METHOD OF GROWING POTATOES USING DIFFERENTIATED IRRIGATION MODES IN CONDITIONS OF UNSTABLE MOISTENING ZONE OF STAVROPOL TERRITORY Russian patent published in 2024 - IPC A01B79/02 A01G22/25 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to potato growing. Method includes autumn peeling of precursor to depth of 0.06-0.08 m with introduction of nitroammophoska N_60-90P_90-120K_60-120, winter ploughing to different depths with alternation by years - in the first year to depth of 0.20-0.24 m with a bed turnover to the same depth, and in the second year to a depth below the plough bottom by 0.08-0.10 m and formation turnover by 0.20-0.24 m, spring harrowing, pre-sowing cultivation of soil to depth of 0.1-0.15 m with cutting of ridges in a circle with an “МТЗ-1221” and “КРН-4.2” unit and application within 3-4 days after planting of herbicide zenkor with consumption rate of 1.6 l/ha, further with the same herbicide with consumption rate of 0.8 l/ha, treatment of potato plants with tops height of 5 cm, as well as treatment with insecticide confidor 0.04 l/ha + fungicide tanos, 0.6 l/ha and inter-row treatment after each watering. Potato tubers are planted in ridges with simultaneous application of fertilizers in a circle with an “МТЗ-1221” + “Л-202” unit. Planting density is 55 thousand bushes per 1 ha and planting depth of 6-10 cm. Ammophos 50 kg/ha is applied during potato tubers planting. Pre-emergence tillage is carried out by means of “МТЗ-1221” and “КРН-4.2Г” unit at 0.12-0.14 cm, and differentiated and intensified irrigation by sprinkling machine "Pivot" in layer of 0-4 and 0-6 m to maintain soil moisture at level of 60-70 and 70-80% of field moisture capacity depending on the growth phase. At that, plants are also hilled with “МТЗ-1221” and КРН-4.2Г unit, and tops are removed by mower-grinder “КИР-1.5Б”. Height of the tops cut is 20 cm; the potatoes are harvested with an “МТЗ-1221” unit and a potato digger “КТН-2ВМ” as the tubers ripen.

EFFECT: method provides increased yield of spring planting potatoes in the area of unstable moistening, using accurate calculations of crop water consumption by growth phases with economical, differentiated irrigation mode.
