The objective of the present work was to evaluate the quality of seedlings of Moringa oleifera Lam. according to seeds position in the fruit and the concentration of nutrients in the fertigation solution. An experiment was carried out following entirely randomized design, with treatments arranged in a factorial scheme 3 x 4, in which the factors were three positions of seeds in the fruit (basal, medium and apical) and four doses of nutrients (0, 50, 100 and 150% of the standard dose), with four replications. The following parameters were evaluated: height (H), collar diameter (CD), leaf number, aerial dry mass (ADM), dry mass of the root system (DMRS), total dry mass, H/CD ratio, ADM/DMRS ratio and Dickson quality index. Data of the effect of seeds position in the fruit were submitted to analysis of variance with test F and comparison of means by Tukey´s test at 5% of probability, while data of nutrients levels was submitted to regression analysis. Seeds position in the fruit did not influence seedlings vigor. Fertigation solution with nutrients concentration varying between 80 and 100% of considered standard solution is recommended for similar conditions of this experiment.
