Effect of Integrated Nutrient Management on Growth and Yield of Tomato (Solanum lycopersicum L.) var. Arka Rakshak

Abstract

Investigation was carried out to study the effect integrated nutrient management in tomato (Solanum lycopersicum L.) var. Arka Rakshak during 2014-15 at the Division of Horticulture, University of Agricultural Sciences, Gandhi Krishi Viganana Kendra, Bengaluru. The experiment comprised of fifteen different treatment combinations of inorganic fertilizers (RDF) and biofertilizers (VAM, PSB and Azatobacter) were tried in randomized complete block design (RCBD) with three replications. The growth parameters of tomato plants such as plant height (108.60, 113.50 and 122.36 cm) number of branches (12.00, 15.20 and 18.30) and leaf area ((68.53 cm2) were recorded maximum in the treatment received 75 per cent RDF (Recommended Dose of Fertilizers) + Azotobacter + Phosphorus Solubilizing Bacterium [PSB] + VAM (Vascular Arbescular Mychorriza) at 45, 90 and 135 Days After Transplanting respectively. Plant supplied with 75 per cent RDF + Azotobacter + Phosphorus Solubilizing Bacterium [PSB] + VAM recorded maximum fruit weight (69.70 g), number of fruits per plant (80.00), fruit length (7.15 cm), fruit diameter (5.88 cm), fruit yield /plot (7.50 kg/plot) and total yield / ha (112.50 tons/ha) while, minimum fruit and yield attributing parameters were recorded in plants supplied with RDF alone (Control).
