9.1 INTRODUCTION

India is the second largest producer of fruit crops with annual production of 68.4 million metric tonnes from an area of 6.1million ha (Anon 2010). The national horticulture mission commenced in 2005 had fixed a target to double the horticultural production by 2011-12. According to the available production data of horticultural crops, it seems that we are very close to achieve our target. But, if the loss caused by biotic and abiotic stresses is accounted, a sound conclusion can be drawn that still there is a huge scope for productivity improvement in fruit crops.

Among biotic factors bacteria, fungi, nematodes, viruses and insect pests, diseases and other pests are widely recognized as the biggest threat to the sustainable production of fruit crops. Every fruit crop is infected with one or other pathogen/pest, which causes a significant reduction in yield. The disease alone both in field and storage accounts for 25-30 per cent losses (Rangaswami and Mahadevan 2002). Along with diseases, insect-pests also cause reduction in the yield. About 600 insect and mite pests have been reported in temperate fruits alone in India (Sharma and Singh 2006).

Beside biotic factors, abiotic factors (salt, drought, low and high temperature) also limit the potential yield of fruit crops. It is estimated that nearly 10 million ha is affected by salinity/alkalinity in India (Singh 2006). Moreover, fruit cultivars are also to be modified for yield and traits of consumers preference e.g. seedlessness in grapes and citrus.

Genetic improvement can be achieved by following the conventional breeding approaches, when the gene of interest is present in related cultivars/species and the crop is sexually crossable. But due to long juvenility and genetically prevalent problems like incompatibility, sterility in most of the fruit crops and apomixis in citrus, mango and apple, conventional techniques seem to have limited role in the improvement of fruit crops.

Various biotechnological approaches either alone or in combination with conventional breeding approaches can provide a direct solution for the genetic improvement of fruit crops.

10.1 INTRODUCTION

Agriculture is a very important sector for the sustained growth of the Indian economy. About 70 per cent of the rural households and 8 per cent of urban households are still dependent on agriculture for their livelihood. Though, industrialization of the Indian economy has adversely affected the share of agriculture in the GDP, the fact can not be ignored that India has undergone a series of successful agricultural revolutions-starting with the ‘green’ revolution in wheat and rice in the 1960’s and 1970’s, the ‘white’ revolution in milk to the ‘yellow’ revolution in oilseeds in 1980’s. As a result, India has achieved self-sufficiency in agriculture. Applications of agricultural inputs at uniform rates across the field without due regard to in-field variations in soil fertility and crop conditions does not yield desirable results in terms of crop yield. The management of in-field variability in soil fertility and crop conditions for improving the crop production and minimizing the environmental impact is the crux of precision farming. Geographically, India is widely distributed into several agro-climatic zones, and the information needs for the farming systems in these areas are entirely different. Integrating the application of available technologies to realize farmers’ goals requires a systems approach to farming.

11.1 INTRODUCTION

Citrus as a perennial crop occupies globally a place of prime importance amongst major fruit crops including India. The cultivation of citrus in India is dominated by three major cultivars viz., mandarin, sweet orange, limes and lemons occupying collectively an area of 9.23 lakh ha with a production of 86.08 lakh tonnes and productivity of 9.3 tonnes/ha. Nagpur mandarin in India is grown in 0.97 lakh ha area with total production of 8.81 lakh tonnes and productivity of 9.l tonnes/ha, respectively. The productivity of mandarins within the country is highly variable in space and time, the major constraint is inadequate and unbalanced fertilizer use. The commercial cultivation of Nagpur mandarin is extensively confined along the Satpuda foothills of central India comprising Chindwara region of Madhya Pradesh and Vidarbha region of Maharashtra. The nutrient demand is highly variable in space (due to heterogenous soils) and time (due to varying weather conditions). Therefore, determination of crop nutrient requirement is a subject of great complexity. Experiments have shown that soils initially rich in fertility developed a variety of nutrient constraints following the non-synchronisation in demand and supply of nutrients with the orchard age (Srivastava et al., 1998). For example when exchangeable K is not rapidly replenished, crops start drawing on the non-exchangeable K, resulting in soil mining and depletion in soil K reserve. A nutrient level sufficient for one particular productivity level may not hold sufficient for other higher productivity levels. An extensive survey of 18,000 ha area of Nagpur mandarin orchards of central India showed large scale deficiency of three nutrients viz., N, P and Zn, with most of the sites expressing multiple nutrient deficiencies (Srivastava and Singh 2002; 2005). Reduced longevity of commercial citrus orchards due to varying nutritional constraints is one of the major production related constraints highly responsible for poor orchard efficiency (Srivastava and Singh, 2008a; 2008b).

12.1 INTRODUCTION

Oil Palm (Elaeis guineensis Jacq.) is a heavy feeder and needs a balanced and adequate supply of nutrients for growth and yield. Fertilizer is one of the most costly inputs, which accounts for greater part of production costs in the cultivation of oil palm. Large amount of nutrients are removed by the fruit bunches harvested from the mature palms. It is estimated that 25 tonnes fresh fruit bunches per hectare per year removes 93.5 Kg Nitrogen, 11.0 Kg Phosphorous, 92.7 Kg Potassium, 19.3 Kg Magnesium and 20.3 Kg Calcium.

Economic yields of oil palm are achieved when the supply of nutrients from the soil, palm residues and fertilizers are properly integrated in required quantities. Leaf analysis is an analytical tool for detecting the nutrient requirements in oil palm and other perennial crops, which are slow growing and can provide easily, defined standard leaf material for analysis due to leaf phyllotaxis. Nutrient deficiency symptoms are also an important means for determining the nutritional problems in oil palm, since the crop presents easily identifiable N, K and Mg deficiency symptoms. However, by the time symptoms are evident, nutrient deficiency might have already affected growth and yield.

