This study investigated the growth and yield response of Okra (<em>Abelmoscus esculentus</em>) to the method and time of poultry manure application, in order to match the time of optimum nutrient release with nutrient uptake by the okra plants. A randomized complete block design with 6 treatments and 3 replicates was used for this study. The poultry manure was applied at three different times: During planting (0-DOP), 2 weeks after planting (2-WAP) and 4 weeks after planting (4-WAP) using two application methods: surface-broadcasting and plow-incorporation. Results showed significant differences in method and time of application of poultry manure. The application of poultry manure, using plow-incorporation method on the day of planting (0-DOPI), significantly improved growth and yield (5.88 t ha<sup>-1</sup>) of okra. Also, 0-DOPI treatment took fewer days to attain 50% flowering (55 days) and fruit setting (58 days). This indicated that the match between nutrient demand and supply was most evident under 0-DOPI treatment. However, the surface broadcasting method at 2-WAP and 4-WAP, could not match release and supply of nutrients with critical developmental stages of okra.  Hence, poultry manure incorporation at time of planting could improve okra production in the study area.</p>}, number={1}, journal={RENEWABLE}, author={Mornya, P.
