Varietal differences in responses to manganese and zinc locations
Aims

To examine the ability of genotypes of wheat and barley to produce high yields on micronutrient deficient soils.

Key messages
  • The relative sensitivity to manganese deficiency is broadly : bread wheat (least), barley, durum wheat (most).
  • The relative sensitivity to zinc deficiency is broadly: barley (least) bread wheat, durum wheat (most).
  • With a very inefficient variety adding a micronutrient fertiliser may not be sufficient to overcome the deficiency.
  • Special attention needs to be given to the micronutrient requirements of durum wheat especially where high rates of N and P fertilisers are used.
