India will need to produce 30% more wheat by 2050, and these gains must principally come from intensification in eastern India where low productivity is common. Through a dense network of on-farm surveys for the rice–wheat system in this region, we show that contemporary wheat sowing dates have a central influence on achieved and attainable yields, superseding all other crop management, soil and varietal factors. We estimate that untapped wheat production potential will increase by 69% with achievable adjustments to wheat sowing dates without incurring undesirable trade-offs with rice productivity, irrigation requirements or profitability. Our findings also indicate that transformative gains in wheat yields are only possible in eastern India if rice and wheat are managed as a coupled system. Steps taken to ‘keep time’ through better management of the annual cropping calendar will pay dividends for food security, profitability and climate resilience now and as a foundation for adaptation to progressive climate change.
An effort has been made to study the effect of climate change on crop residues and need of crop residue management in present environmental condition. Crop residue management as an important practiced in the rice–wheat cropping system. In present condition, cropping season is shifted according to changing rainfall pattern. In case of wheat and rice-based cropping system, there is a chance of crop loss due to occurrence of rainfall at harvesting stage so, to cope with that situation combine harvesters become more popularize among farmers because of effective harvesting in less time, less effort and minimum labour cost. But it lefts a huge amount of loose straw in their field and farmers face difficulties in the disposal of huge straw in the field in short time has compelled to go for crop residue burning to save time as well labour. Farmers can use that residues in vermi-composting, can be fed to animals after urea treatment etc. without burning. In recent year 30-40% maize crop have been damaged due to hailstorm at its grain filling stage so these residues can be used in making silage. Removal of straw or stover can result in significant loss of soil organic carbon (SOC). If they are used as bedding for livestock, then much of the carbon may be returned to the soil as manure (Lal et al., 1998). When crop-residue is incorporated into soil, the soil’s physical properties and its water-holding capacity are enhanced. Unlike in earlier conservation farming systems wherein retained stubble was mulched and slashed, now it is mostly burned by the farmers. Vermicomposting, waste decomposer, Green Manuring, use of zero tillage machine, silage making and urea treated straw are the best option to crop residue management. The study aimed to examine the present status of crop residue management of major crops and its impact on farmers’ livelihood covering eleven blocks in Banka district of Bihar.
The domestication of animals was part of a major transformation in the way of life of an increasing number of human societies with deep social and spiritual changes. In the present study, we report about utility of Nilgai and the values of its products and how it can add variety in our diet. Domestication of Nilgai may prove as an outstanding diet (veal and juveniles) for human and domesticated carnivores it may be the most important achievements that man-made in his cultural history. It is very useful and has many kinds of beneficial mutualism with man exists. We also prerequisite to reconnoiter biological functions, importance, and distinctiveness of products viz milk, meat, leather and body parts such as skin, teeth, nail and other product in addition to transportation and export, because of their size and powerful appearance. The meat of Nilgai is said to be lighter and milder flavored than that of blackbuck meat. A domesticated animal such as livestock plays a vital role in diversified farming systems because food and recycling of nutrients through the farm are well proven. Nilgai appears to have different color which occurs during the developmental stage, like a fawn, juveniles and adults. Few Nilgai showed some docility behavior in nature subsequently that sighs of taming towards domestication. Nilgai may prove a higher status than other domestic animals when it comes to success in domestication. The Nilgai dwelling near the human habitation in proximity to a close distance in anthropogenic and share with its habitat and graze food and fodders with domestic herbivore mammals like goat, buffalos’ and cow in the periphery of the village’s areas. The domestication of Nilgai corresponds to a pivotal change in history not only of humanity but also of the biosphere.
Turmeric(Curcuma longa) is one of the important spice crops grown for fresh and processing purpose all over the India due to its wider adaptability under various agroclimatic conditions, which plays a major role in supplementing the income of small and marginal farmer of the Bhagalpur district of Bihar state. The present study was carried out atGoradih&Pirpainti block of Bhagalpur district during kharif 2017-18 and 2018-19. Varietal replacement through Farmer FIRST Project were conducted on turmeric by the active participation of the farmers with the objective of improved technologies of turmeric production potential. The improved technologies consist improved variety (Rajendra Sonia), balanced fertilizers (Soil test based) application and integrated pest and disease management, etc. The development of the agriculture is primarily depends on the application of the scientific technologies by making the best use of available resources. One of the major constraints of traditional turmeric farming is low productivity because of non-adoption of advanced technologies like improved varieties. To increase the production, productivity and quality of agricultural produce, varietal replacement are being conducted at various farmer's field. All the recommended practices were provided to the selected farmers. The data related to the cost of cultivation, production, productivity, gross return and net return were collected as per schedule and analysed. Result of the present study revealed the higher average yield in the varietal replacement demonstration was recorded (254.61 q/ha) as compared to farmers practice (125.20 q/ha) traditional adopted by the farmers. The percentage increase in the yield over farmer's 103.35 was recorded. The technology gap and extension gap were computed 145.39and 129.40q/ha respectively, along with 36.34 percent of technology index. The varietal replacement demonstration field gave higher average net return Rs. 653001.00 and B:C ratio is 1: 2.74. The result of the study indicated the gap existed in the potential yield and demonstration yield is due to soil fertility and weather conditions. Present result clearly show that the yield and economics of turmeric can be boost up by adopting recommended technologies. K e y w o r d sspice crops agro-climatic soil fertility weather conditions
