Garden bean plants (Phaseolus vulgaris (L.) Savi.) cv. Xera were grown under glasshouse conditions at optimal fertilizer rates using mineral, organic, and foliar fertilizers previously established in a model pot experiment. It was shown the favorable effect of the foliar feeding on the biomass accumulation in the different vegetative organs and formation of fresh products with low levels of nitrates and nitrites. In the leaves of the plants with foliar feeding higher levels of nitrate reductase enzyme activity are observed which contributes to more intensive nitrogen uptake. No differences are established among the variants with different fertilizer sources regarding plastid pigment content.
