In the conditions of the Republic of Belarus there was studied the influence of plant growth regulator Ehkosil, complex liquid fertilizers Basfoliar 36 and Vitamar, combined application of Basfoliar 36 Extra with plant growth regulator Ehkosil on potato crop yield and quality. There was evaluated economic efficiency of macro- and micro fertilizers and plant growth regulator Ehkosil application for potato (Solanum tuberosum) cultivation. The field experiment was realized in 2008 – 2010 on sod-podzolic soil. The complex liquid fertilizers Basfoliar 36 contained nitrogen and microelements (36.3% - N, 4.3% -MgO, 1.34% - Mn, 0.27% - Cu, 0.03% - Fe, 0.03% -B, 0.013% -Zn, 0.01% - Mo). The complex preparation Vitamar contained microelements and growth regulator (MgSO4 7H2O – 220 g, H3BO3 -20 g, ZnSO4 7H2O – 20 g, MnSO4 4H2O – 120 g, CuSO4 5 H2O – 260 g, (NH4)6Mo7O24 20 – 10 g, Fe SO4 7 H2O – 120 g, ferrous ammonium sulfate (NH4)2SO4 FeSO4 6H2O – 10 g, humates – 50 ml on 1 l of solution. It was found that application of growth regulator Ekosil, complex fertilizers Basfoliar 36 Extra and Vitamar for growing of potatoes on sod-podzolic soil, in comparison with the background of N100P60K130 increased tuber yield on 10.6 c/ha, 24.8 and 21.3 c/ha, and output of starch – on 3.5 c/ha, 6.5 and 9.6 c/ha.
