statistically using analysis of variance for multiple trials, testing the hypotheses according
to T-student test at α = 0.05.
While discussing the effect of the seed dressing chemicals applied and the weather
conditions on the content of total protein in pea seeds, it is necessary to state a
priori that weather conditions prevailing during the three years of the experiment
were variable. Two basic factors, in particular, were highly changeable – air temperature
and rainfall (Fig. 1 and 2).

The first year of the tests (2004) was warm, with mean monthly precipitation
suitable for the growth and development of pea plants. The second year (2005) was
warmer, with the mean monthly temperature higher than long-term means and with
lack of rains in April and July. Regardless of those differences, both years can be
considered favourable for pea cultivation.
The last year of the trial (2006) was completely different. Early spring was
rather cold, whereas June and July were extremely hot with very little and sporadically
occurring rainfall. It should be stressed that July in 2006 was the hottest month
in this part of Poland during the past 200 years – the average temperature reached
more than 23.5°C.
