Abstract

Weeds are a major biotic constraint in rice production, causing crop yield losses. Fertilization system may be an effective control of weeds. This study aims to improve rice productivity through soil amendment and weed management in Burkina Faso.
Method. The trial was set up in a Fisher block design with 4 replications and 10 fertilizer treatments. The effect of the fertilization was assessed on weeds at 45 days after planting through their abundance and dry biomass, and on rice through plant height and grain yield. weeds diversity at 65 days old has an average Shannon index of 2.9 bits. Three (03) weed clusters and their indicator species that are associated with the treatments studied were identified at 65 days after sowing. The Cyperus esculentus L. weed grouping was found to be associated with the organo-mineral fertilizer treatments. The application of poultry manure plus urea obtained simultaneously the lowest weed infestation rate (6.37 g/m²) and the highest grain yield (1.6 t/ha). Thus, to improve the productivity of upland rice, integrated weed management could be a combination of poultry manure treatments combined with mineral fertilization and specific control methods for the main species of the Cyperus esculentus L. group.
