SUMMARY
A field experiment was conducted at Agricultural Farm, Krishi Vigyan Kendra, Damla (Yamunanagar) of CCSHAU, Hisar during Rabi, 2019-20. The study was conducted on HD 3086 variety of wheat crop grown in split plot design with six main plot and three subplot treatments in three replications. The main plot comprised of various residue management practices: Combine harvesting of paddy without SMS, burning of crop residues and sowing of wheat by conventional tillage method; Combine harvesting of paddy without SMS, residue shredding with mulcher followed by happy seeder sowing of wheat; Combine harvesting of paddy without SMS, direct sowing of wheat with happy seeder; Combine harvesting of paddy with SMS followed by sowing of wheat using happy seeder; Combine harvesting of paddy without SMS, residue shredding with straw chopper followed by happy seeder sowing of wheat; Manual harvesting of paddy, residue removal and sowing of wheat with conventional tillage practice. Subplot treatments comprised of different fertilizer levels: 75% RDF, 100% RDF and 125% RDF. The investigation was planned with the objective of improving the production as well quality of wheat fodder. Results of the experiment revealed that among different residue management practices, treatment having residue shredding with mulcher followed by happy seeder sowing of wheat (C0R2T1) improved straw yield, protein content and protein yield by 7.7, 3.30 and 13.06 per cent respectively over Manual harvesting of paddy, residue removal and sowing of wheat with conventional tillage practice (C2R0T3). Among various fertilizer levels, treatment with 125% RDF (Recommended dose of fertilizer) recorded higher straw yield, protein content and protein yield by 12.7, 8.74 and 24.35 per cent respectively compared to 75% RDF treatment.
Key words: Residue, fertilizer, happy seeder, mulcher
