Abstract
Integrated nutrient management (INM) plays a crucial role in optimizing growth and productivity in Indian mustard (Brassica juncea L.). The present study in Mewar University, 2024-25, evaluated the effect of different INM treatments on plant growth, biomass accumulation, and yield components. The results demonstrated that increasing nutrient integration significantly enhanced vegetative growth parameters, including plant height, plant population, and dry matter accumulation at both 30 and 60 DAS. Yield-attributing traits such as siliqua length, number of siliquae per plant, seeds per siliqua, and 1000-seed weight also improved markedly under INM. Among all treatments, T10 consistently recorded the highest growth and yield, producing a maximum seed yield of 2630 kg/ha and biological yield of 7490 kg/ha, along with the highest harvest index and leaf area index. The findings highlight the synergistic benefits of integrating organic and inorganic nutrient sources, which enhance nutrient uptake efficiency and promote balanced crop development. Overall, INM proved to be an effective strategy for improving the productivity and resource-use efficiency of Indian mustard, supporting its adoption in sustainable agriculture systems.
