Rape (Brassica napus L.) is an essential source of edible oil. The growing demand for rapeseed oil seeks to devise nutrient management strategies to lessen the gap between actual and potential yields. A field experiment was investigated at MRCFC, SKUAST-Kashmir, focusing on the best nutrient management practice for realizing higher yield in Brassica napus, using the nutrient omission plot technique. The yield and yield components of oil seed rape responded significantly to nutrient omissions. Treatments comprising NPKS + FYM, NPKS, NPK, NP, PK, NK, and control with three replications were carried out in randomized block design. Significantly, the highest seed yield of 1250 kg ha−1 was registered with NPKS + FYM, with a yield superiority of 143% over control. In terms of yield attributes, the number of pods plant−1 was the key contributor to yield. Response toward the nutrients followed the order of N > P > S > K. Application of FYM was observed to increase the efficiency of accompanying nutrient particularly for P (6.6%). Combined application of the nutrients leads to improvement in the nutrient efficiency of major nutrients evaluated in terms of agronomic efficiency (AE), physiological efficiency, and apparent nutrient recovery (ANR) efficiency. Based on the outcome of the results, balanced application of chemical fertilizers in combination with FYM seems to be pivotal for harnessing the potential of individual nutrients toward achieving higher yield in Brassica napus.
