Optimizing Growth and Yield of Okra (Abelmoschus esculentus) through Varied Nitrogen Fertilizers

Abstract

This research investigates the efficacy of different nitrogen fertilizers—urea, ammonium nitrate, potassium nitrate, calcium nitrate, and a control with no fertilizer—on optimizing the growth and yield of okra (Abelmoschus esculentus). Conducted under controlled conditions, the study assesses key growth parameters such as plant height, leaf area, flowering patterns, and fruit development. Each nitrogen fertilizer treatment is meticulously applied at recommended rates during specific growth stages to evaluate their individual impacts on okra physiology. Preliminary findings reveal nuanced variations in growth patterns among the different nitrogen fertilizer treatments. Urea, known for its high nitrogen content, demonstrates a notable influence on vegetative growth, while ammonium nitrate exhibits distinct effects on flowering dynamics. Potassium nitrate and calcium nitrate, with their unique nutrient profiles, contribute to specific aspects of fruit development. The control treatment provides a baseline for comparison, enabling a comprehensive evaluation of the botanical potential inherent in each nitrogen fertilizer. This study not only contributes to the understanding of nitrogen fertilizer impacts on okra growth but also has practical implications for sustainable agricultural practices. The results aim to guide farmers in the selection and application of nitrogen fertilizers tailored to optimize okra yield while minimizing environmental impact. The findings underscore the importance of targeted nutrient management in enhancing crop productivity and advancing sustainable approaches in modern agriculture.
