Biological Substantiation of Application of Microfertilizers and Organo-Mineral Preparations for the Foliar Treatment of Wheat

详细

Data on the evaluation of the effect of ten preparations based on humic substances and silver (FlorHumat, Flora-S, Edagum, Fitop Flora-S, Zerebra agro, BatyrMax, Batyr 40N, Batyr 40N + Max, Azofoska) on the productivity of spring soft wheat are presented. Plant productivity was studied according to the following parameters: plant phase (according to the Eucarpia scale), the number of germinal and coleoptile roots, the length of germinal and coleoptile roots, the number and length of nodal roots, the total mass of roots, the mass of the vegetative part of plants, the length of the 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 plants, the area of the flag leaf and preflag leaf, productive tilling capacity, and general tilling capacity. The foliar treatment of plants with the preparations was carried out in appropriate concentrations in the evening during the phases of wheat tillering and flag leaf formation. The biological yield of the wheat was most strongly influenced by the BatyrMax preparation. The Edagum preparation showed maximum efficiency in the number of significant positive changes in wheat productivity compared to the control (untreated plants) and background (the plants were treated with the Azofoska preparation). The similarities in the action of Edagum, Fitop Flora-S and Zerebra agro, and Batyr 40N + Max preparations on the changes in most of the wheat productivity indicators were revealed. There was no statistically significant effect of Flora-S, FlorHumat, and Azofoska on the yield.
