Abstract The article “Research on the mineral nutrition in the pear garden” by Dr of Agricultural Sciences Kopytko P.H., Candidate of Agricultural Sciences Yakovenko R.V. and graduate student Petryshyna I.P. deals with data from scientific literature on the nutrition of fruit trees of pears and apples. It is pointed out that the nutrition of pear trees is grounded and done upon the recommendations based on the research of the nutrition of apple trees. But nutrition requirements of the given crops significantly differ. Thus it is necessary to do research directly in the pear garden. That kind of research is done with Konferentsia and Osnovyanska varieties of pear trees on the dark-grey podzolized soil of Rightbank Forest-Steppe of Ukraine. Variants of optimized by nitrogen, phosphorus and potassium nutrient status compare to the complete control (without fertilization) (N90P60K90). The estimated rates of nutrients for making optimal content of available for nutrition plants N, P2O5 and K2O in the soil are significantly less than recommended by the process control. The indices of yielding capacity of young trees in the variants of optimized by nitrogen, phosphorus and potassium levels of mineral nutrition are presented. They are significantly higher than the indices in the complete control and nearly the same as the indices in the process control.
Key words pears, optimization of mineral nutrition, fertilization, yielding capacity.
