The country is at long last becoming sensitive to the serious consequences of the growing rural-urban divide in terms of investment, infrastructure and opportunities for income and employment. The rural-urban divide also leads to an expanding rich-poor divide. Since crop and animal husbandry, fisheries, forestry, and agro-processing are the main sources of rural livelihoods, the current agrarian crisis is adding to the problems of hunger, poverty and unemployment. According to the Union Planning Commission, we are off-track in achieving most of the UN Millennium Development Goals. A major cause for the growing rich-poor divide both between and within nations is unequal access to modern technology. Technology helps to achieve a paradigm shift from unskilled to skilled work and thereby move large numbers of the rural poor from the primary to the secondary and tertiary sectors of economic activity. If technology has been a major factor in promoting economic and social divides in the past, the challenge now lies in enlisting technology as an ally in the movement for economic, gender and social equity.

Mitochondria are key energy generators in most eukaryotic cells. In recent years a number of mitochondrial genomes have been completely sequenced, contributing to the knowledge of molecular features related to function and evolution of this peculiar genome (Boore, 1999). The pathways of mitochondrial DNA evolution are obscured by their extraordinary size. Gene content, gene rearrangement and mode of expression are the characteristics of mitochondrial genomes. The mitochondrial genomes from eukaryotes reveal large size differences between animal, fungal and plant species. The average size of animal mtDNA is ~ 16 kb (Boore, 1999), whereas plant mtDNAs range from 200 to 2500 kb (Palmer, 1990). The size of fungal mtDNA’s range from 19 kb to 176 kb (Hudspeth, 1995).The mtDNA genome has a limited number of protein coding genes such as NADH ubiquinone oxidoreductase (ND2 to ND5), cytochrome c oxidase (COX), succinate dehydrogenease (SDH), ATP synthase (ATP6), cytochrome (CYTB), etc. Among non-coding genes only rRNA and tRNA genes are found.Ribosomal RNA (rRNA) is a component of the ribosomes, the protein synthetic factories in the cell. rRNA molecules are extremely abundant. They make up at least 80% of the RNA molecules found in a typical eukaryotic cell. Synthesis of the three nucleolar rRNA molecules is unusual as they are made on one primary transcript that is chopped up into three mature rRNA molecules.

6.1 Preparing for Negotiation

Introduction

When people hear the word Negotiation, they picture board meetings, lawsuits and favorable deal-makers sipping tea in a conference room. They are pictured being dressed in their expensive suits and handing dossiers to each other. In reality, we negotiate all the time. If we have to sight a negotiation, all you have to do is lift the window-pane and look out. For instance, have you ever decided where to dine with friends, or decided upon a leave and talked it out with your supervisor, or argued with your senior for a hike? These are all some common examples in our daily routine.

Bael [Aegle marmelos (L) Correa.], a native fruit of religious importance, is well known to the Indian people for its nutritional and medicinal values. Leaves are used as sacred offering to ‘Lord Shiva’. All parts of plant viz., leaves, roots, bark, fruits, seeds etc. are used in preparation of various Ayurvedic medicines. Bael fruit is rich in protein, fat, minerals (Ca and Fe) and vitamins (riboflavin, β carotene and Vitamin C). Fruits are used to improve the digestive system and to cure stomach diseases. Fruits can be processed into various beverages and preserves (Jauhari and Singh, 1971). In spite of its Indian origin and high medicinal and nutritional values, well organized orcharding of bael is not commonly seen in the country. It is mainly found in wild and semi-wild condition throughout the India. Besides, it is also grown in the homestead gardens, backyards, religious places and farmer’s fields (Misra and Uniyal, 2013).

