Abstract:
The investigation was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology. Kumarganj, Ayodhya (U.P.) during Rabi season of year 2017-18 and 2018-19. The experiment was laid out in Randomized Block Design with three replication. The experiment was carried out with 12 treatments viz.: T1- Imazethapyr + imazamox (PRE), T2- Imazethapyr+ imazamox (POE) at 3-4 leaf stage, T3- Imazethapyr (POE) at 3-4 leaf stage, T4- Quizalofop ethyl (POE) at 3-4 leaf stage, T5- Clodinofop (POE) at 3-4 leaf stage, T6- Pendamethalin (PE), T7- Pendamethalin (PE)+ Imazethapyr (POE), T8- Oxyfluorfen (PE), T9- Oxyfluorfen (PE)+ Quizalofop (POE), T10- 1 Hand Weeding at 35-40 DAS, T11- Weed Free and T12- Weedy Check respectively. The objective of the study was to study the bio-efficacy of herbicides and cultural practices on weed control. On the basis of the experiment it may be concluded that pre-emergence application of pendimethalin 1000 g ha-1 along with post-emergence application of either Imazethapyr proved superior over rest of the treatments with respect to weed control efficiency. Weed control efficiency was recorded highest with pendimethalin 1000 g and oxyfluorfen 200 g ha-1 as PE when supplemented with the sequential application of Quizalofop or imazethapyr g ha-1 as PoE each in both of the pre-emergence herbicides (T6 & T7/T8 & T9) over single application of either pendimethalin 1000 g or oxyfluorfen 200 g ha-1 as PE.
