Abstract:
The Agronomic investigation entitled “Evaluation of Rice (Oryza sativa L.) Hybrids under Agro-climatic conditions of Prayagraj, U.P.” was carried out during kharif 2020. The experimental site was located at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) with the objective to study growth and yield attributes of rice hybrids and to study the economics of different rice hybrids. The soil of experimental field is identified as sandy loam in texture, nearly neutral in soil reaction (pH7.2), low inorganic Carbon (0.48%), available N (108.0 kg/ha), available P (22.5 kg/ha) and available K is (280 kg/ha). The field experiment was carried out in Randomized block design with three replications having 15 different hybrids as treatments. The finding of the experiment indicated that KR-14 showed best results in growth parameters like germination percentage, maximum plant height (100.53 cm), higher number of tillers (11.33), maximum plant dry weight (48.16), higher number in Crop growth rate (22.55 g/m2/day), higher number of Relative growth rate (0.016 g/g/day), higher number of effective tillers (340.00 tillers/m2), maximum no. of filled grain/panicle (163.00), maximum test weight (25.00 g), maximum grain yield/hill (27.67 g), maximum grain yield (9.37 t/ha), maximum biological yield (22.89 t/ha) and maximum harvest index (40.96%).
