Abstract

The rice/cassava rotation is one of the dominant rice-based cropping systems in western Côte d'Ivoire due to the inaccessibility of chemical fertilisers. The low productivity of this cropping system makes it necessary to think about improving agronomic performance. The objective of this study is to determine the rice precedent effect on the cassava production . To achieve this objective, an agronomic trial was set up at the CNRA Research Station in Man on a Ferralsol. Five cropping sequences were compared in a Fischer block design with 5 treatments and 4 replications: 2 intensive monocultures of rice (0.20 m × 0.20 m) and cassava (1 m × 1 m) and 3 alternations of rice and cassava (R/M/R M/R/M and R/R/M (farmer control)). The parameters measured were height, tillering, and yield of rice and cassava, as well as soil chemical parameters. The results showed that rice crop is a good previous crop for cassava production, while cassava crop had no significant effect on rice production. The rice/cassava rotation harmed soil chemical parameters. Except for the improvement of nitrogen and phosphorus contents due to analysis error and the mobility of nutrients along the fertility gradient. Finally, M/R/M was found to be the best cropping sequence in a cassava-based cropping system.
