Abstract: A field experiment was conducted during the kharif and rabi season of 2016-17 and 2017-18 in the Research farm of College of Agriculture, Central Agricultural University, Imphal in order to study the residual effect of different weed and nutrient management on the productivity and economics of zero tilled rapeseed in rice-rapeseed cropping sequence. The experiment was laid out in factorial randomized block design (FRBD) replicated thrice. The pooled data revealed that among the weed management practices, application of Pyrazosulfuron ethyl (PSE) + Hand weeding (HW) at 40 DAS (W2) and Pyrazosulfuron ethyl (PSE) + Mechanical weeding (MW) at 40 DAS (W3) in preceding kharif rice gave the highest growth and yield of rapeseed. Among the nutrient management practices, better growth and yield of rapeseed were recorded with the application of 50% RDF+ 6t FYM (N1) and 50% RDF+ Azolla (dual crop)@10t/ha + 3t FYM (N2). Maximum gross returns, net returns and B:C ratio were also obtained with the above weed and nutrient management practices.
