INTRODUCTION

Strelitzia is known as Bird of Paradise. The uniquely shaped flower of this exotic tropical resembles a head of bird and due to its brilliant orange and blue colour and unusual form, it resembles not any bird but a bird of paradise. Its another common name, Erane flower is another bow to its exotic avian shape. Fantastically handsome flowers aside, this is also a very attractive foliage plant resembling the related heliconia in vegetative appearance. Due to the brilliant colour and unique appearance of the flower, it is exceptionally popular as a cut flower which appears periodically throughout the year. Therefore, it is cultivated in different countries for cut flower production to supply it in local and export markets. Commercial production of cut bloom is done in California, Hawaii, Israel, France, South Africa and Japan.

Bird of paradise occupies a place of pride in the garden and is an important choice for landscaping. It is grown in backyard and also for mass effect. Plants of strelitzia can be used in the landscape in a low growing ground cover to enhance the beauty of garden. They serve well anchoring island beds when surrounded by lower growing annuals or ground cover. It can also be used in shrub borders and adaptable beauty is perfect for home and commercial interiors.

Zingiberales is an important order in Kingdom Plantae with eight families in which most of them are important as far as commercial horticulture is concerned. The order includes fruits (bananas and plantains), spices (ginger, turmeric, cardamom), medicinal (arrowroot, galangal) and ornamental (Heliconias, Bird of Paradise, Marantas, Canna, Costus, etc) plants. Among the ornamental zingiberales, plants of Strelitziaceae and Heliconiaceae are gaining popularity for its aesthetic preferences and marketable cut flowers. The unique colour and enhanced vase life of inflorescences makes them as flowers of choice. The plants of other families such as Marantaceae, Cannaceae, Costaceae, Zingiberaceae, Lowiaceae and Musaceae are also gaining momentum in floriculture business for their cut foliages and inflorescences. Some plants such as calathias are admired as potted plants and for indoor gardening.

Bitter gourd (Momordica charantia) is a widely grown vegetable variety in India. It is one of the important members of the family Cucurbitaceae. The seed production can be done throughout the year in tropical climate and during spring, summer and rainy season in subtropical climates. In Tamil Nadu September – October is suitable for seed production. In hills seed production can be done during summer season.

Bitter gourd (Momordica charantia L., 2n = 2x = 22, family Cucurbitaceae, monoecious, cross-pollinated but genetically behaving like self-pollinated crop), also known as balsam pear, bitter melon, bitter cucumber, and African cucumber is rich source of vitamin C and iron and credited with medicinal use in management of diabetes. Fruits are cooked with other vegetables, stuffed, stir-fried, or added in small quantities to beans and soups to provide a slightly bitter flavor. The bitterness of most cucurbits is mainly due to cucurbitacins. The bitterness of bitter gourd is due to the cucurbitacin-like alkaloid momordicine and triterpene glycosides (momordicoside K and L) as reviewed by Behera et al. (2010). Bitter gourd is grown on approximately 340,000 hectares across Asia, with India and China accounting for more than half the production. Estimated area of bitter gourd in India is about 80,000 ha with production reaching to 10,00,000 resulting into a productivity of 12 tons/ha. States accounting for major area of bitter gourd are Chhattisgarh, Telangana, Andhra Pradesh, Orissa, Madhya Pradesh, Uttar Pradesh, Bihar, Tamil Nadu, Haryana and Assam.

It is rich in iron and Vit –C and native of tropical Asia particularly eastern India and Southern China (Sheshadri 1986 Mini Raja et al., 1993).
 
Botany: Monoecious annual, staminate flowers small, yellow and borne on slender pedicel. Pistillate flowers solitary have small pedicel, flowers are yellow, leaves segmented pentamerous. Filaments 3, two are bilocular and one is unilocular. There are three short styles ended with three bilobed or divided stigmas.

