يعتبر القمح واحد من أهم المحاصيل الغذائية الإستراتيجية على مستوى العالم؛ لضمان الأمن الغذائي، إزداد الطلب على القمح زيادة هائلة مع زيادة عدد السكان.

يعد القمح مصدر مهم للكربوهيدرات على المستوى العالمي، بالإضافة إلى أنه المصدر الرئيسي للبروتين النباتي في الأغذية البشرية، حيث يحتوي على نسبة من البروتين تبلغ حوالي 13٪، وهي نسبة مرتفعة نسبيًا مقارنة بالحبوب الرئيسية الأخرى، ولكنها منخفضة نسبيًا في جودة البروتين لتوفير الأحماض الأمينية الأساسية.

يعتبر محصول موسمي بارد، يزرع على نطاق واسع في ظل ظروف بيئية زراعية متنوعة.

دور العناصر

Wheat crop is one of the most consumed cereal crops around the world. Potassium plays a major and important role in improving productivity and quality through:

The use of potassium on wheat increases vegetative growth of plants.

  • Increases wheat grains yield with high seed weight and size.
  • Makes plant more erect.
  • increases the plant's resistance to unfavorable environmental conditions.

One of the most important functions of phosphorus in wheat crop

  • Helps seeds germination and the development and growth of seedlings.
  • Increases the efficiency of roots growth and increase water and nutrients use efficiency.
  • Leads to increase tillering rate.
  • Increased seed and straw yield.
  • Helps the plant to adapt to environmental stress.

Calcium has an important role in the wheat crop as it:

  • Increases the plant's ability to resist bacterial and fungal diseases.
  • Increases erectness of leaves and stem.
  • Good root distribution
  • Increase plant resistance to environmental stresses.

أعراض نقص


The symptoms of deficiency initially appear on the leaves in the form of yellowing in the tops of the leaves and then the leaves are damaged and dry and fall as the symptoms of deficiency appear in: -

  • Weak vegetative growth.
  • Makes plant less erect.
  • With low yield of grains
  • On the spikes appears as a general weakness in the spike with fewer grain in the spike.


Phosphorus deficiency Symptoms on wheat crop appearance as red or purple color on the lower leaves and stems in addition to: -

  • Low seed germination.
  • Decrease tillering rate.
  • General decrease plant growth and low yield.
  • Dwarfing the plant and deforming the leaves.


Calcium deficiency symptoms on wheat causes drying of young leaves after that, twist and the lack of calcium leads to: -

  • Plant dwarfing and poor tillering.
  • Failure shoots tips to emerge.
  • Low yield and grains weight.
