Abstractstudy was carried out in the Pomegranate orchard at Ramadi city center of Anbar province during the growing season 2013, to show the effect of organic fertilizers (Cattle and Pigeon manure) that combined with the dry bread yeast(Saccharomyce cerevisiae) on growth of two pomegranate cultivars Salimi and Wonderful. Homogenous trees have been selected at age of two years.
The two organic manures were added in the middle of January, whereas the yeast suspension was added at the three times (middle of February, at the flowering and four weeks after the second time). A factorial experiment with three replicates was carried out in a split plot design, using one tree for each experimental unit. Results revealed that the organic fertilizers as added alone or combined with the dry yeast affected significantly in all of vegetative growth traits. The T9 treatment was gave the best percentages in leaves dry matter, phosphorus and potassium reached 56.81%, 0.54% and 0.89%, respectively. The high average of new branches length and percentage of Nitrogen in branches were in T8 treatment reached 34.35 cm and 1.76%, respectively. While the T7 treatment was showed high level of Carbohydrates in branches was 8.55%. On the other hand, the low values of the above traits were at the T0 treatment reached 48.62%, 0.34%, 0.72%, 1.48%, 22.79 cm, and 5.18%, respectively.
No significant effects have detected in the rest of traits as a response to cultivars change except the length of new branches, and percentages of dry matter, and carbohydrates. The interaction between studied factors reached a significant level in all of study traits except the percentages of dry matter and phosphorus. The lowest value of interactions between the study factors showed by the control treatments of both cultivars.
