Biological substantiation of applications microfertilizers and organo-mineral preparations for out-root treatment wheat

The paper presents data on the evaluation of the effect of ten preparations based on humic substances and silver (FlorhGumat, FloraS, Edagum, Fitop Flora-S, Zerebra agro, BatyrMax, Batyr 40N, Batyr 40N + MAX, Azofoska) on the productivity of spring soft wheat. The productivity of wheat was studied in indicators of: the phase of the plant (according to the scale of Eucarpia) the number of germinal, coleoptile roots, the length of the germinal, coleoptile roots, the number of nodal roots, the length of nodal roots, the summary mass of the roots, the mass of the vegetative part of the plants, the length of the wheat spike, the number of spikelets in the wheat spike, the number of grains in the wheat spike, the mass of the spike, the height of the plants, the area of the flag leaf, the area of the pre-flags leaf, productive tilling capacity, general tilling capacity. Out-root treatment of plants with preparations in appropriate concentrations was carried out in the evening hours during the phases of wheat tillering and the formation of a flags leaf. The greatest influence on the productivity of wheat was provided by the preparation BatyrMax. The preparation Edagum showed maximum effectiveness in the number of reliable positive changes in the productivity of wheat compared to the control (untreated plants) and background (the plants were treated with the preparation Azofoska). Similarities in the action of Edagum, Phytop Flora-S and Zerebra Agro, Batyr 40N + Max on the changes in the most of the wheat productivity indicators were revealed. There was no statistically significant effect on the yield of Flora-S, FlorHumat, Azofoska.
