Abstract
A field experiment was conducted during July to November 2017 at Wetland farm of Tamil Nadu Agricultural University, Coimbatore to study the effect of different crop establishment techniques on growth, yield attributes and yield of rice under puddled condition. The results revealed that crop established through square planting (SRI) with single seedling has recorded significantly higher in growth attributes, root characters, leaf area index, number of productive tillers sq.m-1 (595), panicle length (23.4 cm), total number of grains panicle-1 (152.7), number of filled grains panicle-1 (137.7), fertility percentage (90.2), grain yield (6860 kg ha-1) and straw yield (10180 kg ha-1) compared to other establishment methods. The gross return, net return, B:C ratio and added benefit ( 102680 ha-1, 47082 ha-1, 1.85 and 10932 ha-1, respectively) was higher in square planting (SRI) with single seedling under puddled condition.