Chromosome 2n=22: 6-centromere in middle, 3-submedian, 2-subterminal  (Vargheuse, 1973)

Germplasm

KAU-Vellanikara, IIHR-Bangalore, NDUAT-Faizabad, CSAUAT-VRS, Kalyanpur, BPUA&T-Pantnagar and IARI- New Delhi are the major sources of bitter gourd germplasm.

Bitter gourd (Momordica charantia L.) is one of the important commercial cucurbitaceous cash crops grown mainly by small holding farmers in Asia where it is cultivated on more than 340,000 ha annually (McCreight et al., 2013). Eastern Asia, possibly Eastern India, or Southern China is most likely the center of origin for bitter gourd (Walters and Decker-Walters 1988; Miniraj et al., 1993). It is also known as bitter melon, bitter cucumber, balsam pear, bitter apple, or bitter squash (Morton, 1967). Fruits are known for abundant source of vitamins and minerals. Delicious preparations are made from fruits after stuffing and frying. It is also consumed in the form of Juice, Tea and Pills. Bitter gourd fruit abounds in phytonutrients (Dhillon et al., 2017) and often used to manage type 2 diabetes as a folk medicine. Clinical studies confirmed that elevated fasting glucose levels in pre-diabetics can be reduced by supplementing the diet with bitter gourd fruits. (Amirthaveni et al., 2018; Krawinkel et al., 2018). Medicinal properties present in the bitter gourd fruits are used in the curing of diabetes, asthma, blood diseases and rheumatism.

The current seed market of bitter gourd in Asia values ≈ 16 million Euros. The bitter gourd seed market in India alone is 400 metric tonnes having value of 350-400 crores. 70 % area is under hybrids and 30 % is covered by open pollinated varieties.

Bitter gourd or Bitter melon, Momordica charantia L under the family Cucurbitaceae (Chromosome no. 2n = 2× = 22) is widely grown in India, Indonesia, Malaysia, Singapore, Thailand, China, Japan, East Africa, the Caribbean and South America for its edible fruit. Tender fruits are widely used as cooked vegetables in a number of ways. Bitter gourd is an excellent source of vitamin C, iron, magnesium, potassium, calcium and ß carotene. The fruits contain non-toxic glycoside momordicin, which gives it bitterness and also health benefits. It also contains an insulin-like compound called Polypeptide-p or p-insulin and steroidal compound “Charantin” having hypoglycemic property.
Origin, domestication and adaptation in India
Wild or semi-domesticated variants spread across Asia in prehistorical period, and it was probably domesticated in Southeast Asia. It has probably originated in eastern India or Indo-Burma area or southern China. Uncarbonized seed coat fragments have been tentatively identified from the spirit cave in northern Thailand however, there have been no archeological reports of bitter gourd remains in China (Marr et al, 2004).Population resequencing revealed the divergence between wild and South Asian cultivars about 6,000 years ago, followed by the separation of the Southeast Asian cultivars about 800 years ago, with the latter exhibiting more extreme trait divergence from wild progenitors and stronger signs of selection on fruit traits.

Bivalve and mollusc hatchery techniques are fundamental to modern aquaculture, offering controlled environments to induce spawning, facilitate larval development, and ensure juvenile growth. These hatcheries serve as the cornerstone for sustainable mollusc farming by supplying consistent and high-quality seed stock. Key procedures in these facilities include broodstock conditioning, induced spawning, larval rearing, and juvenile cultivation, all tailored to maximize reproductive success and survival rates. Molluscs, particularly bivalves such as oysters, clams, mussels, and scallops, play a vital role in global aquaculture. Their cultivation is expanding rapidly due to their ecological services, including water filtration and habitat formation, alongside their high nutritional value and economic returns. Hatchery-based production enhances seed availability and reliability, addressing the variability of natural seed sources and supporting the expansion of commercial farming. Mollusc hatcheries are specialized facilities engineered to regulate and maintain optimal conditions for reproduction, larval development, and seed production. These operations are built upon scientific principles encompassing infrastructure design, water quality management, breeding protocols, and biosecurity measures. Induced spawning techniques, often triggered through temperature shocks or chemical cues, initiate gamete release under controlled settings. Larval rearing involves maintaining precise environmental parameters— temperature, salinity, and food availability—to support the delicate early developmental stages. Following metamorphosis, juveniles are transferred to nursery systems where they continue to grow until they are ready for transfer to grow-out sites. A distinguishing anatomical feature of bivalves is their two-valved shell, which may be symmetrical or asymmetrical and may fully or partially enclose the soft body. These shells are primarily composed of calcium carbonate and comprise three layers: the nacreous inner layer, the prismatic middle layer, and the outer

