Abstract

Over 2003-2005 at the Experiment Station at Wierzchucinek at the University of Technology and Life Sciences in Bydgoszcz, there was performed a strict one-factor micro-plot experiment in split-splot design. The factor tested was a type of microelements [n=5: Cu, Zn, Mn, Mo, B]. The microelements were foliar sprayed in a chelated form, as the series of ‘Symfonia’ fertilizers. The study aimed at comparing the effect of five agricultural-engineering basic microelements on the contents and protein composition of the seeds of ‘Aura’ cultivar. The fertilization applied, boron and manganese in particular, showed an effect on the increase in the contents of total protein in bean seeds. It also modified the fractional composition of the bean seed protein. There was observed a clear increase in the fraction of albumins and globulins in seeds as a result of the microelements applied, except for boron. The fertilization with molybdenum, boron, copper and zinc reduced the content of glutelins, and the sum of glulelins and prolamines in the bean seeds.
