Abstract
The present investigation entitled "Evaluation of new herbicides and its
combination for effective weed management in Chickpea (Cicer arietinum L.)"
was carried out during Rabi season of year 2017-18 and 2018-19 at Agronomy
Research Farm, Acharya Narendra Deva University of Agriculture and Technology.
Kumarganj, Ayodhya (U.P.). 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 laid out in Randomized Block Design with three
replication. The results revealed that all the growth parameters and yield attributes
were significantly influenced through different treatments during course of
investigation. On the basis of the experiment conducted during rabi 2017-18 and
2018-19, 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, grain yield and
economics of chickpea followed by oxyfluorfen 200 g ha-1 as PE along with postemergence
application of quizalofop ethyl 60 g ha-1 each.
