Assessment of protein rich rice varieties CR Dhan-310 and CR Dhan-311 at different agro-climatic zones of Odisha

Abstract

An On-Farm multilocational trial was carried out at farmers field in 4 districts of Odisha during Kharif 2020-21 and 2021-22 to evaluate the performance of protein rich rice varieties CR Dhan-310 and CR Dhan-311 which were compared to the farmers variety Lalat. CR Dhan-310 recorded the highest plant height (108.2 cm), effective tillers plant-1 (13.1), no of panicles m-2 (311.7), 1000 grain weight (23.64 g) with yield of 44.6 q ha-1 followed by variety CR Dhan-311 recorded plant height 107.5 cm, no. of effective tillers plant-1 was 11.42, no. of panicles m-2 was 281.2, 1000 grain weight 22.2 g with yield of 41.3 q ha-1 followed by farmers variety Lalat with plant height 93.1 cm, effective tillers plant-1 is 10.1, no of panicles m-2 was 270.8, 1000 grain weight 20.8 gm with yield of 39.3q ha-1.
