Title:
Characterization of Soybean Varieties for their Storage Potential by Using Accelerated Ageing
Abstract:

Soybean being a potential oil and protein crop for narrowing the oil and nutrition gap, occupies an important place in agricultural economy of India. The seed of soybean varieties PS 1347, PS 1042, PK 472 and PK 262, obtained from Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar were used for this study. Electrical conductivity increases while germination percent, seedling length and seedling vigour index-I decreases with an increase in accelerated aging periods in all varieties. The increase in electrical conductivity was minimum in PS 1042 and followed by PS 1347. Decrease in germination percent, seedling length and seedling vigour index-I was less in PS 1042 followed by PS 1042. Varieties PK 472 and PK 262 were found same in all studied parameters. This indicate that PS 1042 show better membrane integrity followed by PS 1347 thus have better storability than rest of the varieties.

Title:
Bio-priming with Arbuscular mycorrhizae for Addressing Soil Fertility with Special Reference to Phosphorus
Abstract:

Phosphorus (P) is an indispensable element in agriculture whose contribution is enormous in food production. The sources and availability of P has always been a great concern for humans because of the limited fossil reserves from where the mineral P fertilisers are processed, and alongside its low accessibility for plant uptake suggest the requirement of appropriate techniques which can enhance P use efficiency. Microorganisms being the integral component of P cycle can solve the P-related problems. Beneficial microbes like arbuscular mycorrhizae if used as seed treatment can yield strong and healthy plants and induce significant effects in rhizosphere soils. Thus, the concept of bio-priming are very important for carrying out the practices of sustainable agriculture.

Molecular Characterization of Pigment Producing Microbes Associated with Marine Sponges and their Microbial Assay
Abstract:

Marine sponges are animals grows under the sea level, contain abundant microbial communities, such as bacteria, archaea, microalgae, and fungi. Sponge associated microorganisms are an untapped source for pigments that can have wide range of applications in industries including food industry and textile industry. In the current study, Four species of sponges (Echinodictyum sp., Spongia sp., Halichondria panicea and Hippospongia lachne) from a depth of 5–10m were collected from Thiruchendur, South East coast of India and screened for pigment producing microbes. The Isolated microbes were characterized by phenotypic and molecular characterization. The pigments were extracted from the isolated microbes and are characterized by which they found to be carotenoid and chlorophyll. The antimicrobial activity of the pigment was analyzed by antibiotic sensitivity test, in which green pigment showed a broad spectrum of activity against Staphylococcus sp., viz., 22.5 mm, 25mm, 27mm, 30mm, and 32 mm respectively.

Title:
Agricultural Sustainability and Organic Farming
Abstract:

In the 20th century, great increases in productivity of Indian agriculture has encouraged higher and higher use of heavy farm equipment, fossil fuel, intensive tillage, high-yielding crop varieties, irrigation, extraneous inputs, and capital. In the process we incurred a great loss in the eco-system by indiscriminate use of fertilizers and other chemicals. Now, what we need is to save our natural resources – water, biodiversity and land. It may not be wondering if we assume that organic farming system may generate such situation to address both the challenges mentioned above. The present paper devoted an exploring effort to find out what performance is brought about by organic farming to address the problem of sustainability of crop productivity of different vegetable crops grown in West Bengal across the seasons. The sustainability measures viz. Sustainable Yield and Sustainable Value Indices (SYI and SVI) have been used for the purpose. The results showed that despite lower production in organic farms than inorganic farms, the sustainability of productivity occurred in organic farms were satisfactory. On the other hand, net return (value of products) from organic farms exhibited moderate sustainability. This was due to unorganized market for price premium of organic productions. Another reason of unattractive receipt from organic farms was higher cost of organic nutrients. The analysis concluded that availability of market and price premium with easy accessibility in sufficient quantity of organic manure may influence more sustainability in receipts towards vegetables cultivation in organic farms.

Title:
Production of Quality Jute Fibre through Accelerated Retting
Abstract:

