Abstract
Different cropping patterns resulted in different weed populations. In the 1st crop Amaranthus spinosus dominated the weed flora in all plots. In the 2nd crop there were dramatic changes in the weed flora; in patterns with rice as the first crop Ipomoea triloba dominated, while A. spinosus dominated in the other patterns. Rottboellia exaltata was important when sorghum was in the cropping pattern. The amount of weeding required for opt. yield varied between crops and seasons. Yield losses due to weeds were higher in rice-based than in maize- or sorghum-based cropping patterns.
