Abstract

In the course of the study, granules of the composite material “chitosan - titanium dioxide” with different content of titanium dioxide nanoparticles for agricultural use were obtained. The average granule diameter was 35 mm. It is shown that a change in the concentration of titanium dioxide nanoparticles in a composite material within the studied limits does not affect the structure of its surface. Experiments were carried out in situ on the seeds of cucumber (Cucumis sativus). It was noted that during the first three weeks, the composite material has an inhibitory effect on plant growth, and then, after the beginning of the dissolution of the granules, it has a growth-stimulating effect. The best growth rates were observed when two granules of a composite material were added to the soil with a ratio of chitosan to titanium dioxide of 3 to 1. It was concluded that the obtained granules of a composite material can have a positive effect on the processes of plant growth and formation.
