Abstract:
An agronomic investigation to study the response of integrated n weed management (IWM) in wheat crop. Experiment was conducted during Rabi season of year 2020-21 an agricultural Farm at Rama University, Kanpur 209217 (U.P) India. The experiment was laid out in Randomized Block Design with three replications and 12 treatments viz. T₁-Pendimathelin 30 EC @ 1’0 kg ha ^-1, T₂ – Metribuzin 70 WP @ 0.3 kg ha ^-1, T₃ – Metsulfuron 10 EC @ 0.02 kg ha -1 25 DAS, T₄– Pendimethalin 30 EC @ 1.0 kg ha^-1+ one hand weeding 40 DAS, T₅– Pendimethalin 30 EC @ 1.0 kg ha^-1+ one hand weeding 40 DAS, T₆ – Metribuzin 70 WP @ 0.3 kg ha^-1+ one hand weeding 40 DAS, T₇– Metribuzin 70 WP @ 0.30 kg ha^-1+ 2,4-DEE@ 0.5 kg ha^-1 25 DAS, T₈– Pendimethalin 30 EC @ 1.0 kg ha^-1+ Metsulfuron 10 EC @0.3 kg ha^-1 25 DAS, T₉ – Metribuzin 70 WP @ 0.3 kg ha^-1+Metsulfuron 10 EC @ 0.02 kg ha^-1 DAS, T₁₀ – 2,4-122DEE @ 0.5 kg ha ^-1 25 DAS, T₁₁ – Weeds free check (Two hand weeding 25 and 45 DAS), T₁₂– Control. Higher growth attributing characters at different crop stages and yield attributing characters at harvest viz. plant height, number of tillers, leaf area index, plant dry matter, length of ear, number of grains per ear and test weight were produced with weeds free (Two hand weeding 25 and 45 DAS). Similarly, higher grain yield, straw yield, biological yield and harvest index along with gross return, net return and B: C ratio was recorded with Weeds free check (Two hand weeding 25 and 45 DAS)treatment as compared to all the other treatments in wheat crop.
