The project was carried out in the trees of Domat olive variety in full production period which was planted in Kemalpaşa Research and Production Station of Olive Research Institute. The trees which were used in the research were irrigated by drip irrigation method. In the research, the effects of the different doses (2 kg/tree and 3 kg/tree) of mineral fertilizer (MF), mineral fertilizer + farmyard manure (MF + FYM) and organomineral fertilizer (OMF) according to control plot (nonfertilizer) on yield, quality and the nutrition of olive trees were examined.

The research was carried on for four years and years were effective on the yield of the parcels that received fertilizer according to control plot in the result of the obtained data. In the fertilizer application, the highest yield was obtained by organomineral fertilizer application. The application of mineral fertilizer + farmyard manure increased the yield only compared to that of mineral fertilizer treatment. In the research, the relationships with the fertilization were determined by analyses of plant nutrients in soil, leaf and fruit samples.
