Abstract
This study using polybags was conducted for 10 weeks to evaluate the effects of different rate of chicken manure and NPK Green on okra growth, development and yield, and soil chemical parameters. Chicken manure was added to the planting medium a week before transplanting and at 5th week after sowing at the rates of 30 t ha�¹, 50 t ha�¹, and 70 t ha�¹• NPK Green was added to the planting medium in 4 split applications at the rates of 300 kg ha�¹, 500 kg ha�¹, and 700 kg ha�¹ respectively. The study was carried out in an open area using complete randomized design (CRD) with four replications. All data’s were analyzed using One-way ANOVA and Tukey's test was used for means separation. The results showed significant differences in growth, development, yield, leaf nutrient content, and soil chemical properties between the treatments. The highest growth was obtained from plants growth on soil fertilized with 70 t ha-1 of chicken manure (T3); plant height, leaf dry weight, stem dry weight and root dry weight increased by 125.5%, 400.0%, 618.6%, and 836.6% respectively compared to control (T7) treatment. Treatment T3 also resulted in the shortest number of days to first flowering (42.8 days). The study indicated that okra plant (10 WAS) did not flower or fruit when no fertilizer was applied (control). Treatment T3 showed the highest mean pod fresh weight (37.6 g), length (18.2 cm) and diameter (7 cm). In comparison to soil properties before planting, soil chemical properties fertilized with 70 t ha�¹ of chicken manure was the highest in values of pH, total organic C, N, P, and K increased by 32.1%, 86.7%, 300.0%, 283.3% and 713.0% respectively. The results of analysis showed that treatment T3 mean total N (5.5%), P (1.4%) and K (4.8%) leaf nutrient content was the highest compared to the control (T7) treatment. The study concludes that 70 t ha-1 of chicken manure application was the best treatment for okra growth, development, yield, leaf nutrient content and soil chemical properties.
