Abstract:

The influence of different crop establishment methods and weed management practices on productivity and economics of rice was studied at College Farm, College of Agriculture, ANGRAU (Hyderabad) during the kharif season 2010 and 2011 in sandy loam soils. The experiment was laid out in split plot design and replicated thrice with three crop establishment methods i.e. direct sowing of sprouted seeds under puddled condition, SRI and transplanting as main plot treatments and four weed management practices i.e. bensulfuron methyl 60 g + pretilachlor 600 g a.i ha-1 as pre emergence followed by mechanical weeding at 30 DAS/T, bispyribac sodium @ 25 g a.i ha-1, farmer’s practice and weedy check were assigned as subplot treatments. The results revealed that among rice establishment methods, transplanting of rice recorded significantly higher grain yield, straw yield, gross returns and net returns. However, higher B:C ratio was observed with SRI method of establishment. Among weed management practices, higher grain yield, straw yield, gross returns and net returns were registered with farmer’s practice however, bensulfuron methyl + pretilachlor mixture @ 60 + 600 g a.i ha-1 followed by mechanical weeding at 30 DAS/T resulted in higher B:C ratio.


Keywords: Establishment methods, weed management practices, transplanting and yield.
