Effect of Nano Urea on Jamun (Syzygium cuminii L.) Grafts cv Konkan Bahadoli

The experiment was conducted during the period 2023-2024 at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri. The experiment was laid out in Randomized Block Design (RBD) with twelve treatments viz., T1: Control (Soil + FYM No nano urea treatment), T2: Top dressing (Soil +FYM mixture 2:1 + 2g urea /plant, T3 : Foliar spray of nano urea 500 ppm, T4 : Foliar spray of nano urea 1000 ppm, T5 : Foliar spray of nano urea 1500 ppm, T6: Foliar spray of nano urea 2000 ppm, T7 : Foliar spray of nano urea 2500 ppm, T8 : Drenching of nano urea 1500 ppm, T9 : Drenching of nano urea 2000 ppm, T10 : Drenching of nano urea 2500 ppm, T11 : Drenching of nano urea 3000 ppm,T12 : Drenching on nano urea 3500 ppm. All the treatments replicated thrice. From the findings, it is concluded that grafts drenched with 3000 ppm of nano urea showed outstanding results as that of control. At 270 days, after drenching of 3000 ppm of nano urea, grafts recorded maximum plant height (21.42%), highest stem girth (21.23%), number of branches (15.31 %), number of leaves (18.21 %), leaf area (23.05 %), absolute growth rate (34.73 %), dry weight of shoot (21.50%), dry weight of root (26.89 %), root length (30.72 %). Thus, it can be concluded that drenching of nano urea (3000 ppm) gives significant result to growth of jamun grafts.
