Features of formations the harvest of fodder beans and soybeans in subtaiga zone conditions in Western Siberia

The research of fodder beans Siberian in 2005-2013 and soy of SIBNIIK 315 in 2004-2013, carried out in subtaiga zone of Omsk Region on gray forest soils, showed that the duration of interphase and vegetative periods of fodder beans and soy was reduced at the increase of average daily air tem-perature and tightened at the increase in the sum of precipitations. Thus, the period of duration "shoots - full ripeness" in fodder beans in crops and their full maturing was from May, 10 to May, 20 identical and made 102-103 days. At soy this peri-od was the shortest in crops on May, 15 and 20 and made 98 days. The productivity of grain of fod-der beans increased at the increase in the rainfall and made 2.43-3.98 t/hectare in 59 % of cases at loss of 89.1-163.8 mm for the period "the begin-ning of blossoming - maturing". Soy productivity of grain depended on average daily air temperature for the period "blossoming - maturing", was higher (1.82-2.81 t/hectare) it was at the average daily air temperature of 15.4-19.4 °C in smaller quantity of cases (26 %). The highest productivity in fodder beans (2.88 t/hectare) was in crops on May, 15, and soy (1.72 t/hectare) - in crops on May, 10-15. Protein content in grain of the studied cultures de-pended on the average daily air temperature and the sum of precipitations. It was the highest in crops on May, 10-15. Thus, optimum terms of crops of fodder beans and soy for cultivation on grain in subtaiga zone of Western Siberia is on May, 10-15 as there are optimum conditions for the formation of a big crop of qualitative grain of fodder purposes.
