This study was conducted in the Lamto area to evaluate the effect of cocoa shell compost and chicken droppings compost on cassava agronomic variables. The main aim is to increase cassava production, which is in relative decline due to soil impoverishment through organic amendments. 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 droppings compost. The experimental design used for this study was a complete randomized block design with 3 replicates. The results showed that the two fertilizers used, being rich in mineral elements, improved the agronomic variables of cassava, superior to the control. This was reflected in a high number of stems per cutting (3.62). However, the chicken droppings 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 droppings compost compared with 12.77 t/ha for the control. Thus, compost and chicken droppings compost can be recommended to improve cassava productivity in Côte d'Ivoire.
