Abstract
The research was carried out during the year 2023 at the Center of Scientific Agricultural Research in Homs, General Commission for Scientific Agricultural Research, on the peanut variety Sahel, to study the effect of mycorrhizal inoculation and phosphate fertilization on some soil fertility characteristics under conditions of deficient irrigation during the flowering and pod formation stages. The experiment was designed according to the Split-split plots design, where stress treatments were placed in the main plots, phosphate fertilization treatments were placed in split plots, and mycorrhizal inoculation treatments were placed in split-split plots with three replicates. The results showed that inoculation with mycorrhiza had a significant effect on increasing the concentration of NPK nutrients available in the soil, and it also had a role in lowering the soil pH, without significant differences between the two stress treatments during the flowering and. pod formation stages. The increased levels of phosphate fertilizer and drought stress also increased the concentration of available phosphorus and potassium, and reduced the content of mineral nitrogen in the soil, without significant differences between the two stress treatments during the flowering and. pod formation stages. Increasing the phosphate fertilization rate had no significant effect on the degree of soil pH, nor did any of the studied factors have any effect on the degree of electrical conductivity of the soil.
Keywords: Mycorrhiza, Phosphate fertilizer, Water stress, Peanut.
