In spite of considerable progress achieved during the last four decades in vegetable production in India, average productivity of vegetable crops is still low as compared to national and world level, indicating the scope to enhance their yield potential of quality produce. This is because of an appealing gap between potential yield and actual yield. In many vegetables, yield realized is even lesser than 50 % of potential yield. Sometime, farmers growing vegetable crops during main season do not get back their cost of cultivation. The prices of the same vegetable produce is very high during off-season. Several biotic and abiotic stresses are major factors responsible for low productivity and poor quality in different vegetable crops under open field cultivation, especifically in rainy and post-rainy seasons. The increasing demand of off-season high quality vegetables in various markets of big cities has called the attention of vegetable growers for diversification from traditional techniques of vegetable cultivation to modern systems of cultivation.

Protected cultivation of vegetable crops offers best choice for diversification. Production of crops under protected conditions has great potential in augmenting production and quality of vegetables, in main and off-season, maximizing water and nutrient-use efficiency under varied agroclimatic conditions. This technology has great potential especially in peri-urban areas, since it can be profitably used for growing high- value vegetables like tomato, cheery tomato, coloured Capsicum and parthenocarpic cucumbers, and healthy and virus-free seedlings in agri-entrepreneurial models.

Floriculture industry comprises of cultivation and trade of cut and loose flowers, potted plants, foliage and bedding plants, and dried flowers under open field as well as protected conditions. Globally, more than 145 countries are involved in cultivation of floricultural crops. Though the art of growing flowers is not new to India, protected cultivation is relatively new in India. Enormous genetic diversity, varied agroclimatic conditions, versatile human resources offer India a unique scope for diversification into new avenues which have not been explored to a greater extent. India also has a strong dry flower industry, which contributes a major share to the overall trade. Other segments like fillers, potted plants, seeds and planting material, turf grass industry and value-added products also contribute a share in overall growth of floriculture industry.

Cut flower production is a growing business in most of the Asian countries. Technology for production is well-known and it has been utilized to the maximum in many countries. As a consequence, cut flowers are commercially produced in larger quantities in these countries, resulting in surplus quantity during normal periods of blooming. On the other hand, such prices are much higher during the periods of needs such as certain special occasions, or off-season.

Kerala has a tropical humid weather characterised by high rainfall and humidity. The intense rainfall during June-September is a limiting factor for vegetable cultivation. High cost of labour, rapid urbanisation, small size of holdings and quality conscious consumers are some of the factors favouring protected cultivation in Kerala. Rain shelters and modified naturally-ventilated polyhouses are recommended structures for protected cultivation of vegetables. The important vegetables grown are cucumber, yard long bean, Capsicum, okra, tomato, cabbage, cauliflower and leafy vegetables. The conventional saw-toothed structure has been modified to suit Kerala weather by making variation in height and improving the roof and side ventilation so that temperature variation inside the structure is only 1°C compared to the ambient. The Kerala Agricultural University has also developed an ad-hoc package for protected cultivation of vegetables, considering the soil and weather parameters and is providing necessary technical support to growers and extension officers. The technology for large-scale production of virus-free vegetable transplants in pro-trays has also been standardized. There is a growing demand for quality, disease-free seedlings and technology can be scaled up into a profitable agri-entreprenurial model. Open field precision farming through fertigation and mulching is profitable compared to conventional system of cultivation. Besides maximising water-and nutrient-use efficiency of the crop, this technology offers scope for mechanisation in vegetable cultivation saving human labour requirement by almost 50%. Rain shelters are useful for year-round production of vegetables in homestead for small growers.

Protected cultivation was introduced in India during 1985 but its progress is slow during the last 25 years due to lack of suitable varieties and hybrids for protected cultivation. Presently, area under polyhouse in India is 2000 ha, therefore, knowledge of polyhouse vegetable production technology of tomato and cucumber with intervention of drip irrigation and fertigation along with suitable varieties will be quite effective for enhancing their productivity. Therefore, it is imperative to develop hybrid seed and production of suitable varieties/hybrids at affordable prices to small and marginal farmers to achieve the targeted production potential of vegetable crops. Keeping in view some genotypes were isolated and pure line and hybrid breeding programme were adopted for improvement of these genotypes. After three years of multilocational testing at tarai, midhills and higher hills under polyhouse condition, four genotypes were identified and released. They are: Pant Parthenocarpic Cucumber 2 (1,755 q/ha) and Pant Parthenocarpic Cucumber 3 (1,605 q/ha) of cucumber and Pant Polyhouse Hybrid Tomato 1 (1,616 q/ha) with average fruit weight of 130-140 g and Pant Polyhouse Tomato 2 (1,291 q/ha) of tomato with single fruit weight 100-105 g. These genotypes were released by Uttarakhand State Variety Release Committee during May 2011 for commercial cultivation.

