Introduction

India is the second-largest producer of vegetables in the world after China. India accounts for 16 percent of the world’s production of vegetables. India home to 17.74% of the world’s population has only accounted for about 2.4% of the world’s geographical area and 4% of its water resources. Vegetables play an imperative role in nutritional security, economic viability and fit well into the predominant intensive cropping systems prevailing in different parts of our country. More than 60 kinds of vegetables are grown in India in tropical, subtropical and temperate agro-climates. India is the largest producer of okra and ranks 2nd in the production of potato, onion, cauliflower, and cabbage. During 2013-2014, India produced 162.19 million tonnes of vegetables and vegetable export from our country was worth Rs. 5462.93 crores. For a balanced diet, an adult who works moderately needs about 300 grams of vegetables per day, of which about 50 grams should comprise root vegetables, 50 grams of leafy vegetables and 200 grams of other kinds of vegetables as per Dietary Guidelines for Indians, NIN, 2011.

The vegetable is one of the important crops of Jharkhand, which is being cultivated on a commercial scale. About 3.2% of the gross cropped area of the State is devoted to vegetable crops. Vegetable development depends not only on production but also on the marketing system. Vegetable cultivation being labour intensive can substantially increase employment and livelihood avenues too. Vegetable growers face many challenges in the course of marketing their products and their marketing behaviour varies under different circumstances. Keeping this in view, the present investigation entitled “Marketing Behaviour of vegetable growers in East Singhbhum district of Jharkhand” was undertaken.

Identification of the insects is the integral part of systematics. It utilises all taxonomic procedures. The collections in the world are the accumulation of past taxonomists and are stored for the future identifications. Every species name is based on a published description or figure and usually on the type specimen. Identification is the association of other specimens with the appropriate description or with type specimen.

The steps in identification are as follows:

1. Preliminary key to orders and families

2. Key to genera and species if recent monographs or faunal works are available

3. Reference to the most recent catalogues

4. Reference to current bibliographies for literature published subsequent to the most recent catalogues

5. Reference to original descriptions

6. Comparison with the authentic described specimens or with types.

Concept of Delinting

Cotton seed clumps because of linters getting trapped on them after ginning. Gin-run seeds have very low flowability and do not singulate, making cleaning, upgrading, and precise metering in planting operations challenging or impossible. To singulate the seed and increase flowability, a variety of techniques have been and are employed. Most of the techniques entail removing the tags and linters entirely or partially, although other coating techniques have also been attempted with mixed results, both financially and technically (Mezynski, 1966; Webber and Boykin, 1907).

Methods of Delinting

1. Mechanical Delinting

Mechanical delinting is the usual technique used to improve the flowability of cotton seed. As previously indicated, mechanical delinting basically involves resharpening with finer, closer-spaced saws to remove part of the commercially valuable linters.

The livelihood in rural India mainly depends on agriculture in the form of various land-based enterprises like crop farming, livestock rearing etc. But the landless people in the villages depend mainly on agricultural wages. These landless rural resource poor possess own labour as the only abundant factor which is free to them and they try to use it to its maximum for their survival and thus concentrate on animal husbandry. Goats are kept as a source of additional income and as an insurance against income shocks of crop failure. In addition, the rural poor who cannot afford to maintain a cow or a buffalo find goat as the best alternative source of supplementary income and milk. Goats represent a more liquid form of capital than cattle and are readily tradable, hence goats are called as “poor man’s cow” in Indiabecause it will produce milk, meat and manure like cow at very low costs.Goats are also perceived to be a less risky to invest into compared to sheep. Goat rearing has significant effect in augmenting farmers’ income. Goats preferentially select plant parts that are higher in digestibility when stocking density is low. Tolerance of goats toward bitterness may play an important role in maximizing grazing capacity and in biological control of weeds. Goats will sustain and produce well under low fodder, low water and extreme adverse climate and it will produce well in terms of milk, meat, manure and hide. Goats are docile, good tempered, cooperative animals easy to rear by women, land less labour and children and they will thrive well on shrubs, bushes and kitchen waste. They are known as moving ATM because they will provide financial assistance to farmer thought the year in all situations.

Introduction
The genus Haemophilus contains small, nonmotile, nonsporing, oxidase positive, pleomorphic, gram negative bacilli that are parasitic on human beings or animals. Haemophilus means blood loving organisms.

