Foliar micro nutrition is the application of micronutrients to plants by spraying directly on to their leaves. Though it is not economical to spray macro as well as micro nutrients through foliar spray, researchers prefer soil application of macronutrient and foliar application of micronutrients. Several researches have demonstrated that the method which is used to deliver the required micronutrient in appropriate concentration to improve nutrient status along with increased yield and quality potential are adapted by combining applications of FeSO4 @0.2%, Calcium [email protected]%, Boron @0.1% and ZnSO4 @0.2% has revealed a 51% increase as compared to control in potato. Application of ZnSO4 0.4% and ZnSO4 0.6% provides significant impact on growth and yield characteristic of Chilli; Zinc Sulfate (0.5%) and Borax (0.5%) also shows better result on the number of fruits per plant, fruit length, fruit diameter and yield per plant in Eggplant. Applying ZnSO4 (0.5%) shows better results on plant height, weight of head, yield of head in cabbage cultivations. Combined application of Boron 100 ppm+Molybdenum 50 ppm along with 60 kg/fed of Nitrogen shows 38.02% increase on curd yield of cauliflower over control. A study reveals that application of (0.5%) Zn+(0.1%) B along with 75 kg/ha potassium in combination showed 31.73% increases yield of watermelon. Boron application @0.25% and Zinc 0.5% showed 31.17% increase in total yield of Onion. With combined application of MgSO4 (0.5%), MnSO4 (0.5%), FeSO4 (0.5%) and ZnSO4 (0.5%) has increased yield of okra 31.8% over control. In general this critical review lays an emphasis from the review point of that micronutrients have been found to show satisfactory results than control conditions and has an immense potential in vegetable production to increase yield attributes.
