Abstract

The purpose. To determine economic efficiency of application of liquid phosphate fertilizers under potato at growing on dark grey podzolized soil in Left-bank Forest-steppe. Methods. Field, statistical. Regular disposition of alternatives. Results. It is established that application of liquid phosphate fertilizers in standard dose of P35 has positive economic benefit: conditional-net profit makes 18,2 thousand hrn/hectare. At augmentation of doses of these fertilizings up to P70 expenditures for growing have increased, but income was high — 30,1 thousand hrn/hectare. Addition in fertilizer system of fertilizers with Ca, Mg and B promoted augmentation of manufacturing costs on 1550–1770 hrn/hectare, but because of smaller productivity the level of profitableness in these alternatives has decreased on 18,2–26,3% in comparison to alternatives in which applied fertilizers only with NPK. The highest economic indicators characterized alternatives with importation of liquid combined fertilizers of brand 11- 37 in dose of P105 and foliar top dressing Atonikom Plus (0,20% solution) where conditional-net profit made 70 thousand hrn/hectare, and level of profitableness — 75,1%. Conclusions. By the probes it is established that application of LCF 11-37 with foliar top dressing Atonikom Plus is economically justified and is of great importance for practical application. Affirming to that — high economic indicators in alternative with importation of liquid combined fertilizers of brand 11-37 in dose of P105 and foliar top dressing Atonikom Plus (0,20% solution) where conditional-net profit attained peak figure (70 thousand hrn/hectare), and level of profitableness — 75,1%.
