Abstract. Animal industries expansion in the forest-steppe zone of Trans-Ural has led to necessity of creation of a steady forage re- serve. For creation of the balanced forages, it is necessary to use corn grain. Corn cultivation in Siberia on grain technology is possible. It is promoted by creation of early hybrids. The aim of our study was to investigate the possibility of obtaining the corn in the forest-steppe zone of Trans-Ural. Researches were spent on leached chernozem. The experience scheme included two drains of crops on May, 15th and 25th and variants with application of fertilizers on planned productivity 4.0; 5.0 and 6.0 t/hectares of grain of corn. In experience, the hybrid Ladogskiy 148 (FAO 150) was sowed. The vegetative period of corn at crops has sowing on May 15th 132–137 days, displacement of terms of crops for the 3rd decade of May has provided vegetation reduction for 6–7 days. The greatest gain was observed in a phase of dairy ripeness of grain of corn where it made 11.05–16.49 t/hectares. Mixture of terms of crops for the 3rd decade of May has provided increase in this indicator at 22–31 %. Crops have provided on May, 15th receptions of planned productivity on all variants. At crops productivity decrease on 14–24 % concerning the first term on May, 25th was observed. Corn cleaning on the first term of crops spent at humidity of grain of 34.4–34.8 %. Displace- ment of terms of crops for the third decade of May has tightened process of maturing of grain, therefore cleaning was conducted at humidity on 1.9–4.0 %, concerning the first term of crops.
Keywords: corn, mineral fertilizers, the vegetative period, corn biomass, productivity.
