Yield and quality of green mass of winter crops, depending on the mowing time

Abstract

The relevance of the study is conditioned by the fact that the normalized feeding of farm animals is impossible without knowledge of the complete chemical composition and nutritional value of feeds grown in the specific conditions of the region. The main purpose of the research was to determine the difference and advantages of productivity and quality of green mass of triticale from those of rye and wheat, depending on the mowing time. The study of the green mass of winter crops was carried out on the fields of the Samara Research Institute of Agriculture during 1996 to 2005 and 2016 to 2018. The yield and quality of varieties of winter rye, winter soft wheat and winter triticale of local selection have been studied in the experiments. The studies were conducted in four repetitions. It was carried out the biochemical evaluation of the samples. Plant sampling and chemical analysis in the green mass of plants were carried out according to the available state standard (GOST). Comparison of the feed value of winter crops was carried out according to development phases. Nutrition indicators: the content of protein, sugar, fiber, fat, nitrogen-free extractable substances, carotene, as well as feed units, and digestibility have been studied in this research. It was concluded that triticale is a worthy culture for use in the production of high-quality grain-haylage feed.