Haemophilus species are small (less than 1 pm x 1 to 3 μm), Gram-negative rods, which often appear coccobacillary and may occasionally form short filaments. These motile organisms, which are facultative anaerobes with variable reactions in catalase and oxidase tests, do not grow on MacConkey agar. They are fastidious bacteria requiring one or both of the growth factors X (haemin) and V (nicotinamide adenine dinucleotide, NAD). Optimal growth occurs in an atmosphere of 5-10% CO2 on chocolate agar which supplies both X and V factors. Small, transparent, dewdrop-like colonies are formed by most Haemophilus species after incubation for 48 hours.

Colonies of H.somnus have a yellowish hue and some isolates are haemolytic on sheep blood agar. The main pathogens in the genus are H.somnus in cattle and sheep, H.parasuis in pigs and H.paragallinarum which is responsible for infectious coryza of chickens.

The haemophili are motile, facultative anaerobes, produce acid from glucose, reduce nitrates and are variable in the oxidase and catalase tests. They are nutritionally fastidious, will not grow on MacConkey agar and grow best on chocolate agar (supplying the X and V factors) under 5- 10 per cent CO2 at 37°C.

The growth of many of the Haemaphilus species is enhanced by 10 per cent CO2, As this is not inhibitory for any of them, CO2 should be used for routine isolation.The inoculated chocolate agar plates are incubated under 10 per cent CO2 at 35-37°C for 3-4 days, although some growth may be seen after 24 hours.

ABSTRACT

A detailed survey was carried out in all the 19 rural blocks of Birbhum district of West Bengal. Pisciculture is a powerful income generating activity (IGA) by the women Self Help Group (SHG) members related to poverty reductionand employment generation for a vast section of the rural society. Self Help Groups are non-formal cooperatives that are causing a silent revolution in rural India through micro credit and various other economic activities involving women are the major change agents. Nearly, thirty thousand SHGs have been formed in Birbhum district of West Bengal that had made a notable success in micro finance. This study has focused on the functioning of 38 women SHGs of Birbhum district comprising 644 members mainly belonging to Below Poverty Line family. Totally 38 SHGs have been selected for the study. Each group had it unique name and consists of about 10 to 18women members. Information was elicited from all the members of 38 women SHGs, which together formed 644 members, constituting the study sample. The data were collected with the help of semi-structured interview survey schedule. The survey was carried out during the year 2009. Different social class of these fisher women members of the SHGs were assisted under Swarnjayanti Gram SwarojgarYojana. These SHGs were found to save a portion of their meager income and pool that money for their inter-lending among them at an interest decided by the SHG. The survey revealed that cash credit and project loan was used for better sustainability and enhancement of income from pisciculture. Most of the cultural water bodies i.e. ponds were under lease condition. Self Help group members particularly belonged to scheduled caste community actively take part in retail marketing of fish in rural areas. Empowerment of women was undertaken through training and other assistance given by local Panchayat, NGOs and Govt. Officials. The SHG women members increase in self-confidence, leadership qualities, skill to undertake pisciculture and marketing, knowledge of book keeping, enhanced income, linkage with bankand protest against social injustice.

Manila tamarind (Pithecellobium dulce  (Roxb.) Benth.), also known as ‘Jangle jalebi’, ‘Madras thorn’, Sweet inga and ‘Monkey pod’ has a potential to become an important tree of semi- arid and arid regions since it is a drought hardy plant and tolerates harsh environmental conditions as well as salinity. In general, it is planted on the boundary of orchard, road and field sides as protective hedge plant. It is a medium size, much branched tree, suitable for silvi-pastoral system (Gupta et al., 1994). It is drought resistant species but susceptible to frost under arid conditions, coming up well in areas of low rainfall due to its extensive root system. Names like dulce (sweet) and “Manila tamarind” reflect the wide use of the pods as food. The most valuable and commonly used part of Manila tamarind tree is the pulp, which is white or red, very sweet and has a pleasant flavour. The large aril represents 50 per cent of the fruit (Seeds 25%, husk 25%). The major constraint in commercialization of this tree species is lack of improved genotypes, agro-techniques for cultivation in different ago-climatic conditions and limited commercial value.

