Abstract: The experiment entitled “Effect of macro and micro nutrients on flowering, fruiting and yield of Acid lime” was conducted at fruit research station Imalia, Department of horticulture, JNKVV, Jabalpur (MP) during the 2017-2018. The experiment was laid out in randomized block design (RBD) with 19 treatments and three replications. Twelve years old uniform trees of acid lime fruit research station Imalia (Citrus aurantifolia Swingle) were selected for the study. The result revealed that the highest Number of fruit/plant (960), Fruit yield (43.3 kg/plant) and physico - chemical composition i.e. Maximum fruit length (39.1mm, 40.0mm, 43.9mm & fruit girth 41.6mm, 43.5mm, 43.6mm at 60, 90 & 120 days, respectively), maximum fruit weight (47.08g) at harvest, juice content (60.46%), minimum 7 seed/ fruit, highest peel thickness (1.65mm), lowest peel/ juice ratio (0.098) & peel/ juice ratio (0.105) and maximum TSS (8.22 0Brix), Ascorbic Acid (34.18 mg/100g) and minimum acidity (6.40%) was recorded with foliar application of T₁₅ (Urea (4%) + ZnSO4 (0.8%) was significantly superior than all over treatment. Maximum net return (747548 Rs. /ha ^-1) and Benefit cost ratio 6.21:1 were found with the application of Urea (4%) + ZnSO₄ (0.8%) and minimum net return (506027 Rs/ha^-1) and Benefit cost ratio was recorded 4.08:1 under control.
