In the conditions of the Republic of Belarus there were presented data on agroeconomic efficiency of a growth regulator Emistim C depending on different rates and terms of foliar extra-nutrition of cereals and tilled crops at cultivation on sod-podzolic soils are presented. Studies to evaluate the effectiveness of agro-economic growth regulator Emistim C were carried out in four field experiments on sod-podzolic soils. The experiments with potato (Solanum tuberosum) of Skarb variety and maize (Zea mays) of Delfin variety grown for grain were laid on sod-podzolic sandy loam soil, experiments with wheat (Triticum aestivum) of Toma variety and barley (Hordeum vulgare) of Batska variety - on sod-podzolic soil. Foliar treatment of potato crops with the growth regulator Emistim C had the largest agro-economic effects at the bud stage in a dose of 20 ml / ha. When corn cultivation on sod-podzolic sandy loam soil foliar fertilizing with the growth regulator Emistim C at a dose of 20 ml / ha in the phase of 6-8 leaves of plants provided grain growth compared to the background by 21.5 kg / ha, with the growth regulator Ecosil (standard) - by 14.9 kg / ha. Foliar treatment of spring wheat with the growth regulator Emistim C had the largest agro-economic effects at a dose of 20 ml / ha in the flag leaf stage. Foliar fertilizing with growth regulator Emistim C at a dose of 20 ml / ha of barley in the flag leaf stage provided the increase of grain by 5.4 t / ha compared to the background.
