Abstract

The aim of this research was to evaluate the color, content in tomatoes that is lycopene.Lycopene is a carotenoid that has antioxidant properties and imparts the red pigment in some fruits and vegetables. It is a pigment principally responsible for the characteristic deep-red color of ripe tomato fruits and products.  In this research desi variety and hybrid variety of tomato plats were  treated with various fertilizers and  effect  of fertilizers on content of tomato was esimated.  Tomato paste prepared from tomato cultivated from Deulgaon Raja region  was dehydrated with methanol, then lycopene was extracted with methanol-carbon tetrachloride mixture. Pure lycopene was obtained by twice crystallization of crude product from benzene through addition of boiling methanol. Further purification was achieved using column chromatography with alumina as the adsorbent.  Average quantity of extracted pure lycopene was calculated as in desi variety, Lycopene content values for treatment of various fertilizers are Urea(5.2), Super phosphate(6.5), Potash(7.2), Cowdung(10.5), Polutry manure(12.5), Control(1.1) and in  hybrid variety Lycopene content values are Urea(5.3), Super phosphate(5.5), Potash(6.3), Cowdung(8.7), Polutry manure(11.5), Control(1.0). mg per 100 g tomato. It was observed that lycopene content in tomatoes treated with  polutery manure, cowdung have higher values and treatment with chemical fertilizers have lower values
