Effect of herbicides on increase in productivity of groundnut (Arachis hypogaea)

A field experiment was conducted during winter season of 1993-94 at Bhubaneshwar to assess the efficacy of herbicides an groundnut (Arachis hypogaea L.) and to compare their relative effect with that of hand-weeding. Fluchloralin as well as pendimethalin had better effect than hand-weeding in respect of most of the growth parameters. However, maximum augmentation in yield was obtained in fluchloralin (0.75 kg ai/ha) followed by pedimethalin and hand-weeding. The protein and oil yields were also found highest in fluchloralin treatment.
