Effect of summer legumes incorporation on quality parameters of succeeding Kharif rice

Abstract

In Navsari, Gujarat, at the College Farm of Navsari Agricultural University, a field experiment was conducted in the summer and kharif of 2021 and 2022. With 4 main plots and 6 subplot treatments, the experiment comprised of twenty-four treatment combinations that were replicated 3 times in a split plot design. Results posed that significantly higher milling quality parameters and protein content of rice was found when rice grown in dhaincha incorporated plots (T3) and it was followed by green gram (T1), cowpea (T2) incorporated plots, and significantly lower values were seen in the fallow treatment (T4) for both years and in the pooled analysis. However, amylose and amylopectin content in rice was non-significant during the study. In the case of recommended levels tested during kharif in rice, significantly higher values of milling quality parameters, amylose, amylopectin, and protein content percentage were higher with application of 100% RDF (W1) and fb 75% RDF + 25% N from FYM (W4) during 2021-2022 and in pooled basis. Whereas the treatment No-fertilizer application (W6) recorded lower values throughout both the years and on a pooled basis. The experimentation revealed that dhaincha incorporation and 100% RDF proved as better in enhancing milling quality attributes and protein content whereas amylose and amylopectin percentages did not vary under residue incorporation.