Also the nutrient supply may be insufficient before the appearance of leaf symptoms. So there is a need for a thorough inspection of the leaf canopy to corroborate the results of leaf analysis and identify the areas with severe nutrient deficiencies. The research on oil palm nutrition was carried out under rainfed conditions at Palode, Kerala and irrigated conditions at Pedavegi, Andhra Pradesh.

In India, a great variety of soils ranging from red sandy loams/sandy clay loams (Alfisols), alluvial silt loams (Inceptisols / Entisols), heavy black soils (Vertisols) and acidic red laterite soils (Oxisols) are put to oil palm cultivation. In Andhra Pradesh, it is grown in red sandy, red loamy, red loam with clay base, deltaic alluvium pH - 6.5 to 9.0. In Karnataka, it is grown in red and brown sandy loams and black clayey soils, with pH - 6.5 to 9.0. Red soils, red loamy soils and clay loam soils are used for growing oil palm in Tamil Nadu. Laterite soils are used for oil palm cultivation in Kerala.

13.1 INTRODUCTION

The hot arid regions are spread over about 31.7 million ha area mainly in the States of Rajasthan, Gujarat, Andhra Pradesh, Punjab and Haryana, which inhabit on an average 61 persons per square km making up a home for population of nearly 20 million people. The Indian arid zone is characterized by high temperature and low and variable precipitation which limit the scope for high horticultural productivity. However, these conditions greatly favour development of high quality production of fruits such as date palm, ber, pomegranate, citrus, aonla, bael, grapes, guava and vegetables such as cucurbitaceous crops, spices and some medicinal plants. The optimized technologies and inputs could increase the existing low productivity. It is now realized that there is a limited scope for quantum jump in fruit and vegetable production in the traditional production areas. The amelioration of the extreme conditions is also considered vital for life support to the inhabitants of this area. The recent awareness regarding the potential of these ecologically fragile lands for production of quality horticultural produce has not only opened up scope for providing economic sustenance for the people of this region, but also for bringing new areas to increase production through horticulture.

The arid horticultural crops have developed and/or modified to perform certain vital physiological functions even under stress. Strong deep root system (ber, bael, aonla, wood apple, jamun, etc.), moisture synchronous flowering and fruit development (ker, lasora, aonla, pilu, etc.) and other xerophytic characters i.e. leaf shedding in summer (ber), scanty foliage (ker), spiny cladode (cactus pear), mucilaginous sap in plant part (ker, gonda, pilu, bael, etc.), sunken stomata and fur/ hairiness and waxy coating on the leaf surface (phalsa, ber, gonda, fig, etc.) thorny nature, and selective or reduced absorption of cation (Na⁺) and anions (Cl^-, SO4^—) for survival under adverse arid conditions are peculiar adaptations. Therefore, cultivation of suitable species of fruit and vegetables in the arid areas will increase the sustenance of the inhabitants and provide the alternate sources of income through development of nurseries, small scale industries and exports.

14.1 INTRODUCTION

The efforts for harnessing the natural resources for sustainining the human race have been ‘on’ since the beginning of the civilization. The basic needs of food, fuel and fodder are obtained from the land resources with the combination of water and sunlight. The combination of information technology and use of hi-tech equipments paved the way for the introduction of precision horticulture. Precision horticulture may be defined as application of a holistic management strategy that uses information technology to bring data from multiple sources to bear decision associated with agriculture production, marketing, finance and personnel. Enhanced input efficiency is an important component of horticultural production under precision horticulture site specific management. Enhanced input efficiency in crop management can be obtained only when suitable varieties, desired amount of nutrients and water based on calculations, at right time and by proper method are used.

With recent advances in geographic positioning system, remote sensing, data processing, harvesting equipment, fertilizer and pesticide applicators, the approach can be used from a more practical stand point to identify variability and to use the variable rate of inputs over an entire field.

In recent years, there is considerable awareness about the nutritional security and food safety. More emphasis is given to underutilized fruits due to their high nutritive and medicinal value in addition to being resistant/tolerant to many biotic / abiotic stresses. The demand of these fruits are gradually increasing owing to tremendous potential for commercial exploitation aimed at improving the economic status of the poor and marginal farmers. An area, which needs immediate attention, is the collection, documentation, conservation and utilization for their sustained production and popularization.

15.1 INTRODUCTION

Vegetables are rich sources of many essential micronutrients, including vitamin C, vitamin K, folate, thiamine, carotenes, minerals, and dietary fibre. In addition, vegetables are rich in health related phytochemicals, such as antioxidants. Such phytochemicals play an important role in reducing the risk of many chronic diseases. Therefore, it is essential to produce more vegetables to feed our ever growing population. In this context, use of genetically improved, disease resistant and high yielding varieties in precision farming may play a significant role in increasing vegetable productivity and production.

15.2 EXPLOITATION OF GENETIC RESOURCES

The genetic resources of a crop may be defined as the sum total of hereditary material, i.e., all the alleles of various genes present in a crop species and its wild relatives. Genetic resources are broadly grouped into two major types (i) cultivated germplasm, and (ii) wild germplasm. Alternatively, they may be termed as (i) indigenous (from the country in question), or (ii) exotic (from another country) based on their place of origin. Genetic resources consist the following five types of materials: (1) land races, (2) obsolete varieties, (3) modern varieties or varieties in cultivation, (4) breeding lines, and (5) wild forms and wild relatives.

