  The calculated equation of the Penman-Monteith method for determining evapotranspiration (ETc) is derived from the equation of energy balance of the soil surface, and the dependence of ETc on ETo reflects the culture coefficient Kc. Since the values of Kc (FAO) are typical values for standard climatic conditions, which are defined as sub-humid climate, it is necessary to evaluate this model for the conditions of the Steppe of Ukraine, whose climate is drier. Thus, the aim of scientific research was the adaptation of the calculation method for determining the evapotranspiration of the ETc "Penman-Monteith" to the irrigated conditions of the Steppe of Ukraine on the soybean crop. The work involved conduction of short-term field experiments, generally accepted analytical research methods; the use of methods of variance, correl.. Read More»
