Abstract:
The present investigation entitled “Effect of integrated nutrient management on growth and yield of Radish (Raphanus sativus L.) var. Pusa Chetki Long” was carried out during the Rabi season of the year 2022-23 at the Arunachal University of Studies, Namsai, Arunachal Pradesh. The main objective of this field study was to evaluate the effect of organic manures, inorganic manures and biofertilizers with different doses on the growth and yield of radish and also to study the economics for each treatment. The experiment was laid out in Randomized Block Design (RBD) with seven treatments replicated thrice. The treatments were via T₀ (Control), T₁ (20 t/ ha FYM + 100: 60: 100 NPK + 0.05 Azotobacter), T₂ (16 t/ ha FYM +130: 80: 130 NPK+ 0.04 Azotobacter), T₃ (12 t/ ha FYM + 150: 90: 150 NPK + 0.05 Azotobacter), T₄ (8 t/ ha FYM + 60: 40: 60 NPK + 0.04 Azotobacter), T₅ (4 t/ ha FYM + 30:20:30NPK + 0.05 Azotobacter), and T₆ (1 t/ ha FYM + 15:10:15 NPK + 0.04 Azotobacter). The results revealed that application of T₃ (12 t/ ha FYM + 150: 90:150 NPK + 0.05 Azotobacter) recorded significantly higher plant height, number of leaves and yield attributes like root length, root girth, fresh weight of root and root yield. Also recorded highest B:C ratio under the treatment T₃ (12 t/ ha FYM + 150: 90:150 NPK + 0.05 Azotobacter).
