Evaluation of rice (Oryza sativa L.) hybrids under agro-climatic conditions of Prayagraj (U.P)

The Agronomic investigation entitled Evaluation of Rice (Oryza sativa L.) Hybrids under Agro-climatic conditions of Prayagraj were 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 of to study growth and yield attributes of rice hybrids and to study the economics of different rice hybrids. The field experiment was carried out in randomised block design with three replication having 15 different rice hybrids as treatments. The finding of the experiment indicated that the growth and yield parameters like maximum plant height (121.17 cm), higher number of tillers (14.33), maximum plant dry weight (57.69g) higher number of effective tillers (440.0 tillers/m2), panicle length (31.36 cm), maximum no of filled grain/panicle (160.67), test weight (22.67 g) and maximum grain yield (8.42 t/ha) were recorded in hybrid KR-39. The economics of the hybrid KR-39 was also found higher i.e. Maximum Net return (₹ 66659.91/ha), Gross returns (₹ 118201.6/ha) and B: C ratio (2.29).