Atoms and molecules are the essential building blocks of every object. The manner in which things are constructed with these basic units is vitally important to understand their properties and their reciprocal interactions. An efficient control of the synthetic pathways is essential during the preparation of nanobuilding blocks with different sizes and shapes that can lead to the creation of new devices and technologies with improved performances. Traditionally nanoparticles were produced only by physical and chemical methods. Some of the commonly used physical and chemical methods are ion sputtering, solvothermal synthesis, reduction and sol gel technique

Basically there are two approaches for nanoparticle synthesis namely the Bottom up approach and the Top down approach. In the Top down approach, scientists try to formulate nanoparticles using larger ones to direct their assembly. The Bottom up approach is a process that builds towards larger and more complex systems by starting at the molecular level and maintaining precise control of molecular structure.

These two different methods highlight the organization level of nanosystems as the crossing point hanging between the worlds of molecular objects and bulk materials.

The top-down approach has been advanced by Richard Feynman in his often-cited 1959 lecture stating that “there is plenty of room at the bottom” and it is ideal for obtaining structures with long-range order and for making connections with macroscopic world. Conversely, the bottom-up approach was pioneered by Jean-Marie Lehn (revealing that “there is plenty of room at the top”) and it is best suited for assembly and establishing short-range order at the nanoscale. The integration of the two techniques is expected to provide, atleast in principle, thewidest combination of tools for nanofabrication.

INTRODUCTION

Lotus is the foremost symbol of beauty, prosperity and fertility. According to Hinduism, within each human inhabiting the earth is spirit of sacred lotus. It represents eternity, purity and divinity and is widely used as a symbol of life, fertility, ever-renewing youth and to describe feminine beauty especially the eyes. Egyptians considered it a symbol of rebirth, since it closes in the evening and falls to the water, then reopening again in the morning, thus emulating the behavior of the sun. All lotuses are day-bloomers that open early in morning and close by mid afternoon for three successive days, with first flower closing earlier. It possesses an amazing ability to flourish in a variety of environment ranging from clear ponds to muddy marshes. The exquisite flowers with long herbaceous stalk arise from the rhizomatous stems and a flat and peculiar seedcase at its center.

Lotus, the national flower of India, has been a part of Indian culture, religion and history from ancient times. It is considered sacred not only by the Hindus of India but also by the Buddhists of China and Japan. To early Egyptians, a lotus bud or Sesen was a symbol of rebirth. Lotus is offered to Goddess Lakshmi and is considered as her symbol. Besides, lotus has found place in one of the postage stamps in India. Every year some prestigious awards are given to the distinguished personalities of the country like Padmashree, Padmabhushan, Padmavibhushan and Swarna Kamal (Golden Lotus).

India has an enormous wealth of cattle, which is crucial to the development of the socioeconomic status of millions of rural households as well as the country’s economy. In addition to giving millions of people access to lowcost nutritious food, this industry plays a significant role in boosting family incomes and creating gainful employment in rural areas, notably among landless laborers, small and marginal farmers, and women.

When green forages are dried to approximately 85% dry matter, they retain a significant portion of their nutrients, including carotene, and are referred to as hay. Compared to straw, hay is both more nutritious and more palatable. High-quality hay should exhibit a leafy structure, be pliable, possess a green colour and be devoid of mold, weeds and dust, while also emitting a pleasant fragrance. It is essential that the moisture content does not exceed 15% (ideally between 12-14%) to ensure safe storage without the risk of fermentation or combustion.
Objectives of hay production
The primary goal of hay production is to lower the moisture content of green fodder to a level that effectively inhibits the activity of both plant and microbial enzymes.
Benefits of hay production
• Hay serves as a nutritious feed source for livestock during periods of scarcity.
• High-quality legume hay can substitute for concentrates, thereby lowering production costs.
• Fodder can be harvested at optimal times to maximize nutrient accumulation in the plants.
Crops suitable for hay production: Fodder crops with soft and flexible stems are ideal for hay production. Green oats are considered the best option for this purpose. Other suitable crops include green berseem, lucerne, cowpea, stylo, and various natural grasses, provided that leaf shattering is minimized. Both annual and perennial grasses, such as anjan, doob, rhodes, and sudan grasses, are also appropriate for hay making. However, cultivated cereal fodders like maize, sorghum and bajra are better suited for silage production than for hay. If using thick-stemmed crops for hay, it is necessary to chop or crush them into smaller pieces.

