Title:
Brown Manuring, an Effective Technique for Yield Sustainability and Weed Management of Cereal Crops: A Review
Abstract:
The efficient nutrient management is essential to achieve crop yield sustainability. Integration of all possible sources of nutrients can only fulfill the requirement of crops and wherein yield sustainability can be ascertained. Organic manures can play in important role in this direction. But these manures are bulky in nature and low in nutrient content, hence the substitution is highly required. Green manure, another possible option of providing nutrients to crops from organic sources, but it has got some limitations as it is practiced in mainly rice crop that requires a period of about 45-60 days from seeding to decomposition with proper temperature and optimum moisture conditions after incorporation. The viable option left behind that is brown manuring as a tool for integrated nutrient management. Brown manuring is capable of supplying all nutrients to the crops which is also considered beneficial for weed management as well as improving soil properties.

Grading System of Ramie Fibre
Abstract:
Ramie is a highly versatile, white, lustrous and eco-friendly fibre with excellent properties1. In India, the cultivation as well as production of ramie is increasing because of its excellent strength, enhanced wet strength, lustre and microbial resistivity. At present there is no grading system in India. In view of the prospects of increased production and utilization of the fibre, a grading system for the decorticated fibres has been developed on the basis of fibre qualities. It is quite obvious that different varieties would differ in their properties and different application areas would demand different quality fibre. For this the fibre should be graded properly for utilization of the fibre in a better way. The fibres have been graded in to four grades viz. excellent, good, Average, Poor on a 100 point score card basis. The scores have been assigned on relative importance and weightage of the six fibre properties, viz. fibre length, strength, fineness, softness, colour and defects. The grading system will help the farmers, industry and other stakeholders in marketing and specific utilization of the fibre in diversified areas

Guiding Role to be played by the Indian Agricultural Extension Agencies to Bridge the Gaps in Fertilizer Application in India
Abstract:
Chemical fertilizers play a significant role in the development of agriculture sector and successful management of food security concerns in the country. Since the land resource is finite and there are increasing food requirements, the only way forward is to sustain increase in agricultural productivity at the same maintaining and improving the quality of soil. However the management of soil resources is facing several challenges in the forms of gaps in chemical fertilizer applications viz. wide variations in use of chemical fertilizers over the regions, a heavy skewness in favour of Nitrogenous fertilizer use and imbalanced and improper use of fertilizers. This type of challenges can be faced with proper Fertilizer Pricing Policy, Availability of credit facility, development of Knowledge-base of the Farmers, robust Fertilizer Policy, modern irrigation practices coupled with modern product lines of Indian fertilizer Industry. Indian Extension System with broader infrastructure, up-dating and re-orienting the extension workers with a multi-agency mode of work can play a crucial role in changing the irrigation and fertilizer application practices as being applied by the Indian farmers.

Title:
Root-exudates in Relation to Microbial Activity
Abstract:
Plant root exudate is a naturally occurring resource, constituting various chemical compounds which alter the micro-environment around the root and plays a significant role in plant-microbe interaction. The interaction may be positive or nagetive. Root exudates are often divided into two classes of compounds. Low-molecular weight compounds such as amino acids, organic acids, sugars, phenolics, and other secondary metabolites account for much of the diversity of root exudates, whereas high molecular weight exudates, such as mucilage (polysaccharides) and proteins, are less diverse but often compose a larger proportion of the root exudates by mass. The present paper tries to understand the nature of chemical composition of root exudate and type of interaction with microbe

Abstract:
A field experiment was carried out in alluvial agro-climate of zone of West Bengal during rabi, 2015-16 and 2016-17 under the aegis of Bidhan Chandra Krishi Viswavidyalaya at AB block farm, Kalyani. The experimental work was conducted in split-plot design with three replications. Four different date of sowing viz. 1st November, 15th November, 30th November and 15th December were randomly allotted to main-plots, while seven different nutrient management aspect mainly control, 50% RDF, 75% RDF, RDF, 50% RDF + FYM (@10 t/ha), 75% RDF + FYM(@10 t/ha) and RDF + FYM(@10 t/ha) were allocated randomly to sub-plots. More number of grain/spike found with the early date of planting (1st November) and was at par with the 15th November, and appreciably better to other main plots treatments. Amid a range of subplot treatments, highest grain/spike registered with the RDF and was at par with the RDF + FYM (@10 t/ha) and 75% RDF + FYM (@10 t/ha). Highest grain yield registered with the 15th November (37.01 q/ha) sowing, and was at par with the early sowing i.e. 1st November (35.07 q/ha). These treatment increases 72.25 and 61.91 % more grain yield over the extreme late sowing condition i.e. 15th December. Further, 75% RDF + FYM (@10 t/ha) gave more economic yield (37.47 q/ha), and was at par with the RDF + FYM (@10 t/ha), RDF and 50% RDF + FYM (@10 t/ha). More straw yield observed with the 15th November sowing, and was considerably superior to other main plot assignment. Amongst various nutrient management, maximum straw yield found with the 75% RDF + FYM (@10 t/ha), and was at par with all other treatments except control and 50 and 75% RDF. The 15th November sowing, gave more biological yield of wheat crop and drastically better to other main plots treatments. Moreover, with various subplot treatments, better this parameter found with the 75% RDF + FYM (@10 t/ha) and was at par with all other treatments, except control and 50 and 75% RDF application. Maximum, NPK uptake observed with early date of sowing i.e. 15th November compared to extreme late sowing condition i.e. 15th December. More primary nutrient removal observed with the 75% RDF + FYM (@10 t/ha) and was at par with RDF + FYM (@10 t/ha) and notably better to other subplot treatments. Amongst various nutrient management practices, more nutrient uptake found with the 75% RDF + FYM (@10 t/ha) and was at par with the full dose of RDF + FYM (@10 t/ha). Economics revealed that, more net return observed in 15th November planting (` 40, 453), with highest benefit cost ratio (2.04), and was followed by 1st November sowing. Amongst various nutrient management, highest net return (` 40,987) and benefit: cost ratio (2.13) observed with 75% RDF + FYM (@10 t/ha) and was followed by 50% RDF + FYM (@10 t/ha).

