Effect of zinc on growth and yield of wheat: A review

Abstract

Zinc is plant micronutrient which is involved in many physiological functions its inadequate supply will reduce crop yields. Zinc deficiency is the most wide spread micronutrient deficiency problem, almost all crops and calcareous, sandy soils, peat soils and soils with high phosphorus and silicon are expected to be deficient. Zinc deficiencies can affect plant by stunting its growth, decreasing number of tillers, chlorosis and smaller leaves, increasing crop maturity period, spikelet sterility and inferior quality of harvested products. Beside its role in crop production Zinc plays a part in the basic roles of cellular functions in all living organisms. Wheat is the main source of food materials for human. The soil and wheat analysed by atomic absorption spectroscopy (AAS) technique.
