Rice is the most important staple food crop in the world and a major food grain for more than a third of world’s population (Prasertsak and Fukai, 1997). About 40% of world population uses rice as a major source of calories. The use of hybrid rice is a new development in India. Hybrid rice is the commercial rice crop from F1 seeds of cross between two genetically dissimilar parents. A field experiment was conducted during boro season of 2013-14 and 2014-15 in Agricultural Farm, Palli Siksha Bhavana (Institute of Agriculture) at Visva-Bharati, Sriniketan, India which lies in the sub-humid sub-tropical lateritic belt of West Bengal to study the effect of different crop establishment techniques and varieties on growth parameters and yield of hybrid rice. The results showed that between the crop establishment techniques, SRI method showed best results in growth parameters like plant height, CGR, RGR and NAR and also the grain and straw yield of hybrid rice was superior in SRI technique than that of conventional method of rice cultivation in both the years. Among the varieties, Tej variety showed good results in almost all the parameters than that of other varieties but variety NK 6302 also showed good results in case of CGR and RGR than that of Tej variety.
