AbstractA study was conducted in one of the olive orchard at Al-Forat governorate in Heet city of Al-anbar province during the season 2014 to investigate the effect ofapplying the industrial chicken manure the Orgevit (P) and spraying the Reef PlantCare (V) on some vegetative growth traits of olive seedlings Ashrasi cultivar.
Thirty sex identical seedlings as possible were chosen at age of two years with interspace of 6x6 m. The Orgevit was applied in the middle of March, while the Reef PlantCare was at monthly intervals, starting from the 1st of April to October the 1st . A factorial experiment was carried out in R.C.B.D. design (3×4) included 12 treatments repeated three times, using one tree for each experimental unit, The first factor (Orgevit) was used in three levels ( 0 , 0.5 and 1 kg.seedling-1 ), whereas the second factor was spraying with the Reef PlantCare in four levels (0 , 1 , 1.5 and 2 ml.l-1 ) .
The results showed the Orgevit manure was significantly affected in growth of olive seedlings Ashrasi cultivar, especially the highest level used (P2) which showed the best values for all the studied traits (average of high increment, average of branches number increment, average of a new branches length, average of leaves number increment and branches dry matter percentage) which reached (11.7 cm, 11.83 branch.seedling-1 , 13.5 cm, 56.4 leaf.seedling-1 and 67.29%) respectively, only the average increment of stem diameter didn't show any significant difference. Treatment of spraying Reef PlantCare at the highest level (V3) was the best by giving the highest significant effect for the two traits (average of branches number increment and branches dry matter percentage) that reached 11.00 branch.seeedling-1 and 65.03%, respectively. Treatment V2 was came after and showed significant effect on traits (average of high increment, average of a new branches length and average of leaves number increment) that reached 11.8 cm, 13.4 cm and 54.7 leaf.seeedling-1, respectively. The interaction combinations gave a significant level for the all studied traits, the highest effects for most traits was for the interaction treatment P2V2
