Productivity of okra (Abelmoschus esculentus L. Moench) as Influence by NPK Fertilizer and poultry manure in Northern Sudan Savanna Region of Nigeria

Abstract

The aim of this research work was to evaluate the effect of different levels of NPK fertilizer (0, 40, 80 kg ha-1) and poultry manure (0, 4, 8 tons’ ha-1) on the productivity of okra plant. The experiment was laid out in a Randomized Complete Block Design (RCBD) and replicated three times. From the result of the experiment, it was shown that there was significant difference in days to 50% flowering by application 0-ton ha-1 of both NPK and poultry manure. The application of poultry manure and NPK 15:15:15 showed significant difference among the treatments to fruit length, fruit diameter, fruit yield in kgha-1 and weight of fruit in kgha-1 at various weeks of data collection. The increase in the level of poultry manure and NPK 15:15:15 fertilizer showed the significant effects on fruit length, fruit diameter, fruit yield ha-1, and weight of fruit in kgha-1. Some of the parameters were statistically at far by varied level of factors and time. Okra variety Clemson spineless significantly gave taller plants, longer fruits and fewer days to 50 % flowering. Both poultry manure and NPK fertilizer were found to be sufficient to increase the yield of okra plant.
