The substantiation of optimization of cultivated areas ratio for grain crops in the Perm region in favor of higher-yielding crops, such as barley, oats, and winter cereal crops is given. The replacement of the prevailing varieties of any given crop adaptive varieties will allow no additional cost to increase in the gross grain harvest. Comparative studies for six years (2008-2013) showed that the highest yielding spring crops in the Perm region on sod-podzolic medium cultured soils are barley and oats. Their average yield was significantly higher than that of spring wheat, respectively, 0.63 (25%) and 0.78 t/ha (31%). Estimation of parameters of the crop gives grounds for the conclusion that wheat has fewer compensatory opportunities to restore productivity of sowing under extreme conditions. Highest yielding crop in the Urals region is oats. The expansion of cultivation of spring wheat in the Central districts of the Perm region at the present time is unreasonable and leads to substantial loss of the gross grain harvest. When all the grain in the region with the exception of the seed fund is spent on animal feed and crop production uncompetitive similar products in the main areas of grain production, it is economically feasible to increase in the sowing area under barley oats and partially. The expansion of crops of winter wheat and triticale by reducing the acreage of spring wheat will increase demand for production of winter crops and to optimize the cr
op rotations. Optimal crop ratio for the Perm region is proposed. It is 40% for barley, and by 20% for winter cereals (1:1:1), spring wheat, oat. Adaptive varieties (wheats Krasnoufimskaya 100, Ikar, Ehkada 70, barleys Sonet, Rodnik Prikam'ya, oats Konkur, Krechet, Stayer) are recommended to be used.
