Abstract
Aim: To study the effect of integrated nutrient management in growth of potato.
Study Design: The experiment was laid out in RBD with 13 treatments and replicated thrice.
Place and Duration of Study: The present investigation was carried out at Sri Konda Laxman Telangana State Horticultural University, Mulugu, Siddipet district, Telangana during the rabi, 2021-22 and rabi, 2022-23.
Results: Among the treatments, T12 treatment (75 % Recommended dose of NPK+ Organic NPK with micronutrients + Organic NPK + Organic based micronutrients + Organic phosphorus + Organic potash) was recorded significantly highest growth parameters like plant height (53.10 cm and 71.74 cm), leaf length (24.09 cm and 25.74 cm), leaf width (16.29 cm and 21.03 cm), leaf area (119.40 cm2 and 157.41 cm2), leaf area index (0.133 and 0.175), plant spreading (52.00 cm at E-W & 49.85 cm at N-S and 69.00 cm at E-W & 68.50 cm at N-S) and stem diameter (0.60 cm and 1.15 cm) at 30 and 60 DAP respectively. While number of main stems per plant was not affected by the imposed treatments during both the seasons.
Keywords: Growth, nitrogen, phosphorus, potassium and micronutrients
