Performance of Rice Under Crop Residue Incorporation and Different Nitrogen Management Practices

Abstract

Field experiments conducted for in consecutive years 2002-2003 and 2003-2004 revealed that by raising a reasonably short duration leguminous crop (either a pulse or vegetable depending on farming situation) preceding to rice and incorporation of the crop residues after picking the economic yield and supply of 100 % recommended dose of nitrogen through fertilizer was the best nitrogen management of rice with higher productivity and economic returns. Incorporation of field bean crop residues (C3) was superior to other crop residue incorporation with regard to yield attributes and yield. The highest gross returns and net returns as well as benefit-cost ratio were also recorded with the incorporation of crop residues of fieldbean (C3 ). Supply of 100 % N through fertilizer to rice (N2) was superior to any other nitrogen management practices, with regard to yield attributes and grain yield. The highest gross returns, net returns and benefit-cost ratio were recorded with application of 100 % nitrogen through fertilizer (N2 ) followed by supply of 50 % nitrogen each through fertilizer and FYM (N3)
