The influence of sustainable fertilization on the parameter of soil biogenicity, weight of 1000 grains and the yield of different maize genotypes

Abstract

One of the world's biggest problems in the last few decades is the production of food while protecting the land and resources necessary for survival. Land is one of the most important resources for humanity, so it is very important to protect it from degradation. Due to the lack of sufficient quantities of organic fertilizer, it is necessary to find an alternative that will meet the principles of sustainable production. The goal of the work was to determine the impact of the application of a microbiological preparation with effective microorganisms in a sustainable corn fertilization system. The experiment was set up as a two-factorial: Factor A fertilization (160 kg ha-1 -control and 120 kg ha-1 + microbiological preparation with effective microorganisms. The preparation was applied to the soil 30 l ha-1 before sowing and during the growing season in phases 15 BBCH and 19 BBCH per 6 lha-1 . Factor B of three maize hybrids ZP 427, ZP 548 and ZP 684. At the end of the growing season, samples were taken for the analysis of the total number of bacteria, azotobacteria, fungi and actinomycetes. After the harvest, the weight of 1000 grains and the yield of grains were determined. was also lower in the abundance of azotobacter, which was not determined even in the control variant, due to inadequate soil properties. Mass of 1000 grains and yield also had higher values than in the control, but without statistically significant difference. In the end, it can be concluded that by applying preparations with effective microorganisms with a smaller amount of mineral nitrogen by 40 kg ha-1 , economically justified yields and the possibility of reducing soil degradation can be achieved.
