ABSTRACT = {The experiment was conducted at the teaching and Research farm of the 
Federal University Wukari Taraba State, Nigeria to assess, evaluate and 
compare the effect of organic fertilizers such as poultry manure, cow 
dung, organic manure and in-organic fertilizers such as NPK and urea on 
the growth and tuber yield of sweet potato. The recommended rates of cow
 dung (10t/ha) poultry manure (10t/ha), organic manure (10t/ha) 
NPK15:15:15 (400kg/ha) and urea (200kgN/ha) were applied as treatment to
 sweet potato with a control at (0kg/ha). These were arranged in a 
randomized complete block design with three replications. Measurement 
were taken on the growth and tuber yield at harvest such as the length 
of primary vein, number of secondary vein number of leaves, number of 
tuber and tuber weight. Data collected were analyzed using (ANOVA) and 
the significant means separated using Duncan multiple difference at 5% 
probability level. The result revealed or showed that numbers of leaves 
were significant in all the treatments. Application of urea fertilizer 
produced the highest number of tuber per plant, while tuber weight was 
not significantly different, but poultry manure application had the 
higher mean value of (2.34kg). It was concluding that application of 
poultry manure as organic fertilizer are better and can compare readily 
with inorganic fertilizer (urea) in the production of sweet potato.},
