Abstract

This study was done to evaluate the seed yield of okra (Abelmoschus esculentus L.) plants managed with inorganic and organic fertilizers on sandy regosol. In this experiment, the inorganic and organic fertilizers were applied as basal applications and also recommended inorganic fertilizers as topdressing were applied at 30 days after planting to all experimental plots. The results revealed that number of mature fruits per plant, number of seeds per fruit and air dry weight of seeds per fruit were increased by 45.9%, 29.2% and 34.9% respectively in the selected treatment (mixture of 6 t/ha cow and 4 t/ha poultry manures) when compared to inorganic fertilizer as control treatment. The selected treatment gave remarkably (P<0.05) higher seed yield (1.18 t/ha) among tested treatments. Hence, combined use of organic fertilizers at optimum level was better than inorganic fertilizer as basal application for obtaining high seed yield of okra with less environmental pollution on sandy regosol.
