Zinc (Zn) deficiency is prevalent worldwide and is a barrier to achieving yield goals in crops. It is also now recognized as a leading risk factor for disease in humans in developing countries. In general, soil application of 5–17 kg of Zn ha−1 year−1 as zinc sulphate (ZnSO4) or more is recommended. However, in developing rice growing countries of Asia, ZnSO4 of desired quality is not readily available and is also quite expensive, so the farmers generally fail to apply Zn, resulting in rice… CONTINUE READING
