Effect of Organic Manures and Biofertilizers on Growth, yield and Quality Traits of Tomato (Solanum lycopersicum Mill.) cv. Roma

A field study was conducted at Horticulture research farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow during Rabi season of 2014-15 to study the effect of organic manures and bio-fertilizers on growth, yield and quality traits of tomato cv. Roma. The seedlings were transplanted in last week of October with a spacing 60cm x 45cm. The experiment was laid out in Randomized Block Design with twelve treatments replicated thrice. Result indicated that the maximum height of the plant (21.95, 33.91 and 45.15cm) was recorded at 30, 60 and 90 DAT with 50% RDF+ 50% VC+ PSB application followed by 50% RDF+ 50% VC+ Azosporillum and minimum in control. The number of branches (4.13, 10.09 and 16.03) was recorded at 30, 60 and 90 DAT with the application of 50% RDF+ 50% VC+ Azosporillum, followed by 50% RDF+ 50% VC+PSB and minimum in control. The number of days taken by plants for flowering was less under control (41.52). The maximum number of flowers, flower clusters and fruits/plant were 31.93, 9.09 and 18.00 respectively in 50% RDF+ 50% VC+ Azosporillum. Similarly maximum fruit weight (70.94 gm) and fruit diameter (7.06 cm) were also noticed with the application of 50% RDF+50% VC+ Azosporillum which is significantly superior over control. Same trend was also noticed in yield per plant (0.991 kg), per plot (15.87 kg) and per ha (73.33q) in the same treatment. The maximum titrable acidity 0.72 was in control among fruits of different treatments while minimum titrable acidity (0.56) was found in fruits of treatment received 50% RDF+ 50% FYM+ Azosporillum. The maximum TSS (5.400B) obtained from the fruits given 100% Vermicompost and minimum in control (3.650Brix). Highest vitamin C of fruits has been recorded in the 50% RDF+ 50% VC+ Azosporillum (23.90%) as compared to the control (21.71%).
