In developing countries such as India, agriculture remains the most critical factor influencing national economic development. With the constant increase in population, the demand for agricultural products and the need for adequate food availability have also risen significantly. To address food scarcity, farmers often apply large quantities of chemical fertilizers to agricultural soils, frequently exceeding the recommended doses. Such practices can lead to the accumulation of heavy metals and other adverse effects on soil and crop health. In the present study, okra (Abelmoschus esculentus L.) has been selected as the test crop to evaluate the impacts of chemical fertilizers on different varieties cultivated in the Kota region. The experimental design will involve the application of nitrogen (N), phosphorus (P), and potassium (K) fertilizers, both individually and in various combinations, at higher-than-recommended levels. Prior to sowing, soil samples will be analyzed to determine pH, electrical conductivity (EC), cation exchange capacity (CEC), and nutrient levels (NPK). Water samples will also be tested for pH and EC. After sowing different okra varieties, specific fertilizer doses will be administered, and their influence on crop yield and vegetative growth parameters will be assessed. The primary aim of this study is to investigate how varying proportions of NPK fertilizers affect “Vegetative and yield characteristics of okra plants.” Furthermore, the study seeks to identify potential risks associated with the overuse of chemical fertilizers, including the accumulation of toxic substances in vegetables, which may ultimately pose health hazards to both humans and animals consuming them.
