ABSTRACT

Field experiments were conducted during summer seasons of 2007 and 2008 under irrigated
conditions of Bhadra command area. Among the six establishment methods tried-viz., zero tillage,
drum seeder, normal transplanting, transplanter (manual) method, System of Rice Intensification
(SRI) and aerobic methods, SRI method recorded significantly higher grain yield (6140 kg ha-
1),straw yield (9306 kg ha-1),number of total tillers (448 m-2), effective tillers (376.5 m-2 ),panicle
length (23.5 cm), no. of seed per panicle (94.5),1000 grain weight (27.5 g),net returns (Rs 37086
ha-1) and B;C ratio (2.03) compared to other methods.
