Abstract: Liquid fertilizers derived from seaweeds are found to be superior to chemical fertilizers due to high level of organic matter, micro and macro elements, vitamins and fatty acids and also rich in growth regulators. Loquat seedlings Eriobotrya japonica grow slowly under nursery conditions, usually stay for a long time until a diameter up to appropriate size for budding and thus reach the ready size for the sale, this investigation aimed to improve the vegetative growth of the seedlings by studying the effectiveness of concentration and method of application of seaweed concentrate SWC Kelpak consists of natural plant hormones such as auxins (10.7 mg.l-1) and cytokinins (0.03mg.l-1) which is produced from Ecklonia maxima, which stimulate growth, on loquat transplants grown at the lathhouse of Agriculture Research Centre, Ainkawa, Erbil, Iraq, during April to August 2010, as soil and foliar application in the following concentrations ( 0, 1:200, 1:250, 1:300), and the overlap between concentration and method of application to improve the vegetative growth of the seedlings, each treatment was repeated three times through the growing season the interval date between them were 20 days. For the control treatment, pure water was used, Complete Randomized Design (C.R.D) as a factorial experiment design with three replicates.
