Indian mustard (Brassica spp.) is a major Rabi oilseed crop of India, and its productivity is strongly influenced by balanced nutrient management. A field experiment was conducted during the Rabi season of 2022-23 at the Rajoula Agricultural Farm, MGCGV, Chitrakoot, Satna (Madhya Pradesh), to evaluate the effect of integrated nutrient management on mustard under Kymore Plateau conditions on yield, quality, and nutrient uptake of mustard (Pusa Mahak variety). The experiment was laid out in a randomized block design with nine treatments comprising different levels of NPK fertilizers, farmyard manure (FYM), and their combinations, replicated three times. Results revealed significant variations in seed yield, Stover yield, oil content, oil yield, and nutrient uptake due to different nutrient management practices. Seed yield ranged from 715.09 to 1555.80 kg ha⁻¹, with the highest yield recorded under IPNS treatment T₆ (40:20:10 NPK + 5 t FYM ha⁻¹), which was significantly superior to all other treatments. The same treatment also registered maximum oil content (36.48%), oil yield (567.94 kg ha⁻¹), and the highest uptake of nitrogen, phosphorus, and potassium in seed, Stover, and total biomass. Integrated nutrient treatments consistently outperformed sole application of inorganic fertilizers or FYM, while the control recorded the lowest values for all parameters. The enhanced performance under INM was attributed to improved nutrient availability, better nutrient-use efficiency, and improved soil health. The study concludes that application of IPNS (40:20:10 NPK + 5 t FYM ha⁻¹) is the most effective and sustainable nutrient management strategy for improving productivity, quality, and nutrient uptake of mustard under Kymore Plateau agro-climatic conditions.
