Kuts O. Influence of microelements on productivity and quality of late white cabbage and red beet on the typical chernozem of the left bank Forest-steppe of Ukraine.

Object: Regularities of forming the yield high level of white cabbage and red beet, improvement of their quality owing to optimization of mineral nutrition. Aim: to substantiate scientifically the necessity of microelements usage against the background of application of macrofertilizers optimal doses when growing late white cabbage and red beet on the typical chernozem in the Left Bank Forest-Steppe of Ukraine. Methods: visual, measuring-weighing, laboratory, mathematical-statistical, calculative. Novelty: for conditions of the Left Bank Forest-Steppe of Ukraine there is worked out the scientifically substantiated decision as for microelements application under late white cabbage and red beet; determined optimal parameters of microfertilizers usage under these kinds of plants, their influence on the yield and the quality of the produce; ascertained carrying-out of main microelements by these vegetable plants with different levels of providing with macro- and microfertilizers; calculated bioenergetic rating and conducted economic analysis of microelements application when growing white cabbage and red beet. Results: there have been worked out main elements of microfertilizers application when growing late white cabbage and red beet, which allow to obtain the output of marketable produce at the level 49-54 t/ha of cabbage and 35-42 t/ha of red beet; with this the estimated profit is Hr. 16-32 ths, the profitableness of production is 109-135%; the coefficient of bioenergetic efficiency is the highest - 3.5 for cabbage and 6.5 for red beet. Introduction extent: introduced in agricultural enterprices of different forms of property in Kharkiv rg. Field of use: vegetable growing.
