Effect of organic and inorganic fertilizers on the concentration of Fe, Mn and Cu in spring wheat (Tritcum astvium L.)‎ genotypes

الملخص EN

Fe, Mn, and Cu are essential micronutrients for both plants and humans.

Deficiency in these micronutrients in the human body can result in a range of severe adverse consequences.

Therefore, the concentrations of these elements in seven different wheat (Tritcum astvium L.) genotypes were studied under organic and inorganic (conventional) fertilization.

Under organic fertilization, the concentration of micro elements was higher than that under conventional fertilization.

The increase in grain content of micro elements was due to the high organic fertilizer content of micronutrients and the improved soil pH through organic fertilizer addition.

Fe content in grains ranged from 39.0–92.3 mg kg−1 in Egyptian genotype ‘Sids12’ and local Saudi Arabian genotype ‘Sama,’ respectively.

Cu content in different wheat genotypes ranged from 3.94–5.0 mg kg−1 in ‘Yocora Rojo’ and ‘IC17,’ respectively.

Mn content in different wheat genotypes ranged from 29.8–46.4 mg kg−1 in Australian wheat genotype ‘P5’ and ‘Sama,’ respectively.

There was only a small increase in Cu concentration in grains under organic fertilization compared with non-organic fertilization in some genotypes.

Mn concentration in grains was higher under organic fertilization compared with non-organic fertilization in most of the genotypes.

The local genotype exhibited the highest Mn concentration under both fertilizers.

Therefore, the genotypes ‘Sama’ and ‘IC17’ can be considered to be good sources of nutrition
