Response of Pomegranate Trees (Punica granatum L.) Cv. Salimi and Wonderful to Organic Fertilizers and Its Interactions With Bread Yeast Sacchromyce Cervisiae


A study was conducted in the Pomegranate orchard at Ramadi cityAnbar province during the growing season 2013, to understand the effect of organic fertilizers (Cattle and Pigeon manure) and its interactions with the bread yeast (Sacchromyce cervisiae) on some vegetative growth of two pomegranate cultivars Salimi and Wonderful. Homogenous trees have been selected at age of two years with on 4x4 m planting distance. The Cattle and Pigeon manures were added in the middle of January, while 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 showed that the organic fertilizers as added alone or combined with the yeast suspension affected significantly in all of vegetative growth traits. The T9 treatment (4 kg.tree-1 cattle manure + 20 gm.l-1 yeast suspension) was gave the best percentages in leaves dry matter and leaf area reached 56.81% and 7.67cm2, respectively. Followed by T7 treatment (4 kg.tree-1 pigeon manure + 20 gm.l-1 yeast suspension) in the positive effects as it achieved high positive effects for plant high , dry matter percentage in branches and chlorophyll content in leaves reached 41.8 cm , 68.19% and 58.63 spad. The two pomegranate cultivars difference significantly in some of the vegetative growth traits, and Salimi cultivar gave the higher value for length of new branches, On the other hand wonderful cultivar achieved highest value for the traits plant height, leaves dry matter percentage.