India is the second largest producer of vegetable crops with a total production of 146.5 million tonnes (2010-11). More than 60 vegetable crops belonging to, Solanacious, Cucurbitaceous, Leguminous, Cruciferous (cole crops), root crops and leafy vegetables are grown in tropical, subtropical and temperate regions. The demand of vegetables will be 225 million tonnes by 2020 and 350 million tonnes by 2030. A larger quantity of quality seed of vegetable crops will be required in order to achieve the demands of vegetables. The limiting factors which reduce seed yield under open field condition are biotic and abiotic stresses, requirement of isolation distance and generation system of seed multiplication etc. These problems can be effectively managed when we go for seed production under protected structures.

Orchids are known for their exquisite beauty and trade in global floriculture business. The Netherlands is pioneer in roduction and ex ort of tem erate orchid while Thailand and Hawaii are the world leader in tropical orchids, respectively. Recently, Malaysia, Singapore, Thailand and Sri Lanka are catching the international market. The orchid industry is expanding in terms of magnitude in some of the major orchid-producing nations. The global orchid market has passed $ 1 Billion mark in 2010. The leading orchid producing countries in 2010 are:

Country Production ($ million) Japan 280 USA 170 Taiwan 130 China 70 Brazil 60 UK 45 Thailand 35 Italy 30 New Zealand 20 Source: Orchid News The world consumption of orchids (potted plants) is valued more than $ 500 million (2000). The Dominican Republic, Costa Rica and India have recently begun to produce orchids for export. Commercial production of orchids has increased dramatically through the world in the past quarter century. The most common genera sold in Japan from 1993 to 2002 were Phalaenopsis (30%), Nobile type Dendrobium (20%), Oncidium (20%), Cymbidium (15%) and Cattleya (10%). The potted orchids sold through Dutch flower auctions increased from 50, 0000 to 18 million pots.

The beginning of protected cultivation in the country has paved the way for export of horticultural produce, especially of flowers to earn valuable foreign exchange. The technology also became handy for quality production of flowers and F₁ hybrid seeds for domestic and export markets. In view of the globalization of international market and tremendous boost that is being given for export of flowers, there has been a spurt in the demand for protected cultivation technology. Low-cost polyhouses are quite popular in the North-East and in the northern plains, flowers are being raised in polyhouses either for capturing the early markets or to improve the quality of seedlings. Several commercial floriculture ventures are coming up in Uttrakhand, Maharashtra, Karnataka and Tamil Nadu to meet the demands of both domestic and export markets. There has been a substantial increase in area under protected cultivation of different flower crops. Though there were initial hitches owing to the cost sharing, farmers of some states have taken maximum benefits of the existing schemes and adopted the technology. Protected cultivation technology is one of the most useful technology inputs which hold promise to transform Indian floriculture and bring in the “Colour Revolution”.

Nearly, 40 countries are involved in protected cultivation of flower and vegetable crops. New production centers are being added constantly, mostly from developing nations. Today, majority of production is from developing countries like Zimbabwe, Morocco, Kenya, Ecuador, Costa Rica, Mexico, Singapore, Malaysia and India. In developed world, USA has an area of about 6,000 ha under greenhouses which are mostly used for floriculture. The Netherland is traditional exporter of greenhouse grown flowers all over the world. Israel, the largest exporter of cut flowers, has wide range of crops under greenhouses. About 1,000 ha area is under protected cultivation. Approximately, 98% of flowers are grown under open field cultivation and hardly 2% under the greenhouse cultivation.

H orticultural crops are most important ones incurring huge amount of pesticides in our country. The intensity of esticides on them is highest per unit area. However research on integrated pest management has not matched the progress and problems of plant protection at large and protected cultivation in particular. The USA, UK, Israel and Russia, pioneers in protected cultivation, are able to harvest productivity of up to 500 tonnes/ha of tomato and 200 tonnes/ha each of cucumber and capsicum, while in India up to 300 tonnes/ha of tomato and 100 tonnes/ha each of cucumber and capsicum are obtained, has compared to normal open field where their yield ranges from 40 to 60 and 10 to 20 tonnes/ha in India, respectively.

The sustainability of an agro-ecosystem is represented by its ability to maintain a given level of productivity over time and a given quantitative-qualitative level of environmental resources (Loucks, 1977). The greenhouse is also a form of agro-ecosystem, where unlike other agro-ecosystems, environment has been adapted to crop in order to maximize its productivity. The greenhouse system has to take maximum advantage of natural benefits offered by location in certain latitudes while minimizing the disadvantages (Castilla, 2002). Higher productivity under such protected cultivation is attainable mainly on account of reduced competition, healthy environment, better nutrient management, increased surface area and longer crop duration. However, ideal and stable environment with warm, humid and abundant food under protected conditions provides an excellent platform for pest development often more than open field crops, leading to severe pest situations in greenhouses, as revealed by extensive surveys.

