The efficiency of using bioсlimatic resources by spring barley and sunflower in Donbass

The aim the research was to evaluate the use of biocli- matic resources of different areas of Donbass Region by spring barley and sunflower crops in the conditions of warm- ing of the climate. The research objective was to study and calculate bioclimatic resources indicators of all areas of Donbass Region, to develop the method of efficiency evalua- tion of agroclimatic resources use when growing spring barley and sunflower. The objects of the research were modern indicators of all areas of Donbass Region, average annual regional yielding capacity of these crops. To carry out the research the method of D.I. Shashko and Yu.A. Gulyanov was used. The information from agroclimatic manuals of Donbass, average regional yielding capacity of spring barley and sunflower according to statistical office records for thelast 20 years was used. Bioclimatic potential BCP per unit, biological climate productivity BCP in points, growth coeffi- cient GC, humidity coefficient HC according to D...
