Abstract: A field investigation was conducted during the rainy (Kharif) season of 2014 and 2015 at Varanasi, Uttar Pradesh, to study the impact of integrated weed management on weeds, growth attributes and yield of direct seeded rice (Oryza sativa L.). At 30, 60, 90 DAS and at harvest, amongst the integrated weed management treatments, penoxsulam 35 g/ha at 10 DAS fb 1 hand weeding at 35 DAS reduced total weed density and their dry weight than penoxsulam 35 g/ha at 20 DAS fb 1 hand weeding at 35 DAS thus resulting in the lowest weed index. Penoxsulam 35 g/ha at 10 DAS fb 1 hand weeding at 35 DAS markedly improved growth attributes viz., plant height, dry matter accumulation, leaf area index and chlorophyll content at 90 DAS. Penoxsulam 35 g/ha at 10 DAS fb 1 hand weeding at 35 DAS statistically influenced the grain and straw yields. Bispyribac Na 25g/ha at 10 DAS fb 1 HW at 35 DAS had the highest harvest index over all other treatments in the year of 2014.
