Response of integrated nutrient management on growth and yield attributes of rice (Oryza sativa L.)

Abstract

The experiment entitled “Response of Integrated nutrient management on growth and yield attributes of Rice (Oryza sativa L.)” for the two consecutive years, beginning from kharif season 2023 and 2024 at CRF, Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj-211007, UP. The trial was laid down in RBD with sixteen treatments of rice which replicated thrice. The application plot size is 2x2m. Transplanting was done with spacing row to row and plant to plant 15x15 with two plants per hill at depth of 5 cm. the value of growth, yield and yield attributes viz., plant height (cm) (123.15), tillers (No.) (332.56m-2), dry weight plant-1 (45.95 g), crop growth rate (26.32g/g/day), leaf area index (6.59 lai), rice leaf n content (45.38 spad value), net assimilation rate (3.89 g/day/m2), panicle plant-1 No. (15.82), filled grain panicle-1 No. (136.43), length of panicle (31.48cm), test weight (33.26g), grain yield q ha-1 (61.09), straw yield q ha-1 (96.05) & harvest index (38.88%) of rice were significantly higher in T14RDF + V.C + Zn 100% SA.