The silkworm chawki rearing is a vital stage in rearing as it has major influence on cocoon production.  Temperature, humidity and leaf quality are the three key important factors influencing chawki rearing.  Hence, maintaining these conditions at every step is very important and calls for provision of separate chamber. Any alteration in these factors will influence during later ages of silkworm rearing leading to crop losses.  Taking these factors into consideration the Government of India promoted the establishment Chawki Rearing Centres (CRCs) in private sector also.  These CRCs brush the silkworm eggs at one point under controlled conditions and distribute the worms to the needy farmers.
 
In recent years, bivoltine hybrids are becoming more popular in India and particularly in Karnataka.  This is due to the efforts of the Central Silk Board, Karnataka State Department of Sericulture and Japanese International Co-operation Agency.  These Bivoltines have high cocoon shell ratio (24 to 25%), better quality, fetches high cocoon price, better returns, high rendita (5.1 to 6.1) and raw silk percentage (20 to 22%) with filament length of 11502 to 12200 meters.  The farmers could achieve up to 70kgs cocoon yield per 100 Disease Free Layings (DFLs) and quality silk of 2A to 4A grade.

Black caraway (Bunium persicum Boiss. Fedtsch ) commonly known as kala zeera is a low volume,  high value, under-exploited and  non-perishable crop that finds place  in cold arid  North -Western Himalayan regions of Indian sub-continent. Its fruits are expensive spice and are used in indigenous system of medicine for curing various ailments and disorders. The proper information on botanical identity of the species, its description and distribution, active ingredients, standardized agro-techniques, processing and value addition and marketing potentials, etc. are very scanty. An attempt has been made to gather information on various aspects of kala zeera to promote its cultivation in the cold arid regions of the Himalayan states and its role in improving the socio-economic conditions of the people by cultivating the cash crop.

Introduction

Biomass is a major source of energy in developing countries, particularly in India. Biomass as a fuel used in residential sector of India is a major component of total energy use in India. Type of fuels used in residential sector in India varies with locations and availability of the local fuels and also by way of cooking food in the open fires or in the rural cook stoves (Earthen Chulhas). The majority of the household in the rural sector of the developing countries burns the biomass fuel under traditional open stoves or in advanced closed cook stove (Fullerton et al., 2008). Biomass fuel includes any material of plant or animal origin, which is deliberately burnt by the human being. Approximately, 2 billion people in the developing world use the biomass fuel as the major source of domestic energy (Balakrishnan et al., 2002). Out of residential fuels, 80-90% of the energy requirement in rural India are met with the use of biomass in the form of fuel wood, dung cakes, charcoal and agricultural residue (TEDDY, 2007). Burning of biomass from all these sources is well known to be associated with the emission of smoke/plumes consisting of particulate and gaseous species as these are not energy efficient processes and thus the fuels are not burnt completely. The species emitted and their concentrations depend on the nature of the source of biomass and other factors including the physical parameters associated with the consumption of the biomass. The fate of the initial fire emissions depends strongly on both their composition and the regional state of the atmosphere. Once airborne, the particles begin to grow slightly in size as they age through condensation and coagulation. Despite their high concentrations and widespread distribution in the atmosphere, the sources remain poorly characterized. Biomass burning has drawn global concerns in the past decades for its effects on visibility, human health and global climate by emitting particulate matter (PM) and other gaseous pollutants (Andreae et al., 2005). Biomass burning emits significant global source of PM emissions to the troposphere which leads to deleterious impact on the earth’s atmosphere. It has an impact on the chemical composition of the atmosphere, the formation of photo oxidants and thus on air quality on a regional scale and climate change (Andreae et al., 2005). They also have harmful impact on human health, natural environment and ecological system (Cheng et al., 2000). The various impacts of these emissions have been well studied by Cheng et al. (2000) and Bardouki et al. (2003). Interest in this topic grew when several studies suggested that biomass burning emissions could rival fossil fuel emissions (Crutzen and Andreae, 1990). Biomass burning has received considerable interest (Bowman et al., 2009).

