Effect of Different Tillage and Nutrient Management Practices on Yield Attributes and Economics of Direct Seeded Rice

An experiment was conducted in an ongoing trial at the Agronomical Research Farm (plot no. 5) of Tirhut College Agriculture, Dholi (RPCAU, Pusa) during Kharif 2019. The laid out ‘split-plot design’ with tillage practices under main plot treatments and nutrient management as subplot treatments. results revealed that yield attributes such panicles per square metre grains panicle were significantly influenced by both higher values recorded Zero + Residue (239; 122) among site specific (SSNM) based on Nutrient expert® (228; 119) respectively whereas, length, test weight harvest index not any or practices. increased grain straw direct seeded rice to tune 14.03% (grain); 9.27% (straw) and, 10.15%(grain); 6.1% over Conventional tillage, respectively. While SSNM 60% RDN GSGN 100% PK of, RDF 14.91%; 7.73% 12.07%; 5.52% RDF, resulted maximum gross returns (₹ 91451, ₹ 91321 /ha); net 59050, 59313 /ha) BCR (1.83, 1.86)
