Abstract
An investigation was conducted during the kharif seasons of 2023 and 2024 to assess the impact of integrated nutrient management on nutrient content and uptake in basmati rice. The experiment was laid out in a randomized block design (RBD) with 11 treatment combinations and three replications of various doses of NPK, poultry manure, and biofertilizers. The findings showed that, compared to other treatments, the highest nutrient content was obtained under treatment 75% RDF + PM + NPK Consortia + ZSB, root dipping each @ 20 ml/l. Specifically, the treatment resulted in nitrogen content of 1.33% in grain and 0.45% in straw, phosphorus content of 0.37% in grain and 0.24% in straw, potassium content of 0.38% in grain and 1.46% in straw, and Zinc content of 66.20 ppm in grain and 61.30 ppm in straw. Furthermore, the highest nutrient uptake was recorded, with nitrogen uptake of 56.44 kg/ha in grain and 29.13 kg/ha in straw, phosphorus uptake of 17.82 kg/ha in grain and 18.30 kg/ha in straw, potassium uptake of 18.26 kg/ha in grain and 107.44 kg/ha in straw, and Zinc uptake of 320.32 g/ha in grain and 452.16 g/ha in straw.
