Abstract

A research study on the response of different sweet potato cultivars to different levels of NPK 15:15:15 in Igbariam Anambra State, Nigeria was was conducted between May and July 2018 at the teaching and research farm of the Department of Crop Science And Horticulture, Faculty of Agriculture, Chukwuemeka Odumegwu Ojukwu University (COOU) Igbariam Anambra state.It was a factorial experiment laid out in Randomized Complete Block Design (RCBD) with four replications. Three varieties of Sweet Potato viz; TIS 87/0087, Umuspo 1 and Umuspo 3 were planted. Four fertilizer treatments NPK 15:15:15 at 200kg/ha 300kg/ha 400kg/ha 0kg/ha were applied four weeks after planting. Data was collected at 2 weeks’ interval on growth parameters and yield parameters. Analysis of variance was used to know the significant effect of blocking and treatment on various parameters evaluated and separation of treatment means was done using Fisher’s least significant difference. Sweet potato variety Umuspo 1 was found to produce significantly (P<0.05) large number of leaves and was well established compared to other varieties. Umuspo 3 and Tis87/0087 produced longer vine than Umusopo 1. Generally, increase in fertilizer rate resulted in increase in vegetative growth. TIS87/0087 was best in the overall yield performance when compared to other cultivars. Therefore, NPK 15:15:15 at the rate of 300kg/ha can be recommended for the production of TIS/87/0087 in the study area, further breeding work is also recommended.
