Spring rye, or yaritsa, is a cereal crop and belongs to the spring cereals of Group I.
Spring rye is cultivated in small areas in areas of Eastern Siberia characterized by severe autumn droughts and harsh winters. It is inferior to winter rye in height and yield stability. It is not demanding to the soil and climatic conditions, grows well on the light sandy loam, strongly ashed and acidic soils, as well as on drained peatlands.
The variety of spring rye Onohoyskaya was bred by the Buryat Agricultural Experimental Station. It is mid-early, drought-resistant, prone to lodging and shattering. Yield is superior to local Siberian varieties. Alloted in Buryatia, Tuva, Yakutia, Irkutsk and Chita regions.
The agricultural technique of spring rye cultivation is similar to that of other early spring cereals. The best precursors are row crops and leguminous crops.
Norm of the full mineral fertilizer is 30-40 kg/ha of NPK. Early sowing terms are optimal. With the usual method of seeding row crops seeding rate is 5-7 million/ha of germinated seeds.
Care for crops includes harrowing in tillering phase across the rows in 1-2 trails.
Harvesting is carried out mainly in two-phase in the phase of wax ripeness of grain.
