Abstract

A method for growing early potato under agrofiber comprises germinating propagation tubers, potato varieties, planting dates, a plant arrangement scheme, soil level profile. Seed tubers of potato of early-ripening varieties of mass of 50-80 g are germinated in combined manner: at first 20 days at a temperature of +18…+20 °C in the light, and then 7-10 days in moist environment at the same conditions, they are planted according to the plant arrangement scheme of 70×25 cm at a depth of 8-10 cm with the simultaneous ridging of rows, the planting date is the second half of March. In doing so four formed ridges are covered with the agrofiber of 50-100 m in length, 3.2 m in width and 19 g/min density, and the edges of the agrofiber are fixed on the surface by a soil layer along the perimeter in 0.5 m. At a height of potato of 15-20 cm one edge of the agrofiber is made free of the soil and it is opened, ridging of the plants is carried out, the covering material is covered and fixed, it is removed after the threat of frost return (the first decade of May) had passed.
