Do all crops have the same sensitivity to zinc deficiency?
Although zinc deficiency is known to affect a wide range of crops in many parts of the world, genotypic differences between species render some crops more susceptible to deficiency than others. Apart from inter-specific differences, there are also important intra-specific differences which can in some cases be greater than differences between species. In the case of wheat, Durum wheat (Triticum durum) is more susceptible to zinc deficiency than bread wheat (Triticum aestivum). However, there are considerable varietal differences in both types of wheat.
