Three different heights of prevailing wind: 0 m, 1 m and 2 m and two organic treatments (poultry manure, PM and rice bran, RB) were used. Organic treatments were divided into eight, namely 5 tons/ha RB (RB5), 10 tons/ha RB (RB10), 5 tons/ha PM (PM5), 10 tons/ha PM (PM10), 5 tons/ha each of RB and PM (RB5PM5); 10 tons/ha RB and 5 tons/ha PM (RB10PM5); 5 tons/ha RB and 10 tons/ha PM (RB5PM10), 10 tons/ha RB and 10 tons/ha PM (RB10PM10) at 3 × 2 × 6 × 3 factorial with control experiment. Measured were plant height, number of leaves, number of branches, stem girth. Results revealed that RB5PM10 yielded tallest plant (27.5 ± 8.15 cm), high number of leaves (15.75); highest leaf area (397.50 ± 18.22 cm²); stem girth (1.70 ± 6.25 cm), all at 1 m wind height, respectively translating to 48.64, 0.01, 47.22 and 21.43% more than their corresponding values in control experiment. Application of RB and PM in ratio 1:2 respectively to soil enhanced all yield components and vegetative development provided heights of okra are maintained at 1 m from soil surface for winds’ effectiveness.
