Effect of Fertility Levels and Weed Management Practices on Weed Species and Weed Dry Matter Accumulation

Abstract

The present investigation was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi season of 2019-20. The experiment was laid out in Factorial Randomized block design with three replications keeping four fertility levels viz., 100% RDF-IF (150 kg/h), 125% RDF-IF (25% through FYM), 100% RDF + 25%RDN through FYM, 75%RDF-IF+25%RDN through FYM and four weed management practices Weedy Check, Weed free up to 60 days, Sulfosulfuron @ 30 g/h + Carfentazole @ 20 g/h, Clodinafoppropagynol(60 g) + metsulfuron(4 g)=(64 g/h). Results revealed that among fertility levels application of 125% RDF-IF (25% through FYM) and in weed management practices weed free followed by125% RDF-IF (25% through FYM)+Clodinafoppropagynol (60 g) + metsulfuron (4 g)=(64 g/h) a.i ha-1 proved as superior than other treatments with respect to weed population, nutrient loss by weed, dry matter accumulation in weed, was found with the application of 125% RDF-IF (25% through FYM) and weed free treatment combination.