16.1 INTRODUCTION

The world floriculture business has reached to almost over a $ 40 billion mark. It is continuously going through the rapid transitional changes to have more unique and competitive products of wide choice to the consumers. Netherland is ahead in floriculture trade. Throughout the year, a large number of ornamental commodities are imported in Holland and exported back to the countries for its retail and consumption mostly to the countries in the Gulf, Middle-East Asia and America. According to the statistical estimates worldwide, a large quantity is consumed in US and the other countries. For an example, the US alone consumes 100 lacs of cut flowers a day and approximately 4000 lacs every year, though it ranks only 17^th in per capita cut-flower consumption. The average Swiss spends Rs 4500 a year on flowers, nearly four times than that spent by the average American besides the fact that the consumption of fresh cut flower and foliage plant is on manifold increase every year resulting in the competition worldwide for growing of exportable eco-friendly products. At the same time there is great environmental consciousness towards transforming floriculture with “natural and unspoiled” system of having the exportable produce into a mass and its ease to transport to any distant market. The system relies greatly on the industry with extensive network of breeders, greenhouse managers, field workers, auction houses, sales representatives, shippers, and florists to offer consumers a variety of choices matching their taste. This is the fact that in the recent times, the commercial growers don’t rely on the nature to introduce the genetic mutation that will make them millionaires but depends on the art and scientific knowhow to create a novelty in its own. This has resulted in the seriousness and painstaking effort of the growers to produce the plants in new forms and shape to put forward a new plant with extra-ordinary marketable characteristics every year, e.g. compact chrysanthemum, kalanchoe, bromeliads, orchids, etc (Plate1) are some of the common products with an unusual and eye-catching hue in the European markets. Similarly, the consumers can purchase gerberas with blooms as wide as salad plates and roses with yard-long stems perfectly suited for valentine-day gifts which mainly they get produced under the specific and artificial environment created for a specific growth stages of the plant.

17.1 INTRODUCTION

Flower consumption is growing at an alarming rate of 20 per cent per annum at global level and India is, today, one of the world’s largest consumer base and fastest growing retail destinations. Commercial floriculture is today a potential money-spinner and an economically viable agri-business.

Cut flower trade in terms of export oriented units dealing with rose and gerbera is flourishing. Other cut flowers like gladiolus, tuberose, lilum, chrysanthemum, etc. are also being cultivated along with traditional loose flowers like jasmine, rose, crossendra, marigold on a higher scale. However, growing awareness of Indian consumers and popularity for cut flowers is creating demand for diversified flower crops. Further, trade of some flowers in the market is responsible for gluts. Thus, there is an urgent need to diversify the floriculture industry by introducing and adoption of anthurium as a cut flower with unique shape and high longevity.

Precision farming is an advanced approach for the flower growers to enhance their income. It mainly includes information and technology of farm management system to identify, analyze and manage variability within fields for optimum profitability, sustainability and protection of the land resource. Precision farming is applied for increasing efficiencies that can be realized by understanding and dealing with the natural variability found within a field.

Anthurium is taking a good place in market with high value. Farmers are undertaking anthurium cultivation and in this direction, precise farming technology will help the farmers to grow the crop with good quality and higher production per unit area.

18.1 INTRODUCTION

Organic farming systems have attracted increasing attention over the last one decade because they are perceived to offer some solutions to the problems currently besetting the agricultural sector. In the western world, organic farming is catching fast (Malik, 2000). Indiscrimpte use of chemical fertilizers, herbicides and pesticides have resulted in environmental and health hazards along with socio-economic problems (Padmadevi, et al., 2008). India is bestowed with lot of potential to produce all varieties of organic products due to its diverse agro-climatic regions. In several parts of the country, the inherited tradition of organic farming is an added advantage. Organic farming is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture “is the successful management of resources for agriculture to satisfy changing human needs while maintaining or enhancing the quality of environment and conserving natural resources”. All definitions of sustainable agriculture lay great emphasis on maintaining an agriculture growth rate, which can meet the demand for food of all living things without draining the basic resources. Organic farming is one of the several approaches found to meet the objectives of sustainable agriculture. Many techniques used in organic farming like intercropping, mulching and integration of crops and livestock are not alien to various agriculture systems including the traditional agriculture practised in countries like India. However, organic farming is based on various laws and certification programmes, which prohibit the use of almost all synthetic inputs, treated seeds and health of the soil is recognized as the central theme of the method. Adverse effects of modern agricultural practices on the farm resources and health and over all survival of living being have been well documented all over the world. Application of technology, particularly in terms of the use of chemical fertilizers and pesticides has been serious concern. Their negative effects on the environment are manifested through soil erosion, water shortages, salination, soil contamination, genetic erosion, etc. Organic farming has the potential to provide benefits in terms of environmental protection, conservation of non-renewable resources and improved food quality. It is very important to maintain long term soil biological activity, ensure effective peak management, recycle wastes to return nutrients to the land, provide attentive care for farm animals and handle the agricultural products without the use of extraneous synthetic additives or processing in accordance with largely acceptable standard and applicable standards of destination country/ countries. Organic farming has several advantages over the conventional one apart, from the protection of both the environment and human health. Improved soil fertility, better water quality, prevention of soil erosion, generation of rural employment, etc. are some of them.

19.1 INTRODUCTION

Indiscriminate use of agro-chemicals over the last five decades has adversely affected soil fertility, crop productivity, produce quality and particularly the environment. These degenerative effects of intensive agriculture have compelled to think for alternative and sustainable system of agriculture. As a result, number of alternative systems viz Biodynamic, Rishi Krishi, Panchagavya Krishi, Natueco Organic Farming, Homa Organic Farming, Natural Farming and Jaivik Krishi have emerged in different parts of the country. In organic farming production is achieved without use of chemical input (Singh, 2011 and Malik, 2000). In these systems, maximum reliance is placed on self-regulatory agro systems and locally available or farm derived renewable resources. Since the soil, water and environment have been contaminated, hence even organic production techniques once effective are now are not capable of mitigating these issues. This has created number of myths in the mind of policy makers and even large number of farmers.

