The variability in the seed yields obtained in the consecutive years of the experiment
was significantly higher than that of the relative protein content in seed mass,
which meant that the protein yield was positively correlated with the yield of seeds,
depending on the changeable weather conditions. In other words, higher seed yield
well compensated for the depressed relative protein yield (Table 3).

Comparing the cultivars, it needs to be said that the highest relative decline in
yields in the third year of the experiment was recorded for cv. ‘Eurika’ and ‘Wenus’
(Fig. 3), although the increase in the relative content of protein compensated this
loss, especially in the case of cv. ‘Eurika’, whose relative protein yield in the third
year of the experiment was the highest among all the cultivars tested (Table 3).

The application of seed dressing chemicals was an experimental variable, which
was independent from weather conditions. The response of pea seed yielding to the
preparations used was clearly evident and statistically significant in years. Versus the
control plots, where no seed dressing treatments were conducted, the protein yield
obtained was much higher. Such correlation occurred irrespective of weather conditions,
in all the years of the trial and for all the cultivars. The increased seed mass
attributed to the application of the seed dressing chemicals was caused by the pro-
