Abstract: Agriculture has most demanding and advancement factor in marketing. Fertilizers contain one or more of these essential plant nutrients. Nitrogen, Phosphate, and Potassium are the major nutrients supplied by chemical fertilizers. Nitrogen promotes plant growth and development. Plants look green and the growth will be lushful .It helps increasing crop yields. At higher levels nitrogen causes a loss of certain plant species, depletion of soil nutrients, death of fish and aquatic organisms, and contamination of drinking water. The supply and demand for nitrogen is discussed relative importance of fertilizer and fixed nitrogen. The main purpose of this paper is to discuss supply and demand of nitrogen fertilizer in Andhra Pradesh. The overview of the state is discussed..
