Abstract: A field experiment was conducted during 2022-23 at Agronomy Research Farm, RCSM College of Agriculture, Kolhapur with an objectives to study the effect of different herbicide on yield and uptake of nutrient by sugarcane and weed and their effect on soil fertility. The dominant weed species observed during experiment were Dinebra retroflexa, Brachiaria eruciformis, Digitaria sanguinalis among grasses; Amaranthus viridis, Chrozophora rottleri, Trianthema portulacastrum, Ipomoea hederacea, Portulaca oleracea among broad leaves weed and cyperus iria among sedge. The result showed that the nutrient content with respect to N, P and K percent in weed and sugarcane did not differ significantly due to different weed management practices while highest uptake of nutrient by sugarcane found with weed free treatment over weedy check. Among the herbicidal treatments, post emergence (PoE) application of 2, 4-D amine salt 58% SL @ 1.4 kg a.i ha-1 + Metribuzin 70% WP 0.875 kg a.i ha-1 at 30 Days after planting recorded lowest depletion of nutrient by weed followed by treatment post emergence application of Mesotrione 2.27% + Atrazine 22.7% SC @ 0.875 kg a.i. ha-1 at 30 DAP. Among the herbicidal treatments, highest yield attributes and yield of sugarcane was obtained in treatment 2, 4-D amine salt 58% SL @ 1.4 kg a.i ha-1 + Metribuzin 70% WP 0.875 kg a.i ha-1 at 30 DAP.
