استجابة صنفين من العدس و صنف من القمح لإضافة السماد الفوسفاتي و التلقيح بفطر المايكورايزا

Abstract EN

Two pot experiments were carried out in a greenhouse to determine the efficiency of two lentil varieties and one wheat variety under different phosphate and mycorrhiza rates.

The first experiment had two types of Syrian soils with and without application of phosphate fertilizer (0, 120 kg P2O5/ha).

Split-Split-Plot-design was used to evaluate the varieties with three replicates.

Two soils types (Tatmrash and Ketyan) were placed as main plots, sub-plots were assigned for phosphate application and sub-sub plot were for varieties (Two varieties lentil: ILL1005 and ILL590 and one drum wheat variety: Cham3) .

The results showed that legumes were more efficient in phosphate availability in the soil compared with wheat.

Application of phosphate fertilizer led to an increase in grain yield (1 0% for lentil and 7% for wheat).

The second experiment contain ILL590 with application of phosphate fertilizer (0, 50, 100, 150 and 200 Kg P2O5/ha), two types of mycorrhiza (250 spore/pot for Glomus mosseae,and Glomus caledonioum) and three levels of mycorrhiza (without phosphate fertilizer) (0, 100, 250 spore/pot) with three replicates.

Fertilized treatments showed significant superiority over the non-fertilized ones.

There was a significant increase in grain yield with mycorrhiza application (without phosphate).

Available phosphorus concentration increased by 1111% with inoculation with G.

mosseae.

Phosphorus uptake efficiency decreased by 44%, 61% 73% for the fertilizer levels 100, 150 and 200 kg P2O5/ha respectively compared with the treatments with 50 kg P2O5/ha.
