Maize (Zea mays), which is the third most important cereal crop of the world, is an important dual purpose crop used in human diet and animal feed. The experiment was conducted to investigate the effect of weeds on the growth and yield of maize, and to determine the best time and frequency of weeding to get an optimum yield. The experiment was conducted at Teaching and Research Farm of The College of Education, Lanlate in the cropping season of 2016. There were four treatments replicated four times to make the total number of plot to be sixteen (16). The treatments are; No weeding, weeding after 2, 3 and 4 weeks. It was shown that if the first weeding is done between 3weeks and 2weeks after planting the optimum yield will be obtained. When the first weeding is allowed to reach 4weeks before it is done there is a drastically reduction in the crop. A crop failure with absolutely low yield was obtained in a field where weeding was not done at all.
