Abstract:
This research aimed to assess the efficacy of integrated nutrient management (INM) on the growth and yield of Indian mustard (Brassica juncea L.). The experiment comprised seven treatments, namely control as 100% recommended dose of fertilizer (RDF): T1; 75% RDF + vermicompost: T2; 50% RDF + vermicompost: T3; 75% RDF + Rhizobium: T4; 50% RDF + Rhizobium: T5; 75% RDF + vermicompost + sulfur: T6; and 50% RDF + Rhizobium + Sulfur: T7, respectively. The experiment was designed in a Randomized Block Design with three replications, and various observations were made on plant growth, the number of primary and secondary branches, yield, and quality parameters. The results of the experiment indicated that the T6 treatment demonstrated the most favorable outcomes in terms of plant height (197.54 cm) at the harvest, number of primary and secondary branches (9.3 and 12.3), and other growth parameters compared to the control treatment. Concerning yield parameters, the same treatment exhibited the highest siliqua length (6.76 cm), test weight (6.26 g), and seed yield (1690 kg/ha), while the lowest yield parameters were observed in the Control treatment (100% recommended dose of fertilizer). Additionally, the T6 treatment recorded the highest oil content (35.76%) and protein content (42.87%), whereas the Control treatment had the lowest quality parameters. Based on the findings of this study, it can be concluded that the T6 treatment showed the most effectiveness in enhancing the growth, yield, and quality attributes of Indian mustard.
