Oilseed flax and alfalfa as sources of nutrient elements in the Central region of non-chernozem zone of Russia

Abstract

The article presents the results of research for the year 2022. The objects of the research were oilseed flax and alfalfa. Percentages of crude protein, fiber and ash elements were evaluated in the crops. The content of nutrient elements was estimated by infrared spectrometry. In flax the content of the studied elements in seeds was estimated, in alfalfa the content of nutrient elements in green mass after the second cutting was estimated. Among oilseed flax samples, the highest raw protein yield was provided by Raduga variety (3.40 c/ha), it also provided the highest ash element yield among flax samples (0.92 c/ha), and Nilin variety provided the highest fiber yield (2.24 c/ha). Among alfalfa samples, sample Taisia (152.15 c/ha and 154.44 c/ha, respectively) showed the highest values for raw protein and fiber collection, while sample Agnia (54.90 c/ha) was the leader in ash elements collection.
