Abstract
The article presents the results of studies aimed at identifying the agronomic efficiency and application of phosphogypsum on soybean crops under irrigation conditions. It is shown that the combined use of irrigation with an i rate of 2760 m3/ha, mineral fertilizers and phosphogypsum in various doses provides a significant increase in yield and in soybean quality grain. The most optimal dose of phosphogypsum application (6 t/ha) was revealed. This dose provides soybean yield at the level of 2.53 t/ha.
