Considering the close relationship between soil, water and the plant, the current research aims to establish the influence of irrigation, fertilization, and cultivar on some morphological characters of the apple trees in the nursery. The nursery research sector in our country has demonstrated the necessity of specialization and modernization of this field, due to the growing demand for high-quality certified planting materials. The main aim is to increase continuously the quality and quantity of valuable planting material and guaranteed in terms of authenticity, health, and suitability for the new orchard systems with large plots per hectare and high potential. The research was carried out in the climate conditions of the northwestern Romania and the studied apple cultivars were Florina and Idared, organized on five repetitions, with irrigation as the primary factor, cultivar as the secondary factor and fertilization as the tertiary factor. Following the research, it is found that both the irrigation and the application of different doses of NPK have allowed a significant increase in the survival rate of grafting trees of the two apple cultivars.