Distribution of Different Forms of Potassium in Some Coastal Soils of West Bengal
Abstract:
The research work with a view to evaluate the status, availability, fixation, releasing and supplying behaviour of potassium for a meaningful K-fertilizer management strategy for sustainable crop production in the coastal soils of West Bengal. Forty surface (0-15 cm) soil samples representing the coastal soils of West Bengal were used for assessing the important physical and physicochemical properties and distribution of different forms of potassium. Total K and lattice K content of the soils were high ranging between 1.0 to 2.74 and 0.93 to 2.60%, respectively. Non-exchangeable, available, exchangeable and water soluble K contents of the soils varied from 534 to 1050, 68.81 to 284.77, 58.65 to 232.50 and 10.16 to 52.27 mg/kg contributing 3.84 to 6.32, 0.53 to 1.23, 0.45 to 1.02 and 0.08 to 0.22% towards total K, respectively. The overall soils were high in available, non-exchangeable and mineral K status. Based on the district wise average values of the different forms of K, the soils were in the order: Medinipur East > North 24 Parganas> South 24 Parganas. Different forms of soil K had highly significant positive correlation with pH and EC. Non-exchangeable K was significantly and positively correlated with organic carbon and CEC. Available K, exchangeable K and water soluble K had significant negative correlation with sand. All the
forms of soil potassium were interrelated, indicating the existence of a dynamic equilibrium among them

Title:
Evaluation of Chemical and Biological Indices for Carbon and Nitrogen Mineralization of Various Organic Matters Used in Tea Garden
Abstract:
The objective of this study was to evaluate the performance of chemical and biological indices to predict carbon and net nitrogen mineralization from a range of organic amendments that differed in their total carbon and nitrogen and the carbon quality. Three decomposed materials i.e. vermi compost (VC), farm yard manure (FYM), poultry manure (PM) and four un-decomposed materials i.e. raw cow dung (RCD), fish meal (FM), tannery waste (TW) and mustard cake (MC) were used for the experiment. Carbon mineralization was determined using alkali traps. Aerobic nitrogen mineralization was estimated using incubation and leaching method, whereas, anaerobic N-mineralization was done under waterlogged condition at 40oC. It was observed that water soluble organic carbon (WSOC) had significant correlation with C-mineralization (r=0.885**) and net aerobic N-mineralization (r=0.805*). Linear regression analysis also exhibited that WSOC had a very high linear relation with C-mineralization (r2=0.7835) and net N-mineralization (r2=0.649). Biological parameter i.e. 7 days anaerobic N-mineralization (ANI7) at high temperature exhibited significant correlation with C-mineralization (r=0.960**) and net aerobic nitrogen mineralization (r=0.855*). Net N-mineralization (aerobic) when regressed against anaerobic nitrogen index i.e. ANI-7, ANI-14 and ANI-21, R2 value of 0.733, 0.945 and 0.960 were found, respectively, indicating that anaerobic nitrogen mineralization index can be a useful tool for predicting nitrogen mineralizing capacity of various organic matters.

Title:
Impact of Agricultural Inputs on Soil and Strategic Management of Soil Health in India
Abstract:
Agricultural inputs paved the way towards green revolution in India. It was possible to feed its burgeoning population through the exposure of agricultural inputs which has retained its footprint in the evil sides. Its impact was extended from air to water, from soil to toil. The exigency of agricultural inputs is unavoidable and without the inputs todays agriculture cannot sustain. The only way to prolong the sustenance is through the strategic management approach. However, the strategic management approach has different layers and the systemic layer management could expose the opportunity towards the scientific management of soil health. Many countries in the world has already been rationalized the soil health management approach and accomplished the major objective through the basic commands on their input management. The increase in production of NP/NPK complex fertilizers contributed to higher production of fertilizer nutrients though it was not properly impacted towards the yield potentiality of Indian agriculture. The harmony in the nature can only be achieved through the skillful and scientific management strategy of inputs and soil which is need of the hour for further green revolution
