Tolmachova A. Agroclimatic assessment for conditions of soybean cultivation in Ukraine

The thesis is devoted to research into the impact of agro-climatic conditions on productivity of soybean, one of the important protein and oilseeds in Ukraine. Patterns of influence of agrometeorological conditions on the photosynthetic productivity of soybeans are experimentally studied and established. Calculations of agroecological yield categories (potential yield, weather-conditioned probable yield, actually possible crop yield and the yield in production) in the context of administrative regions of Ukraine were made in terms of the soybean-modified base model of agro-climate resource assessment for the crop. A comprehensive assessment of agro-climate resources of soybean in Ukraine was made by the rate of the crop yield. Maps of spatial distribution for agroecological soybean yields and valuation ratios for agro-climate zones in Ukraine were drawn. An estimation of photosynthetic efficiency in the irrigated soybeans under the terms of the climate change is performed.
