There is a shift towards organic fertilizers as a result of high-priced inorganic fertilizers. The paper evaluates the effects of organic fertilizers on the growth, yield and nutritional status of spinach. The experiment was laid out in a Randomized Complete Block Design (RCBD) with six treatments and three replications. The treatments were T1 (No manure/fertilizer), T2 (cow dung), T3 (goat and sheep manure), T4 (poultry droppings, T5 (rabbits droppings) and T6 (NPK 15:15:15) respectively. Manures application (15t/ha) were done before nursery, after transplanting and two weeks after transplanting. Amongst the various organic manures, poultry manure produced significantly higher (p<0.5) plant growth, yield (18.2t/ha) and proximate composition. Therefore, planting spinach with poultry manure under moderate rainfall enhances the growth and yield of spinach.
