Plant height: Nutrients supplied in the form of NPK, OBF, PM, Gliricidia sepium alone, or in combination, affected okra plant height, stem circumference and leaf area (Table 2). Plants treated with OBF combined with NPK had the tallest plants. Poultry litter and Gliricidia leaves mixed with NPK produced plants with comparable heights. The unmixed OBF and PM had shorter plants that were similar in height. Plants treated only with NPK were shorter than plants treated with any of the organic materials mixed with NPK that were comparable with each other. Plants from the control had significantly shorter plants than from any of the fertilizer types.
