Important findings from the investigation are, summarised below :- Yield attributes such as length and girth of cob, number of grains per cob and 1000-grain weight were significantly influenced by pre-emergence application of the full dose, irrespective of the weedicides. However, among the weedicides, Tafazine 50 W (Simazine) proved to be the best Maximum grain and stover yields were obtained with full dose pre-emergence application of Tafazine 50 W (Simazine). In almost all the characters two hand. weeding was superior to one hand weeding.
