Studies on Controlled Release Fertilizer on Roselle and Amaranthus Plants

India needs to raise its food grains targets at a rate of more than 4 million tons per annum. Scope for increase in area under cultivation is negligible. Due to rapid increase of population as well as the drop in the average cultivable land required for farming. Plants require necessary nutrients like Nitrogen, Phosphorus and Potassium for their photosynthesis process the soil should have the capability of providing the essentials in abundant. In this study we are mainly concentrated on the growth of plant, pH, and salinity, amount of nitrogen percent, amount of potassium percent, amount of phosphorous percent present in the soil and how they are helpful to the plant growth and to study the type of effects of these parameters on plant growth.
