An economic evaluation of the effectiveness of the application of different rates of fertilizers in short crop rotation on lands contaminated with radionuclides in 2015–2017 was carried out. It was established that the highest level of conditional net profit was obtained from growing corn: from 1,624.80 to 13,978.80 UAH/ha, with a profitability of 8.5–92.8%. The highest level of profitability was obtained for the cultivation of triticale – from 10.0 to 100.4%, conditional net profit was obtained from 1216.38 to 6925.20 UAH/ha. For the cultivation of oats in 2015–2017, it was possible to obtain from 2720.60 to 6937.60 UAH/ha of conditional net profit and profitability from 18.9 to 70.3%. From the cultivation of lupine, the level of conditional net profit was from 790.40 to 4823.80 UAH/ha, and the profitability was 8.4–77.7%. From 656.40 to 10,314.50 UAH/ha of conventional net profit was obtained for the cultivation of fodder beets, with a profitability of 3.2–85.4%. The cost of growing 1 ton of oat grain in 2015 was UAH 3,640.0 for a yield of 2.71 t/ha, in 2016 – UAH 3,851.0 for a yield of 2.46 t/ha, in 2017 – UAH 3,983.0 for yield of 2.41 t/ha. The cost of growing 1 ton of triticale grain in 2015 was UAH 1,497.0 for a yield of 4.47 t/ha, in 2016 – UAH 1,620.0 for a yield of 4.15 t/ha, in 2017 – UAH 1,760.0 for yield of 3.98 t/ha. The cost of growing 1 ton of lupine in 2015 was UAH 3,015.0 for a yield of 1.94 t/ha, in 2016 – UAH 3,254.0 for a yield of 1.81 t/ha, in 2017 – UAH 3,490.0 for a yield 1.78 t/ha. The cost of growing 1 ton of fodder beet in 2015 was UAH 353.0 for a yield of 29.71 t/ha, in 2016 – UAH 380.0 for a yield of 30.65 t/ha, in 2017 – UAH 410.0 for yield of 29.47 t/ha. The cost of growing 1 ton of corn grain in 2015 was UAH 2,030.0 for a yield of 4.89 t/ha, in 2016 – UAH 2,120.0 for a yield of 5.43 t/ha, in 2017 – UAH 2,282.0 for yield of 6.60 t/ha. Although the highest economic efficiency was obtained in the variant without the use of fertilizers, the grown products were the most contaminated with radionuclides. The lowest indicators of economic efficiency were obtained in the 3rd version of fertilizer, where the grown products had the lowest concentration of radionuclides. Also, in the studied agricultural products in the 2 and 3 versions of fertilizer, a higher content of crude protein, crude fat and crude fiber was observed compared to the control.