20.1 INTRODUCTION

With rapid increase in area under micro irrigation, now fertigation is getting momentum in many states in the country. At present, most of the soluble fertilizers are imported in the country. Hence, these are very expensive and beyond the reach of common farmers. It is interesting to record that for number of nutrients, which are becoming constraints in most of the Indian soils, soluble formulations have yet to be developed. This calls for some alternative options. As an alternatives liquid manures like cow urine, biogas slurry, or fermented manures etc can be sprinkled on the soil, applied with irrigation water or diluted and sprayed as foliar fertilizers (Frank et al; 2005).To our understanding, organic fertilizers /organic liquid manures referred now as bio-enhancers are essential to maintain the activity of microorganisms and other life forms in the soil. These are prepared locally, can resolve number of apprehensions and will be helpful in boosting production and mitigating number of nutritional disorders in most of soils and crops. It is interesting to record that these can be prepared at the farm with some infrastructure facilities and hands on training. Most of these formulations are used through irrigation. These organisms (bacteria and moulds) improve the soil health by solubilzing the complex organic substrates into simple forms and make it available to the plant, resulting in increased productivity. If these are integrated with micro irrigation techniques after proper filtration their efficacy can further be improved.

Cow dung and urine are important component in organic farming. Cow dung is rich source of microbial consortia Actinomycetes, which are helpful in control of many plant diseases. A potential species Streptosporangium psedovulgare of Actinomycetes and four strains of Bacillus subtalis have been identified at CISH, Lucknow (Pathak et.al., 2009).These showed anti pathogenic potential against anthracnose gummosis, stem end rot and dieback pathogens. These were observed to attack mycelia cell wall and finally the host cell degenerates completely. Organic liquid manures play a key role in promoting growth and providing immunity to plant system ( Sreenivasa et al., 2010).

21.1 INTRODUCTION

High population pressure has forced us to plough 46 per cent of our country area for food production. The present productivity is 12.36 tonnes/ha of fruits needs to be raised to 40.0 tonnes/ha by using N : P₂O₅: K₂O with other inputs, since recommended ratio is 0.75:0.50:1.00 only.

Since cost of the inputs like fertilizers and manures are very high, hence, efficient nutrient management is essential for sustainable fruit production and protection of the environment from different types of hazards occurring due to misuse of costly fertilizers.

The soils of India and especially of arid and semi-arid regions are impoverished to plant nutrients. Considering economy, energy and environment, it is imperative to use nutrients effectively by adopting the appropriate doses proper, placement and correct timings of application and to sustain the available nutrients in soil at the optimum level.

22.1 INTRODUCTION

The life-styles, economic conditions and food habits have a great effect on food marketing. There is an increasing demand for fresh fruits and vegetables and their processed products. Fruits and vegetables are processed into a variety of products and it is required to be picked at its right stage. For making juice, fruits should be picked at ripe and soft stage, for canning purpose it should be picked at fully mature but firm just before ripe stage. Fruits and vegetables are passed through a long channel before their consumption; which may lead to a number of undesirable changes in their composition. Thus effective post harvest management of fruits and vegetables is essential to provide their acceptable quantity and quality worth consumption. In this regard handling, processing and preservation and value additions form important loci.

23.1 INTRODUCTION

Mandarin oranges are the most popular among the citrus fruits and alone occupy more than 50% share under widely divergent citrus crops grown across the globe. In India, oranges have a place of prominence among fruit kind after mango and banana. It’s delicious, relishing, nutritious and handy fruits offer best mouth feel especially during summer when other fruits fail to quench thirst of throat. There is a need of scientific handling so as to accentuate trade and to exploit market potential of mandarin fruit.

Country wide, orange covers an area of 5.02 lakh hectares and the production is of the order of 43.96 lakh tonnes accounting for 12.03% and 6.40 % share under total acreage and production respectively in the fruits (Anon., 2010). Orange’s production in developed countries is projected to grow at an annualized rate of 0.6 per cent and that in developing country at 0.8 per cent.

In Rajasthan, ‘Nagpur’ mandarin and ‘Kinnow’ fruits occupy a place of prominence among various citrus crops grown. Cultivation of ‘Nagpur’ mandarin is mainly concentrated to Jhalawar district where it covers about 6040 ha area producing 87586 tons fruits, annually. After the implementation of National Horticulture Mission the area is further increasing steadily in the district.

24.1 INTRODUCTION

Citrus fruits occupy third position after mango and banana in the country and ranks 6^th in the world citrus production. The productivity, however, is only about 40 percent of that in Spain, Brazil, USA or Japan (8.4 t/ha) only. Of the total production, mandarin contributes more than that of sweet orange in which major chunk of 57.72 per cent was shared by Maharashtra, followed by 19.81 per cent by Madhya Pradesh state. At present, the Brazil is the largest producer of citrus, followed by USA. There are number of issues which need to be addressed to make fruit quality comparable to the international standards. Post harvest losses of fruits are also enormous mainly due to unscientific method of harvesting, lack of utilization of post-harvest handling techniques due to which 25 - 30 per cent losses occur in developing countries in comparison to 5 - 10 per cent in developed countries. Synergistic effect of pre-harvest practices and post harvest handling is the key to get the fruit of high quality and enhanced shelf life.

Recent trends are emerging as use of less chemicals and Good Agricultural Practices (GAP) during cultivation. Maintenance of quality standards and regulations up to retail market level is of utmost importance. Whereas, in marketing sector, now-a-days participation of private players on large scale in retail marketing of produce is noticed.

