A greater share of influence on the formation of productivity of crops of sweet corn - 53-68 % during 2011-2013 had the soil tillage system in a crop rotation. The higher productivity of sweet corn was formed by a predecessor soybean, and after corn for grain, and after sunflower it was lower by 15.1 and 23.1 %. The traditional soil tillage system provided the accretion of productivity by 13.3 % compared to the minimized system, and compared to the direct sowing by 65.5 %. The shortage of yield of a sweet corn grain in early crops was 16.9 % compared to optimal (ts = 12-14 ° C), and in late crops - 6.1%. The grain yield of a pop-corn, flint corn and flint-and-dent corn was higher when grown after a soybean compared to the predecessor of a corn for grain by 17,3-22,2 %, and to the predecessor of a sunflower - by 21,1-32,0 %. The shortage of yield of grain of a pop-corn in a minimized soil tillage was 20.3 %, without a cultivation - 47.3 %, a flint corn had 24.0 and 46.6 % respectively, and a flint-and-dent corn had 27.6 and 53.2 %. A larger conditionally net profit in growing of a sweet corn - 10704 UAH/ha and by a cost price 448 UAH/t and the profitability 234.7 % was for sowing when the ts = 12-14 оC on a background of a traditional system of a soil tillage after a soybean, and after a corn for grain and a sunflower under similar agromeasures the profit was 9025 and 8583 UAH/ha respectively and the profitability was 198.2 188.6 %. By sowing of a pop-corn with ts = 8.10 оC on a background of a traditional system of a soil tillage after a soybean it was got the largest profit - 10910 UAH/ ha and the profitability 202.1 % at the cost price of grain 1324 UAH/t. The larger profit by a predecessor corn - 9071 UAH/ha was when the sowing was done with a ts = 12-14 оC and in a sunflower - 7807 UAH/ha for sowing when the ts = 8.10 оC also against the background of the traditional system of soil tillage. The higher profit and the profitability of grain production of a flint and flint-and-dent corn were when the sowing was done with the ts = 12-14 оC on a background of a traditional system of a soil tillage: after a soybean - 2540 and 2539 UAH/ha and 45.5 and 42.2 %; after a corn - 2073 and 1553 UAH/ha and 37.9 and 26.0 %, and after a sunflower - 1466 and 1070 UAH/ha and 27.6 and 18.8 %, respectively.
