Effect of Nitrogen and Phosphorus Management on Growth and Yield of Foxtail Millet [Setaria italica L.] During Summer Season in Odisha, India

摘要

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 phosphorous viz. 0, 20, 40 kg P ha-1. The experiment was conducted in split plot design with nitrogen levels as main- plot and phosphorous 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 othertreatments. 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 Nand 20 kg P2O5 ha-1.
