Abstract
A field experiment was conducted during summer (Feb-May) of 2018 at Bagusala Research Farm, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Parlakhemundi, Odisha on sandy loam soil. Treatments consisted of four nitrogen levels-0, 20, 40 and 60 kg N ha−1 and three levels of phosphorus viz. 0, 20, 40 kg P ha−1. The experiment was conducted in split plot design with nitrogen levels as main-plot and phosphorus levels as sub-plot. Observations on plant height, dry matter, yield attributes and grain and straw yield, cost of cultivation, gross and net returns and B: C ratio were recorded. Application of 60 kg N ha−1 and 40 kg P2O5 ha−1 resulted in highest growth, grain and straw yield as compared to other treatments. The grain (1546 kg ha−1) and straw yield (2277 kg ha−1) was significantly higher with application of 60 kg N ha−1 over that of 0, 20 and 40 kg N ha−1. The maximum gross and net returns and B: C ratio were recorded with application of 60 kg N and 20 kg P2O5 ha−1.
