During the two-year study on the influence of presowing fertilization on growth and development of garden pea (Pisum sativum L.) in three different experimental setups, five genotypes of peas were used, two of Dutch origin and three that were created at the Institute of Field and Vegetable Crops.The aim of the study was to determine the extent to which different genotypes and complex NPK fertilizer influence the yield per plant. The average yield per plant for both years was 16.86 g. The influence of genotype on grain yield per plant was statistically significant (p is less than 0.01). Tamish cultivar showed significantly lower yields during both study years, in comparison with other genotypes tested, except when compared with the Danube cultivar in year 2007. There was no regularity in the influence of pre-sowing fertilization on grain yield per plant. Regression analysis of the pea genotypes, revealed a slight reduction in yield per plant as a function of increased use of complex fertilizer. Grain yield per plant was in high positive correlation (p is less than 0.01) with yield components, and with the length of the stem. The number of pods was in strong correlation with grain numbers and weight of pods. Number of grains and the absolute weight were in highly statistically significant correlation with the mass of pods.
