Nutrient Depletion by Weeds as Influenced by Different Weed Management Measures in Soybean grown on Vertisols of S-E Rajasthan
Year: 2022
Type: article
Abstract: The field experiment conducted during the rainy season of kharif 2021 showed that weeds in soybean depleted the soil fertility by removing 69.2 Kg N, 12.4 Kg P and 76.7 Kg K under unweeded check.All weed control measures reduced weed dry matter and nutrient depletion by weeds at all the stages.Two hand weedings, ready mixture of fomesafen + fluazifop-p-butyl 220 g a.i./ha were significantly superior in reducing weed dry matter and nutrient depletion by weeds at 30, 60 DAS and at harvest stage over rest of the treatments.All weed control measures significantly enhanced seed & straw yield of soybean over weedy check.Two hand weedings and mixture of fomesafen + fluazifop-p-butyl 220 g a.i./ha, sodium aciflorfen + clodinafop-propargyl 245 g a.i./ha and propaquizafop + imazethapyr 125 g a.i./ha , were at par and were found to be significantly superior over rest of the treatments in enhancing seed and straw yield.Ready mix application of fomesafen + fluazifop-p-butyl 220 g a.i./ha, propaquizafop + imazethapyr 125 g a.i./ha and sodium acifluorfen + clodinafoppropargyl 245 g a.i./ha were significantly reduced the NPK depletion by grassy, broad leaved weeds and sedges and significant improve nutrient uptake by soybean and consequently gave higher seed yields.
