CROP YIELD OF SPRING WHEAT VARIETIES OF OMSAU SELECTION IN CONTEXTS OF CHANGEABLE CLIMATE OF THE SOUTH FOREST-STEPPE IN THE WESTERN SIBERIA
Abstract
The article is devoted to the aspects of climate warming and crop yield of spring wheat. It shows correlation coefficients of grain crops with average daily temperature and precipitation in each month of the year when sowing in different periods from 1970 to 2012 in the south forest-steppe of the Western Siberia. The paper analyzes data on changing maximal and minimum average daily temperature and average monthly precipitation for almost 50 years (from 1961 to 2009) in Omsk region. The authors reveal data on average daily temperature and total precipitation in decades by means of Omsk hydrometeorological station observations from 1971 to 2013. The publication defines tendency in changing climatic factors and crop yield of spring wheat in the south forest-steppe of the Western Siberia. It calculates contingency of climatic factors with crop yield of spring wheat in strain testing of OmSAU and Moskalenskoe SAA. The research shows reducing of general crop yield of spring wheat due to climate warming and therefore affection increasing and epyphytotic periods appearing. The research is aimed at strategy development of further spring wheat selection in the Western Siberia.