Fusarium wilt of carnation caused by Fusarium oxysporum f.spp dianthi causes severe yield losses under protected cultivation. For the management of Fusarium wilt, 27 isolates of Bacillus strains were isolated from the rhizosphere of different crops including carnation. Among various species of Bacillus, Bacillus amyloliquefaciens (BSC7) was identified as a most virulent antagonistic bacterial isolate. Studies on antagonism under Environmentally Controlled Scanning Electron Microscopy (ESEM), depicted the presence of rod shaped bacterial cells with biofilm formation at 44847x. Detection for the presence of antibiotic biosynthetic genes reflected the presence of surfactin, iturin, bacillomycin and fengycin genes. The 24 isolates of Bacillus spp. showed positive reaction for surfactin gene. Nineteen isolates were amplified for Iturin A gene except BS5, BS9, BSC1, BSC2, BSC11, BSD1 and BSD2. Strains of B. subtilis BS1, BS2, BS5, BS6 and BS8 expressed Bacillomycin D gene. The genomic DNA of strains BS1, BS2, BS4, BS6, BS7 BS8, BS11 and BS14 showed positive for Fengycin D gene. The isolate of B. subtilis BS2 showed positive reaction for four genes namely surfactin, iturin, bacillomycin and fengycin.

In vitro screening of Bacillus, B. amyloliquefaciens (BSC7), P. aeruginosa (P1) and T. viride (TV1) showed highest inhibition against F.oxysporum f.sp.dianthi to an extent of 55.95, 55.29 and 81.61 per cent over the control respectively. The antifungal activity of antagonistic B. amyloliquefaciens BSC7 and T. viride TV1 against F.oxysporum f.sp. dianthi was confirmed under ESEM by observing disintegration, lysis and structural abnormalities of the hyphae of the pathogen at the zone of interaction.

Global demand for cut flowers is increasing steadily at around 10 per cent per annum. The share of India in this flourishing trade estimate at over US$ 40 billion per annum is negligible at 0.4 per cent. Floriculture include cut flowers, pot plants, cut foliage, seeds, bulbs, tubers, rooted cuttings and dried flowers or leaves. At international cut flower trade, flowers such as rose, carnation, Chrysanthemum, gerberas, gladiolus, gypsophilla, liatris, nerine, orchids, anthurium, tulips and lilies are preferred. Roses, gerberas and carnation are grown in greenhouses. The open field crops are Chrysanthemum, roses, gaillardia, lily, marigold, aster, tuberose etc. In India, floriculture is emerging as an important economic activity, earning foreign exchange. It has become a potential farm income enterprise. The domestic markets for high-quality flowers have been growing at 10- 20 per cent per year for the last few years. India’s flower business is estimated to be worth $ 400 million at retail, and about $ 100 million in international trade. Flower exports are about $ 30 million, constituting mainly of roses and dried flowers. Both Central and State Governments have been more than proactive and have made large investments in this industry in assisting production and marketing.

A large variety of floricultural crops can be produced in protected environment as economic cash crops for the benefit of farmers. Problems associated with floriculture in hills are small, scattered land holdings and sparsely located population. There is a lack of irrigation facilities due to scarce availability of water resources; widespread natural vagaries like drought, hail storms, frost etc. There is a serious gaps in application of advanced floricultural technologies for improving quality and productivity; high pressure on land use for different purposes like cereal crop production, fodder production, etc. due to low per capita land availability; difficulty in technology dissemination due to difficult terrain, hostile climate, poor communication facilities and sparsely located population. Consuming markets within the state are very less which result in dependence upon distant markets of the county. There is a high post-harvest losses due to lack of modern post-harvest management system; very high temperature differentials in production areas and consumer markets; perishable nature of flowers, resulting in high post-harvest losses during transportation; and distant location of production areas from main roads. High cost of marketing, lack of organised system of marketing, lack of bargaining power with individual growers due to small production levels; inadequate availability of market intelligence to farmers resulting in imbalances in distribution of produce in different markets.

The Indian Society for Protected Cultivation (ISPC) has organized a National Seminar on ‘Advances in Protected Cultivation’ at the NASC Complex, DPS Marg, Pusa, New Delhi, on 21 March 2013, with an objective of collection and collation of scientific advances made in protected cultivation in India and dissemination of these among policy-planners, farmers, students, scientists, industry and other stakeholders. In spite of the fact that protected cultivation is in its state of infancy in the country in terms of scientific engagements, more than 120 delegates from distant parts of the country registered for the seminar besides good number of policy-planners, recognized names in agriculture and higher officials from industry particularly corporate associate life members of the society.

In the inaugural session, Dr Brahma Singh, President, ISPC and Chairman, Organizing Committee welcomed the Chief Guest Padama Bhushan, Dr R S Paroda, formerly Secretary and Director-General, Indian Council of Agricultural Research (ICAR), New Delhi and Chairman Haryana Kisan Ayog, Chaudhary Charan Singh Haryana Agricultural University , Hisar ; Guests of Honour Dr M M Pandey, Deputy Director-General (Agricultural Engineering), ICAR and Dr H S Gupta, Director, Indian Agricultural Research Institute, New Delhi, other dignitaries on and off the dais, delegates, press and media. He also highlighted that this seminar intended to review the advances made in protected cultivation in India with a purpose to accelerate the same. He emphasized that protected cultivation offers opportunities to earn more from the limited land, water and other resources. It also enables production of quality products which fetch more prices and pride, besides being a potential practice for provisioning disease-free quality planting material for horticultural crops.

