Abstract

The development of animal husbandry in Siberia has led to the necessity to form stable fodder base at the expense of domestic products. Many producers and scientists consider the corn as the most promising culture. It is the integral component at the creation of a high-energy forage for farm animals and birds. High content of nutrient elements in corn kernels and the content of nonreplaceable amino acids turn this culture into a main element in feeding animals. The aim of the research is to study the producing corn kernels in the forest-steppe zone of the Trans-Ural region. The investigations were carried out in the leached loamy black earth area with characteristic morphological features and properties for soils in the South of the Tyumen region. The scheme of the experiment included two sowing dates on May 15 and on May 25, and options with various level of feeding for planned yield 4.0; 5.0 and 6.0 t/ha of corn kernels . In the experiment the hybrid Ladozhskyi 148 was sowed (FAO 150). The vegetation period of corn at sowing on May 15 was 132-137 full days, shifting the sowing date to the 3rd decade of May has provided the reduction of this period by 6-7 full days. Its greatest gain was observed at a milk stage of corn kernels where it was 11,05-16,49 t/ha. Shifting the sowing date into the 3rd decade of May has increased this indicator by 22-31%. Seeding crops on May 15 allowed to obtain the planned yield in all options. When seeding crops on May 25 there was a decrease in yield by 14-24% in comparison with the first term. Harvest humidity of corn kernels at the first sowing date was 34.4-34.8% of weight. The disbalance of feeding elements in variant with the planned yield of 5.0 t/ha of corn kernels has led to increasing humidity up to 38.9%. Shifting sowing date to the third decade of May has increased the indicator by 1.9-4.0% in regards to the first sowing date.
