| Summary: In an experiment with one-year old plants Aleppo Pine and Stone Pine plants the effect of two types of slow re/ease "Osmocote" fertilizers, classical phosphorous fertilizer superphosphate and a complex fertilizer 7:14:21 were examined. The effect of fertilisation on growth and plant nutrition, and the quality of the seedlings produced, was investigated. Peat from Latvia was used as a sowing substrate. In all treatments a positive effect of fertilisation on plant growth was confirmed. A relatively stronger reaction to the applied mineral fertilizers was observed in Aleppo Pine compared to Stone Pine. In a coinbonaliou in which 3 kg in´ of "Osmocote Mini " was introduced into the substrate, plants of both species had the greatest heights, and Aleppo Pine plants also had the greatest diameters. A dose of 6 kg/ms of "Osmocote Mini "fertilizer negatively influenced plant growth compared to a dose 3 kg/in´ of the same fertilizer. The plants had bluish-green needles and werepoortly lignificd. BY dividing the 3 kg/in1 dose of "Osmocote Mini "fertilizer into two parts and introducing 1.5 kg/nf into the substrate, and the remaining pari applied by top dressing, did not have a positive effect on plant growth. Surface application of this fertilizer negatively affected root development. The introduction of superphosphate and complex fertilizer positively affected the growth of Aleppo Pine. Better result was achieved by superphosphate. Very good lignification of plants was determined by treatment with superphosphate in both investigated species and a positive effect of phosphorous on development or root system. Additional treatment wich "Osmocote Mini"ferlizer had a stronger effect on plant growth than "Osmocote Sierrablen". The applied fertilization had an effect on increased concentrations of relevant nutritional elements in the substrate and plants. Better developed plants of Stone Pine accumulated significantly more nutriens than Aleppo Pine plants. The use of mineral fertilizer had a strong effect on absorption of corresponding nutriens in both investigated species. With a dose of 1.5 kg/m3 "Osmocote Mini" high quality Stone Pine seedlings were cultivated, while in the case of Allepo Pine the dose should be increased.