High-yielding crop varieties and hybrids with tolerance to pests /diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed.

Eight cardamom hybrids, NKE 12 × MB 5 (1,499 kg/ha), MB 5 × NKE 19 (1,461 kg/ha), GG × NKE 12 (1,350 kg/ha), RR 1 × CCS 1 (1,245 kg/ha), CCS 1 × RR 1 (1,022 kg/ha), ASH (1,930 kg/ha), NKE 12 × GG (1,746 kg/ha), GG × NKE 19 (1,635 kg/ha), were identified for high yield and resistance to mosaic and rhizome rot diseases. Two unique mutants, AFg-3 and AFg-4, for powdery mildew resistance were isolated in fenugreek. In ajwain, AA 93 has been developed which flowers 40 days earlier compared to other varieties. Thirty- two elite saffron clones were selected and evaluated for fresh and dry weight of pistil, stiga and style length, and weight. CITH 125 (4.5 kg/ha), CITH 123 (4.3 kg/ha), CITH 124 (4.3 kg/ha), CITH 122 (4.0 kg/ha), CITH 12 (4.5 kg/ha), CITH 121 (3.9 kg/ha), CITH 107 (3.8 kg/ha), CITH 120 (3.8 kg/ha) and CITH 104 (3.7 kg/ha), having higher saffron yield were identified.

Cost-effective farming systems for spices cultivation for increasing production and productivity in different agro ecologies have been developed.

An organic package for production of black pepper, ginger and turmeric by applying farmyard manure, vermicompost, ash, rock phosphate, Azospirillum sp. and phosphobacteria and Trichoderma sp. and Pseudomonas sp. as biocontrol agents for disease control was developed. Further, a foliar spray of 1% solution of complex fertilizer 19 : 19 : 19 (N : P : K) during spike initiation period (April second week, May first week and May fourth week) during lean cropping season under irrigated condition enhanced black pepper (cv. Panniyur I) yield by 20–25%. Soil application of zinc up to 10 kg/ ha or foliar spraying of ZnSO4 (0.25%) and Borax (0.2%) twice (60 and 90 days after planting) was recommended for higher yield and quality for turmeric in zinc and boron deficient soil.

Among all the treatments, sprinkler and drip irrigation methods caused early sprouting; early flowering with increased plant height and more number of leaves and flowers/plant as compared to the control (rainfed). Also, stiga fresh weight, dry weight, length and saffron yield were improved in sprinkler and drip irrigation methods over the control. Raised beds resulted in early sprouting, early flowering with increased plant height and more number of leaves and flowers/plant.

A protocol for SYBR green based real-time RT-PCRfor detection of Piper yellow mottle virus and Cucumber mosaic virus infecting black pepper and Cardamom mosaic virus (CdMV) and Banana bract mosaic virus (BBrMV) infecting cardamom was developed. A native isolate of Phytophthora capsici (Is. No. 98-93) infecting black pepper was completely sequenced using next generation sequencing platform, Illumina-Solexa GA II. The sequence data was assembled by taking Joint Genome Institute’s P. capsici as reference genome. The treatment of black pepper cuttings with Carbendazim + Mancozeb (0.1%) was effective for the management of anthracnose disease in nursery.

The black pepper accession, 1114 (Kumbhachola), was tolerant to P. capsici. The accession was earlier found resistant to pollu beetle and drought. A new bacterial wilt disease on small cardamom was recorded in Wayanad, Kerala. The phenotypic and genetic characterization revealed that causative organism is Ralstonia solanacearum (Biovar 3 phylotype 1) and was 100% similar to ginger strain of R. solanacearum. Bacillus amyloliquefaciens (GRB 35) and Serratia marcescens (GRB 68) were promising for enhancing sprouting of rhizomes, growth promotion and reducing the incidence of soft rot and bacterial wilt diseases in ginger in the field.

Standardization of the drying techniques

In fennel five methods of grain drying were employed viz., shade dryer (30°C), sun dryer (35°C to 37°C), solar dryer (40°Cto 42°C), vegetable dryer (50°C) and multipurpose grain dryer (60°C). Fennel grains which were dried under solar dryer, gave maximum test weight (5.17 g), recovery (39.82 %) with lowest moisture content (61.30%) and highest taste marks (9.3) and colour marks (9.2).

Common name, symptoms of damage and management of diseases of major spices and condiments

The term plantation crops refer to those crops which are cultivated on an extensive scale in contiguous area, owned and managed by an individual or a company.

There are two groups of plantation crops namely coconut, arecanut, oil palm, cocoa, cashewnut dealt by Ministry of Agriculture and tea, coffee, rubber dealt by the Ministry of Commerce.

These are high value commercial crops of greater economic importance and play a vital role in improving Indian economy, especially in view of their export potential, employment generation and poverty alleviation particularly in rural sector.

