Abstract: The present study was carried out to investigate the impact of Integrated Nutrient Management (INM) on the productivity of toria (Brassica rapa var. Toria) in the rainfed agro-ecosystems of Sonitpur district, Assam, over three consecutive rabi seasons. Seventy-five farmers across five villages were selected for comparing INM practices using high-yielding toria variety TS 67 with local farmer practices. Results revealed that an average yield increase of 23% in INM plots over check plots, with the highest yield gain (26.2%) recorded in 2021-22. Soil analysis before and after the cropping seasons also demonstrated marked improvement in organic carbon (23.4% increase) and available macronutrients (N, P, K) in INM-treated fields. Economic analysis showed higher gross and net returns in demonstration plots. Yield gap analysis confirmed a reduction in both technology and extension gaps under INM.
