Abstract:
A field experiment was conducted during 2022-23 and 2023-24 at Instructional-cum-Research Farm, Raj Mohini Devi College of Agriculture and Research Station, Ambikapur, Chhattisgarh to study the effect of various residue and nutrient management options on performance of maize-mustard system. The trial consisted of twelve treatment combinations including four vertical factors i.e., Residue removal, Residue incorporation, Residue incorporation + spray of microbial consortium on residue and Zero-tillage + residue retention and spray of microbial consortium on residue and three horizontal factors i.e., 100% RDF, 100% RDN and P and 50% RDK and 75% RDF + 5 t FYM/ha arranged in strip plot design with three replications. The results revealed that significantly higher grain yield (6443 and 1150 kg/ha respectively), stover yield of maize and mustard, respectively and maize equivalent yield and production efficiency of system were obtained with adoption of residue incorporation + spray of microbial consortium, which was at par to residue incorporation and zero-tillage + residue retention and spray of microbial consortium. Among nutrient management options, grain yield (6882.1 and 1174.2 kg/ha), stover yield of maize and mustard, respectively and maize equivalent yield and production efficiency of system were recorded under 100% RDF. The highest gross return (₹ 139.8 and 68.80 × 103/ha) was recorded under residue incorporation + spray of microbial consortium, while net return (₹ 95.83 and 37.05 × 103/ha) and B: C ratio (2.36 and 1.34) were recorded maximum under zero-tillage + residue retention and spray of microbial consortium, followed by residue incorporation + spray of microbial consortium and residue incorporation. Among the nutrient management options, the 100% RDF treatment yielded the highest mean gross return (₹ 149.2 and 70.22 × 103/ha), net return (₹ 104.7 and 37.8 × 103/ha) and benefit-cost ratio (2.35 and 1.18) followed by 100% RDN and P with 50% RDK for maize and mustard, respectively.
