The weed management practices consisted of Calotropis gigantea leaf extract spray at three concentrations (10, 20 and 30%) in combination with power weeder operation twice and manual weeding twice.The results revealed that pre-emergence application of Calotropis gigantea at 30 % concentration followed by hand weeding at 40 DAS recorded lower weed density and dry weight and increased the yield in irrigated cotton
