Abstract

The purpose of this study is to establish the most suitable components in terms of productivity and quality for the effective cultivation of a binary vetch-and-grass mixture for the purpose of further harvesting haylage from it. The studies were carried out on winter crops: vetch + wheat and vetch + triticale; the soils are represented by leached, low-humus, powerful chernozems, located in the conditions of the alluvial-loess plain agricultural landscape of the Western Ciscaucasia (Krasnodar Territory) with plowed steppes. The subjects of the study were: Triticum aestivum L. variety of Tanya; Triticosecale Wittm. ex A. Camus variety of Khleborob; Vicia pannonica Granz varieties of Chernomorskaya and Orlan; Vicia vilossa op Roth varieties of Lugovskaya-2 and Glinkovskaya. Two cuttings were studied in different phenological phases. According to the results of the study, when mowing in the first ten days of May, the most productive grass mixtures are winter wheat of Tanya + Hungarian vetch of Orlan (green material – 102.6 c/ha, dry weight – 19.7 c/ha) and winter triticale of Khleborob + downy vetch of Glinkovskaya (100.2 c/ha of green material and 20.0 c/ha of dry mass). According to the results of laboratory studies, the most nutritious grass mixture was based on winter triticale and downy vetch.
