PRODUCTIVITY AND UNDERGROUND MASS OF MEADOW PLANTS IN CONDITIONS OF THE INDIGIRKA RIVER BASIN

abstract 1481904018 issue 148 pp. 130 – 141 30.04.2019 ru 82
For the first time results of researches on potential productivity and environmental role of hayfields in the Indigirka river basin (Momskiy district) are presented. Researches proved that feeding meadow plants in conditions of the Indigirka river basin, depending on the type of vegetation, location and features of root systems, provide maximum crop productivity – up to 18,5 dt/ha of hay with productivity of 1 ha for harvesting exchange energy up to 16,1 gigajoule, fodder units 1130 and crude protein up to 209 kg maximal underground mass accumulation of meadow plants was formatted in the region of Indigirka and Khonuu – mixed and squirreltail barley (hordeum jubatum) hayfield up to 193,6 dt/ha, dry matter and carex duriuscula and squirreltail barley hayfield up to 252,2 dt/ha with the majority of roots in layer 0-10 cm. up to 76-88%. Field of Khonuu, with mixed and squirreltail barley hayfield, contained underground nitrogen – up to 33 kg/ha and labile phosphorus – up to 71 kg/ha. Increased accumulation of labile phosphorus root mass provides enhancement of cold resistance ability in conditions of the subarctic zones of Yakutia

SPECIAL ASPECTS OF THE INITIAL STAGE OF BERGENIA CRASSIFOLIA L. CLONAL MICROREPRODUCTION IN VITRO IN YAKUTIA

abstract 1211607050 issue 121 pp. 860 – 868 30.09.2016 ru 499
Along with traditional ways, the biotechnological methods become more significant in contribution to plant conservation in situ. The work is dedicated to elaboration and advancement of the method of isolated tissues and organs culture for conservation and reproduction of the badan, Bergenia crassifolia L., the rare species of Saxifrgaceae family. The conducted study yielded the regenerated plants of B. crassifolia from seeds. For the first time, we have performed conservation and reproduction of B. crassifolia in vitro under conditions of Yakutia

SPECIES COMPOSITION AND EFFICIENCY OF STEPPE MEADOWS IN DEPENDENCE ON THE DIETARY REGIME IN THE CONDITIONS OF CENTRAL YAKUTIA

abstract 1311707057 issue 131 pp. 672 – 683 29.09.2017 ru 152
In the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food
