Effect of nitrogen and zinc, iron application on growth and yield attributes of rice

Abstract

A field experiment was conducted to determine the influence of Nitrogen and Zinc, Iron on growth and yield of Rice at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the Kharif season of 2023. The experiment was laid out in Randomized Block Design with ten treatment Combinations and three replications in which there were three levels of zinc and iron (10,15 and 20 kg/ha) and three levels of (Nitrogen 80,70, 60 kg/ha) and Nano urea (2, 3, 4 ml/L)) and a control (120-60-60 NPK kg/ha). Among the various treatment combinations Significantly highest plant height (104 cm), number of tillers/hill (16.00), dry weight (52.13 g/hill), number of productive tillers/m2 (297.48), number of grains/panicle (84.50), test weight (18.07 g) were recorded in treatment-9 with application of Nitrogen 60 kg/ha, Zinc 20 kg/ha and Iron 20 kg/ha along with Nano Urea 2 ml/L in rice crop.
