Increasing prices of fertilizer have made farmers turn to other sources of plant nutrients for crop

cultivation. Farmers are now increasing the use of animal manure to improve soil fertility. It is

not clear what ef ects these manures might have on the yield performance of sweet potato

(Ipomoea batatas). This study was conducted during the late raining season of the year 2016 at

Kogi State University Research/Student Demonstration Farm, in the Southern Guinea savannah

agro-ecological zone of Nigeria. The objective of this field experiment was to determine the

ef ects of dif erent levels organic manure (poultry manure (PM)) on the physical and chemical

properties of soil and yield of sweet potato (Ipomoea batatas). Five treatments were assessed in

a randomized complete block design, and replicated four times. The treatments include: T0 (0t/ha

PM), T1 (1 t/ha PM), T2 (2 t/ha PM), T3 (3 t/ha PM), T4 (4 t/ha PM) and T5 (5 t/ha PM). The soil

properties considered were; soil pH, organic carbon, ef ective cation exchange capacity, total

nitrogen and available phosphorus. Number of vines, length of vine and leaves per plant were

among the growth parameter evaluated for the growth performance of the test crop. Tuber

weight yield was the yield parameter considered for evaluating the sweet potato yield

performance. Result obtained indicated that the lowest total tuber yield (8.19 t/ha) was obtained

in plants fertilized with 0 t/ha of poultry manure. While the highest total tuber yield (11.7 t/ha)

was produced by plants treated with 4 t/ha poultry manure. A decline in total tuber yield (10.22

t/ha) was observed in plants fertilized with 5 t/ha of poultry manure, indicating that increase in

poultry manure could be associated with reduced total tuber yields. The result therefore

emphasized that 4 t/ha of poultry manure is the best for better sweet potato yield.