Value chains have become the centre of considerable academic and practical interests. Part of the reason for the rapidly growing interest in value chains in the citrus sector has been the result of changes in global retailing. In a large number of countries, supermarkets chains now dominate food retailing. Supermarkets have increasingly integrated their operations involving many aspects of the post farm gate operations. Value chain management is one of these. Some identified issues relates to supply chain bottlenecks resulting in farmers experiencing gluts of commodities, processors not being able to procure sufficient raw materials for their plants, retailers not getting sufficient products to meet the demand of consumers, and exporters are unable to meet foreign consumer requirements. Lack of innovation that affects the entire chain, an example being the introduction of plastic crates for a fruit processor involves a vast number of actors in the chain to coordinate their efforts.

25.1 INTRODUCTION

With the natures gift, consciously or unconsciously human select the best among the lot based on sensual judgment. Warnings about the dangers of the excessive use of the chemicals for the human health and biodiversity have been well reported over the years. The world health organization estimates the occurrence of some more than 25 million cases of excessive chemical use slow poisoning globally each year (Anon, 2010). In developing countries, sulphur and chlorine based formulations are often used for post-harvest treatments of horticultural produce. Recently, some bio-based and other safe post-harvest treatment materials have been formulated for loss reduction and shelf-life extension of fresh fruits. In this article, the recent and safe materials/agents for postharvest treatments are discussed.

25.2 MATERIALS FOR POST–HARVEST TREATMENTS

25.2.1 Polyamines

Polyamines (PAs) are low molecular weight small aliphatic amines that are ubiquitous in living organisms and have been implicated in a wide range of biological processes, including plant growth, development and response to stress (Smith, 1985). In plants, they have been implicated in a wide range of biological processes, including growth, development and abiotic stress responses. The most common polyamines are Putrescine (PUT), Spermidine (SPD) and Spermine (SPM) found in every plant cell in titers ranging from approximately micromolar to millimolar, together with the enzymes regulating their metabolism and depend greatly on environmental conditions, especially stress.

26.1 INTRODUCTION

India is the second largest producer of fruits and vegetables and ranks next to Brazil and China, respectively. With the commensurate total production of 63.5 and 87.2 million tonnes of fruits and vegetables, the country shares about 11 per cent of total production under fruits and 13 per cent of total production under vegetables, respectively (Anon., 2008) in global scenario. Horticultural produce undergoes spoilage at the time of harvesting, handling, storage, marketing and processing resulting in huge wastage. Efficient management of this waste can help preserving essential nutrients of our food and feeds and bringing down the production cost of processed product, besides minimizing pollution hazards and purifying the environmental condition. Recycling of horticultural waste is one of the most important aspects of utilizing it in a number of new ways to yield new products and meeting the requirements of essential products required to mankind.

In advance countries like USA, Australia, Brazil and Israel, more than 50 per cent of fruits and vegetables productions are processed into different products, whereas, in India it is less than 2.0 per cent of total production. Generally, post harvest losses in fruits and vegetables range between 25-30 per cent of total production, valued at more than 57,000 crores annually due to lack of availability of appropriate post harvest infrastructure (Guleria and Verma, 2008). Horticultural crops are grown all over the country incurring wastes everywhere. There are different stages of waste from farm to fork.

27.1 INTRODUCTION

In India, the horticulture sector contributes around 29 per cent of the GDP and 37 per cent of the total exports of agricultural commodities from about 13.08% of area. India has been placed as the second largest producer of fruits and vegetables; largest producer and consumer of cashew nut, tea, spices; third largest producer of coconut; fourth largest producer and consumer of rubber and sixth largest producer of coffee in the world. Several new programmes area in operation and significant developments in area expansion, production, value-addition and exports have taken place. Today, as a result of better synergy between research agencies, technological and policy initiatives by the governmental agencies, proactive participation of private players and higher degree of diversification to horticulture, this sector has emerged as a sustainable and viable proposition for even the small and marginal farmers including different stakeholders in the commodity chain. In spite of the remarkable progress made in the horticulture Sector in India, there is lot of scope in improvement in safety and quality aspects of horticultural produce.

The concept of biosafety encompasses a range of measures, policies and procedures for minimizing potential risks likely to appear to the environment and human health. Such safeguards must be put in place now. Biosafety is currently being promoted in a variety of ways by industry, governments and civil society. Quality and safety become prime concern because most of the horticultural produce are consumed daily in fresh, cooked and processed form and contribute major share in our daily diet. To ensure biosafety and quality of horticultural produce we need to ensure: a)Supply of quality inputs, b)Adoption of good cultural practices, c) Handling and processing of horticultural produce in scientific /hygienic manner, d)Packing, storage, transportation and delivery etc. in such a way that it reaches at consumers’ table without deteriorating the quality.

To ensure such aspects various preventive and certification measures have been initiated by government and certification agencies all over the globe including India , such as prevention of Food Adulteration Act 1954, Agricultural Produce Marketing Act, 1937, Food Safety Standards Association of India (FSSAI), Food Safety System Certification (FSSC:2200), International Food Certification (IFC), Food Chain Traceability, Hazard Analysis and Critical Control Point (HACCP), Food Product Orders (FPO), etc. The major emphasis under these certifications/regulations is to ensure quality and safety of the produce and minimize the risks by reducing the biological, chemical, physical hazards like microorganism contamination, level of heavy metal/chemicals/ drugs beyond the critical limits, residual effects of toxic substances etc. Brief of a few certification/regulations are listed below.

