The fertility of soil as well as the nutritional composition of the plants grown in the agricultural fields is improved both by the usage of organic fertilizers and inorganic fertilizers. Organic farming is considered as the oldest agricultural practice whereas inorganic fertilizers are developed to meet the global food demand. Organic fertilizers are ecofriendly with long term effect. Allium and its parts are included in the diet by almost all the people in the world. Allium possess antibacterial, antiviral, antifungal activities, antimutagenic and antidiabetic properties. In this present study the carbohydrate, protein, lipid content and minerals like iron, calcium, phosphorous were estimated and compared in the leaves of Allium cepa var aggregatum grown in organic and inorganic fertilizers. Qualitative phytochemical analysis was also carried out. The carbohydrate and protein content is found to be increased in the leaves supplied with organic fertilizer. The iron content is increased 6 times in leaves grown in organic fertilizer when compared to inorganic fertilizer. Calcium and phosphorus levels were also elevated in leaves grown in organic fertilizer. The experimental results of the study show that organic fertilizer produces higher nutritional values on leaves of Allium when compared with inorganic fertilizer.
