Abstract
Soil fertility depletion in small holder farm is the fundamental cause of declining per capital food production. This study was carried out to evaluate the performance of poultry manure (PM) and NPK 15-15-15 fertilizers on the growth and yield of okra ( Abelmochus esculentus ) in Ikorodu agro ecological zone, Lagos, Nigeria. The experiment was laid out in Randomized Complete Block Design (RCBD), replicated three times. Okra growth parameters were assessed taking data on plant height at 3, 6, and 9 WAS, number of leaves at 3 and 6 WAS, while yield performance was assessed at harvest (number of fruit, fruit weight). The result showed that application of PM significantly (P<0.05) enhance plant height growth, number of leaves at 6 and 9 weeks after sowing (WAS) and number of fruits; while the average weights of the fruits was significantly (P<0.05) influenced by NPK fertilizer compared to other treatments. Comparatively both PM and NPK fertilizer significantly increase the growth and yield of okra compared with the control. PM performed better than NPK fertilizer. Therefore, PM could be used as alternative source of plant nutrient in Ikorodu agro ecological zone for continuous and sustainable okra production on degraded soil.
