Abstract:

The article considers the dependence of crop yield from the weather and cycles of solar activity in the Tyumen area, the Tyumen Oblast. The article performs a statistical analysis of the dynamics of crop yields from 1956 to 2002 and the peculiarities of weather conditions and the cycles of solar activity. Hypothesis of the research: weather-climatic conditions influence the dynamics of the yields of grain crops. Cyclic variations of solar activity influence on the frequency of occurrence of weather-climatic situations. The practical results can be used for creation the algorithm of the risk management in the agricultural sector.
