Effect of Weed Management Practices on Growth and Economics of Transplanted Rice under Sodic Soil

Effect of Different Weed Management Practices on Nutrient Removal, Nutrient Uptake and Grain Yield of Transplanted Rice (Oryza sativa L.) under Sodic Soil Ecosystem

“…This finding was close conformity with that of Nivetha et al, (2017) who reported the lesser weed density and dry weight on 60 DAT in transplanted rice with pre emergence application of bensulfuron methyl + pretilachlor followed by early post emergence application of bispyribac sodium. Significantly higher total weed density (116.8 and 144.9 m -2 ) and dry weight (106.4 and 195.4 g m -2 ) registered with unweeded control at 40 and 60 DAT, respectively as compared to other treatments.…”

Date of Transplanting and Integrated Weed Management Effects on Growth and Yield of Black Rice (Oryza sativa L.) under SRI

“…W hen rice fields are not flooded continuously and plants are widely spaced as recommended under SRI, weeds get a better chance to grow. Weeds become detrimental to crops by changing the pH of soil, decreasing the nutrient availability, which in turn reduces straw yield by 13-38% and grain yield by 25-47% (Manandhar et al, 2007, Nivetha et al, 2017, Paul et al, 2019and Tasmin et al, 2019. Therefore, efficient weed management practices are required under SRI.…”
