Abstract
This study was conducted in the Lamto area to evaluate the effect of cocoa shell compost and chicken dropping compost on cassava agronomic variables. The evaluation led to the monitoring of plant development until harvest by measuring some agronomic variables of growth and yield of four varieties of cassava, Alleda agba, Bonoua, Six mois and Yacé each grown on soil fertilized with cocoa shell compost or chicken dropping compost. The experimental design used for this study was a complete randomized block design with 3 replicates. The results revealed that both fertilizers used improved the agronomic variables of cassava. This was reflected in a high number of stems per cutting (3.62). However, the chicken dropping compost gave the best development in stem length for the Six mois variety (121.10 cm). The Bonoua variety gave the largest diameter stems (21.98 mm). This variety gave the highest number of leaves (59) and a wider span (109 cm) with wider (16.75 cm) and longer (17.96 cm) leaves. As for yields, the best was obtained with the Bonoua variety, respectively 27.13 t/ha and 35.26 t/ha with cocoa shell compost and chicken dropping compost. Thus, compost and chicken dropping compost can be recommended to improve cassava productivity in Côte d'Ivoire.
