In the article, in the conditions of long-irrigated light gray soils of Surkhandarya region, the mid-ripening potato varieties "Sante" and "Yaroqli-2010" have two reproductive seed nodules, two cultivation methods, two row widths and three maintenance measures. In the scheme of 90x15 cm, an additional device is installed on the "Amak" tiller-cultivator or KRN-2,8A cultivator, 1st time 18 cm, 2nd time 23 cm deep, leaving a protective zone of 8-10 cm and softening and furrowing, the highest grade (25.3- 32.7 t/ha) and seed yield (13.4-17.9 t/ha) and 2.4-5.4 mln. per hectare. soums of net income and 11.8-21.5% additional profitability level increased, in the conditions of Surkhandarya region, a convenient planting method of growing potato varieties as double-cropped and double-cropped crops, as well as the effect of different methods of inter-row processing on soil physical properties in the care of potatoes information on.

Light-colored gray soils of Surkhandarya region that have been irrigated since ancient times,

According to B.F. Khlevnoy and others, it is noted that 52 thousand buds are required for one hectare if there are 5 sprouted eyes on average. If the weight of tubers is 60 grams, this is 31.2 ts/ha (B.F. Khlevnoy et al., 1986).

According to N.N. Balashev, in his data, it was noted that their biological characteristics and growth conditions are also taken into account when determining the optimal plant thickness in potato cultivation (N.N. Balashev, 1963).
