Influence of Different Organic Fertilizers and Urea on Biochemical Constituents of Tomato (Lycopersicon esculentum) Fruits

The tomato (Lycopersicon esculentum) plants were grown in soil supplemented with organic fertilizers (composted cowdung (CD), green neem leaves (NL), sugarcane bagasse(SB) and wheat straw (WS) and chemical fertilizer (urea). The fruits developed on treated plants were analysed for vitamin C, antioxidant activity, protein content, sugar content and titratable acidity. The vitamin C content and antioxidant activity is found more in fruits of compost treated plants compared to fruits of chemical fertilizer treatment. The protein content is found higher in fruit of urea (chemical fertilizer) treated plant, followed by NL compost treatment. The reducing sugar content is found more in fruits of WS and titratable acidity in fruits of CD compost treatment compared to other treatments.
