Abstract: 
Three methods of weed controljembe, atrazine and jembe plus atrazine were studied to examine the effects of weeds on soil moisture, soil aeration and soil temperature. Weeds in a crop of maize during the early growth stages caused a large decrease both in the rate of dry matter production and total dry matter at tasselling. Effect of weeds on vegetative growth was reflected in (i) the number of potential grain sites initiated, (ii) the final number of cobs per plant (iii) the final number of grains per plant, (iv) the 1,000 grain weight and (v) the grain yield. Soil moisture and aeration studies showed that both parameters were adversely affected by presence of weeds, but there were no large differences in vegetative growth in the final year. No significant differences were recorded in the final grain yield between the three methods used.
