The increase in crop capacity and quality of produce is achieved by leaf-feeding of oil flax which provides a good development of plants and the richest yield.
The purpose of the study. Taking into consideration all above mentioned, the aim of the research was to determine the influence of leaf-feeding against mineral fertilizing (N 60P 30K 60) on the crop capacity and the quality of oil flax seed in the conditions of the Western Forest Steppe.
Research Methods. We used the general scientific and special methods. The main method of research was the field method, which was complemented by standard analysis in agriculture, crop production, economics and statistics methods.
The results of research. Leaf-feeding against the background (N60P30K60) in all the variants provides the increase in crop capacity from 2,79 up to 3,11 t/ha, the increase before control 1,36 – 1,68 t/ha correspondingly, before the background 0,12-0,44 t/ha.
The richest crop capacity of oil flax seeds – 3,11 t/hа in average for the period of 2012-2013 – was obtained with the application of complete mineral fertilizer N60P30K60 combined with leaf-feeding with carbamide, magnesium sulfate 5% content and the fertilizer of complex action oil nutrivant plus 2 kg/hа-twice (the first time – at the “fir-tree” stage, the second one – at the beginning of budding stage). The increase before control (without fertilizers) was 1,68 t/hа, before the background – 0,44 t/hа.
Conclusions. Was ascertained that the highest oil flax crop 3,11 t/ha capacity was provided by leaf-feeding with carbamide, magnesium sulfate 5% and oil nutrivant plus applied twice (at the “fir-tree” and budding stages).