High-yielding Plantation crops varieties and hybrids with tolerance to pests / diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed.

Three coconut varieties (IND 045S, IND 048S and IND 058S), two arecanut varieties (VTL 62-Shriwardhan selection and VTL7-Nalbari) and two selections of cocoa (VTLC 1 and VTLC 57) were identified for commercial cultivation. Coconut variety, Kalpa Samrudhi, was recommended for commercial cultivation in Kerala and Asom, and Kalpa Sankara and Kalpasree for coconut root(wilt)- affected tracts in Kerala. Molecular-markers associated with hybridity in coconut, dwarfness and resistance to root (wilt) and yellow leaf diseases were utilized. Homology-basedmodelling of somatic embryogenesis receptor-like kinase (SERK) protein in coconut, development of a computational tool for detection of microsatellites in whole genome sequences, development of algorithm for gene annotation and genome-wide analysis of microsatellites in strains of plant growth promoting (P. fluorescens) are achievements in bioinformatics.

Cost-effective farming systems for plantation crops cultivation for increasing production and productivity in different agro ecologies have been developed.

In coconut-based cropping system, elephant-foot yam cv. Gajendra yielded high amount of corm. Guinea grass (var. GGCo 3) produced higher green fodder (89.2 tonnes/ ha/year) under husk application. There was lower specific volume of soil and soil porosity (higher soil compaction), and soil dehydrogenase activity (an index of biological activity) as important abiotic pre-disposing factors in incidence of root wilt disease. Growing Gomphrena globosa as intercrop in root wilt- affected coconut gardens has been shown to be cost-effective and sustainable. In areca-based mixed farming system, total cash inflows and outflows from arecanut + dairy (3–4 milch cows) amounted to ‘4.41 and ‘5.96 lakh, with a net profit of’1.55 lakh. The system productivity of arecanut + cocoa system (3,127 kg/ha) was 30% higher per unit area than arecanut alone (2,405 kg/ha). Integrated nutrient management on four improved arecanut varieties recorded highest chali yield (4.19 kg).

Crop protection research has brought out tangible and effective methods to suppress various pests in major agro-ecosystems. Indigenous knowledge in this regard has been tested and validated for its suitability.

Among the 137 Phytophthora isolates collected from bud rot/fruit rot affected coconut gardens in Tamil Nadu, Kerala and Karnataka, four isolates from bud rot affected gardens were identified as P. nicotianae and one as P. capsici. Since, P. nicotianae is found associated with bud rot disease of coconut in three districts representing three states, it is expected that this may emerge as a major pathogen of coconut. Further, placing Trichoderma coir pith cake in the innermost leaf axils of coconut palm in disease endemic areas just before the onset of southwest monsoon (May-end) and thereafter at two months interval was found to be very effective in the management of bud rot disease of coconut.

Technique to collect fresh and hygienic inflorescence sap (Neera) from coconut

In the traditional method of collecting sap, the inflorescence to be tapped is connected with an earthen pot/bamboo receptacle for the sap collection. Spadix to be tapped is tied with plastic rope and a small portion is sliced off from the top. The spadix is gently stroked with a mallet in the morning and evening. After a period of 8 to 10 days, sufficient sap starts oozing out from the cut end. A type of clay soil, a gummy material or leaf extract is pasted on the surface and sides of the cut end. Since the sap is highly nutritious, both enzymatic and microbial fermentation takes place. The total sugar reduces progressively and it becomes more acidic and develops a harsh odour and becomes unpalatable. In order to prevent fermentation, lime is coated inside the pot. The above method is not hygienic and attracts lot of insects, ants and contaminates from pollen and dust particles. In order to collect the sap fresh and hygienic, a simple device was developed.

Introduction

Medicinal Aromatic Plants (MAPs) play a valuable and important role in economic, social, cultural and ecological aspects of local communities the world over.

According to World Health Organization (WHO) “a medicinal plant is plant which, in one or more of its organs, contains substance that can be used for therapeutic purpose, or which are precursors for chemo- pharmaceutical semi-synthesis”.

However, a simplest definition of the medicinal plant would be “Medicinal plants are those plants which are used in official and various traditional systems of medicines throughout the world”.

Other definition could be “Medicinal plants are plants that provide people with medicines - to prevent disease, maintain health or cure ailments”.

In Indian traditions, all the plants in this earth are considered as medicinal [Jivak in Astanga Hriday (Sutra: 9-10)].

Aromatic plants are a special class of plants used for their aroma and flavour. Many of them are exclusively used also for medicinal purposes in aromatherapy as well as in various systems of medicine.

