COMPREHENSIVE ASSESSMENT OF CORN HYBRIDS FOR SILAGE OF EARLY-RIPENING, MEDIUM-EARLY AND MID-RIPENING GROUPS IN THE CONDITIONS OF THE OREL REGION
In Russia, corn is the main silage crop. The requirements for corn for silo spreader are high yield, resistance to diseases, pests and temperature changes, as well as the ability to accumulate a large amount of solids. An important factor is the ripening time. The hybrids suitable for the climatic zone are chosen; early and mid-early hybrids are grown in the middle lane. The aim of the research was to increase effectively the production of silage corn in the Orel region, based on the variety changing, as well as a comparative assessment of corn hybrids for silage of different maturity groups of domestic and foreign selections, which ensure the production of high-energy corn silage, and optimization of harvesting terms in the conditions of Maloarkhangelsk district of the Orel region. An assessment of corn hybrids for silage according to economically valuable traits was given; the most adaptive hybrids to the climatic conditions of the region for use in the agricultural production of the region were chosen, a comprehensive assessment of corn hybrids for silage of three groups of ripening: early-ripening, medium-early and mid-ripening was carried out. In the conditions of the Orel region, for the production of high-energy silage during the harvesting of wax ripeness, it is necessary to replace old hybrids with new ones, the directions of use are universal or silage, which are included in the State Register of Breeding Achievements and approved for use in the Central Black Earth (5) region: from early ripe hybrids (FAO 160-180): Zolotoy pochatok 170 MW, from mid-early hybrids (FAO 200-280): Amello, Karolin, LG 31255, from mid-season hybrids (FAO 300-350): Mashuk 350 MV, Poesy KS.
