摘要

Among the various factors responsible for deplorably low yield of groundnut, severe weed infestation is important particularly in hot and humid climate of Indian sub-tropics. This crop is extensively grown as a rainfed crop during kharif season in India. It is generally sown at the onset of monsoon or just before the onset on monsoon. Initial slow growth combined with prostate nature of its growth and hot humid climate prevailing during the kharif season permit early and severe crop weed competition resulting in loss of yield to the tune of 35 to 80 percent (Varaprasad and Shanti, 1993; Murthy et al., 1994). Very little attention has so far been given on improving the weed management in groundnut field particularly under hot and humid conditions of West Bengal. The present investigation was, therefore, undertaken to find out an efficient weed management system in groundnut field for increasing the productivity of this crop.