28.1 INTRODUCTION

Precision Farming has assumed great significance in the country for making the use of available resources more judiciously and efficiently. It is farm management strategy which utilizes precise information to increase profit and to reduce enviornmental impact. It takes into account in field variability in soil fertility and crop conditions. In nutshell, it may be defined as management of input variables such as application rates, cultivars selections, tillage practices, irrigation scheduling, optimization of soil and plant nutrient through nutrient management practices and management of pest and diseases by reducing the quantities of pesticides. Development of new technologies has become integral part of precision farming.

Precision farming was widely accepted firstly as a management practice in corn belt of mid west United States of America which helped in increasing the yield and significant reduction in production costs. Besides, crops like wheat and soybean have also been included in its purview. In south east parts of U.S.A., research is currently on in the crops of citrus, cotton, groundnut, vegetables and even livestock. Precision farming management practices have also integrated controlling and monitoring of field information using geographical information system (GIS), Global Positioning System (GPS), sensors, Variable Rate Technology (VRT) and yield monitoring. These components are highly sophisticated. GIS software stores data pertaining to soil type, nutrient levels etc in layers and assign that information to the particular field location. It can also be used to analyze characteristics between layers to develop application maps or other management options. Global Positioning System is a referencing device capable of identifying sites within a field. Global positioning system (GPS) helps in storing information regarding field location in terms of latitude and longitude. Maps showing variability of nutrient levels soil types, topography, pest incidence and yield can be created by virtue of it. It is a set of 24 satellites in high altitude orbit above the earth for pin pointing objects on the surface of the earth. These satellites continuously transmit radio signals which are picked up and deciphered by special receivers. A GPS receiver requires at least four satellites to determine its position on earth. Receivers are mounted on tractors/top of cab or on some high point to get a clear view of the spy. Crop stress, soil properties, pest incidence etc. are determined by the help of sensors through traveling over the field by tractors or combine. These can be used for measurement of soil conductivity, fertility status, weeds etc. Another type of sensor viz Remote sensors (aerial/ satellite) can provide instead maps of field conditions. Computer control device and associated hardware are part of Variable Rate Technology (VRT) for application of fertilizers, pesticides etc on the basis of field characteristics of the specific location. In precision farming, information is needed about mean characteristics of small, relatively homogenous management zones. It is data acquisition of the farms to find the soil, vegetation and other parameters which are amenable to remote sensing. Remote sensing techniques are helpful in providing continuous acquired data of agricultural crops. Remote sensors image vegetation growing on different soil types with different water availability. The following applications can be made by relief sensors:

29.1 INTRODUCTION

Some historians believe that it was women who first domesticated crop plants and thereby initiated the art and science of farming. While men went out hunting in search of food, women started collecting seeds from the native flora and began cultivating those of interest from the point of view of food, feed, fodder, fibre and fuel. This view is strengthened by the fact that women have been traditionally seed selectors. Even today this tradition has continued in many parts of the developing world. Women have played and continue to play a pivotal role in the conservation of basic life support system such as land, water, flora and fauna. They have protected the health of the soil through organic recycling and promoted crop security through the maintenance of varietal diversity and genetic resistance. In many hill and remote areas of developing countries such as Himalyan region, agriculture is largely in hands of women. Men tend to go to towns and cities in search of salaried jobs for fulfilment of family income. Therefore, without total intellectual and physical participation of women, it will not be possible to popularize alternative systems of land management for shifting cultivation, arrest gene and soil erosion, and promote the care of the soil and the health of economic plants and farm animals. Women also tend to look at problems in their totality from the sowing of the crop to its ultimate utilization either as food, feed or raw material for industry. Since they are usually involved in of marketing, they generally possess a clear understanding of market preferences and prejudices. Therefore, for an economically and ecologically sustainable agriculture the involvement of women farmers and farm women (agriculture farmers with and without assets) in the process of modernization of farming practices and village industries is absolutely essential. Horticulture is a major part of Indian agriculture. Although belated, their importance has now been recognized in India not only to provide the much needed balanced nutrition and gainful occupation to our populace but also to develop viable internal and export trade. Fruits like banana and vegetables like potato being energy rich are considered prominent food crops e.g. banana can produce as high as 37 million calories per hectare. Unfortunately the component of fruits and vegetables in Indian diet is hardly six per cent which should be raised at least five times so that the per capita per day consumption mathches the recommended dose of 85g. fruits, 75 – 125g. leafy vegetables 85g. other vegetable and 85g. roots and tubers. To achieve this present production of fruits and vegetables would need to be pushed up considerably by increasing the production levels and the area both.

Abstract

Since pre-historic times plants have tendered their services to mankind in the form of food, shelter and medicine. Due to the advancement of human civilization, various folklore systems of medicines were developed across the globe. Among the various folklore system of medicine, Sowa-Rigpa” is one of the oldest well recognised and widely accepted system of folk-lore medicine in the world. It is one of the commonly used of system of medicine in different parts of Tibet, Bhutan, China, former Soviet Union (some parts), Himalayan ranges, Magnolia and, Nepal. The exact origin of Sowa-Rigpa system of medicine is still not known. In the present scenario due to the awareness among the people about the determental effects of the modern chemical drugs, people preferred to use herbal based system of medicine to treat diseases. So, it is needed to understand the floristic wealth of tradional system of medicine to identify the important plants with potential source of drug candidate molecules. In the present chapter an attempt has been made to study the folklore plants used in Tibetan Mountain based Sowa-Rigpa system of medicine and food. Total 332 plant species presented as the most important in Sowa-Rigpa system of medium.

