Effect of different pre- and post-emergence herbicides for weed management in chickpea

A field experiment was conducted during the winter (Rabi) season 2017-18 at Instructional Agronomy Farm of Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment consisted of twelve weed management treatments which were replicated thrice in Randomize Block Design. Chickpea (cv. Pratap Chana-1) was used as a test crop. The hand weeding twice 30 and 60 days after seeding (DAS) followed by pre-emergence application (PE) of pendimethalin 1000 g/ha or pendimethalin 750 g/ha have significantly reduced total weed density and biomass and attained the highest chickpea seed yield. The net return and B:C ratio was significantly higher with pendimethalin 1000 g/ha PE and pendimethalin 750 g/ha PE due to lesser cost of herbicides usage compared to hand weeding.
