Abstract: A field experiment was conducted during Kharif season of 2015 at Crop Research Centre Chirauri, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) The experimental soil was low in organic carbon, nitrogen and medium in available P and K. The experiment was conducted in RBD with three replications comprising fifteen weed management practices viz. Imazethapyr @ 70 g ha-1 as pre plant incorporation, Imazethapyr @ 80 g ha-1 as pre plant incorporation, Imazethapyr @ 70 g ha-1 as pre emergence, Imazethapyr @80 g ha-1 as pre emergence, Imazethapyr @ 70 g ha-1 at 3-4 leaf Stage, Imazethapyr @ 80 g ha-1 at 3-4 leaf Stage, Imazethapyr +imazemox (RM) @ 70 g ha-1 as pre emergence, Imazethapyr +imazemox (RM) @ 80 g ha-1 as pre emergence, Imazethapyr +imazemox (RM) @ 70 g ha-1 at 3-4 leaf Stage, Imazethapyr +imazemox (RM) @ 80 g ha-1 at 3-4 leaf Stage, Pendimethalin @ 1000 g ha-1 as pre emergence, Imazethapyr + Pendimethalin (RM)@ 1000 g ha-1 as pre emergence, Hand weeding at 20&40 DAS, Weed free and Weedy check. The result shows that at 30, 60 DAS and at harvest, highest weed control efficiency (93.0, 79.0 and 81.6 %) were recorded with two hand weeding at 20 and 40 DAS. At 30 DAS among the herbicidal treatments (78.1 %) was recorded with PRE application of Imazethapyr + Pendimethalin (RM) @ 1000 g ha-1 followed by PRE application of Imazethapyr @80 g ha-1 (71.5 %). At 60 DAS, among the herbicidal treatments, maximum weed control efficiency (63.8%) was recorded with POE application of imazethapyr + imazemox (RM) @ 80 g ha-1 followed by POE application of imazethapyr + imazemox (RM) @ 70 g ha-1 (61.5%). At harvest, significantly highest weed control efficiency (78.1%) was recorded with POE application of imazethapyr + imazemox (RM) @ 80 g ha-1 followed by POE application of imazethapyr + imazemox (RM) @ 70 g ha-1 (75.3%).
