Effect of soil applying Orgevit and Spraying Reef plant care in elements content of Olive seedlings cv. Ashrasi grown in desert lands

Abstract

A study was conducted to investigate the effect of applying the industrial chicken manure the Orgevit (P) and spraying with the Reef PlantCare (V) in chemical content of olive transplants cv. Ashrasi that planting in one of the orchard that located in desert lands at Al-Forat district that distance 40 km west of Ramadi city during the season 2014. Thirty sex identical seedlings as possible were chosen at age of two years with inter space of 6x6 m. The Orgevit was applied to the soil in the middle of March at three levels 0, 0.5 and 1 kg seedling-1, while the Reef Plant Care was at monthly intervals, starting from the 1st of April to October the 1st at four levels 0, 1, 1.5 and 2 ml L-1 ). 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. Applying the Orgevit manure was significantly affected all the traits especially the highest level (P2) which showed the best values for transplants branches content of elements; Magnesium, Manganese, Iron, Zinc and Copper, which reached 0.32 %, 41.81, 179.31, 82.42 and 35.0 mg kg-1, respectively, While the branches content of Mg and Fe significantly increased when spraying by Reef PlantCare which gave the highest values at the level (V3) reached 0.33% and 174.82 mg kg-1, respectively. While no significant effects have detected in the other elements as a response to spraying by Reef Plant Care. The interaction between the two factors reached a significant level for the all studied traits and the highest effect of interactions was depended on the treatment type, whereas the lowest values to the most of traits were shown at the control treatment (P0V0).
