Effect of integrated weed management on growth, yields and nutrient balance in direct seeded rice (Oryza sativa)
Year: 2021
Type: article
Abstract: A field study was carried out during the rainy (Kharif) season of 2014 and 2015 at Varanasi, Uttar Pradesh, to study the effect of integrated weed management on growth, yields and nutrient balance in soil in direct seeded rice (Oryza sativa L.).Penoxsulam 35g/ha at 10 DAS fb 1 HW at 35 DAS significantly improved plant height, dry matter accumulation, leaf area index, chlorophyll content.Consequently, Penoxsulam 35g/ha at 10 DAS fb 1 HW at 35 DAS influenced statistically grain and straw yields.Penoxsulam 35g/ha at 10 DAS fb 1 HW at 35 DAS had lower nutrients (NPK and Zn) depletion by weeds and higher nutrients (NPK and Zn) uptake by crop in comparision of hand weeding at 15 and 35 DAS in rice during both the years of experimentation.