A high-yielding cultivar Vallabh Medha of mandukparni (Centella asiatica) was identified. Fresh herbage yield (12,331 kg/ha) and dry herbage yield (2,113 kg/ ha) of this variety were far more than the local variety (2,050 and 392 kg/ha respectively), besides higher active ingredients. Among mucuna selections, IIHR PS 15 with long duration, IIHR PS 6 with medium duration and IIHR PS 14 with short duration recorded significantly higher yield and high L-dopa yield/ plant. In Coleus, a promising hybrid, Hy 08-53, recorded significantly higher root yield (60.22g) and higher forskolin yield/plant (0.58 g). In ashwagandha, IIHR- WS 3 was found to be the best yielder (11.65 q/ha).

Isabgol (Plantago ovata Forsk.)

The crop requires cool and dry climate during the growing season. Sowing of seeds at 4 kg/ha in 0.25-0.50 cm depth during November 20 to December 20 was recommended. In medium black cotton soil of Malwa region, second week of November was reported to be optimum time for sowing. Broadcasting of seeds followed by light sweeping with broom found to give uniform germination. A spacing of 30x 45 cm found to be most ideal to get higher seed yield in Isabgol under Madhya Pradesh situation. Response of chemical fertilisers was found low. However, a fertiliser dose of 25 kg/ha each of N and P₂O₅ as basal dose and 25 kg/ha N as top dressing at 30-42 DAS was recommended for commercial cultivation in Gujarat while 50 kg/ha N reported to increase the seed yield in Madsaur areas of Madhya Pradesh. At Anand three irrigations viz. first at the time of sowing and subsequently at 30 and 70 days after sowing (DAS) proved to be beneficial. However, four irrigations at sowing, 10,25, and 50 DAS at Mandsaur are recommended. Chemical weed control was found to be economical and a pre-sowing or pre-emergence application of Isoproturone (0.5 kg ai/ha) was recommended for weed control. One spray of Metalaxyl + two sprays of Mancozeb were found significantly superior in controlling downy mildew. In Gujarat, Pearl millet in Kharif and Isabgol in Rabi season are advocated as a suitable crop rotation. Groundnut-Isabgol rotation gave higher economic return followed by Soybean-Isabgol and Pigeon pea-Isabgol rotations in Maharashtra.

Azadiractin (1%) was found effective for the control of Hadda beetle on Ashwagandha. Nineteen arthropods were recorded on isabgol. Among them, 13 were phytophagous species belonging to order Lepidopteran (09), Hemipteran (03) and Homopteran and six predatory species belonging to order Coleoptera (03), Neuroptera (01) and Odanata (02). The sequential occurrence of arthropods revealed the presence of aphid (Aphis gossypii) from second week of January to fourth week of February, whereas Lepidopteran (Helicoverpa armigera, Trichoplusia ni, Thysanoplusia oricalchae, Spliarictia sp. Hyposidra successari and Olene mendosa and true bugs (Graptostethus servus and Spilostethus pandurus) were observed associated during early crop growth stages (i.e. from second week of December). Infestation of aphid was uniformly severe, whereas that of Lepidopterans and true bugs were sporadic and less severe. However, presence of these pest arthropods caused significant reduction in seed yield.

Green energy can be classified as any form of energy resource that results in zero greenhouse gas emissions and zero toxic byproducts. These constitute the alternate source of energy such as Solar, Bio, Hydrogen, Wind, Water etc. Renewable Energy is energy that is not depleted or expen- ded. Previously the pressure to reduce CO2 emissions dictated the energy sourcing. With recent findings from experimental evidence, global warming may not be attributable to CO₂ emissions in relation to other over-weighing causes. However the pressures to develop renewable sources continue since the cost of Oil is increasing in many countries. It is desirable and a necessity to develop renewable non-toxic energy resources. The global economy and welfare of all earth depends on it even if CO₂ is not the cause of global warming (GW). There are some factors not in the control of even the most technologically advanced society. These are solar activity such as sun spots which have huge and tremendous influence on the Earth’s climate. However we should strive not to cause any undue imbalances in the proportion matter and composition of Earth’s atmosphere. Although CO2 is a small contributor to GW in comparison to H₂O, we still have responsibility to maintain the right balance of the gases in the atmosphere by not causing undue changes to the Carbon, Nitrogen and Oxygen cycles! We are far way off from a Oil-free technology. Most transportation is still petrol driven.

Sustainability has recently become an important factor in the engineering world. Landscape architecture is a discipline that attempts to improve the way humans interact with the environment. That interaction can be improved in various ways such as water conservation, energy conservation, or urban planning. landscape architecture encompasses urban design, community and regional planning, interior and exterior garden design, parks and recreation, historic site and natural area preservation, energy and water conservation, landscape restoration and management, among others. The varied list is an example of the dynamic essence of landscaping and provides insight into the many areas which can be improved by implementing sustainable practices.

Sustainable development practices aim to protect the quality of life of future generations. This can only be done by understanding how the natural environment operates as well as how human interactions affect it. Sustainable Landscape Architecture focuses on enhancing the holistic knowledge of the surrounding landscapes, including the complex processes which naturally occur to maintain it. Employing this knowledge within the planning phases of development should result in the reduction of negative environmental impacts due to the same. The traditional consequences of land development can be eliminated or mitigated when developers are able to foresee the consequences of their work. Many times, replicating undeveloped conditions and/or native landscapes within the overall site design will prove very useful in achieving the goals of sustainability. All of the sustainable topics covered in this chapter involve the application of a technology that resulted from better understanding the natural environment.

