Soil scientists of complex expedition of the Academy of sciences of the USSR in 1925-1926 have considerably expanded the geography of studying of soils in Yakutia with scope of foothills and mountains of the Verkhoyansk ridge, and also with an outlet to border of northern taiga. The basic laws of formation of a soil cover and regional features of soils have been revealed, the detailed characteristic of genesis, structure and properties of soils of different types of landscapes is given. The first survey soil maps of the investigated territories have been made and recommendations on development of ground resources of an agricultural zone of republic are given. The material saved up by them in the subsequent has been used at drawing up of soil maps of different scale, and practical recommendations have underlain accommodation of the agricultural enterprises and experimental stations.

High biological efficiency of nematode preparations in conditions of frozen earth in the Central Yakutia is shown for the protection of cabbage against the Summer Cabbage Fly (47.2-66.7%). The Use of Entonem-F with rate of application 250 thousand nematodes/plant has provided increase of productivity by 26.29 t/ha. The conditional net profit has reached 235.2 thousa.nd roubles/ha after the preparation application, and economic efficiency has reached 28.4%. Efficiency of entomopathogenic preparations is higher, than efficiency of chemical preparation Decis used. Besides Steinernematides have not conceded by this parameter to Basudin, the insecticide of systemic action. Preparations Nemabakt and Entonem-F are recommended for wide testing and subsequent inclusion in ecologically safe systems of plant protection in the Central Yakutia

The results of an experimental research of hematological parameters of Simmental heifers, which were fed with or without mixed fodder in conditions of the Central Yakutia are given. The data on blood biochemical composition and parameters of natural resistance are got. A wide range of stages of cattle blood composition formation in conditions of feeding and breeding is defined. It is showed, that during the heifers’ growth period up to 18 months under the influence of feed and adaptation factors the change of hematological parameters occurs, among such parameters are: hemoglobin, erythrocytes, leukocytes, macro- and microelements, vitamins, amino acids, protein fractions and natural resistance.

The article presents main results of comparative growth study and development of young animals, some biological features of local breeds: Yakut, Simmental and imported Kalmyk breed of cattle in Yakutia climate. The work was carried out in the subsidiary farm of the Yakut State Agricultural Academy. Experimental population consisted of 45 heads of bull calves, selected according to the method of pairs - analogues. We studied the technology of keeping and feeding, growth and development, the morphological and biochemical composition of blood, the physiological state of bull-calves of different breeds. Young animals (experimental group) energy growth was studied by the standard zootechnical method, which is weighing in every 3 months; hematological parameters were determined by hematological analyzer PCE-90Vet; total protein in the serum of blood was determined by a refractometric method; protein fractions - by electrophoresis method in the Yudelovich modification (5 heads from a group). The more intensive diurnal growth (increase) was established in the group of imported Kalmyk breed, which ensured the growing of bulls in this group by 20-30 kg alive weight than in peers (Yakut and Simmental cattle) at the same age. Young growth of Kalmyk cattle was distinguished by hypoalbumin and hyper gamma-2 globulin fractions of protein metabolism, which reflects the functional activity of their immune system in the conditions of the region.

In conditions of the Middle Lena valley, a growth regulator was used for the first time as a stimulant, which increases the germination of seeds, stimulates the initial growth ofplants, promotes resistance to diseases and generally improves the adaptability of perennial grasses in the first years of life. In the studies, the growth stimulator Krezacin was used. "Krezacin" (trekazin, irkutin) is an immunostimulant, adaptogen of a new generation. It is usedfor active rooting and strengthening ofplant immunity in the first years ofplant life. The mechanism of its action is based on optimization of biosynthesis of proteins, nucleic acids, enzymes. The preparation acts on the cellular level and activates adaptive reactions of plants. The studied areas of field experiments were located in the Middle Lena valley at the scientific station ҺMarkhinskyһ of the Institute for Biological Problems of Cryo-lithozone of the SB RAS, located 13 km away from Yakutsk city. For the first time in the conditions of cryogenic floodplain layered soils, the influence of the growth stimulant Kresacin on linear growth, productivity, shoot formation and the structure of shoots of a smooth brome of the variety SibNIISKhoz-189 was studied. Over the years of study, it was proven that an effective dose of a growth stimulant Krezacin is 75 ml /10 l. Three years studies have established that soaking of smooth brome seeds with Krezacin in a given dose promotes an increase in the linear height of smooth brome up to 110.8 cm, the productivity of the above-ground mass by 2 times, an increase in the number of generative shoots by 1.8 times, vegetatively elongated shoots by 2.3 times and vegetatively shortened ones by 1.6 times. At the same time, the mass of one generative shoots of smooth brome is 3.5 g, which exceeds the control by 16 %, which indicates the maturity and usefulness of the sown phytocenosis.
