Purpose. Creation of optimal conditions for the formation of maximum productivity and quality of the main and by-products of corn hybrids based on the improvement of such elements as sowing timing, fertilizer system, seed preparation and sowing, which will ensure the possibility of its processing to produce alternative fuels (bioethanol and biogas) for environmental safety and energy autonomy of rural communities
Specifications. Recommended technology elements: – selection of hybrids with high yield potential of the mid-early and mid-ripening ripeness group; sowing at a soil temperature at a seeding depth of +8°C; carrying out foliar fertilizing with microfertilizers and bacterial preparations in the phase of 5-7 and 10-12 leaves of corn; introducing into the main fertilizer bioorganic fertilizers based on digestate, obtained by anaerobic digestion of pig manure at a rate of 55 t/ha; use of medium and large fractions of seeds; planting seeds to a depth of 7-8 cm.
Application area. Agriculture. Agricultural companies, biogas stations, alcohol factories, scientific institutions. The development of a concept for ensuring energy security and energy efficiency as priority areas for sustainable development of rural areas is applicable to farms that grow corn and have the opportunity to use biogas stations, distilleries that have the ability to process corn grain into bioethanol.
Advantages. Compared to existing technologies for growing corn, the developed technology makes it possible to obtain maximum grain and silage productivity of corn through an integrated approach to the use of the most important elements of technology (selection of hybrids, sowing dates, seeding depth, preparation for sowing, fertilizer system). In addition, the developed technology has significant environmental safety for the environment, since it provides for the possibility of using digestate in the fertilizer system.
Technical and economic effect. The introduction of technology will make it possible to obtain high yields of grain (10-14 t/ha) and silage (50-60 t/ha) corn with optimal use of the bioclimatic potential of the growing area, effective use of intensification means, which will improve the quality of the resulting products and, accordingly, will allow for their processing to obtain alternative fuels The use of digestate in this technology allows reducing the use of mineral fertilizers by 30-40%.
Description. The technology for modeling the cultivation of corn for grain to obtain alternative types of fuel provides for: the use of early sowing at a soil temperature of 8C, the use of mid-early and mid-ripening hybrids with a large fraction of seeds that are immersed to a depth of 7-8 cm, foliar fertilizing containing zinc with the bacterial preparation Biomag + in the phase of 5-7 and 10-12 leaves and the use of bioorganic fertilizer based on digestate obtained by fermenting pig manure in biogas stations at a rate of 55 t/ha into the main fertilizer, ensuring maximum realization of the genetic and biological potential of hybrids. by increasing yields by 20-40%, improving grain quality and creating the opportunity to process part of the products to produce alternative fuels (bioethanol and biogas).
