AbstractThis study was carried out in forest department nursery college of agriculture and forestry, Mosul university, at spring season 2012. The aim of this research to study the effect of organic fertilizer Pow humus and two seaweed extracts Hypra tonic and Alga 300 on growth and development Pinus brutia Ten. and Pinus pinea L. seedlings. Pinus brutia was superior in most vegetative and root parameter length and diameter of stem, number of branchs and root length as compared with Pinus pinea except in shoot to root ratio only. Application of Pow humus matter gave a significant increases higher in stem length, number of branchs and root length . Adding Hypra tonic matter resulted in a significant increase higher in stem diameter, while foliar spraying of Alga 300 matter gave a significant increase higher in shoots to roots ratio. Low concentration was superior in most vegetative and root parameter as compared with high concentration. The tri-interaction (Pinus brutia, Pow humus and low concentration) gave a significant increase higher in stem length, number of branchs and root length, while (Pinus brutia, Alga 300 ana high concentration) recorded a significant increase higher in stem diameter, the interaction (Pinus pinea, Alga 300 and low concentration) gave a significant increase higher in shoots to roots ratio.
