Presprouting of seed potato accelerates shoots for 7-10 days in dependence on variety of potato and the covering with spanbond - for 1-2 days. Presprouting of planting material has provided commodity productivity for 40-45 day after shoots from 18,3 - 29,1 t/ha, or an authentic increase of a crop depending on variety from 5,3 to 10,4 t/ha. Processing of plantings of a potato by growth stimulator Ekosil promoted increase in the content of starch in tubers against fertilizers N90Р60К90 at variety Uladar to 14,4% (+2,0), Lazurit - 16,6% (+1,5), at application Gidrogumat - is maximum at variety Molli to 19,6% (+6,6). At application of growth stimulator Gidrogumat the increase in the maintenance of vitamin C at variety Uladar - 12,9 mg of% (+2,9), Kapriz - 14,3 (+1,2), Lazurit - 17,7 mg% (+2,2) is noted also, Ecosil, Kapriz and Lazurit promoted decrease in accumulation of nitrates in tubers of variety Uladar. Fertilizes rate N90P60K90 and presprouted seed tuber provides saleable early yield of 18.3 to 29.1 t/h in comparison with 11.6 to 21.2 t/ha when planted with non-presprouted tubers.
