Effect of nano urea on growth, yield and quality of Tomato (Solanum lycopersicum L.) cv. Azad T-6

The field experiment was conducted during the rabi season 2024-25 at Department of Vegetable Science Kalyanpur of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, (U.P.). Nine different treatments viz.,100% RDN + foliar spray with water (control) (T₁), 100% RDN + one spray of nano urea @ 4 ml/litre at 30 DAT (T₂), 100% RDN + two sprays of nano urea @ 4 ml/litre at 30 and 50 DAT (T₃), 75% RDN + foliar spray with water (T₄), 75% RDN + one spray of nano urea @ 4 ml/litre at 30 DAT (T₅), 75% RDN + two sprays of nano urea @ 4 ml/litre at 30 and 50 DAT (T₆), 50% RDN + foliar spray with water (T₇), 50% RDN + one spray of nano urea @ 4 ml/litre at 30 DAT (T₈) and 50% RDN + two sprays of nano urea @ 4 ml/litre at 30 and 50 DAT (T₉) were tested against no nitrogen (T₁₀) in a RBD replicated thrice. The tomato variety Azad T-6 was used in experiment. The results of the experiment revealed that application of 100% RDN + two foliar sprays of nano urea @ 4 ml /lit at 30 and 50 DAT (T₃) recorded significantly highest plant height (35.96 and 43.23 cm at 60 and 90 DAT, respectively), number of branches (9.01),fruit equatorial diameter (5.59 cm), fruit polar diameter (5.14 cm), average fruits weight (59.89 gm 4^th picking), number of fruits per plant (35.51), yield per plant (1.90 kg), yield per plot (56.84 kg), yield (438.66 q/ha), TSS (5.34 °Brix) and ascorbic acid (16.82 mg/100g). Based on the results, it can be concluded that application of 100% RDN + two foliar sprays of nano urea @ 4 ml /lit at 30 and 50 DAT (T₃) markedly enhanced the yield and fruit quality. Hence, this may be recommended for commercial cultivation of Tomato cv. Azad T-6 under Kanpur conditions to maximize productivity.
