Development of organic farming has led to the production of new organic fertilizers. They can increase seedlings vigour and resistance to pathogens and pests attack as well as a good survival in less favourable conditions after crop establishment. In this paper, a preliminary study was conducted to evaluate the response of Paulownia seedlings to organic fertilizers. Currently, the interest for this species is increasing due to its many qualities: decorative rapid growth, the honey tree and an excellent wood for timber, especially plant biomass production and capacity of air purification in polluted areas. After transplanting, 3 treatments have been applied to seedlings root, at an interval of 7 days. Response assessment was done through biometric measurements on height and stem diameter, number of leaves/plant, root length and leaf area. Treated seedlings were found to be superior to the untreated seedlings. Among the treatments applied, Organic NK-Fertilizer gave a significant advantage over the rest of the treatments in terms of seedlings vigor while bacterial culture led to a good development of the root system.
