USE OF SOIL BACTERIUM PREPARATION IN THE SPRING BARLEY PRODUCTION

Abstract

We examined the effect of fertilization and soil bacterium preparation on the yield and protein content of spring barley varieties in 2011. The experiment was set in three repetitions, random blocks. The soil of the experiment was calcareous meadow chernozem. During the experiment we applied seven different fertilizer bacteria treatments, which we supplemented with a control plot.  The year 2011 was unfavourable for spring barley production. In 2011 the amount of precipitation in the vegetation period of spring barley was lower than the average of 30 by 39.7 mm. As a result, relatively low yields formed. The control plots had the lowest average yield, 2.2-2.42 t/ha. We can claim that improving the nutrient supply the crop results were higher. Without the bacteria treatment the yields were between 3.12 and 4.42 t/ha, the protein contents were 8.94-12.41%. The most favourable yield results occurred in case of N 80 kg/ha+PK and N 120kg/ha+PK treatments. Under the influence of soil bacteria treatments the average yields were better in many cases, as well as that of the protein content, which obviously proves the nutrient transformation ability of the bacteria.
