Abstract
An experiment was conducted for two seasons to determine the effects of weed control methods on maize yield and net income of small-holder farmers. Weed control was by (1) application of the herbicide primextra (2-chloro-4-ethylamino-6-isopropylamino-l, 3, 5-triazine, and 2-chloro-6-ethyl N-(2-methoxy-l-methylethyl) acet-o-toluidide), (2) three hoe weedings and (3) an integration of various intercrops with one hoe weeding. All control methods reduced weed weight and increased maize yield significantly. Generally, primextra was the most effective. Highest net income was achieved with maize and sweet potato (weeded once). Next was maize and groundnut (weeded once). The use of either of these intercrops as a smother crop is recommended for small-holder farmers in the rainforest zone of Nigeria.
