A field experiment was conducted during the rabi season of 2001-02 at N.D. University of Agriculture and Technology, Kumarganj, Faizabad, Uttar Pradesh, India, to study the effect of herbicides on the biochemical and growth parameters of chickpea. The results revealed that all the herbicides promoted various biochemical parameters at 1.0 kg/ha at all the rates. Chlorophyll content was higher compared to the untreated control. These herbicides applied at 1.0 or 1.5 kg/ha increased the nitrate reductase activity except at 2.0 kg/ha. The protein content of grain was higher in various herbicide treatments compared to the untreated control. Application of fluchloralin, pendimethalin and metolachlor each at 1.0 kg/ha has been found promising in enhancing the values of NAR at 45-60 and 60-75 DAS. Application of pendimethalin and metolachlor each at 2.0 kg/ha proved promising to record higher values of LAR at 45-60 and 60-75 DAS, but did not have any effect at the early stage (30-45 DAS).
