As the productivity of crops depends on the weather conditions, their analysis is of scientific and practical importance. According to the results of statistical and analytical materials of weather station Uman, 2011 – 2012 crop year for the entire period of observation has the longest summer weather regime (five), autumn, winter and spring, respectively, four, one two months. Set records of the maximum temperature for June +36,2 ° C (22.06) and August 37.6 (7.08), and 46 days where the temperature is +30 ° C and above.
The amount of precipitation was on 181.2 mm less, and the average temperature is on 2 ° C higher than the traditional long-term average.
Despite the fact that for the formation of the future harvest rather discouraging conditions prevailed in Uman district, winter grain crops: wheat and barley crops formed the yield at the level of respectively 47.4, 38.6 t / ha, and the spring 21.2, 32.0 kg / ha. Corn yield was 51.8 t / ha, peas – 22.5; soybeans – 12.0; sunflower – 23.7 and beet sugar – 333 kg / ha. In comparison with 2011 yields were lower then follows: winter grain on 9%, sugar beet – 21; soybeans and corn – 45%, and the sunflower, as drought resistant crops received on 17% higher.
