Impact of live mulches, cover crops and herbicides on weeds, growth attributes and yield of direct seeded rice (Oryza sativa L.)

Author(s): Pratik Sanodiya and Manoj Kumar Singh
Abstract: A field investigation was conducted during the rainy (Kharif) season of 2014 and 2015 at Varanasi, Uttar Pradesh, to study the impact of live mulches, cover crops and herbicides on weeds, growth attributes and yield in direct seeded rice (Oryza sativa L.). At 30, 60, 90 DAS and harvest, amongst the weed management treatments, Sesbania cover crop fb bispyribac Na 25 g/ha + azimsulfuron 30 g/ha at 15 DAS reduced total weed density and dry weight than sunhemp cover crop fb bispyribac Na 25 g/ha + azimsulfuron 30 g/ha at 15 DAS thus resulting in the lowest weed index except hand weeding at 15 and 35 DAS. At 90 DAS, Sesbania cover crop fb bispyribac Na 25 g/ha + azimsulfuron 30 g/ha at 15 DAS markedly improved plant height, dry matter accumulation, leaf area index, chlorophyll content during both years. Sesbania cover crop fb bispyribac Na 25 g/ha + azimsulfuron 30 g/ha at 15 DAS improved grain and straw yields during both years but higher harvest index in 2014 as compared to sunhemp cover crop fb bispyribac Na 25 g/ha + azimsulfuron 30 g/ha at 15 DAS.
