The influence of growth stimulator on specific structure and productivity of alfalfa and awnless brome grass mix in the conditions of middle-taiga subzone of Yakutia

In the conditions of Namtsy's agrolandscape of middle-taiga subzone of Yakutia growth stimulator "Krezacin" which increased germination of seeds had been applied for the first time, it increased linear growth of plants, promoted the adaptation to adverse conditions and increased productivity. The increase of adaptation of growth of seeds and their survival in the first years of life by processing of plants growth factors during crops that was especially important in the conditions of middle-taiga subzone of Yakutia with short vegetative period, dryness in the second half of summer and poor permafrost soils made up the basis for the researches. The researches were conducted on research hospital "Markhinsky" of the Institute of Biological Problems of Cryolithozone of SB RAS located in 13 km from Yakutsk. For the first time in the conditions of permafrost meadow and chernozem soils influence of growth factor of «Krezacin» on linear growth, specific structure and productivity of alfalfa and awnless brome mix had been investigated...