Introduction
The modernization of farming systems across the country is transforming agriculture. Yet, public extension services often struggle to keep pace with the growing demands for knowledge dissemination due to widen gap between farmers and extension agent i.e., 5000:1 (Ragasa et al.,2013). Also, only 6.8% farmers receive extension services directly from state extension agency (GFRAS, 2012). The complexity of modern farming systems, encompassing decisions about land use, crop selection, and market access, underscores the importance of tailored specific knowledge. Strong public extension services typically reach only about 10% of farmers, a figure further constrained by limited operational resources (Bell, 2015). This gap is exacerbated by limited resources and infrastructure. In this context, Information and Communication Technology (ICT) emerges as a game-changer, offering innovative solutions to address these challenges and empower farmers with crucial insights. The integration of ICT in agriculture is revolutionizing the way knowledge and services reach farmers, especially in resource-constrained and remote regions. ICTs, such as mobile technology, have demonstrated significant potential in extending the reach of agricultural extension services. For instance, mobile hotlines now enable farmers to obtain technical advice and market information, including price updates and market locations (Aker and Mbiti, 2010). Such tools empower users, particularly in remote areas, to access vital information and communicate efficiently (Aker, 2011). To meet farmers’ diverse and specialized information needs, ICT-based models must bridge these gaps effectively. However, the success of ICT interventions depends heavily on affordability and the customization of information to address the highly localized nature of agriculture (McNamara et al., 2011; Bell, 2015).
Digital Choupal
Recognizing these challenges, Bihar Agricultural University (BAU), Sabour, has pioneered an innovative solution by introducing Digital Choupal through videoconferencing facilities at Krishi Vigyan Kendra (KVKs) and colleges of the university across the state. This initiative has supported agricultural extension by significantly reducing the barriers posed by distance and resource limitations. Bihar, a densely populated state in India with 1,102 people per sq. km, faces significant challenges in its agricultural sector. Employing around 75% of the workforce and contributing 35% to the GDP, agriculture remains a vital part of the state’s economy. However, technology adoption is slow, particularly in rural areas, due to poor connectivity and limited communication infrastructure. Less than half of Bihar’s villages are connected by roads, and access to trained extension personnel is scarce. These limitations hinder the dissemination of agricultural innovations and the provision of real-time advisory to farmers, which are essential for enhancing productivity and improving livelihoods. This innovative approach has redefined agricultural outreach, ensuring that even the most remote farmers can connect with experts and benefit from customized training and guidance.

Reducing the input costs in farming, especially agrochemicals and improving the yields of farm products in environmentally sustainable way, is one of the most important challenges. World over, the understanding of alternative eco-friendly inputs and intelligent integration of such products with the farming practices are the areas which need to be emphasized, understood and demonstrated. Our experience of working with farmers in different regions has convinced us that they all are looking for alternative, eco-friendly and cost effective inputs and the only way to convince them is practical demonstrations. 
Eco safe farming is a global challenge and needs combined efforts of NGO_s and farmers bodies, private and public sector industries and scientists in the institutions and universities. There are many challenges and many success stories and some typical once are listed here.

ABSTRACT

Information Technology includes computers and communication technology along with associated software. I.T. can be defined as the technology of creation, processing, storage, retrieval and transmission of data and information. Transmission of data and information between through local national, regional and global telecommunication channels are not new to us. Computer networks have been the real facilitators of data and information interchange in the individual and corporate levels. LANS and WANS are the good examples of it. Developing countries have a critical stake in how successfully they cope with the trade, environmental, energy, healthy, agricultural, industrial, population and other challenges facing them as they enter the information age. The World is experiencing an explosive growth of IT at the moment. There have been tremendous impacts of I.T. on the trade, commerce and industries of the globe.

