This experiment was conducted in the nursery of Al-Diwaniyah Governorate/Iraq during the year 2021
to know the effect of Mg nano fertilizer and the balanced NPK compound foliar fertilizer (20-20-20) as
well as to find out their interactions in improving the chemical properties of fenugreek plant. The nanofertilizer was prepared in three levels 1, 2 and 3 g/l by dissolving the required amount of nano-Mg
fertilizer in distilled water and completing the volume to one litre to get the above levels, according to
the instructions of the Iranian Green Company, a manufacturer of nano-fertilizers. The foliar fertilizer
prepared by the American company PRO-SOL and available in some agricultural offices in Baghdad was
prepared in three levels, which were 1, 1.5 and 2 g/l of water. Nano-Mg did not give significant significance
in phosphorus and potassium, while significant differences appeared in the rest of the elements
represented by nitrogen, calcium, protein percentage, carbohydrates and fats. As for the balanced foliar
fertilizer and the combination of nano-Mg and fertilizer, they showed significant indications in all of
those mentioned elements.
Key words : Fenugreek plant, Trigonella foenum-graecum L., nano-magnesium, foliar fertilization, NPK
