A study was conducted in one of the olive orchard at Heet city of Al-anbar province during the season 2014 to investigate the feeding by industrial chicken manure (Orgevit) and spraying with the Reef PlantCare on some growth traits and chemical content of olive seedlings Ashrasi cultivar. Thirty sex identical seedlings as possible were chosen at age of two years. The Orgevit was applied in the middle of March, while the spraying with 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 included 12 treatments repeated three times, using one tree for each experimental unit, The first factor (Orgevit manure) was used in three levels (0 , 0.5 and 1 kg.seedling-1) presented with symbols (P0, P1 and P2), whereas the second factor was spraying with the Reef PlantCare in four levels (0 , 1 , 1.5 and 2 ml.l-1 ), mentioned as (V0, V1, V2 and V3).
Applying the Orgevit manure showed significantly affected in all of the studied traits of vegetative growth and chemical component of olive seedlings, especially the highest level used (P2) which showed the best values for traits (leaf area, chlorophyll content in leaves and carbohydrates, nitrogen, phosphorus, potassium percentages in branches) which reached (6.96cm2 , 83.32 spad unit, 7.95%, 1.64%, 0.40% and 0.89%) respectively. spraying with Reef PlantCare was affected significantly especially with the treatment (V3) that gave the best significant effect for the traits (chlorophyll content in leaves, carbohydrates and potassium percentages in branches) which gave (79.51 spad unit, 7.67% and 0.86%, respectively). The interaction between two study factors reached a significant level in all of traits and the highest effect of interactions was depended on the treatment type, whereas the lowest values showed at the control treatment.
