Role of Micronutrients in Crop Production

The roles of some of the micronutrients within the plant system are as follows:

Iron (Fe): Iron plays a vital role in the synthesis of chlorophyll, carbohydrate production, cell respiration, reduction of Nitrate sulphate and N assimilation.

Manganese (Mn): Manganese activates a number of enzymes. It is essential for splitting the water molecule during photosynthesis. It is also important in N metabolism and CO₂ assimilation.

Zinc (Zn): Zinc is essential for auxin and protein synthesis, seed production and proper maturity.

Copper (Cu): Copper is involved in chlorophyll formation and is a part of several important enzyme systems involved in proper growth and development of plant. It is also essential for the production of vitamin A and also encourages the reproduction process.

Boron (B): Boron is essential for membrane integrity, cell wall development, cell division and cell elongation. It is also required for the proper growth of pollen tube and for the process of reproduction.

Molybdenum (Mo): It is directly involved in protein synthesis and nitrogen fixation by legumes.
