RÉSUMÉ
This research paper aims to evaluate the agronomic performance of twenty rice hybrid varieties under the specific agro-climatic conditions of Prayagraj, Uttar Pradesh, India. The study focuses on analyzing their growth and yield parameters using a randomized block design replicated thrice. The findings will provide valuable insights into the performance of rice hybrids and assist farmers in selecting suitable varieties for optimal productivity in the region. During Kharif season, of 2022 the field experiment was conducted at Crop Research Farm, Department of Agronomy, Sam Higginbottom Institute of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.). Based on the objectives taken maximum plant height (122.57 cm), number of tillers (15.07), plant dry weight (55.91 g/plant), panicle length (29.00 cm), filled grains (256.17), were recorded significantly higher in the hybrid R-504 as compared to other treatments though grain yield/hill (29.13 g) was recorded significantly higher in the hybrid R-410. This research paper aims to provide an in-depth analysis of agronomic evaluation of rice hybrids. The study is intended to explore the advantages and challenges associated with rice hybrid varieties, with a focus on growth attributes, yield potential and other agronomic traits.
