Ecological and biological assessment of eastern galega (Galega orientalis Lam.) as a prospective crop for introduction under the conditions of the city of Surgut

Extreme climatic conditions in Surgut and city development on bulk substrates, exposed to con-stant water and wind erosion, determine the neces-sity of new plants introduction. Introduced plants shall demonstrate wide ecological plasticity, valua-ble biological and biogeocenotic properties which enable them to adapt to severe soil and climatic conditions of the region. Eastern galega (Galega orientalis Lam.), a perennial bean crop, may be-come prospective for resolving these issues. The results of primary assessment of introduction of Galega orientalis Lam. 2-nd and 3-rd year of life (the grade of Gale) in the conditions of Surgut Re-gion of Khanty-Mansi Autonomous Region - Yugra are presented in the study. It was established that eastern galega will completely acclimatize in the conditions of introduction. Plants entered the phase of blossoming and fructification for the 3-rd year of vegetation at the sum of the effective air tempera-tures above 10 °C =1034-1563.4 °C. Binary crops of eastern galega with peas in general rendered negative after-effect on growth and development of plants in two years of researches. The reduction of density of herbage, the height of shoots and the length of the main root by 20-54 % decreasein productivity by 65-84 %, leaf forming and the ac-cumulation of underground biomass - by 1.5-2 times was observed, FSP was 2-5 times lower. The introduction stimulated with Baikal-EM1 the adaptation potential of plants to soil climatic condi-tions of the region of cultivation. The increase in all morphometric indicators, photosynthetic potential, biological and seed efficiency of plants was noted. On the basis of the obtained data it is possible to recommend introduction of eastern galega both in pure crops, and with use of microbiological Baikal-EM1 fertilizer for inoculation of seeds crops. The introduction of eastern galega in Surgut will allow expanding the range of perennial plants with wide ecological potential used for gardening of the city.
