  • Two field experiments were carried out to investigate effects of N.P.K (20:10:10) fertilizer on the growth and yield of yam minisetts in 2016 and 2017 cropping seasons at the Teaching and Research farm, Department of Agronomy, Cross River University of Technology. Obubra, Cross River State Nigeria. The experimental design was a randomized complete block design they were eight treatments namely 0, 5 0, 100, 150, 200, 250, 300 and 350 kg/ha NPK 20:10:10: fertilizer replicated four times. The results should that the application of NPK 20-10-10 fertilizer significantly (p<0.05) increased growth and yield of yam minisetts. The used of 350 kg/ha NPK 20:10:10: gave the highest number of leaves, branches per plant an10: fertilizer in commercial yam minisetts cultivation for optimum growth and tuber seedlings yield and reduce cost of planting materials in Obubra central, Cross River, Nigeria condition. Therefore, based on this research findings, 250-300kg/ha of NPK 20:10:10 fertilizer should be applied in the cultivation of yam minisetts for optimum growth and yield of seed yam tubers (planting materials) and is recommended to farmers to adopt for large scale production of seed yam tubers to be used as planting material.
