Abstract
A field study titled“Response of Integrated Nitrogen Management through Organic and Inorganic Sources on Growth and Yield of Mustard (Brassica juncea L.)” was carried out during the Rabi season of 2024–25 at the agricultural research farm of Vivekananda Global University, Jaipur. The main objective was to evaluate the impact of different INM practices on the growth, yield, quality, soil fertility, and economic performance of Indian mustard. The findings demonstrated that INM significantly enhanced various growth parameters, yield attributes, and overall crop productivity. Among the treatments, T9-comprising 75% (RDN- Recommended Dose of Nitrogen) supplemented with 25% nitrogen through an equal mix of vermicompost, poultry manure, and farmyard manure (1:1:1)-consistently delivered the best results. This treatment recorded the maximum values for plant height, number of primary branches, dry matter accumulation, leaf area index (LAI), and crop growth rate (CGR). Although variations in relative growth rate (RGR) were statistically non-significant, chlorophyll content was considerably higher in T9, followed by T6 and T8. Yield-contributing traits such as siliqua length, siliquae per plant, seeds per siliqua, and test weight showed notable improvements under INM, with T9 producing the highest seed yield of 40.84 q/ha, almost three times greater than the control (13.45 q/ha).
Quality indicators like protein and oil content were also significantly enhanced, with T9 showing a protein content of 23.16%. Based on these findings, T9 is recommended for maximizing mustard yield and improving soil fertility in Western Uttar Pradesh, while T6 serves as a viable alternative for those seeking high returns with relatively lower input costs.