Introduction

Black cotton soils are formed by the solidification of molten magma; it covers a large area of the Deccan plateau. The depth of this soil is very high in the lower part of the Krishna – Godavari basin. The clay fraction is very high which is responsible for the heavy waterlogging in the area of heavy rainfall and become more vulnerable to soil erosion. The fine fraction of soil not allows draining out through the soil profile and at the same time the rate of evaporation is low. During summer soils suffer from moisture stress and it becomes very hard but at the same time during the rainy season moisture content very high. this imposes severe constraints on conventional agriculture use as a result most of the land remains fallow and subjected to soil erosion due to heavy rain. The nutrient status of the soil is quite good in Vertisol but these constraints limit crop production. To manage black cotton soil for crop production it is advisable to use animal-powered devices for surface soil drainage, Counter cultivation, adoption of a new cropping system will be helpful for better crop production.

Black gram (Vigna mungo, L. Hepper, 2 n = 2 x = 22, family Leguminosae/ Fabaceae, essentially self-pollinated) has a global production of 3.2 million tons where India is the largest producer accounting for more than 70% of the global production followed by Myanmar and Thailand. Indian black gram area, production and productivity in 2010-11 were 3.25 million ha, 1.76 million tons and 522 kg/ha. The corresponding figures for 2015-16 were 3.62 million ha, 1.95 million tons and 537 kg/ha and the corresponding figures for 2016- 17 were 4.48 million ha, 2.83 million tons and 632 kg/ha. For 2017-18 (IV advance estimate), the figures were 5.44 million ha, 3.56 million tons and 655 kg/ha (Directorate of Pulses Development, 2018). These figures show a steady rise in black gram area, production and productivity over the years. This is the third important pulse crop in India after gram and pigeonpea. The three states namely, Madhya Pradesh, UP and Andhra Pradesh alone account for about 50% of the black gram area and production in India.

Black pepper (Piper nigrum L.), famous as “Black Gold” and also known the “King of Spices” is the most important agricultural commodities of commerce and trade in India. It is the most important, most popular and most widely used spice in the World. Of the total spices traded internationally, black pepper accounts for 34 per cent. South West India is the traditional home of this important spice, particularly the Malabar Coast. Black pepper is also grown in tropical zones such as the Asia Pacific Region, mainly India, Indonesia, Malaysia, Sri Lanka, Thailand, China, Vietnam and Cambodia. Outside the Asia Pacific region, the crop is distributed in Brazil, Mexico, Guatemala, etc., totaling about 26 countries. It is grown successfully between 20°N and 20°S latitude and from mean sea level to 1500 meters above sea level. World’s black pepper production varies in the range of 2.7 to 3.35 tonnes annually. The major production share is contributed by Vietnam with an annual production of 80,000 tonnes. About 85 per cent of the World trade of pepper is determined by the largest pepper producing countries in the International Pepper Community (IPC). World export fluctuates around 1.5–2.5 lakhs tonnes per annum. Global black pepper supply has shown a drastic increase over last ten years except in 2008–09. Vietnam’s sudden increase in production has resulted in the massive global out put of 3–3.5 lakhs metric tonnes from 1.9–2.0 lakhs metric tonnes in late nineties.
