Effect of tillage and crop residue management practices on yield and economics of wheat (Triticum aestivum L.) under conservation agriculture

Abstract

A field experiment was conducted at Experiment farm of Agronomy Department, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during season rabi-2019, to study the effect of tillage and crop residue management practices on yield and economics of wheat (Triticum aestivum l.) under conservation agriculture. The experimental plot was laid out in split plot design of fifteen treatment combinations replicated thrice. Where in main plot consist of three tillage practices viz., Zero tillage (T1), Reduced tillage (T2) and Conventional tillage (T3) and sub plot to five crop residue management practices viz., crop residue @ 2.5t/ha (R1), crop residue @ 5t/ha (R2), crop residue @ 2.5t/ha + consortia @ 5kg/ha (R3), crop residue @ 5t/ha + consortia @ 5kg/ha (R4) and without crop residue (R5).The study of experiment showed that reduced tillage and crop residue application @ 5t/ha + consortia @ 5kg/ha was found significantly higher grain yield. Gross returns, net returns and B:C ratio were recorded highest with reduced tillage and crop residue application @ 5t/ha + consortia @ 5kg/ha. Each increment of tillage and crop residue application correspondingly improved yield as well asgross returns, net returns and B:C ratio of wheat.
