The role of magnesium in increasing of phosphorus fertilizer efficiency and wheat yield

الملخص EN

The study was conducted during the growing season 2003 to study the influence of four levels of P (0, 60, 100 and 140 kg ha-1) and four levels of Mg (0, 40, 80 and 120 kg ha-1) at two locations (Bakrajow and Kalar) on growth and yield of wheat and phosphorus fertilizer efficiency.

The results indicated to the response of wheat to phosphorous fertilizer at Bakrajow location only.

While the application of 40 kg Mg ha-1 caused significant increase in wheat yield at Bakrajow location only.

The highest phosphorus fertilizer efficiency was 34.44 % and 55.24 % at Bakrajow and Kalar respectively while the Mg fertilizer efficiency was 7.6 % and 22.8 % at Kalar and Bakrajow respectively.
