Abstract

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.

Summary

Introduction

Okra (Abelmoschus esculentus (L.) Moench) is a tropical and subtropical annual vegetable that belongs to the Malvaceae family. In addition to being a highly nutritious vegetable, okra has medicinal properties. Many minerals, such as phosphorus, potassium, and sulfur, as well as vitamins A and B can be found in it, along with vitamin C. Okra produces fruits for an extended period of time, necessitating a steady supply of plant nutrients, both macro and micro, for higher yields and better quality. For harnessing the higher yields and better quality, adequate quantities of plant. Water stress is one of the most significant constraints to crop production, and it is becoming a more serious issue in many parts of the world (Passioura, 2007). Agricultural, communities, industry, nature, becomes more intense, with agriculture bearing the brunt of the
