A field experiment was conducted during 2011-2012 at the Instructional farm, Uttar Banga Krishi Viswavidyalaya pundibari, Cooch Behar, West Bengal during the Boro season to find out the effect of grain yield of rice cultivars under different methods of rice cultivation (SRI and conventional) at a given soil moisture content. The yield attributes of rice among the different varieties (Pioneer, RH664, Lalat and GB-1) in both SRI and conventional systems were recorded. The maximum yield ( t ha-1 ) in RH664 under SRI over the other was observed, while maximum yield ( t ha-1 ) for GB-1 was observed under the conventional method of cultivation. The maximum straw yield of (t ha-1 ) in GB-1 under SRI over the other was observed, while the straw yield of t ha-1 in GB-1 was observed under the conventional method of cultivation. | Performance of rice cultivars under different methods of tillage operation
