Effect of Integrated Nutrient Management on Yield and Economics of Rice

Abstract

The present investigation was carried out during kharif season of 2022 and 2023 at Students' Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.). The experiment consisted of fourteen different treatments in randomized block design replicated thrice. Soil of the experimental field was sandy loam in texture and slightly alkaline in reaction. The results showed that, on a pooled data basis, the highest grain yield (42.45 q/ha) was achieved with treatment T8, which involved the application of 75 % NPK + FYM + Consortia + Nano Zinc. Similarly, higher straw yields of 69.23 q/ha and 67.00 q/ha were recorded during both years, with T8 also yielding the maximum straw on a pooled basis, followed closely by T14.  Pooled data analysis revealed that T8 achieved the highest grain and straw yields, along with the maximum Benefit-Cost (B: C) ratio of 3.42. The control (T1) consistently recorded the lowest grain and straw yields across both years. The inclusion of FYM, Consortia, and Nano Zinc in INM treatments significantly improved yield performance and soil health, making T8 the most economically viable treatment.
