Sumario:This study was carried out to investigate the leaf and root yield response to leaf harvest and the application of NPK fertilizer, compost and the combination of NPK plus compost of three improved cassava varieties. The experiment was a complete randomised split-split plot design with three factors and three replications. Leaf harvest was at 3 months and 5 months after planting (MAP). The final root harvest was at 12 MAP. The leaf dry matter yield was not significantly (p> 0.05) different between varieties and fertilizer treatments. The average leaf yield was 1454.19 kg/ha DM in control. Leaf yield increased by 10.42% when compost was applied, by 39.91% when compost plus NPK was applied and by 34.19% when only NPK was applied. Root yield was significantly (p˂0.05) affected by cassava variety and leaf harvest. Average root DM yield losses were 3.86 t/ha (45.77%) when leaves were harvested. Root DM yield loss was compensated to 35.59% (1.64 t/ha) when compost plus NPK fertilizer was applied and 24.05% (1.11 t/ha) when NPK was applied. Two varieties responded positively to fertilisers and were able to compensate for root yield losses. IITA-TMS-IBA071393 appears a suitable candidate for cassava farmers with small income because it did not require inputs.
