The use of organic addition has been found to be an environmentally beneficial method for enhancing quality of crops with good soil quality. Similarly, selection of suitable irrigation period is an important factor for optimum crop production. A study was conducted to evaluate the effects of chicken manure and irrigation interval on the development and production of okra in a greenhouse. The poultry manure was applied to 5 kg soil at three different rates, namely: 20 t ha-1 (T1), 40 t ha-1 (T2), and 60 t ha-1 (T3), and the fourth group without poultry manure treatment were set up as the control. Four levels of irrigation intervals (3, 6, 9 and 12 days) were selected for the study. Plant height, number of leaves, leaf area (cm2), and stem diameter were all assessed as growth metrics. Leaf fresh weight, leaf dry weight, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, and total plant dry weight were the yield characteristics that were measured. The findings indicated that increasing poultry manure rates enhanced the examined growth and yield parameters, but increasing irrigation intervals decreased the studied growth and yield characteristics of Abelmoschus esculentus. The interplay between chicken manure and irrigation intervals, on the other hand, had no significant effect on leaf area and stem diameter. Finally, the application of 60 t ha-1 poultry manure and a three-day watering interval boosted the development of Abelmoschus esculentus.
