Ulich O. Winter wheat variety productivity depending on terms sowing terms in the right-bank Forest-Steppe zone

Subject of research - the winter wheat kernel yield and quality formation process. Aim - the increase in wheat kernel productivity and the improvement of its quality on the basis of variety, fore-crop and sowing term selection. Methods - field, laboratory, statistical, comparative computational. Value and novelty of research - details of plant growth and development, drought, lodging, grain shattering resistance and that, to harmful organisms, the kernel yield and quality of winter wheat varieties of various groups of intensity depending on the agroecological conditions, forecrops and wing terms are revealed. It is established that in the southern part of the right-bank Forest-Steppe it is advisable to plase on bare fallow the Odeska 162 and Nikonia varieties, after sain-foin and vetch-oat mixture - the Selyanka and Yatran 60 varieties, after silage maize - the Donetska 48 variety. It is advisable to begin their sowing after silage maize on the tenth of September with the continuance after vetch-oat mixture, sain-foin and on bare fallow up to the 25th of September. Introduction - the improved varietal winter wheat growing technology was introdused during 1999-2003 at the farms of the Kirovohrad region over an area about 80 thou. ha. Field of application - agriculture.
