Effect of previous crop fertilization with nitrogen and seed treatments with Co and Mo on the morphological characteristics of soybean

This three-year study examines the effect of previous crop fertilization with nitrogen and seed treatment with micronutrients cobalt and molybdenum on the morphological characteristics of soybean. Data were processed using analysis of variance by two factorial split-plot experiment with influence of year, where examination factors were: year, different doses of nitrogen fertiliser (main plot) and seed treatment (subplot). Significance of differences between treatments was tested by LSD test. Examined morphological characteristics were significantly dependent upon the year, which had a statistically significant effect. Other examined factors and interactions were not significant, except for the interaction of year x fertilization x seed treatment (AxBxC) that was statistically significant for plant height up to the first fertile node.