ABSTRACT

Astudy was undertaken at Department of Soil Science & Agrl. Chemistry, College of Horticulture, Vellanikkara to standardize different amelioration techniques to prepare enriched coirpith compost. Twelve treatments were tried using different combinations of coirpith, Pleurotus spp., Schizophyllus spp., urea, rock phosphate, cowdung slurry, mushroom waste, goat manure, glyricidia and water hyacinth. The results of the various enrichment techniques revealed that the temperature in the compost in general, increased to a peak value of 47oC on the 22nd day of composting and later decreased to a stabilized value. The observed temperature of 40-50 °C found during the thermophilic stage is essential for the rapid degradation of lignocellulose, as the thermophilic microfungi and actinomycetes involved in this process thrive at that temperature. Though the pH show a hike at the initial stage of composting, it decreased and stabilized at the later stage of composting which is conducive for growth and proliferation of microbes. The treatment coirpith with Pleurotus spp., glyricidia +20% cowdung slurry and goat manure was found to be ideal for compost preparation.

Introduction

The most common method of bacterial transformation utilizes high levels of calcium chloride to facilitate the entry of plasmid DNA vectors into E.coli in conjunction with structural alteration of the bacterial cell wall. In general, there are three basic steps in the introduction of plasmid DNA unto cells.

1. Preparation of “competent” cells to enable cells to accept DNA.
2. Transformation of these competent cells, and
3. Selection of transformants.

Most E.coli strains exhibit transformation efficiency (measured as transformants per microgram plasmid DNA) in the range of 10⁵ to 10⁸.

The factors influencing this efficiency depends upon the condition that render cells competent.

Raw milk is an emulsion. It is a mixture of milkfat globules, Solid Not Fat (SNF) and water. Over time, milkfat globule separate out from milk serum and comes to the surface of milk as a layer of cream due to the low density of milkfat or due to heating of milk. When milk is heated rapidly and continuously, some of the water in it evaporates from the surface. This exposes proteins and fat molecules, which bind and dry out and forms a skin like film on the surface. 

The earliest Brassica planted in North America was Chinese cabbage, also known as celery cabbage and napa. It is becoming increasingly popular in western kitchens. When eaten fresh, the huge savoyed leaves with thick succulent midribs have a sweet flavour and crisp texture. The Pekinensis Group and the Chinensis Group are two cultivar groups of leaf vegetables frequently used in Chinese cuisine. These vegetables are turnip cultivars or subspecies that belong to the same genus as cabbage, broccoli, and cauliflower, among other Western mainstays.

Botany & taxonomy: Brassica rapa, one of two commonly cultivated mustard family (Brassicaceae) members that are variants of Chinese cabbage. Pak Choy is a type of Chinese cabbage (Brassica rapa var. chinensis). Celery cabbage is another name for Napa cabbage.

Introduction

Women make essential contributions to the agricultural and rural economies in all developing countries. Their roles vary considerably between and within regions and are changing rapidly in many parts of the world, where economic and social forces are transforming the agricultural sector. Agriculture needs manpower, if the manpower split into gender wise, amazing fact is that the women contribution is greater or equal to men (Chauhan, 2011).That is reason that right from the day the country become independent, it has been trying hard for rural development.

According to the Penguin Atlas of Women in the World, women make up 40 per cent of the agricultural labour force in most parts of the world, while in developing countries they make up 67 per cent of the agricultural workforce (Singh, 2008). Therefore, strengthening and expanding women’s roles and opportunities in agriculture promotes sustainable economic development. Gender inequalities are a measurable and significant limit on agricultural productivity and efficiency, undermining rural economic development. India has paved the way to development by increasing its trade and growth in Agriculture sector. To review the agriculture scenario of our country, it depicted that there is need to pay sincere attention towards the human resource development (men and women together) because modernizing agriculture needs skill and efficient work forced. Farm business has become a family enterprise in India, where both men and women take part evenly. It is well known fact that the success of rural development process largely depends on the participation of people at large, irrespective of sex. The problems of involving women’s participation in the development process are now catching the attention of planners and policy maker because of increasing imbalances generated out of development process. Now days, rural women play a vital role in domestic and socio-economic life of the society and therefore, national development is not possible without developing this important and substantial section of our society (Okafor, 2008).

Our nation happens to be the largest producer of goat milk globally and it is high time that we use this to our advantage. India happens to be one of the fastest growing economies of the world and the IMF projects our GDP is set to rise at a healthy rate of 5.9 % in 2023, the highest among all other economies.

