Ilyinsky Y. The influence of basic cultivation and fertilization on derno-podzolic and loamy sand soil fertility and hop productivity under the conditions of Polissya

The object of research is a process of change of main fertility indexes of derno-podzolic soil and productivity of hop depending on agrarian and technological approaches of growth. Purpose is to determine the effect of long-term systematic application of various compounds of technology of growing hop on the productivity of derno-podzolic clay soil, productivity of planting hop and efficiency of its growth in Polissia region. Methods of research are field, laboratory, measuring, comparative, and mathematically statistical. It was the first time that it was determined of influence of subsurface main tillage of rows and green manure management with blue lupine on aqua-physical, physical, chemical, and agrarian chemical peculiarities of derno-podzolic clay soil, yield and quality of hop cone. Improved technology of growing hop, that set the change of plowing rows and blue lupine that ensures simplification of technological process, creates advantageous conditions for preservation, and improve of main indexes of fertility of hop plants (2.1-2.8 t/ha of cones) and economy of energy resources. Scientific developments of the author were improved in years 2007-2010 in Private Company "Shchedryi Vrowzhai", Brody district, Lviv region on the field of 12.7 ha and Agricultural LLC "Polissia", Chervonoarmiisk district, Zhytomyr region on the field of 8.7 ha. Sphere of application - agricultural production.
