Abstract

This field study evaluated the effect of various nutrient sources, including NPK, farmyard manure (FYM), consortia, and nano zinc, on rice (Oryza sativa) growth, yield, and soil quality in the Central Zone of Uttar Pradesh. Fourteen treatments were tested using a randomized block design with three replications. The treatment combining 75% NPK, FYM @ 5 tons/ha, consortia, and nano zinc (T8) consistently showed superior results, with the highest plant height (97.09 cm at harvest), maximum dry matter accumulation (36.49 g/m²), and the most effective tillers (181.20/m²). T8 also recorded a significantly higher grain yield (43.6 q/ha) compared to the control (19.79 q/ha). The results demonstrate that integrating FYM, consortia, and nano zinc with reduced NPK enhances rice growth and yield, supporting sustainable rice production in the region.
