The experiment consisted of 3 Nano-fertilizers viz.Nano urea, Nano DAP and Nano zinc with 4 doses each i.e. 0.05%, 0.1%, 0.15%, and 0.20%, respectively with a total of 13 treatments. The experiment was laid out in a randomized block design (RBD) with three replications each. Results revealed that foliar spray of nano fertilizers had significant effect on all growth, yield and quality of garlic. The treatment T8 (nano DAP @ 0.20%) to the garlic crop has resulted in maximum number of leaves per plant (7.21 and 9.21) length of leaves (49.66 cm and 61.03 cm), plant height (58.05 cm and 68.86 cm) at 60 and 90 DAS, respectively,fresh weight of bulb (29.34 g), length of bulb (4.33 cm), diameter of bulb (4.29 cm), number of cloves per bulb (25.74 ), length of clove (3.94 cm), diameter of clove (1.02 cm), bulb yield per plot (14.08 kg) and per hectare (187.7 q/ha), TSS (42.87 0Brix), dry matter content (42.76%), crude protein content (7.87%), chlorophyll content in leaves (1.83 mg/g) and pungency (10.92 μ mol/g), ascorbic acid (19.93mg/100g) as compared to T0 (control). However, treatments T4 and T12 were statistically found at par with treatment T8. While, the maximum nitrogen content (1.98%) was found in treatment T4 (nano urea@ 0.20%), phosphorus content (0.45%) in T8 (nano DAP @ 0.20%) and zinc content (6.29 mg/100g) in T12 (nano zinc@ 0.2%) in leaf of garlic, as compared to treatment T0 (control).Maximum net returns and B: C ratio, (Rs. 446750.00 and 3.84, respectively) registered in treatment T8 (Nano DAP @0.20%) and minimum net return and B: C ratio (294730.00 ha-1 and 2.60) respectively was recorded in treatment T0 (control).EnglishThesis
