Among all cultivated lupine species, yellow lupine features the most significantly contribute to the improvement of soil fertility in Poland high economic value of this species results from the fact that this plant is especially rich in protein as well as to, its usefulness for cultivation on light soils. The aim of the research was to assess the effect of seed vaccination with Nitragin and chemical protection against anthracnose on the development and yielding of two cultivars – Mister and Taper, field experiment was conducted in 2006–2007 in Dzikowice, Lubuskie province, according to split-plot method with three variables: 1. cultivars (Mister, Taper), 2. seed vaccination (with nitragin, without nitragin), 3. chemical protection against anthracnose. The experiment proved that seed vaccination with nitragin positively affected the size and number of root nodules, germinating power, number of pods, number of seeds in a pod, length of plant growing period, protein and fiber content in lupine seeds. Vaccination, however, disadvantageously affected such parameters as plant height and fat content. The latter treatment did not significantly influence thousand seed weight. As the years of investigation did not favor anthracnose occurrence, there were not observed any considerable differences between the treatments. The cultivars under examination, because of different morphotypes of yellow lupine, varied in the rate of plant growth, length of plant growing period, plants cut, as well as seeds chemical composition.
