Summary. Within 2 years (2010-2011). Conducted studies to test a new drug - organo- mineral supplements Turmaks at potato cultivation varieties Nevsky under the Tomsk region. For this small plot field experiments were laid on gray forest soil with humus content of 4.46 %. Dining experience includes control, single and double drug spraying the plants sprouting and budding, as well as soaking seeds before planting and a further single or double spraying. The results showed that a single spraying vegetative plant parts Turmaksom on shoots and twice on shoots and budding significantly influenced the increase in the total leaf area of plants (at 231-732 cm2 compared to the control), dry weight of plants (in 3,06-5,69 g) , length of shoots (9,47-14,75 cm) and number of leaves per stem (11,5-14,7 pcs.) at the same time in a single spraying budding and preplant treatment of tubers Turmaksom showed no significant effect to accelerate the growth of the vegetative mass. Revealed that foliar treatment Turmaksom enhances photosynthetic activity of vegetative organs is reflected in an increase of chlorophyll a concentration (in g/cm2 7,74-12,58) and b (at 1,74-3,39 g/cm2) and to increase the index of PEF in a single embodiment for spraying seedlings (0.78 g m2/day) compared with the control. Significant increase in crop potatoes were obtained by spraying potato plants on shoots (9,9-10,7 %) and twice - on shoots and budding (41,2-43,5 %) and study drug treatment of tubers before planting had no significant impact on the increase in yield.
