Study on yield potentiality and spatial requirement of rice varieties (Oryza sativa L.) in system of rice intensification (SRI) under red and laterite zone of West Bengal, India
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 1
Abstract
Field experiment was conducted at Rice Research Station, Bankura during kharif season 2009 and 2010 to study the yield potentiality and spatial requirement of rice varieties in system of rice intensification (SRI) under red and laterite zone of West Bengal. The experiment was laid out in a randomized complete block design (RCBD) in a three replications with two rice varieties (Swarna and Lalat). Performances of swarna and lalat varieties in SRI as compared to conventional method of rice cultivation (CMRC) were investigated. Swarna (MTU 7029) has yielded maximum grain yield (6.07, 5.66 and 5.86 t ha-1 during 2009, 2010 and in pooled, respectively) from the treatment T7 (25 × 25 cm spacing) under SRI. Lowest grain yield (3.55, 3.23 and 3.38 t ha-1 during 2009, 2010 and in pooled, respectively) was recorded from treatment T9 (Lalat at 20 × 15 cm spacing) under CMRC. SRI technology has potential in increasing more grain yield, it saves seed requirement and irrigation water and chemical fertilizer considering than conventional method of cultivation. Rice cultivation is more sustainable and profitable for the farmers in SRI under the red and laterite zone of West Bengal.
