Effect of organomineral fertilizer Viteri 8-4-5 on the growth processes of crop plants at the early stages of ontogenesis

Abstract

Under conditions of laboratory experiment, the optimal concentrations of organomineral fertilizers Viteri 8-4-5 were selected and their influence on plant growth processes of crops at the early stages of ontogenesis by morphometric indices was shown. The growth processes of 9-day seedlings of the soybean of Cordoba variety as well as the spring wheat of the Tryzo variety, oats of Desnyansky variety, the hybrid of maize DN Vys’, and the buckwheat of Ukrainka variety, grown under water culture conditions were investigated. The dilution range of the organomineral fertilizer was from 10–1 to 10–8. Plants grown on distilled water were a control variant. The optimum concentration of the investigated preparation for influence on growth processes of seedlings of soybean and spring wheat has been revealed. For the application of organo-mineral fertilizers in concentration 10–2, the length of the above-ground part of the seedlings of soybean of the Cordoba variety and spring wheat of Tryzo variety, as compared with control, increased by 29.8% and 18.4% respectively. Positive effect of the fertilizer both on the length and on the mass of the above-ground part of the seedlings of the oats of Desniansky variety was shown on the variant with the dilution of the preparation 10–1. Thus, for the effect of the preparation in this dilution, the length of the above-ground part of the seedling was 15.73 cm, and the mass was 0.080 g, which exceeded control by 15.4 and 21.2% respectively. These studies point to the prospect of further study of the effects of the application of organo-mineral fertilizer VITERI 8-4-5 on the growth processes of crops at the early stages of ontogenesis and the possibility of its use for both pre-seed treatment of seeds and for its application on sowings of agricultural crops during vegetation to optimize their technology of cultivation, including organic farming.
