Abstract

At the College Farm, Navsari Agricultural University, Navsari (Gujarat), a field experiment was carried out in the summer and kharif of 2021 and 2022. The study included four main plot treatments, namely, T1: Green gram, T2: Cowpea, T3: Dhaincha and T4: Fallow which were sown in summer season, replicated thrice in a randomized block design. Summer legume residues, namely green gram (T1) and cowpea (T2), were incorporated after final crop harvest, while dhaincha (T3) was incorporated at 50% flowering in corresponding plots. Each main plot treatment was carried out throughout the kharif season was divided into six sub-plot treatments as levels of recommended dose of fertilizer to kharif rice, which include W1: 100% RDF, W2: 75% RDF, W3: 50% RDF, W4: 75% RDF + 25% N from FYM, W5: 50% RDF + 50% N from FYM, and W6: No-fertilizer application; resulting in twenty-four treatment combinations replicated thrice in a split plot design. Results posed that the higher (₹/ha 95332, 108322, 101744), net returns ((₹/ha 33478, 46044, 39678) was also recorded higher in rice grown in dhaincha incorporated plots with BCR of 1.54, 1.74, 1.64 in 2021, 2022 and in pooled study respectively. With the application of 100% RDF, maximum gross and net returns (/ha 111152, 51341; 125096, 64761; 118050, 57977) and BCR (1.86, 2.07, 1.97) were greater, while the lowest BCR (1.05, 1.21, 1.13) was in 2021, 2022, and on a pooled basis. Higher gross and net returns were observed in the green gram-rice cropping sequence during the pooled study, with a BCR of 2.22 in the treatment green gram-100% RDF (T1W1) and the lowest being in treatment T4W6 (1.03). Based on the findings of the two-year experiment, it was observed that introducing dhaincha with 100% RDF (Recommended Dose of Fertilizer) yielded positive financial outcomes. Additionally, considering the cropping sequence, it was determined that green gram during the summer season followed by rice cultivation with 100% RDF resulted in greater financial advantages.

Conclusion

Dhaincha incorporation considerably increased gross return, net return, and BCR over other summer legumes and fallow. With 100% RDF, the gross return, net return, and BCR all increased. Similarly, at 100% RDF, rice crops sown after dhaincha incorporation had a much higher net return and B:C ratio than crops sown following summer fallow with no fertilizer application. Green gram had a higher rice equivalent with 100% RDF. When the summer legume-kharif rice sequence was assessed, the green gram-rice sequence had better economic returns and BCR.
