In the continental climate of the southern Urals, rapeseed compares favorably with many forage and traditional silage crops with a high protein content and adaptive properties. The cultivation of rapeseed guarantees the production of its own seeds, up to 40 percent of oil, 60 percent of cake and 98 percent of rapeseed flour. (The research purpose) The research purpose is in improving the efficiency of rapeseed cultivation and rational use of rapeseed seeds, rapeseed flour and oil in the agricultural production in the Chelyabinsk region. (Materials and methods) The influence of various forecrops on the productivity and quality of spring rape seeds in the links of grain-pair crop rotations in the Northern forest-steppe of the Chelyabinsk region were studied. Authors have analyzed the chemical composition of the soil and seeds of spring rape after various forecrops. (Results and discussion) The article proposes to reduce energy costs during pressing and reduce residual oil in the cake after pre-grinding of rapeseed by cutting method using a centrifugal-rotary shredder. The article shows that rapeseed flour has a good flowability and is easily mixed with other feeds. It was found that partial replacement of concentrates with rapeseed flour in the amount of 8-12 percent of the total weight in the diet of lactating cows contributes to an increase in milk productivity by 1.1-1.8 kilograms in terms of milk of 4 percent fat content. (Conclusions) It has been revealed that in order to increase the yield and quality of spring rape seeds, it is necessary to place them on the best forecrops. It was found that when 75 percent of rapeseed oil is mixed with 25 percent of diesel fuel, the obtained biodiesel is not inferior to diesel in terms of energy indicators. The article proves that when cultivating rapeseed for seeds on an area of 100 hectares, it is possible to produce 94.5 tons of biodiesel fuel, 106.0 tons of cake with an oil content of 5 percent and 8.4 tons of oil sludge, the estimated economic effect after sale is of 3,813,325 rubles.
