A field experiment entitled effect of biofertilizers and micronutrients on yield and quality of garlic (Allium sativum L.) var. G-282' under black cotton soils in Jhalawar condition was conducted during the rabi season in 2012-13 at the Department of Vegetable Science, College of Horticulture & Forestry, Jhalawar. The experiment was carried out by inoculating 2 biofertilizers viz., PSB and Azotobacter and foliar spray of 3 micronutrients viz., 0.4% ZnSO4, 0.2% Boric acid and 0.05% CuSO4. The application of biofertilizers and micronutrients had significant effect on yield and quality of garlic over control. The treatment T5 (PSB + 0.4% ZnSO4) recorded maximum yield attributes like fresh weight of bulb (34.37 g), diameter of bulb (5.49 cm), number of cloves per bulb (30.67 cloves), fresh weight of 50 cloves (86.67 g), dry weight of 50 cloves (42.50 g), bulb yield per plot (5.15 kg plot-1), bulb yield per hectare (229.03 q ha-1) and quality attributes like TSS (43.33 %), ascorbic acid content (15.60 mg /100 g), dry matter content in bulb (49.01 %), nitrogen (3.33 %), crude protein (20.80 %), sulphur (1.48 %) and pungency (72.33 ?mol/g) in bulb. The treatment T6 (PSB + ZnSO4) and T9 (Azotobacter + ZnSO4) were at par with T5 in most of the characters such as neck thickness, diameter of bulb, fresh weight of 50 cloves, bulb yield plot-1, bulb yield ha-1 and ascorbic acid in bulb and the maximum nitrogen content (357.67 kg N ha-1), phosphorus (25.33 kg P ha-1) and potassium (227 kg K ha-1) was recorded with the treatment T11 (Azotobacter + CuSO4 @ 0.05%) and minimum in T5 (PSB + ZnSO4 @ 0.4%) i.e. 338.33 kg N ha-1, 20 kg P ha-1 & 223.33 kg K ha-1)
