EFFECT OF WEATHER CONDITIONS ON YIELD OF SPRING WHEAT IN CISBAIKALIA
There have been presented the results of the studies on the correlations between indicators of field germination, plants preservation, yield and performance of weather conditions in Cisbaikalia according to the heat moisture content in spring wheat plants in the steppe, forest-steppe and sub-taiga zones. The problem of improving the system of agrolandscape system of seed growing is discussed. Field germination of spring wheat variety in the plots of Cis-Baikal was in the range from 56.0% in steppe zone and to 93.0% in the sub-taiga. If one compared these figures in the zones, the field germination in steppe zone by years ranged from 56.0% to 67.0%. The average field germination of seeds during 11-year period of observation in this area amounted to 90.0% from the laboratory. This is a very high rate, indicating that the moisture content of soil in this period was optimal for germination of plants. The correlation coefficient was 0.508. In the steppe zone, this dependence was less and the ratio was equal to 0.405, while in the sub-taiga zone the correlation coefficient was on average 0,608.