Abstract

The Khasi tribe of Meghalaya depends on wild medicinal plants for curing a number of ailments since ages. The traditional knowledge systems which evolved through trial and error method are an integral part of their culture. The objectives of the present study were to highlight the medicinal plants used by the Khasi tribe to treat various diseases, provide scientific validation of the medicinal plants by pharmacological screening using secondary literature and suggest strategies for its sustainable management. A total of 363 plants distributed in 283 genera and 129 families were documented. The life forms of these plants were in the order of herb > tree > shrub > climber > parasite > epiphyte. The herbal remedies for treating various ailments are prepared by using the whole plant either individually or in combination with other plant parts. Cross validation with the help of secondary literature showed the presence of active compounds in these plants. Therefore, it is suggested that traditional knowledge should be properly documented and scientifically explored with more emphasis on species specific phytochemicals and their mode of action.

The mode of application of herbal formulations varies from tribe to tribe. Herbaceous communities belonging to 160 species were the frequently used plant groups followed by trees, shrubs, and lianas. The decoction was recorded as the most frequently used method of preparation. Medicinal plants sold in the market was not primary for local people rather herbal plants locally available used as food, spice and beverages preparations. Therefore, there is a need for proper documentation and conservation planting of these unique medicinal plants growing in the Himalayas.

Abstract

Asteraceae is one of the largest family of flowering plants and have been used by mankind for a variety of purposes including food, medicine, cooking oils, sweeteners and tea infusions. In India, Asteraceae is 4^th largest family of angiosperms and ranked third among dominant families of angiosperms in Arunachal Pradesh. The indigenous communities of Arunachal Pradesh possess a rich knowledge on utilization of the plant resources around them for food, fodder, medicine and other purposes. Due to the remoteness and inaccessibility, the indigenous communities are mostly depended on their traditional medicines using plant resources around them for treating minor and major ailments. The effectiveness of these plants in traditional medicine has also been confirmed after isolation and characterization of the bioactive compounds responsible for their pharmacological activities. The present study is a review on ethnomedicinal plants belonging to Asteraceae family that are being used by different tribes of the state. The tribal communities have been using 36 medicinal plant species from this family as recorded from published literature and field study. Maximum number of species have been found to exhibit antimicrobial, antioxidant, antihelminthic, analgesic and anti-malarial properties. Among the recorded species, Ageratum conyzoides, Spilanthes acmella, Artemisia nilagirica, A. maritima, Blumea balsamifera, B. lacera, Eclipta prostrata, Vernonia cinerea and Chrysanthemum indicum were already being used in Ayurveda, Unani, Siddha, Homeopathy, Folk and Sowa-Rigpa systems of Indian Medicine. Therefore, the study highlighted the pharmacological potential of ethnomedicinal plantsfrom Asteraceae family which would provide opportunities for future drugdiscovery.

Abstract

Family Apiaceae (or Umbelliferae) is one of the largest plant group represented by 418 genera and 3257 species (TPL 2013). The plants members are mostly aromatic, used by local populace as traditional medicines as well as spice and condiments in their routine food preparations. They have characteristic aroma due to the presence of some essential oils or oleoresin. Members of this family possess large number of compounds having antibacterial, hepato-protective, vaso-relaxant, inducing apoptosis and antitumor activities. Although the family is distributed globally but Indian subcontinent is a major center of its diversification, where more than 200 species are distributed specifically in the Himalayan eco-terrains. Jammu province (Jammu and Kashmir, India) in North Western Himalaya having unique climatic conditions supports a large variety of medicinal and aromatic plants, and amongst these Apiaceae are well known. Local people uses these plants as vegetables, for culinary purposes and valued as traditional medicine like Bunium persicum (black cumin), Carum carvi (caraway), Coriandrum sativum (coriander), Cuminum cyminum (cumin), Foeniculum vulgare (fennel), Narthex asafoetida (Heeng), Trachyspermum ammi (ajwain) and Centella asiatica (Brahmi). People in Jammu province have their unique traditional way of using plants, knowledge of which is being transferred from generation to generation through oral dialect. As the data on the numbers of Apiaceae is scattered in the literature and difficult to be procured by the researchers. Therefore the current attempt is made so that the data along with some quantitative statistics can be provided at one platform only.

Abstract

Traditional knowledge on plants and their uses by tribal indigenous culture is helpful in the conservation of biodiversity.

Floristically, a total of 57 species belonging to 54 genera and 38 families were investigated to be used as medicine, food, fodder, timber, fuel wood, vegetable/edible fruit, resin yield and herbal tea purposes. On the basis of the floristic analysis of the study area, the leading family recorded was Asteraceae with (11%) species co-dominated by Rosaceae (9%). In terms of habit forms, herbaceous (70%) growth form is the most dominant. The most frequently used plant parts are leaves (26%) followed by whole plant (23%) and roots (19%). The plant documented cured different categories of diseases, the most common diseases such as diarrhea, fever, digestive problems, urinary troubles, rheumatism, eye diseases, skin diseases and wounds. Based on investigated knowledge, the data are discussed under sub-head as single, double and multi-diseases curing plants. The present study can provide a baseline data for future researchers, policy makers, common public, land managers, and the other stakeholders to develop scientifically-informed strategies for conservation of natural resources and sustainable use of plant resources in hotspot regions like Himalayas and other similar biodiversity rich sites.

Abstract

Ladakh, a geographically isolated region, is known for its tough terrain and harsh climatic conditions. It remains cut off from rest of the country for 6-7 months in a year during winters. With limited food, fuel and other resources the people here have developed and sustained a long unique relationship with plants. They have been using both cultivated and wild ones as medicine, food, and fodder since centuries. The local populace possesses good knowledge of traditional methods of utilization of plant resources for diverse purposes, which they have acquired from their ancestors. However, this indigenous knowledge and age old practices are fast disappearing from the tribal communities, and there is an urgent need to save this treasure from getting irretrievably lost. Therefore, the present study is an attempt to document the various wild and cultivated plants along with their ethnobotanical uses as per the ancient practices of these tribal communities. For this purpose, an ethnobotanical survey was conducted in various villages of lower Ladakh. The investigation revealed a host of plants put to use by the natives in different indigenous ways. The scientific, family and local names of 50 species belonging to 48 genera and 31 families along with their uses have been enlisted in the present communication. As per the information gathered from the local inhabitants, these plants are categorized into five different groups. More than 50% of these are used as medicines, 38% are edible, 24% as fuel and 20% as fodder. Approximately 38% plants are employed in construction, as ornamentals, or sources of dyes, incense, cosmetics, etc.