Among the lignocellulosic fibres jute has been conspired as the golden fibre for its inherent colour and lustre. Jute is one of the cheapest natural fibers and is second only to cotton in amount produced and variety of uses. Jute fibres are composed primarily of cellulose and lignin. The fibres are separated from the woody core of the stem by steeping the bundles of the harvested and the defoliated plants in water of various sources. The process employs the joint action of microbes and moisture to dissolve the cellular tissues and pectin surrounding the bast fibre bundle facilitating fibre separation from the stem. Water retting produces more uniform and high quality fibre, but it requires both labour and capital. Large volume of clean water is needed for this purpose. Due to unavailability of sufficient water, quality of fibre produced becomes inferior. To avoid scarcity of water, the barks of decorticated jute plants are separated prior to retting in green condition. This is called ribbon retting. The process of retting is further accelerated by the application of a chemical accelerator formulated by National Institute of Research on Jute and Allied Fibre Technology, Kolkata. In this process the defoliated jute bundles (50kg) are immersed in a tank or confined water bodies with ratio of plant to water is 1:2. The bundles are stacked in reverse direction and at a place around 30-40 bundles can be placed. The retting in this process takes little longer, i.e., 10-12 days. Fibre quality in this process was found to enhance around two grades. This may bring economic benefit to the farmers to the tune of ` 500-600 per quintal of jute fibre yield.

Title:
Yield Maximization of Wheat (Triticum aestivum L.) Cultivars through Improved Water Management Strategy
Abstract:

A field experiment was carried out in alluvial agro-climate of zone of West Bengal during rabi, 2014-15 and 2015-16under the aegis of Bidhan Chandra Krishi Viswavidyalaya at AB block farm, Kalyani. The experimental work was conducted in split-plot design with three replications. Five different levels of irrigation based on crop growth stages viz., one irrigation at CRI stage (I1), two irrigation at CRI and tillering stage (I2), thee irrigations at CRI, tillering and jointing (I3), four irrigations at CRI, tillering, jointing and booting stage (I4), and five irrigations at CRI, tillering, jointing, booting and milking (I5) were randomly allotted to main-plots, while four timely sown advance wheat genotypes viz., DBW 39, PBW 343, K 0307 and HD 2967 were allocated randomly to sub-plots. More number of ear head/ m2 registered with the I4 and showed parity with the I5 and I3 and statistically better to other main plots treatments. Amongst various genotypes HD 2967 registered higher number of ear head/m2, and was significantly better to other set of treatments. Grain/ear head with various main plots treatments revealed that, I5 has more number compared to other allotted treatments, and showed parity with the I4 and I3 and better to all other treatments. Application of irrigation water at four different growths stages (CRI, tillering, jointing and booting stage (I4)), gave significantly more grain (35.65 q/ha) and straw (51.03 q/ha) yield compared to other allotted subplots treatments, except I5. Observation related to various genotypes revealed that, HD 2967 recorded significantly more grain (34.95 q/ha) and straw (61.05 q/ha) yield, and was at par only with K0307. Economics revealed that, more net return observed with I4 (` 47,087), but highest benefit cost ratio found with the I3 (2.06) and followed by I4 (2.02). Amongst various genotypes, highest net return observed with HD 2967, and this give equal B:C ratio with K0307(1.89). Despite higher yield and good return under five irrigations, the maximum benefit-cost ratio was recorded with thrice irrigated treatment indicating the cost incurred towards extra two irrigations did not result in proportionate yield increase. So it is concluded that under new alluvial zone of West Bengal cultivation of HD 2967 and K0307 with three to four irrigation found to be economical to the farmers.

Title:
Quality Requirement and Standards for Natural Resins and Gums
Abstract:

NRGs are metabolic by-products of plant tissues either in normal course or often as a result of either injury in the bark or wood or disease by insects. Most of the NRGs are plant origin and exudate product from the plant with the exception of lac resin which is secreted by lac insect mainly Kerria lacca. India has wide varieties of trees and plants which exudates Resins and Gums. The natural gums and resins are polymeric, biodegradable and non-toxic in nature. Being biologically originated, they have wide variations in their characteristics and properties. So, quality of the natural resins and gums are to be regulated for application in different sectors. Quality standards of natural resins and gums are to be set by according to national and international regulatory bodies. The quality standards of the natural resins and gums are very useful documents to find their in various novel application areas.

Title:
Approach for Enriched Nutrition through Pulse Consumption
Abstract:

Pulses are the richest source of plant proteins. They are also high in dietary fibres and complex carbohydrates leading to low GI (Glycemic index) than cereals and fibres that result in slow release of glucose in blood stream proving beneficial to diabetic people. Pulse help to lower cholesterol as their fibres constitute more amylose than amylopectin. They are natural sources of minerals which offer unique opportunity to combat against specific malnutrition known as hidden hunger. Being natural reservoir of antioxidants pulses tend to provide protective shield against oxidative stress which is closely linked to cancer and cardiovascular diseases. It is now being demonstrated that so called anti nutrients of pulse seeds are involved in health promoting processes and beneficial cellular effects which are gaining increasing attention for human health. Efforts should focus on developing attractive, convenient ready to eat and tasty pulse based food products contributing to the diversification of healthier and more nutritional diets.
