Weather factors impact on the formation of the crops cereals in Kharkiv region

Impact of weather-climatic conditions on vegetation and crops cereals and, in particular, the winter wheat is examined. After the analysis of the statistic indicators of the crop capacity of winter wheat and the weather conditions in Kharkiv region in 1975-2012 was performed, it was shown that the longest intensity of droughts and hot winds phenomena are observed every three years, catastrophic ones every 10 years. The crops of winter wheat were less than 20 kg / ha. Methods of mathematical statistics have shown the solution to the problems of relation between the crops and weather conditions. The physic-statistical model of the relation of the cereal crop with the natural factors was created. This gives the possibility to estimate the natural resources of cereals growth and to determine the conditions of crop formation. The discovery of quantitative relation of the crop with the weather factors permitted to calculate crop in every case and to forecast the yield.
