Integrated weed management in chickpea (Cicer arietinum l.)

A field experiment was conducted during rabi 2006–07 to 2008–09 at RARS, Lam Farm, Guntur to find out most suitable integrated weed management practice for control of weeds in chickpea. Results indicated that weed control treatments significantly reduced the density and dry weight of weeds in chickpea. Post-emergence application of imazethapyr 63 g/ha caused 20% crop injury among the herbicides under study. Integrated treatments were found to be superior (83–89% WCE) to alone application of herbicides. Among the treatments, pre-emergence application of oxyfluorfen 100 g/ha fb hand weeding at 30 DAS recorded maximum (2272 kg/ha) and was on par with all other integrated treatments and also with hand weeding at 15 and 30 DAS. Among the individual herbicides, pre-emergence application of pendimethalin 1.5 kg/ha recorded maximum grain yield and was on par with other individual herbicides.
