Abstract: A field experiment was conducted at university farm of Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India on summer rice during 2015-2016 and 2016–2017 to observe the performance of hybrid varieties under New Alluvial Zone of West Bengal. The experiment was laid out in Randomized Block Design with three replications. Square method of transplanting (20 cm × 20 cm) was maintained for all varieties (27P22, 27P37, 27P36, 28P67, 27P31, 29P01, ArizeTej Gold, and Arize 6129) and N-P2O5-K2O was applied @ 140:60:60 kg/ha for hybrids. The results of study revealed that the hybrid varieties exhibited superiority in respect of different growth parameters like plant height, LAI, aerial dry matter accumulation, number of tillers per hill etc over the control variety HYV Satabdi (IET 4786). Among various tested rice hybrids, maximum grain yield (7.13t/ha) and harvest index (49.65%) were recorded in 28P67. The results of study revealed that both grain and straw yield of hybrid varieties were significantly higher than the HYV Satabdi (control variety) which might be due to better growth parameters and yield components of hybrids.
