Abstract. In this article, the results of the research on the evaluation of the parameters of propagation of paper tree seedlings from cuttings are presented, experimental works on growing paper tree seedlings by vegetative method in 4 types of options were carried out. Sand (control), biosulphate, hydroxide and root energy stimulants were used as growing media. The temperature of the experiment area was monitored. During the rooting of cuttings, it was observed that the temperature of the region was 18-24°, air humidity was 40-50%, and sand humidity was 30-40 degrees depending on the temperature (based on the indicators of the soil moisture measuring device). It was observed that the parameters of vegetative rooting of paper tree seedlings are in 3-5 days. Taking into account plant transpiration and evaporation of water into the air, 15-20 liters of water were poured in 10-12 days, and the duration and watering norms of vegetative rooting, as well as root length and leaf indicators of rooted seedlings information on.
