Bihar Agricultural University, Sabour

Bihar Agricultural University, Sabour established on 5th August, 2010 is a basic and strategic institution supporting more than 500 researchers and educationist towards imparting education at graduate and post graduate level, conducting basic, strategic, applied and adaptive research activities, ensuring effective transfer of technologies and capacity building of farmers and extension personnel. The university has 6 colleges (5 Agriculture and 1 Horticulture) and 12 research stations spread in 3 agro-ecological zones of Bihar. The University also has 21 KVKS established in 20 of the 25 districts falling under the jurisdiction of the University. The degree programmes of the university and its colleges have been accredited by ICAR in 2015-16. The university is also an ISO 9000:2008 certified organisation with International standard operating protocols for maintaining highest standards in teaching, research, extension and training.VisionThe Bihar Agricultural University was established with the objective of improving quality of life of people of state especially famers constituting more than two third of the population. Having set ultimate goal of benefitting society at large, the university intends to achieve it by imparting word-class need based agricultural education, research, extension and public service.

    Effect of tillage and crop establishment practices on productivity, profitability and sustainability of maize based cropping systems
    (Department of Agronomy, BAU, Sabour, 2019-05-03) Mishra, Sunil Kumar; Pathak, S. K.
    A field experiment was conducted on Bihar Agricultural College Research Farm, Sabour, Bhagalpur during the kharif and rabi seasons of 2012-13 and 2013-14. The experiment was laid out in a split plot design with three replications. The treatments comprised of three tillage systems viz.conventional tillage, zero tillage and permanent raised bed system in the main plots and six cropping systems viz.maize+soybean-wheat, maize-wheat, maize-maize, maize-rapeseed, maize-chickpea and soybean-maize in sub plots. The soil of experimental plots was silty loam in texture, neutral in reaction, low in organic carbon & nitrogen, medium in available phosphate and potash. Field observations were taken in all crops viz. kharif maize, soybean, rabi maize, wheat, rapeseed and chickpea in two heads, growth and yield and yield attributes.The observations with similar dimensions were pooled for analysis over the environments of the two cropping seasons. However, the data with varying dimensions over various cropping systems has been interpreted from the mean of two years. All growth parameters of kharif and rabi crops viz. plant height, dry matter accumulation, leaf area index (LAI) and crop growth rate (CGR) were affected by tillage. Similarly, yield attributes of kharif maize, soybean, rabi maize, wheat, rapeseed and chickpea were affected by tillage. Total number of weed flora and weed dry matter was found significantly lower in permanent raised bed and zero tillage over conventional tillage at both 30 and 60 DAS. Significantly higher maize equivalent yield, gross returns, net returns and B:C ratio was recorded in zero tillage and permanent raised bed in comparison to conventional tillage. Among cropping systems tested,maize-maize cropping system recorded significantly highest gross return and net return while B: C ratio was recorded to be maximum in maize-chickpea cropping system. Significantly highest system energy output, net energy and energy use efficiency were found in permanent raised bed and zero tillage than conventional tillage. Maximum total nutrient uptake of N, P and K was found in, which was significantly higher over the conventional tillage. Among cropping systems, the nutrient uptake was found highest in maize-maize system. So far as fertility status of soil was concerned, there was more build-up of available soil N, P and K in permanent raised bed and zero tillage than conventional tillage. However in cropping systems, maize- chickpea cropping system noted maximum build-up of available N, P and K. On the basis of results of net return, B:C ratio and energy use efficiency obtained during two years of experimentation it can be concluded that, among different tillage systems, permanent raised bed and zero tillage may be advocated over conventional tillage whereas among cropping systems, maize-maize system for maximum system productivity (MEY) & net returnsand maize - chickpea cropping system for maximum B:C ratio may be preferred. With respect to soil fertility, permanent raised bed and zero tillage may be better option over conventional tillage.
