ENVIRONMENTALLY FRIENDLY METHOD OF POTATO CULTIVATION Russian patent published in 2015 - IPC A01B79/02 A01G1/00 

FIELD: agriculture.

SUBSTANCE: method comprises placing a potato on the predecessor, disking, fall-ploughing the soil, spring cultivation, preparation the seed material two weeks before planting by air-thermal heating to pipping of sprouts, cutting ridges, processing of tubers with microbiological preparation and planting tubers, inter-row treatment at finding weeds in the stage of "white string" with the gradual increase in the ridges. The first inter-row treatment is carried out after the emergence of potato sprouts, the subsequent second and third row treatments - with an interval of 10-12 days prior to the closing of potato tops. Protection of potato plants from pests is carried out using microbial agents by spraying the tops during the growing season in dry calm weather, pre-harvesting mechanical removal of the tops and harvesting potatoes is carried out. At that planting tubers is carried out on a smooth surface of soil after deep cultivation to a depth of 20-22 cm in rows with spacing between them of 90 cm to a depth of 4-6 cm with a planting density of 50000 tubers per hectare with simultaneous treatment of tubers and the bottom of the furrow with 5% solution of Phytosporin-M at the rate of its consumption of 10 litres per 1 ton of planting material by spraying with a nozzle. Cutting the ridges is carried out simultaneously with the first inter-row treatment, forming a ridge with the height of 25-30 cm and the width of 17-18 cm on top with the ridge-forming cutter with active working bodies. The second and third inter-row treatments are carried out with a simple ridge-forming cutter. In addition, protection of potato plants from pests is carried out once with 0.01% solution of Phytoverm-M at the rate of its consumption of 500 litres per 1 ha.

EFFECT: method enables to obtain the yield of food potato with high consumer properties against the background of complete elimination of chemical means of plant protection from diseases and pests by environmentally friendly methods and means of weed control, preventing pollution the environment and potato crop with toxic substances.