Goat Production in Field Conditions

We are an agro-based nation with 70% of our population residing in rural areas. As we deliberate today on the best possible ways to facilitate natural goat farming, we have to remember that such traditional agrarian practices is the essence of our Indian ethos, from ancient times. Such wisdom has been passed on for generations and it is great to witness that the world is waking up to the benefits of the natural versus the synthetic be it in clothing or food or lifestyle in general.

Lake Effect : The effect of any lake in modifying the weather and climate along its shore and inland which depends on the size of the lake. In some areas such as the North American Great Lakes, lake effect refers to snowfall generated by the lake on the downwind shore.

Lake Effect Snowfall : Snowfalls along the lee shore of a lake or downwind some distance from the shore caused by the modification of cold, subfreezing air by the relatively warmer lake water. The intensity of the lake-effect snowfall depends upon several factors : the temperature contrast between the lake surface and the air passing over it, the over-water distance the air has traversed (the fetch), and the regional weather situation. 

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such communition is an important unit operation in many processes. There are manydifferent types of mills and manytypes of materials processed in them. Historically, mills were powered by hand (e.g., via hand cranks) working animals (horsemill), wind (wind mill) or water (watermill). Today they are usually powered by electricity and are controlled by computer (automatic mills).

The grinding of solid matters occurs under exposure of mechanical forces that trench the structure by overcoming of the interior bonding forces. After the grinding, thestate ofthesolid is changed:thegrain size, thegrain size disposition and the grain shape.

Milling also refers to the process of breaking down, separating, sizing, or classifyingaggregatematerial. For instance rock crushingor grindingto produce uniform aggregate size for construction purposes, or separation of rock, soil or aggregatematerialforthe purposesofstructural fillor land reclamationactivities. Aggregate milling processes are also used to remove or separate contamination or moisture from aggregate or soil and to produce “dry fills” prior to transport or structuralfilling.

Grinding may serve the following purposes in engineering: • Increase of the surface area of a solid

• Manufacturing of a solid with a desired grain size

Packaging is an important consideration in vegetable and fruit market. The use of properly designed containers for transporting and marketing of vegetables is significantly reduce losses and maintain their freshness succulence and quality for longer period. Packaging also provides protection from mechanical damage and undesirable physiological changes and pathological deterioration during storage, transportation and marketing.

Many vegetables are transported in gunny bags and bamboo baskets. Packaging material such as polythene films, paper boars, and boxes lived with polythene and other materials can effectively prolong the shelf life of vegetables. By using plastic films vegetables can be protected from dry air. Polythene packaging provides modified atmosphere and consequently reduces decay, softening, and loss of solids. The thickness and permeability to CO₂, O₂ and water vapour of films needs to be standardized for each vegetable.

Introduction

Jack fruit is indigenous to India and is commonly grown in Sri Lanka, Malaysia, Brazil, Jamaica, Myanmar, Singapore, and India. In India, it grows in a wild and semi-wild state in Kerala, Assam, W.B, Tripura, Bihar, U.P. and Western Ghats. Jackfruit is a common and popular fruit crop in the low land tropics of the eastern and southern parts of India. It is the largest edible fruit (20–40 kg). In Sri Lanka, a fruit of about 120 kg was harvested and created the world record. The fruit is also called “poor man’s fruit” in the eastern and southern parts. In the Tamil literature, Jack has been given the important second position of the significant ‘three fruits’, viz., ‘Mukkani’. It is mainly distributed in the tropical humid belt. In India, Assam, Bihar, Kerala and Tamil Nadu are the main jackfruit growing states. In Tamil Nadu, the lower Palani hills of Dindigul Anna district and Panruti of South Arcot Vallalar district are known for the best quality jack fruit. India is considered to be the native home of jacks.

