Study of the effect of foliar dressing on horseradish yield in the conditions of the North-Western part of Russia in Pskov region

The article presents an analysis of the problems in growing horseradish in the Russian Federation which are associated with an insufficient amount of planting material, as well as with the lack of cultivation technologies and not fully studied biological features of this crop. The results of the study contain material on the study of the effect of foliar dressing with Basfoliar complex mineral fertilizer in concentrations of 1.5 and 2.5 ml/l, 2.5 and 3.5 ml/l and 3.5 and 4.5 ml/l on horseradish yield in Pskov region. The experiments were conducted in the State Agricultural Academy of Velikie Luki and at the experimental plot in Pskov region, Pustoshkinskiy district in Orekhovo village. The paper presents data on improving the technology of growing horseradish of the Uvarovsky variety. The optimal concentrations of the applied Basfoliar fertilizer on the morphological parameters of the Uvarovsky variety in concentrations of 2.5 and 3.5 ml/l were established, thus, the maximum length of the leaf blade was 60.6 cm, the length of the rhizome — 37.8 cm. The highest commercial yield — 14.5 mt/ha and annual rhizomes — 10.0 mt/ha was obtained using Basfoliar 2.5 and 3.5 ml/l. To obtain a consistently high horseradish yield, it is necessary to provide plants with a balanced mineral nutrition throughout the vegetation period. Therefore, it is necessary to study in detail when choosing specific drugs and their effect on both morphological parameters and the structure of the crop. The results obtained during this work can be used for cultivation in order to increase the crop productivity in all horseradish farms.
