Abstract
Soil fertility constraint is one of the factors hindering high productivity of okra (Abelmoschus esculentus L. Moench) in South Western Nigeria. Majority of these soils are deficient in nitrogen and phosphorus as a result of progressive loss in organic matter due to intensive cultivation and climatic conditions. Field trial was conducted to assess the effects of organic fertilizer sources on growth and yield of two varieties of okra at the Teaching and Research Farm, Ekiti State University, Ado-Ekiti. Treatments consisted of cow dung (CD), municipal solid waste (MSW), poultry manure (PM) at 15t/ha each, NPK 15-15-15 fertilizer applied at 150kg/ha and no fertilizer (NF) as control as well as two varieties of okra (V-35 and NHAe47-4). The experiment was laid out in a randomized complete block design (RCBD) in three replicates. Top soil (0-15cm) samples were collected before and after the trial for analysis. Data were collected on the following parameters; plant height, number of leaves, leaf area, number of pod plant-1, pod length and pod yield. The result revealed that PM significantly (P<0.05) gave the tallest plant (89.6cm), highest number of leaves (14.9), leaf area (444cm2) and number of pod (6.3) which are 102, 114, 49 and 75% more than control respectively. Application of PM significantly gave maximum pod yield (4531kg/ha) with clemson spineless NHAe47-4 and (2930kg/ha) in V-35 variety with total mean value of 3591 kg/ha which is 96% more than the control. Organic manure increased soil N, P, K but Ca was decreased with NPK application while Mg was decreased in MSW and NPK application. The results are suggestive that PM has the highest potentials as amendment. It therefore suggest that it can be a useful management strategy for sustainable fertility maintenance leading to minimize leaching losses, improve soil structure, and reduce input cost by reducing the use of inorganic fertilizer.
Keywords: Organic fertilizer, municipal waste, okra, varieties, NPK fertilizer.