3.1. SOLID WASTE MANAGEMENT

Solid waste management includes the transportation, processing, recycling and disposal of our waste materials. We live in a disposable world in many ways with the modernization and convenience of our world we have cluttered it with our refuse.

Green business, is enterprise that has no negative impact on the global or local environment, community, society, or economy—a business that strives to meet the triple bottom line. Often, sustainable businesses have progressive environmental and human rights policies. In general, business is described as green if it matches the following four criteria:

1. It incorporates principles of sustainability into each of its business decisions.

2. It supplies environmentally friendly products or services that replace demand for non-green products and/or services.

3. It is greener than traditional competition.

4. It has made an enduring commitment to environmental principles in its business operations.

A sustainable business is any organization that participates in environmentally friendly or green activities to ensure that all processes, products, and manufacturing activities adequately address current environmental concerns while maintaining a profit. In other words, it is a business that “meets the needs of the present world without compromising the ability of the future generations to meet their own needs.” It is the process of assessing how to design products that will take advantage of the current environmental situation and how well a company’s products perform with renewable resources.

Tourism is a phenomenon, which has taken off immensely in the past three decades. It concerns us all, be it by allowing us to travel long distances as tourists, or by forcing upon us a mass of visitors to our part of the world. In the past, people did not travel half as much. Financial obstacles and responsibilities to land and animals stopped them from doing so. Only in 1845 did Thomas Cook of Leicester, England, organize the first package tour, making this experience available to people outside of the privileged classes by cutting down on expenses. By 1939, an estimated one million people were traveling abroad each year. Nowadays, the population of the Mediterranean swells to double over the summer, from 130 million resident inhabitants during the winter to 260 million in high season. There were about 698 million international tourist arrivals worldwide in 2000. All regions in the world grew, and the fastest developing region continued to be East Asia and the Pacific. Tourism has become the largest industry in the world. And just like all thriving industries, though it has a lot to give, it also takes a lot in turn. Unfortunately, the toll that we pay for it has been rising steadily. While the prospect of people traveling less in the future seems improbable, to say the least, a new idea has already sprung up: If we cannot stop tourism, let us at least travel sensibly.

Landscaping is both science and art and is an aspect of the environmental impact of a hotel that needs to be addressed. Understanding and blending the elements of both nature and construction is effective landscaping. Whether Landscaping is extensive or small consumes a large amount of water, fertilizers and herbicides and generates solid waste.

Ecogreen’s Greenscaping Operation provides cost-efficient and environmentally friendly solutions for landscaping. Greenscaping operation deals with two aspects:

1. Solid Waste Management, and

2. Water Conservation

Trees are major capital assets in cities Just as streets, sidewalks, public buildings and recreational facilities are a part of a community’s infrastructure, so are publicly owned trees. Trees — and, collectively, the urban forest — are important assets that require care and maintenance the same as other public property. Trees are on the job 24 hours every day working for all of us to improve our environment and quality of life. Urban forest provides many environmental benefits to our community. Aside from the obvious aesthetic benefits, trees within our urban forest improve our air, protect our water, save energy, and improve economic sustainability.

In other words, since most trees have been planted much of the tree cover is in urban areas as opposed to “natural lands”. Therefore, estimated pollutant uptake rates are higher for residential compared to natural or unmanaged lands. Possible management implications of these estimates are that air pollutant uptake benefits from tree planting may be optimized by planting in areas where air pollutant concentrations are elevated and where relatively high planting densities can be achieved thereby enhancing the health of urban dwellers.

Pollution is the term used to denote the hindrances caused to living organisms by way of contamination of their physical environment. Pollution to air, water, soil etc. is the major problem faced by the living community. Measures to control the emission of pollution into air, water or soil will certainly reduce the level of pollutants. Mitigation of pollution can be best achieved by combining nature with technology that increases the effectiveness of plants in removing pollution. Use of vegetation is an effective means of pollution control and many researchers have reported their advantages in mitigating pollution.

So far, the main approach has been to dig the polluting chemicals out of the ground and transport them to a landfill. However, after a decade of research, scientists in the early twenty-first century found that hundreds of species of plants, along with the fungi and bacteria that inhabit the ecosystem around their roots, seek out and often break down chemical molecules that can harm most other life.

In the mid-1980s, Dr. B.C. Wolverton and fellow researchers at NASA conducted several studies to determine whether plants could halt indoor pollution and provide a natural way to deal with the problem. It has been suggested by NASA and the Associated Landscape Contractors of America (ALCA) that plants are major pollution-absorbing devices: the common indoor plants might provide a natural way of helping combat “SICK BUILDING SYNDROME”. Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. These plants are not only decorative, but are also surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings.

