Growth, development and productivity of Bromus inermis depending on the elements of growing technology in non-irradiated conditions

Abstract

The article presents the results of many years of field research of the Bromus inermis productivity with different feed systems. The studies were conducted during 2011-2014 on gray forest soils. The following factors and their variants were included in the research scheme: the rate of mineral fertilizers and the time of foliar feeding with water-soluble fertilizer Master 18.18.18+3 at a dose of 5 kg/ha. Mars and Vseslav varieties were grown during the experiments. The experimental data from Bromus inermis were processed by the standard ANOVA procedure within MS Excel software. The most effective system of Bromus inermis fertilizer is the combination of mineral fertilizers N60P45K45 with the application of water-soluble fertilizer Master in the tillering stage (1-2 ten-days periods of April) and in the heading stage (1-2 ten-days periods of May) at a dose of 5 kg/ha, which, during the years of experiments in average, provided 355 kg/ha of the seeds yield of the Mars variety and 370 kg/ha of the Vseslav variety, that is 55 and 60 kg/ha more than with the use of mineral fertilizers and 225 and 245 kg/ha more than in variant without fertilizers.