For most people in their right mind, parasites are disgusting little creatures. The mention of them evokes images of tiny crawlers entering the body of innocent victims by devious means, encrusting themselves within various organs (often with very unpleasant effects), living off their host’s tissues, and then exiting the body, sometimes through scatological avenues, leaving behind hosts that are incapacitated, if not mere shells of their former selves (as is literally the case for some insects). The true facts are not always that gruesome (after all, parasites that have to spend a long time inside a host do not benefit if this host kicks the bucket, because then they die as well) but often enough parasitic reality is not pretty. Ask biology students about their parasitology course, and they will tell you that attending class is like visiting a little shop of horrors. I, for one, came out of my parasitology course with newly developed phobias (mercifully temporary) of such innocuous activities as eating meat and bathing in streams – they represent ways of transmission for some parasites. But students will also tell you that parasites are fascinating because of the complexity of their life cycles and the intricate ways in which they complete these cycles. So fascinating, in fact, that many students eventually become parasitologists and devote their entire lives to studying the little critters. Most of these people work with parasites of livestock or humans, but a few with an equal taste for ethology and ichthyology pursue the more esoteric questions that occupy this page: how fishes avoid getting parasitized, and how fishes alter their behaviour once they get parasitized (Barber et al., 2000)

7.1 Summary

Climate change is a complex global phenomenon that poses significant challenges for agriculture including uncertainty about future weather patterns, soil conditions, and other environmental factors. Farmers are facing the difficult task of interpreting and responding to these changes in order to maintain their livelihoods and ensure food security for growing populations. In this context, mental modelling has emerged as a useful approach for understanding how farmers interpret and respond to climate change. Mental models are cognitive representations of how individuals understand and make decisions about complex systems, and can be used to identify key drivers of behaviour and decision-making.

The present study has explored the social, ecological, and economic factors that influence farmers’ mental models on perception of climate change, level of uncertainty and trend of agricultural change in the selected study area. It argues that farmers’ mental models are shaped by a range of factors, including their own experiences and observations, social networks and interactions, access to information and resources, and broader economic and political contexts. The present study has also highlighted the role of uncertainty in shaping farmers’ mental models and decision-making. Uncertainty about the future impacts of climate change can create significant challenges for farmers, as they must make decisions based on incomplete information and uncertain predictions.

The current research work was carried out in the new alluvial zone which is one of the agro-ecological regions in the state of West Bengal. To conduct the study, three villages located in the Haringhata block of Nadia district were chosen randomly. A total of 90 farmers were selected with 30 respondents each from the villages of Kastadanga, JalkarBhomra and Subuddipur. Initially a list of contact farmers was collected from the Kastadanga SKUS and few contact farmers were selected randomly from the list. Afterwards Snowball sampling method was followed to select respondents.

Aquaculture is practiced in the majority of countries worldwide, however the significance of water quality standards remains largely unknown to farmers and new aqua entrepreneurs. They may achieve maximum fish production with minimal input costs if they are trained and stay up to date on water quality management in the aquatic ecosystem. The water quality categorised into three main of metrics as physical, chemical, and biological parameters. Dissolved oxygen (DO), biochemical oxygen demand (BOD), free carbon dioxide (CO2), pH, temperature, total dissolved solids (TDS), turbidity, ammonia, nitrite, nitrate, alkalinity, bacterial density primary productivity (chl a), plankton population, etc. play a significant role for fish production. However, even small variations in certain physical and chemical parameters—particularly pH, temperature, and dissolved oxygen (DO)—can cause stress in the animals, which may manifest as physiological changes, reduced reproductive capability, and altered behavior. Water parameters such as alkalinity and hardness are relatively stable, whereas others like pH, dissolved oxygen (DO), and temperature fluctuate regularly. Proper maintenance and monitoring of these water quality parameters in aquatic environments support fish health and enhance fish production. On the other hand, variability in dissolved ammonia, nitrites, and nutrients like nitrate significantly affects aquaculture production. It has also been observed that high feeding rates in aquafarms create eutrophic conditions in water bodies, leading to substantial algal blooms. These blooms are responsible for die-offs, and as a result, ammonia levels in the ponds rise rapidly. The environmental factors responsible for generating high ammoniacal concentrations may also lead to increased nitrite concentration in aquafarm. Both ammonia and nitrite are directly toxic or sublethal cultured aqua animals, leading to reduced resistance to diseases. In aquaculture system, ammonia is produced through the ammonification process, which occurs when organic matter is broken down by the microbial community. However, this decomposition also reduces dissolved oxygen levels in the system. Low dissolved oxygen surges the toxicity of ammonia to cultured animals. Ionized ammonia (NH4 +) and hydroxide ions occurs in equilibrium with unionized aqueous ammonia solution. The unionized form of ammonia (NH3) is toxic
