Effects of Poultry Manure and NPK Fertilizers on Growth and Yield of Okra Plant

Abstract

Okara has gained more importance in every community on the globe due to its nutritional value. This study examined the effect of organic and inorganic fertilizers on the growth and yield and of okra on the on farm level. Organic form of fertilizer used was poultry manure and while the inorganic was NPK fertilizer. The experiment was laid out in a Randomized Complete Block Design during the raining seasons of 2019. Four treatments with three replications were used. Treatments are arranged as control T1 (Without fertilizer + No Poultry Manure + No compost), T2 (NPK full dose (150 kg ha-1N, 75 kg ha-1P and 60 kg ha-1K), T3 (full dose of poultry manure (PM) 30 ton ha-1), T4 (50% NPK+50% Poultry Manure). Plants growth and yield parameters were determined like the total number of leaves per plant, plant height, the total number of fruits per plant, fruit yield and total yield increase. No significant increase was observed in the yield and growth of okra under control and full NPK fertilizer treatment. Application of poultry manure as well as its mixture with full NPK considerably increased the growth and total yield attributes of Okra. The joint use of 50% NPK+50% PM also showed the most significant effect on okra growth and yield of the crop.