Abstract

Natural plant products are known to prevent several deleterious diseases. This potency of plants to act as medicinal therapeutic source is due to the presence of various bioactive compounds including alkaloids, phenols, flavonoids and glucosinolates (GSLs). Among array of these compounds, GSLs are important class of plant secondary metabolites. The mechanical or physical injury to plant leads to the activation of this “GSL-myrosinase” system resulting in the formation bioactive compounds viz., thiocyanates, nitriles, isothiocyanates, and epithionitriles. Out of these compounds, isothiocyanates (ITCs) are well known for their therapeutic properties. Allyl isothiocyanate (AITC) commonly known as “mustard oil” is one of the naturally occurring ITC which is derived from hydrolysis of sinigrin, the major GSL in cruciferous vegetables like horseradish, wasabi, brussels radish etc. Due to high bioavailability in human body, it has been widely studied for its important bioactivities. Therefore, this review highlights the significant biomodulatory effects viz., antioxidant, antimutagenic, in vitro, in vivo anticancer, antimicrobial, and insecticidal activities of AITC.

Abstract

Demand for horticultural commodities is increasing over a period of time. There is increasing pressure on available land for growing of such crops. The production of quality fruits, vegetables and other horticultural crops can be enhanced either by increasing productivity, use of improved cultivars/hybrids and effective production system, bringing additional land under horticultural crops or by promotion of protected cultivation which supports production in adverse climatic conditions and off seasons. Among horticultural crops, production of vegetables, flowers, medicinal and aromatic plants under protected condition is the best alternative to use the land and other resources more efficiently. Greenhouse cultivation is useful and is in practice in all kinds of climatic conditions, may it be severe and extreme cold (Canada and Russia), intolerant summer (Israel, UAE and Kuwait), excessive rains (Phillippines) and in moderate climate in several other countries. Nursery production of crops under protected conditions is highly economically viable.

The area under protected cultivation was only 0.23 per cent of the total area under horticultural crops in India in 2012. To boost up this, a number of varieties are bred for cultivation especially under polyhouse conditions. Greenhouse for vegetable production encompasses glasshouse, polyhouse, insect-proof net house, low tunnel polyhouse and zero energy polyhouse. Protected structures are of different kinds, viz. open-ventilated; closed polyhouse with fan and pad system; shade net house; sloped roof, rain shelter etc. Micro-irrigation has proved its efficacy in saving water, improving the yield and also is responsible for reducing diseases which develop in rather moist conditions. Protected structures appeared as the best means and are being used by many nursery growers for multiplication of healthy planting materials and are becoming popular especially in the hilly regions. Use of techniques like soilless culture, production of high value and low volume flowers and vegetables, hybrid seed of important vegetable crops and grafting of promising varieties on desirable root stocks can be made more efficiently under protected environment. Seed yield of many crops can be 3-4 times more under cover compared to their open field cultivation along with ensured quality.

Protected cultivation technologies in Himalayan high altitudes of India for the welfare of the soldiers and the society are a landmark in cultivation of horticultural crops in non-conventional areas. The protected production system has the potential to contribute greatly for achieving high productivity and stability to production in the present scenario of climate change. Extension of growing/harvesting period including off season is another desirable feature associated with protected cultivation.

Abstract

Limits to crop production are shrinking land area under cropping, shortage and higher cost of irrigation water, fertilizers, pesticides, electricity, labour wages and harvest and post harvest losses due to non-availability of cold chains and storage spaces. Diversification of crops to high value products is yet to gain momentum. Restrictions in marketing due to APMC acts are to be reviewed and drafted farmer-producer friendly. Forcing of horticultural crops-vegetables, fruits, flowers, spices, aromatic crops-to market fresh produces during off season is getting attention and many such units are established as a part of urban and peri-urban horticulture. Ready to assemble forcing structures are now available. Hi-tech nurseries, integrated soil and water management through fertigation, pests and disease management by bio-pesticides, predators and parasitoids, pheromones and light traps are successfully demonstrated. Space saving horticulture focuses on maximization of productivity and minimization of inputs costs in an eco-friendly and sustainable way.

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.

Abstract

High Tech interventions begin with acute desire and demand for high productivity and profit from Agricultural activity. High Tech cultivation implies judicious use of space, time and inputs; nothing more and nothing less. It is interesting to note that the different components that were listed in each case above are known to scientists and extension workers and to a lesser extent to farmers also. Piecing them together to formulate a practise is the novel thing. The major components of high tech cultivation assume the highest priority by virtue of the fact that the country has shortage for water and fertilizer and both are essential for any type of crops. Different components of high tech intervention can be used for growing crops, also for the growers to enhance production and quality .High tech intervention includes a number of components like- uniform virus free planting material, drip fertigation technology, assistance to post harvest management, and training and guidance to farmers, value addition opportunity, technical support to the farmers etc. These high tech interventions are introduced to other crops- a host of vegetables, fruits like Pomegranate, Cashew and Guava, and agricultural crops like, Cotton, Pulses, Sugarcane, and even cereals like, maize, wheat and rice. Another important aspect of such interventions is that only if concomitant interventions in marketing of produce are made, the whole exercise would bring profit to the farmers.
