The present investigation aimed to find out the “Effect of Nano-Fertilizer on Growth and Yield of Green Gram (Vigna radiata L.) was carried out at Agronomy Research Farm of Faculty of Agriculture and Veterinary Science, Mewar University, Gangrar, Chittorgarh, Rajasthan. Geographically Chittorgarh. The experiment was laid out in Randomized Block Design. Replicated thrice with 10 treatment combinations, comprising like T₁ Control, T₂ Foliar spray Nano Zinc @ 1 per cent, T₃ 2 Foliar spray Nano Zinc @ 2 per cent, T₄ Foliar spray Nano DAP @ 1 per cent. T₅ Foliar spray Nano DAP @ 2 per cent, T₆ Foliar spray Nano Urea @ 1 per cent, T₇ Foliar spray Nano Urea @ 2 per cent, T₈ Foliar spray Nano Zinc+ DAP @ 1.5 per cent, T₉ Foliar spray Nano Zinc+ Urea @ 1.5 per cent and T₁₀ Foliar spray Nano Zinc+ DAP+ Urea @ 0.75 per cent. The results reveled that during experiment use of different nano-fertilizer on growth, yield and economics of green gram its effect among all treatments T₁₀ (Foliar spray Nano Zinc+ DAP+ Urea @ 0.75 per cent) was found to significantly increase growth, yield and economics of parameters, yield as well as economic of green gram. It was found that maximum value of growth parameters viz., the plant height was found to be the maximum plant height (35.12, 47.66 and 54.03 cm) at 30 DAS, 45 DAS and at harvest chlorophyll content (1.21) at 40 DAS, dry matter accumulation (4.86 and 7.65) at 25 DAS, 50 DAS, number of branches (6.36, 11.02 and 13.85) at 30 and, 45 DAS and at harvest. Yield attributes and yield viz., grain per pod was recorded significant maximum (6.50), pod length (6.36 cm), grain yield per plot (0.810 kg), higher seed yield (13.50 q/ha), higher biological yield in T₁₀ (38.96 q/ha), maximum straw yield was (25.46 q/ha), maximum harvest index was (34.65 q/ha) economics viz., Maximum fetched value in term of net return (75250.00 /ha) and B: C ratio (2.89) were recorded with foliar spray Nano Zinc+ DAP+ Urea @ 0.75 per cent.
