Nitrogen is essential for the plant right from sowing to the growth and development of the plant. Increases the vegetation of the crop, size of the leaves increases which enhances the photosynthetic activity of the plant. Increases the fruit growth and production of seeds. Plant metabolism, chlorophyll content, Nucleic acid and proteins, carbohydrates formation and photosynthesis occur by the presence of nitrogen. Excess application of nitrogen increases the vegetative growth which prevents fruit growth due to overcrowding