Elephant foot yam, also known as suran or jimmikand, is gaining popularity due to its high yield potential and culinary qualities. It is grown in Andhra Pradesh, Bihar, Gujarat, Kerala, and Maharashtra in India, as well as in the north-eastern states of Odisha, Tamilnadu, Uttar Pradesh, and West Bengal. This crop is being embraced for commercial production in northern and eastern India, thanks to the advent of a high yielding, non-acrid variety. Elephant foot yam has an output potential of 50-60 tonnes per hectare. Elephant foot yam is a tropical tuber crop that has been grown for generations in tropical Asia. It is gathered for its edible corms, tubers, and smooth petioles, which all contain important minerals.

Yersinia species are non-lactose fermenters and, with the exception of Y. pestis are motile. Although there are more than 10 Yersinia species, only Y. pestis, Y. enterocolitica and Y. pseudotuberculosis are pathogenic for animals and man. Yersinia ruckeri causes perioral haemorrhagic inflammation in some species of fish. Growth of yersiniae tends to be less rapid than other members of the
Enferobacteriaceae. They characteristically demonstrate bipolar staining in Giemsa-stained smears from animal tissues
Natural Habitat
Y. pestis, the cause of bubonic plague in man and a sylvatic cycle in animals, is transmitted mainly by fleas from tolerant rodents. Human infections through cuts, bites, scratches and aerosols can also occur. Cats are susceptible to Y.pestis and naturally infected cats can pose a health hazard for humans in endemic areas. Y. pseudotuberculosis persists in wild rodents and birds as well as in the environment. The intestinal tract of wild and domestic animals appears to be the reservoir for Y. enterocolitica. Pigs, particularly, are carriers of Y. enterocolitica strains pathogenic for humans.
Isolation
Yersinia species grow on nutrient, blood and MacConkey agars but the colonies, after 24 hours incubation, tend to be smaller than those of the other members of the Enterobacteriaceae. Y. pestis grows poorly on agars containing desoxycholate whereas Y. enterocolitica and Y. pseudotuberculosis grow well on these media. Yersinia selective medium (CIN agar) containing the antibiotic supplement cefsulodin (15mg/litre), irgasin (4 mg/litre) and novobiocin (2.5 mg/litre) is designed for the isolation of Y. enrerocolitica from faeces.

their starchy seeds, which are scientifically referred to as caryopsis. These plants, along with cereal fodders and grasses, typically exhibit a determinate growth pattern and the quality of their herbage tends to decline following the flowering stage.
Kharif Crop (Hot and Wet Season)
1. Bajra /Pearl millet (Pennisetum americanum/typhoides): Bajra, also known as pearl millet, ranks as the fourth most significant cereal crop, following rice, wheat and sorghum. This crop is primarily cultivated for both grain production and as fodder. It thrives predominantly in the arid and semi-arid regions of India, where it is typically grown as a rain-fed crop during the Kharif season, specifically in the months of June and July. Bajra is characterized by its rapid growth and resistance to diseases, making it an ideal fodder option; however, it is not well-suited for areas with high rainfall. Harvesting and yield: The average yield of green fodder from bajra is approximately 300-400 quintals per hectare. When harvested for grain, the kadbi production can reach 50-60 quintals per hectare. For optimal fodder production, harvesting should occur before the flowering stage or at the 50% flowering mark to ensure quality feed for livestock. Nutritive value: At the flowering stage, the CP content is around 4.50%. The initial cutting is recommended 50-80 days post-sowing, with subsequent cuts occurring every 35-40 days, maintaining a cutting height of 15 cm above ground to promote re-growth. A total of two cuts can be achieved for enhanced yield. Bajra serves as a non-maintenance type of fodder. It is typically harvested and provided to livestock as green fodder, with the potential for conversion into hay or silage. However, the straw produced from bajra is of inferior quality, containing only 4-5% CP and 1% DCP. Additionally, this fodder is high in oxalates, necessitating supplementation with calcium sources such as DCP or calcium-rich leguminous fodder. The composition of bajra includes 8.52% CP, 1.76% EE, 54.91% NFE, 25.01% CF, 9.80% TA,
0.55% Ca and 0.27% P on DMB. The DM content is 22%, with 13% TDN and 0.90% DCP on as-fed basis. When expressed on DMB, the DCP and TDN values are 3.04% and 48.47%, respectively.

