Results. The results of the experiments show clearly what effect weather conditions
produced on the yield of protein obtained from each pea cultivar tested. Let
us not forget that the volume of protein yields was a product of two traits, i.e. seed
yield volume and per cent concentration of protein in seeds, both under the direct
influence of weather conditions, rather than an intrinsic characteristic. Those two
traits significantly varied between the years of the trial, showing a diverse direction
of modification. On the one hand, the mean seed yield volume for all the four pea
cultivars was higher in the first two years (4.38 and 4.32 dt/ha, respectively), decreasing
considerably in the third year (down to 3.11 dt/ha). On the other hand, the
relative protein content in pea seeds was the highest in the last year of the trial
(25.3%), which was considerably higher than in the first two years (20.9 and 23.9%,
respectively) (Tables 1 and 2). This means that the less favourable weather inhibited
synthesis of non-protein compounds in pea seeds to a slightly larger extent than that
of protein.
