A three-year study examined the effects of increasing fertilizer N rates (0, 20, 40, 60 N kg ha-1 and
equal P and K rates) and utilization stage on the yield and quality of pea (Pisum sativum L. Cv Junior)
fodder and grain, with the aim of determining optimal N fertilizer rates and the most favourable stage
for exploitation. The highest dry matter yield at the stage of flowering and at the milk-waxy maturity
stage was obtained in the first study year in the treatment receiving 60 kg ha-1 N. This was a result of
optimal temperatures and adequate moisture supply during the period of vegetative growth. However,
the grain yield was highest in the 40 kg N ha-1 treatment, having been caused by the vegetative growth
stimulation and crop lodging at the end of the developmental cycle. The crude protein yield varied in
accordance with the dry matter yields
