In developing countries like India, agriculture is the most important factor which influence the economic development of country. Due to constant increase in population, demands of agricultural goods and adequate amount of food availability is also increased. To overcome food scarcity a large amount of chemicals is annually applied at the agricultural soils as fertilizers. Such applications may result in the increase the level of heavy metals. In this study we will use okra plant for find out impacts of chemical fertilizers on soil of Kota region in larger quantity than recommended dose. We will measure the pH, EC and CEC of soil and EC and pH of water and also measure nutrient levels of NPK in soil before plantation. Then we will sow different varieties of okra seeds and use specific doses of NPK for okra yield. Aim of this study is reveal the effect of different NPK singly and in combination on the crop. And also find out the effects of chemical fertilizer in different proportions on the vegetative properties of okra plant and to check the soil quality and fertility. Fertilizers can change soil structure and soil fertility. In addition, toxic substances may accumulate within vegetables and causing negative effects in human and animals are fed.
