METHOD FOR CULTIVATION OF POTATOES WITH TRICKLE IRRIGATION Russian patent published in 2010 - IPC A01G1/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: method includes selection of precursor, hulling of precursor stubble, tillage of topsoil and subsurface horizon by depth of 0.40-0.45 m, application of organic fertilisers with norm of 60-80 t/ha, ploughing with soil overturning to close stubble remains and organic fertilisers for depth of 0.22-0.25 m, disking of upper layer with heavy disk harrows for depth of 0.12-0.16 m during motion along crown ridges, formation of trapezoid-shaped ridges in the last decade of September with height of 0.16-0.22 m, prevernal correction of ridges with rotor or cutter cultivators, removal of cold-resistant weeds in phase of "white threads", vernalisation of seed tubers, presowing treatment of seed tubers by biostimulators and inhibitors of pathogenic agents, planting of tubers on top of ridges and application of mineral fertilisers, arrangement of flexible watering pipelines with water outlets of trickle irrigation system, interrow treatment, vegetation watering, weed control in interrow spaces and on ridges, protection of tubers against wireworm and vegetative mass against Colorado beetle. To produce guaranteed crops of 80 t/ha of tubers, mineral fertilisers N₃₅₀P₁₀K₃₀₀ kg of reactant per ha are applied in portions with watering water from trickle irrigation system in the main phenological phases at the following ratios: from the appearance of sprouts to the beginning of reproductive organs formation (buds), 32-35% of nitrogen, 20-30% of phosphorus, 5-8% of potassium are applied, from the appearance of buds to blossoming - 43-60% of nitrogen, 40-45% of phosphorus, 22-28% of potassium are applied, from blossoming to withering of plant tops - remainders of nitrogen (10-13%), phosphorus (22-28%), potassium (63-64%) are applied.

EFFECT: method makes it possible to improve consumer properties of potato tubers and to reduce content of toxic substances in potato harvest.
