Abstract

Pendimethalin 1000 g/ha as pre-emergence effectively controlled C. album, M. denticulata and Phalaris minor. Pinoxaden 50 g/ha and clodinafop 60 g/ha as post-emergence were effective in controlling only P. minor. Pinoxaden and trifluralin were slightly phytotoxic to chickpea plants, which recovered later on. The highest grain yield was obtained in weed free treatment which was at par with two hand weeding, pre-emergence use of pendimethalin at 1000 g/ha fb pinoxaden at 50 g/ha applied at 45 DAS and pendimethalin at 1000 g/ha fb clodinafop at 60 g/ha applied at 45 DAS. Presence of weeds throughout crop season reduced the seed yield up to 68%.
