The article shows a possibility of using neutralized phosphogypsum as multicomponent fertilizer for rice crops. In the system of rice fertilization replace of 150kg/ha of ammophos during main application with 40 kg/ha of carbamide and 4 tons/ha of phosphogypsum applied in spring provides the same content of available forms of nitrogen, phosphorus and potassium in soil and plants as with application of N120P80K60. Application of phosphogypsum in spring before sowing is less effective than application in autumn before plowing. When applicating phosphogypsum in spring 2013 with a rate of 4 t / ha the obtained yield was 0.57 t / ha or 8.98% higher than in the control, and in 2014 it was not different from that obtained with the application of solid mineral fertilizers with a rate of N120P80K60. With autumn application of phosphogypsum increase in yield in 2014 was 0.98 t / ha or 12.6%. Yield growth is the result of increasing the survival of plants, grain content in panicle and grain weight per plant. Use of neutralized phosphogypsum is economically feasible. Relative benefits of using phosphogypsum instead of phosphorus fertilizer (ammonium phosphate) on rice crops in the Federal State Unitary Enterprise SRSF "Krasnoarmeyskiy" named after A.I.Maystrenko, Krasnoarmeyskiy district of Krasnodar region at the optimal rate amounted to 13139.7 rubles per 1 ha
