3. INFLUENCE OF ORGANIC, INORGANIC AND BIOFERTILIZERS ON QUALITY CHARACTERS OF TOMATO FRUITS by GOLDI JAIN1, K.N. NAGAICH1, K.V. SINGH AND V.B. SINGH3
Organic farming is a production system which avoids or largely excludes the use of synthetically produced fertilizers, pesticides, growth regulators and livestock feed additives. Due to escalating cost of chemical fertilizers and objective of minimizing environmental pollution, the search of alternative source of plant nutrients is imperative. The present investigation was conducted during Rabi season 2015-16 and 2016-17 in the experimental field of Department of Horticulture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya (RVSKVV), College of Agriculture, Gwalior (M.P.). Amongst the combined application of organic and inorganic nutrients, T11 continued to be the best with respect to quality also. The highest pooled mean of total soluble solids (6.10 °Brix), ascorbic acid content (28.22 mg/100g of pulp), number of locules per fruit (6.50) and pericarp thickness of fruit (68.15 mm) were from the fertility treatment T11. The second best fertility treatment was T10 50 %NPK (60:30:40 kg/ha) and 50% FYM (12ton/ha) along with Azospirillium (2 kg/ha)). T1 (control) was found to have least number of (3.00) among all the treatments. On the other hand, the cumulative functions of applied nutrients played unique differential role in metabolism which provided conductive conditions for better utilization of photosynthates towards qualitative changes in tomato.
