Pear is one of the most consumed fruit all over the world. In Romania also is among most cultivated fruit. It is due, not only to preference of fruit consumers, but also because it is a most valuable raw material for genuine natural beverage product â€tuicaâ€. The trial was developed in a private nursery from Vâlcele, county of Cluj. Pear seedlings (Pyrus communis L.) were used.   Three fertilization variants were used: NPK (15:15:15) - control, fly ash, and magnetic fertilizer. The seedlings’ development was assessed in mid-October, by measuring the shoots’ growing, and trunk diameter at 5 cm height above ground. Data were statistically processed with STATISTICA v. 7.0 for Windows. The administration of magnetic fertilizer led to best results, compared to N15P15K15 mineral fertilizer and fly ash, concerning the evolution of shoots’ height and trunk diameters within nursery conditions. Even though, the use of magnetic fertilizer led to weakest correlation between shoots’ height and trunk diameter. These results led us to conclude that further research is needed in order to state the influence of unconventional fertilization upon pear seedlings development.
