Effect of the biological preparations azofit and amalgerol on sugar beet seeding

Abstract

In the considered years Azofit 11 ha-1, Amalgerol 41 ha1 and the mixed solutions of these biological preparations were applied on sugar beet variety 'Ernestina' at the 21-22 growth stage (BBCH scale). The findings revealed that the application of the considered preparations resulted in by 4.99-6.65 t ha-1 or by 7.26-9.67 % statistically higher yield, by 0.48-0.74 % statistically higher sugar content in the roots, and 1.03-1.21 tha-1 or 11.8-13.8 % higher white sugar yield than in the control. The application of the considered biological preparations for two times resulted in statistically reliable increase of the sugar beet yield by 6.20 - 7.14 t ha4 or by 9.02-10.39 %, by 0.53-0.79 % statistically higher sugar content in the roots, and 1.24-1.47 t ha-1 arba 14.23-16.87 % higher white sugar yield than in the control. Intensive soil cultivation, abundant application of the fertilizers and plant protection means leads to disbalanced biological processes in soil. Soil compression results in unfavourable conditions for macrobiological processes, soil consolidates, stops respiring, moisture is suppressed and due to unfavourable for growth conditions roots rot. Pest control leads to the death of the bacteria, which support good soil structure, stimulate mineralization, decay of the plant residues. Application of the biological preparations in agriculture is beneficial in several ways: activates soil microorganisms, plants grow intact, produce higher and better quality yield. In 2011-2012 the experiments on the application of the biological preparations Azofit and Amalgerol in sugar beet seeding on the Calc(ar)i-Epihypogleyic Luvisol IDg8-k (LVg-w-cc) soil of the experiment station of ASU were carried out. Alive Acotobacter vinelandii bacteria form the basis of Azofit preparation. They fix nitrogen, and biologically active matter. They assimilate nitrogen from the atmosphere and release it into soil in the available for the plants form. The application of this preparation solution results in better mineral matter uptake, more intensive growth and higher yields. Amalgerol - liquid biological preparation, acting as biological stimulant and is applied to stimulate soil microorganisms and physiological functions of the plants. Preparation Amalgerol consists of more than 40 components - vegetative and essential oils, oil distillates, herb extracts. Application of this preparation results in activation of the soil bacteria, more active decomposition of the yield remains, enrichment of the easily assimilated nutrient matter. This product not only has positive effect on microorganisms, stimulates the development of the plant roots and above-ground part but also plant development in general.
