Review Paper on Effect of Micronutrients for Crop Production

Micronutrients are essentially as important macronutrients to have better growth, yield and quality in plants. There requirement by plants is trace amounts. Boron, iron, copper, zinc, manganese, magnesium molybdenum constitute main micronutrients required different crops variable quantities. The of partly met from the soil or through chemical fertilizer other sources. Various physical metabolic functions governed these mineral nutrients. Boron particularly essential pollen germination, copper plays major role photosynthesis increases sugar content fruits, chlorophyll synthesis phosphorus availability enhanced iron acts an oxygen carrier promotes formation, while, zinc aids plant growth hormones enzyme system. Yield agricultural products increased with application, therefore human animal health protected feed enrichment materials. Each element only when can perform its nutrition properly that necessary elements available balanced ratios for plant. manganese on oxidation reduction processes, electron transport photosynthesis. Manganese deficiency has very serious effects non-structural carbohydrates, roots carbohydrates especially. Crops quantity decreased due deficiency, this low fertility during grain filling. In xylem routes transmitted divalent form organic acids bond. phloem sap makes up complex molecular weight, concentration. Zinc be seen eroded, calcareous weathering acidic soils. often accompanied Iron fourth abundant earth, but amount was not microorganisms needs, solubility minerals containing many places world, especially arid region alkaline
