The study was conducted to observe the comparative effect of different organic fertilizers (cowdung, vermicompost), inorganic fertilizer (DAP) and biofertilizer on the biochemical characteristics of leaf of groundnut legume plant. The study was conducted at University of Rajasthan Jaipur. Five types of treatments were conducted to analyse Arachis hypogaea L. plant. T1- Control plant (Without any fertilizer), T2- DAP treated plant, T3- Cow-dung treated plant, T4-Vermicompost treated plant and T5-Biofertilizer treated plant. Biochemical parameters of leaf analyzed were viz. total soluble sugar, starch, protein, total lipid, total phenol, ascorbic acid, chlorophyll a, chlorophyll b, total chlorophyll, carotenoids and activity of antioxidant enzymes like peroxidase and catalase. Results of experiment revealed that chlorophyll a (0.99±0.01 mg/gm), chlorophyll b (0.37±0.02 mg/gm), total chlorophyll (1.36±0.03 mg/gm), protein (240.67±7.57 mg/gm), total soluble sugar (6.56±0.18 mg/gm), starch (8.971±0.32 mg/gm), total phenol (1.66±0.06 mg/gm), antioxidant enzyme catalase activity (1.80±0.26 µml/l/g/fw) and total lipid content (15.33±0.15 mg/gm) were significantly influenced with vermicompost application (T4) as compared to other treatments and control. Carotenoids (0.52±0.00 mg/gm) with DAP treatment (T2), ascorbic acid (14.25±0.19) with cowdung treatment (T3) and peroxidase activity (2.63±0.45 µml/l/g/fw) with rhizobium biofertilizer treatment (T5) were influenced significantly as compared to other treatments and control. The work concluded that quality and quantity of food for growing world population requires sustainable management of fertilizers and new technology.
