The article provides, according to the planting rate and phenological observations, the cultivation of annual saplings of Magnolia grandiflora when growing saplings from seeds. In order to accelerate the cultivation of young seedlings of the magnolia plant, work is underway to apply mineral fertilizers in various ways, and the results are recorded in a field journal. Experiments were carried out on a variation basis and 30 plant samples were obtained for each variation. In addition to the application of experimental fertilizers, additional preparations were used to protect our plants from various external influences: 1 g/1 of succinic acid was prepared from the roots and leaves in 5-7 days to remove leaves from stress. In addition to mineral fertilizers, organic (rotten manure) fertilizers were also used. The growth, development and characteristics of magnolia seeds were studied at the Andijan branch of the Research Institute of Forestry. As well as, growth rates, duration of ontogenetic cycles, moisture and mineral nutrition requirements, disease and pest resistance were also determined.
