METHOD OF CULTIVATING SPRING WHEAT, PREFERABLY - IN LIGHT-CHESTNUT SOIL ZONE OF LOWER VOLGA REGION (VERSIONS) Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: proposed method envisages the forecrop harvesting, stubble ploughing and autumn-time application of organic and mineral fertilisers. The mineral fertilisers applied are phosphorus-containing and potassium ones, the dosage being equal to 15-20 kg of primary nutrient per hectare (in terms of phosphorus content) and 10-12 kg of primary nutrient per hectare accordingly. Nitrogen-containing fertilisers are applied immediately on the ground surface, the dosage being equal to 30-36 kg of primary nutrient per hectare. The other operations additionally envisaged are: real tillage, weed plants removal, herbicide agents application, seed inoculation in a 1.2-1.3 t/m³ dense brine solution of the bischofite natural mineral, sowing and post-sowing compaction. The proposed method provides for variants of pre-introduction treatment of seed of spring wheat promising varieties depending on the available cultivation conditions. In case of spring wheat being cultivated in localities with a hydrothermal index no more than 0.2 the seeds to be introduced are treated with a tank mixture composed of brine solution of the bischofite natural mineral (expenditure rate = 6-10 l per ton of seeds) and "Mizorin" bacterial preparation (expenditure rate = 200-300 g per ton of seeds) 1-8 hours prior to being planted. In case of spring wheat being cultivated in localities with a hydrothermal index amounting to 0.2-0.4 the seeds to be introduced are treated with a tank mixture composed of brine solution of the bischofite natural mineral (expenditure rate = 6-8 l per ton of seeds) and "Agrophil" bacterial preparation (expenditure rate = 150-250 g per ton of seeds) 6-12 hours prior to being planted. In case of spring wheat being cultivated in localities with a hydrothermal index amounting to 0.3-0.6 the seeds to be introduced are treated with a tank mixture composed of brine solution of the bischofite natural mineral (expenditure rate = 7-12 l per ton of seeds) and "Flavobacterin" bacterial preparation (expenditure rate = 260-380 g per ton of seeds) 10-16 hours prior to being planted. The tank mixture is prepared by dissolving the biological preparation and the bischofite natural mineral brine solution in 10 l of main water at a temperature of +18...+26°C. The seeds are pre-treated in the semi-dry thorough mixing mode during 2-3 hours to be subsequently planted within 1-2 days at a soil temperature no less than +5...+6°C.

EFFECT: guaranteed sprouting; sustainable growth and development of crops and increased yield of grain.
