odisha economic survey, 2018-19 a total of 1.45 lakh ha area was cultivated in 2017-18 producing 3.65lakh bales of cotton. In Rayagada district cotton is cultivated in 9 blocks out of 11 blocks comprising an area of 35170 ha. For the year 2018-19 yield was 12.37 q/ha with production of 25.6 MT of cotton according to the data given by District agriculture office, Rayagada.

Agricultural production system has gone a long way in supporting the world’s food requirement. The projected estimates revealed that to meet the global population of about 11.3 billion in 2050, the global demand for cereal will increase by 60% (Rosegrant and Cline, 2003, Bengtsson et al., 2006). Agriculture is considered as the chief agent of environmental transformation. The unrestrained attitude of Homo sapiens towards the use of natural resource catalyzing the causes leading to global warming, has increased the challenges manifold to provide food security in a sustainable manner. Increased concentration of CO2 and other green house gases have resulted in an increase of 0.760 C in surface temperature globally since nineteenth century and the mean global surface temperature is predicted to increase by an additional 1.30C to 1.80C by 2050( IPCC, 2007). Sinha and Swaminathan (1991) reported that an increase of 20C in temperature could decrease the rice yield by about 0.75 t/ha in the high yield areas and a 0.5oC increase in winter temperature would reduce wheat yield 0.45 t/ha.

Startup India, the initiative of Government of India, was first announced by Honourable Prime Minister Mr Narendra Modi during his Independence Day speech on 15 August, 2015 and discussed elaborately again on 27 December 2015 in his radio address ‘Maan ki baat’ mentioning startup as new opportunities for the youth who want to set up new business or innovative projects. Indian Government lunched this ‘Startup India – Standup India’ campaign on 16 January 2016 with an intention to build a strong startup ecosystem for nurturing innovation and encouraging private investment.
