A field experiment was carried out from March, 2017 to November, 2018 at the Federal College of Forestry, demonstration farm to determine the efficacy of poultry droppings and Npk fertilizer on the growth and yield of Cassava (Manihot esculenta). The study comprises of four treatments (poultry droppings, Npk fertilizer, Poultry droppings + Npk fertilizer and Control). These treatments were arranged in a Randomized Complete Block Design (RCBD) replicated four times. The combine application of poultry droppings and Npk fertilizer produced the highest (170.00cm), number of branches (2.00), leaf area (795.12cm2), stem girth (8.45cm), canopy spread (281.00cm), number of tubers (7.5), and larger diameter tubers (57.00mm)and produce the highest yield. The growth and yield of cassava was affected by the application of poultry droppings and Npk fertilizer. The combine application of PD + Npk fertilizer was found to increase the growth and yield characteristics of cassava than the single application of poultry and Npk fertilizer and the control (no application). This could be as a result of the increase in nutrient to the soil which improves its fertility. Thus, the use of a combination of poultry droppings and Npk fertilizer is recommended for the growers of cassava in the study area. Further research should be undertaken on the levels of both poultry droppings and Npk fertilizer for optimum productivity.
