The effect of fertilization and effective microorganisms on buckwheat and millet

Abstract

The experiment was conducted in 2016 and 2017 in the vegetation hall of the Faculty of Environmental and Agricultural Development, West Pomeranian University of Technology in Szczecin. The main goal of the study was to assess the influence of the biological preparation of effective microorganisms (EM), mineral and natural fertilization on: the yield of buckwheat ( Fagopyrum Mill.) and millet ( Panicum miliaceum L.), the SPAD index (leaf greenness index), the content of macro- and microelements in grain (N, P, K, Ca, Mg, Na, Cu, Mn, Mo, Fe and Zn), pHKCl, the content of organic C (Corg), macro- and microelements (N, P, K, Ca, Mg, Cu, Mn, Fe and Zn) in soil. Both of the species studied responded with a significantly higher yield due to natural fertilization. The positive role of the EM used should be emphasized, especially in relation to the soil. In buckwheat and millet plots, in which EM were applied, there was an upward trend in the concentration of the investigated macronutrients in the soil. The experiment conducted shows that microbiological preparations can improve the chemical properties of the soil, and the nature of their activity may depend on their type, dose, the species of the plant, the stage of development during which it is applied, and the climate and soil conditions.
