Backgroun: Sweet potato is an important food security crop in Nigeria. The crop as food product is a source of energy, proteins, pro-vitamin A (B-carotene), vitamin C and iron and rich in dry matter and non-carbohydrate macronutrient composition of the edible tuberous roots. Objective: The objective of this study was to assess the constraints mainly isolate and identify the causal organism causing soft rot of sweet potato and determine some control measures against the pathogens some animal droppings. Methods: A field trial was conducted at Michael Okpara University of Agriculture Umudike Experimental farms in 2017 cropping season to investigate the influence of different organic amendments on growth performance and disease incidence of three varieties of sweet potato (Ipomoea batatas)[L.] Lam) with regards to the best yield. This included use of compost manure consisting of Centrosema pubescens, Calapogonium muconoides, Panicum maximum, goat dung, rabbit dung, and poultry droppings at the rate of 400kg/ha. Data were collected on growth parameters and % disease incidence and severity. Results: Results obtained showed that animal droppings were superior to compost manure and untreated control especially poultry droppings proved most effective, and when three varieties were compared it was found that varieties Tis87/0078 was the best in terms of growth performance and tolerance to disease. Conclusion: This work therefore suggests application of poultry droppings a major means to improve yield and reduce wilt diseases and leaf spot in sweet potato farms in humid tropics of South Eastern Nigeria.
