- Abstract
The field studies were conducted at Instructional Farm, College of Agriculture, Jodhpur (Agriculture University, Jodhpur), Rajasthan, India on Wheat during rabi seasons (November to April) of both the 2018-2019 and 2019-2020. The experiment was consisted of three fertility levels viz., 75% of recommended dose of fertilizer (90-30 kg N-P2O5 ha-1), 100% of RDF (120-40 kg N-P2O5ha-1) and 125% of RDF (150-50 kg N-P2O5 ha-1)] and sub-plots: seven post-emergence herbicides (trisulfuron 15 g ha-1, sulfosulfuron 75%+metsulfuron methyl 5% (ready-mix) 32 g ha-1, clodinafop-propargyl 15%+metsulfuron methyl 1% (ready-mix) 64 g ha-1, carfentrazon 20 g ha-1, metsulfuron methyl 4 g ha-1, weedy check and weed free) in split plot design and replicated thrice. Findings revealed, application of 100% recorded the higher growth attributes viz, plant height, dry matter accumulation (g-2) and leaf area index at 50 DAS, yield parameters viz, effective tillers m-1 row length, and grain, straw and biological yield of wheat over 75% RDF, however it was at par with 125% RDF. Among the post-emergence herbicides, the herbicide clodinafop-propargyl 15%+metsulfuron methyl 1% (ready-mix) 64 g ha-1 significantly increased the growth and yield parameters and yield, while remaining at par with sulfosulfuron 75%+metsulfuron methyl 5% (ready-mix) 32 g ha-1 and proved superior in comparison to rest of the treatments. Maximum nutrients (NPK) depletion by weeds was recorded with the application of 125% RDF. Among herbicides, clodinafop-propargyl 15%+metsulfuron methyl 1% (ready-mix) 64 g ha-1 was also obtained significantly minimum nutrients depletion by weeds.
