Studies on the Effect of Integrated Nutrient Management (INM) on Growth and Yield Parameters of Carrot (Daucas carota L.) cv. Kuroda Improved under Southern Telangana Conditions

A field experiment was conducted during rabi 2017-2018 at Vegetable Research Block, College of Horticulture – Mojerla, SKLTS Horticultural University, Hyderabad, Telangana, India, to study the effect of integrated nutrient management (INM) on growth and yield parameters of carrot (Daucas carota L.) cv. Kuroda improved. The experiment was carried out with the nine integrated nutrient management treatments i.e. T1 - RDF (NPK @ 50:40:50 kg/ha), T2 - FYM 12 t/ha, T3 - Vermicompost @ 6 t/ha, T4-- Rhizosphere Bacteria (AZB + PSB each @ 7 kg/ha), T5 - 50 % RDF + 50 % FYM @ 6 t/ha, T6 - 50 % RDF + 50 % Vermicompost @ 3 t/ha, T7 - 50 % RDF + 50 % Rhizosphere Bacteria, T8 - 25 % RDF + 50 % FYM @ 6 t/ha + 50%Vermicompost @ 3 t/ha, T9 - 25 % RDF + 50 % FYM @ 6 t/ha + 50 % Vermicompost @ 3 t/ha + 50 % Rhizosphere Bacteria, in Randomized Block Design and replicated thrice. Among the treatments, T9 (25 % RDF + 50 % FYM @ 6 t/ha + 50 % Vermicompost @ 3 t/ha + 50 % Rhizosphere Bacteria) registered significantly higher plant height (53.50 cm), more number of leaves per plant (16.40), maximum leaf length (38.20 cm) and fresh weight of leaves (62.46 g), least number of days taken to harvest (75.33 days), maximum root length (19.76 cm), root diameter (3.96 cm), fresh weight of root (81.33 g), root yield per plot (5.60 kg) and root yield per hectare (18.60 t).
