Critical period of weed competition with the growth of mungbean.

Muhammad Naeem and Saeed Ahmad

Abstract:
Although plant height was the maximum in weed-free plots, but differences were non-significant among plots having competition up to 30 days after emergence of mungbean. Weed competition with mungbean beyond 30 days after emergence was critical and resulted in considerable reduction in pod length. Maximum biological yield was produced in plots maintained weed-free throughout the growing season. Minimum biological yield was recorded from plots where weed competition prolonged up to 50 days after crop emergence and also up to harvesting of mungbean. Weed competition with mungbean persisting for 20-30 days after crop emergence was very critical and prolonged competition resulted in substantial yield reduction.
