Prospects of eastern galega (Galega orientalis Lam.) cultivation on podzolic soils of Western Siberia middle taiga (in conditions of Khanty-Mansi autonomous area - Yugra)

The results of three-year introduction studies of Eastern Galega ( Galega orienta- lis Lam.) planted on technogenic disturbed lands in the middle taiga of West Siberia are presented. Eastern Galega biological and biogeocenotic properties are studied for the first time for this territory. The research results revealed the effective adaptation mechanisms of the species to extreme edaphic and climatic conditions. The possibility of effective introduction of Eastern Galega into the region as a sidereal and highly nutritious forage crop is established. By the end of the third year of the species vegetation the humus content in the arable horizon ranged from 6.0% to 7.4% compared to 5.0% control value. P2O5 content was within 293-374 mg/kg, exchange potassium - less than 50 mg/kg, soil solution reaction - 4,0-5,3 рН units. Galega herbage yield was 60-470 centner/ha. Crude fiber content in the studied specimen amounted to 23-28 %, crude fat - 2,5-2,9 %, crude ash - 7,2-8,1 %, crude protein - 12,3-16,2 %, digested protein per 1 feed unit - 112-123 g, metabolizable energy - 9,4-10 MJ/kg, 0,7-0,8 feed units per 1 kg of dry matter; all above indicate high feeding value of this crop specimen.
