Abstract
A study was conducted in 2009 at the Teaching and Research Farm of the Department of Agronomy, Delta State University, Asaba Campus with the aim of evaluating the effects of time of planting of sweet potato for the control of weeds in maize. The treatments were planting of sweet potato and maize on the same day, planting of sweet potato two weeks before maize planting sweet potato two weeks after maize and planting of sole maize. Generally, the results showed that the performance of maize (planted two weeks before sweet potato) in terms of plant height, leaf area, number of leaves, days to 50% taselling, number of grains / cob, number of rows/cob, 1000 grain weight and dry grain yield/plot was significantly higher compared to the other treatment (planting of sweet potato two weeks before maize planting sweet potato two weeks after maize and planting of sole maize) hence planting of sweet potato two weeks before maize should be recommended to farmers in Asaba agro ecological zone and its environs.