As globalization evolves, including free trade liberalization and the expansion of rural agribusiness, smallholders face challenges in adapting to the changing market economy. Population growth and land inheritance laws have led to the subdivision and fragmentation of farmland. In countries like India, smallholders risk marginalization as larger agricultural enterprises increasingly dominate profitable agribusiness.
Recent global trends emphasize environmentally sound practices-balancing ecological and economic concerns and sustainability, which integrates social, environmental and long-term economic considerations. These principles, along with health and environmental regulations, are driving the expansion of contractual farming relationships (Rehber, 2019). Globalisation and market liberalisation in developing countries have transformed agricultural markets, creating new opportunities for high-value products (Wigboldus, 2018). Consequently, migration to urban areas is widespread. According to the Periodic Labour Survey Report (July 2020 - June 2021), the primary reasons for male labour migration are “search for employment or better employment (22.8%)” and “to take up offered employment opportunities or be close to their workplace (20.1%)”. Efforts to curb this migration focus on promoting income-generating activities for smallholders. However, these initiatives have largely failed due to a lack of market linkages-both backward and forwardand reliable, cost-effective inputs, such as extension services, mechanization, quality seeds, fertilizers, credit and access to profitable markets. Evidence suggests that well-organized contract farming can establish such linkages, offering smallholders an affordable pathway to operate commercially. Notably, contract farming can ensure a dependable supply of agricultural products, both in quality and quantity.
Since its inception, contract farming has demonstrated its potential to support smallholder farmers. Historical evidence shows the opportunities of contract farming from ancient Greece, China and to modern United States. The foundation of such arrangements in different countries is a commitment by smallholder farmers to provide a specific community with certain quantity and quality standards set by the purchaser and a commitment by the company to

After the Green Revolution, it is now time for an Ever-Green Revolution based on Eco Agriculture or Agroecology. In 2018, the FAO described Agroecology/Eco Agriculture as a means to transform food and agriculture systems by addressing root causes and emphasizing the improvement of efficiency in resource use, conserving, protecting and improving livelihoods, promoting equality and well-being and enhancing the resilience of people, communities and ecosystems. A timely transition to a sustainable eco-agriculture approach is essential to protect food security, the well-being of people and farmers prosperity. Eco Agriculture is a broad term that can inclusively refer to agroecology, regenerative, organic, natural, jaivik, etc, and is increasingly being recognized as the way to help save the planet. While discussing this with Prof Swaminathan and the ICFA team, the idea of a Working Group emerged. When I was requested to form the Eco Agri Working Group through ICFA, I consulted with different sectors and tried to determine the “why” and “how” of the impending Eco Agri Revolution.
WHY
The past sixty years led to Green Revolution and alongwith that ‘success’ several adverse impacts and the changing global situation as noted in Table – 1 are the reasons for the need for an Evergreen Revolution based on Eco Agriculture

In the context of molecular biology, a consensus sequence is the minimum nucleotide sequence that shows the characteristics common to most members of the family among a set of related genetic sequences.It serves in representing the results of a multiple sequence alignment, where related sequences are compared to each other, and similar functional sequence motifs are found. It also shows conserved/variable residues. It is found several times in the genome and is thought to play the same role in its different locations. For example, many transcription factors recognize particular consensus sequences in the promoters of the genes they regulate. In the same way restriction enzymes usually have palindromic consensus sequences, usually corresponding to the site where they cut the DNA. Transposons act in much the same manner in their identification of target sequences for transposition. Splice sites, i.e. those sequences immediately surrounding the exon-intron boundaries, can also be considered as consensus sequences. Defining a consensus DNA binding site by examining consensus sequences is a key work carried out by biologists (Harley et al., 1994). Rareness or anomaly detection followed by in depth analyses in such sequences may reveal significant information regarding the structural, functional and biochemical mechanisms of the genes which are of much importance to biologists.