India has witnessed a phenomenal increase in foodgrains production since Independence and from a food deficit state producing about 51 million tons in 195051 it become food surplus country with a record harvest of more than 250 million tons in 201112. This particular year also saw a remarkable record production of pulses at about 18.1 million tons. However, to meet the increasing demand of the continuously rising population about 23 million tons of pulses have to be imported every year costing the country about Rs.3000 crores in foreign exchange. Despite the changes in the dietary habits in which the large middle class has moved away from traditional cereals towards high value dairy, meat, fruits and vegetable products, pulses in India are still considered an important source of proteins, particularly for the poor. Pulses are not only an excellent source of protein (2040%), carbohydrates (5060%) and minerals (24%) but also provide calories almost equal to that of cereals energy to the tune of 300 to 540 Kcal/ 100g (Ofuya and Akhidue, 2005). Thus, pulses play an important role in achieving food and nutritional security for small and marginal farmers. However, the per capita availability of pulses has been declining over the time – it has declined from 60.7 gm/ day in 1951 to about 32 gm/day in 2010 – mainly due to stagnant production (except in recent years), rising demand for consumption and other uses. Pulses not only are used for consumption, but also play an even greater role in maintaining and enhancing soil fertility through nitrogen (N₂) fixation. Though the estimates of Nfixed by pulses depends on crop species, soil type, agroclimatic zone and crop management practices, it was reported that early, medium and long duration pigeonpea varieties fix 7, 55 and 69 kg/ ha¹, respectively, in Vertisols of Patancheru (Kumar Rao and Dart, 1987). Pulses ^N2 are grown not only as sole crops but also as intercrops and the biological nitrogen fixation (BNF) of pulses substantially benefits the associated or succeeding crops in terms of nitrogen contribution (1668 kg/ N₂ ha¹ for succeeding cereals). Thus on a conservative estimate, the BNF (@46 kg/N₂ ha¹) by pulses, excluding the intercrop area, alone amounts to 1.06 million tons annually.

India is the largest producer of pulses in the world with 24% share in the global production. During 201011, the total production was 18.09 million tonnes from an area of 25.6 million hectare (Table 1). The important pulse crops grown in India are chickpea (48%), pigeonpea (15%), mungbean (7%), urdbean (7%), lentil (5%) and fieldpea (5%). The major pulse producing states are Madhya Pradesh, Maharashtra, Rajasthan, Uttar Pradesh, Karnataka and Andhra Pradesh, which together account for about 80% of the total production. The pulses production does not keep pace with the domestic requirement and consequently, the nation has to import 23 million tonnes and the per capita availability of pulses has declined progressively from 41.6 g in 1990 to 37 g in 2008 (Indian Council of Medical Research recommends 65 gm/day/capita). Thus, increasing production from the current level poses a serious challenge for the nation.

Even with the best of efforts, pulses production and productivity has more or less remained stagnant. Due to the low productivitylow input nature, pulses are grown as residual/alternative crops on marginal lands after taking care of food/income needs from high productivityhigh input crops like rice and wheat by most farmers. Also, they grow as rainfed crops with little or no modern yield enhancing inputs. The low priority accorded to pulse crops may be related to their relatively low status in the cropping system. As a crop of secondary importance, in many of these systems, pulse crops do not attract much of the farmer’s crop management attention. In deficient soils, the application of micronutrients has also been found to be remunerative, yet the farmers hardly use these inputs. Seeds of newly developed varieties are not available to the farmers in the required quantities. As a result the seed replacement rate is hardly about 2 to 5%. In addition to this, these crops are adversely affected by a number of biotic and abiotic stresses, which are responsible for reduced yield. Lack of onfarm storage facilities and the vulnerability of pulses to store grain pests also results in considerable losses. Stray cattle and blue bulls are responsible for a lot of damage to the pulse crops especially during offseason, thus affecting adversely the cultivation of crops like mungbean, urdbean, pigeonpea, fieldpea and lentil in Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan and Haryana also resulting in instability and low yields.

Pulse production in NE states in still too low as compared to whole India. However, there is very good potentialfor enhancing pulse producity in the region and contribute to food grain production of the country. In view of these constraints, prospects for increasing pulse production from this region have been visualized.

Pulse production scenario

Despite immense importance of pulses in humanand animal nutrition, the share of north-easternregion inthe total pulse areofIndiaistoolow (0.76%)andthisregion contributesonly176.44 thousandtons(0.99%) in the all Indiapulse production (Table 1). WithinNE Region, mostof the pulsearea isoccupied by Assam and 47% of total N.E. Region’s pulse production is contributed by this state alone. After Assam, Nagaland and Tripura are major pulse growing states with 33.5 and 14.5 thousand hectares of area and 36.46and 24.20thousandtons ofproduction, respectively. In Meghalaya, pulseswere grownon4 thousandhaarea and4.2 thousand tonnesof pulses wereharvested in 2010-11. Thefactthat theaverage pulse productivity of NE region (883.0kg/ha)is much higher thanthatof whole India (689kg/ha) offers opportunityfor increasingarea and production of pulses in the region.
