Abstract:
The present investigation entitled “Effect of Integrated Nutrient Management on quality of potato (Solanum tuberosum L.) cv. Kufri Chandramukhi under Southern Telangana Agroclimatic region” was carried out during Rabi season of 2021-22 at College of Horticulture, Sri Konda Laxman Telangana state horticultural university, Rajendranagar, Hyderabad. The experiment was laid out in Randomized Block Design (RBD) with nine treatments and three replications. Treatments consisted of T₁: Control (100% RDF), T₂: 50% RDF + Vermicompost (3 t ha^-1), T₃: 50% RDF + Biofertilizer (Azotobacter - 6.25 kg ha^-1), T₄: 50% RDF + Green leaf manure (3.75 t ha^-1), T₅: 50% RDF + Vermicompost (1.5 t ha^-1) + Biofertilizer (Azotobacter-3.125 kg ha^-1), T₆: 50% RDF + Vermicompost (1.5 t ha^-1) + Green leaf manure (1.875 t ha^-1), T₇: 50% RDF + Biofertilizer (Azotobacter-3.125 kg ha^-1) + Green leaf manure (1.875 t ha^-1), T₈: 25% RDF + Vermicompost (1.5 t ha^-1) + Biofertlizer (Azotobacter-3.125 kg ha^-1) + Green leaf manure (1.875 t ha^-1), T₉: 100% Organic Manures FYM (7.5 t ha^-1), Vermicompost (1.5 t ha^-1), Biofertilizer (Azotobacter-3.125 kg ha^-1), Green leaf manure (1.875 t ha^-1). Different integrated nutrient management treatments have a significant influence on the quality paramaters of potato. Highest starch content (23.19%), ascorbic acid (14.11 mg 100g fresh weight^-1), total sugars (0.57%) and reducing sugars (0.49%) was recorded when 50% of recommended dose of fertilizer (RDF) was applied in combination with vermicompost @ 1.5 t ha^-1 and Biofertilizer @ Azotobacter-3.125 kg ha^-1. TSS found to be non-significant.
