Application of intensive technology of cultivation of spring wheat for seeds in of the Krasnoyarsk forest-steppe

The results of agroecological monitoring on the improvement of intensive technology for cultivating spring wheat of Kanegirskaya 89 and Novosibirsk 29 varieties in 2016-2018 at the experimental site of Emelyanovskoye LLC. Soil - chernozem leached with a humus content of 8.3 %. On experience in Minino of the Emelyanovsk district, the soil is represented by ordinary chernozem, the content of humus is within 8.5 %. Kantegrskaya 89 wheat sowing was carried out by sowing SZP-3.6. Seeding time May 10-15 depth 6 cm. Seeding coeffi5.5. At the hospital in Minino, sowing was carried out on May 27, with a norm of 3.5 million germinating grains per 1 hectare to a depth of 6-7 cm by sowing SZS-2.1. Soil moisture content to sowing in layer 0-50 cm was 32 %. Provision of nitrate nitrogen during vegetation corresponds to the 2nd class. Protection of plants from weeds consisted in treating crops with a tank mixture of Puma Super herbicides (0.4-0.6 l/ha) + Magnum (8 g/ha). Cantegrate 89 was formed under conditions of suffi humidifi at a favorable temperature regime, which ensured a yield of 2.9-3.7 tons/ha (HSR 05 = 0.84 tons/ha). Novosibirsk 29 wheat formed 2.6-3.2 tons/ha (NSR 05 = 0.5 tons/ha). The lower yield is explained by the smaller number of stems.. Thus, conditions (climate, weather, soil) have a stable natural potential, mainly determining the choice of crop, variety and technology for their cultivation. Technology is the most variable factor that has a wide range of changes, associated with anthropogenic factors and directly dependent on conditions. To improve technological processes in intensive agriculture, it is advisable to take into account natural conditions and variable factors that form intensive technology and affect crop productivity.
