EFFECT OF FERTILIZER SOURCE ON THE NUTRIENTS BIOLOGICAL UPTAKE WITH GARDEN BEANS PRODUCTION

I. Mitova, I. Stancheva

Abstract: Garden bean pants (Phaseolus vulgaris (L.) Savi.) ssp. Nanus cv. Xera were grown under glasshouse conditions at optimal fertilizer rates using mineral, organic and foliar fertilizers previously established in a model pot experiments. The favorable effect of the foliar feeding on the yields of garden bean pods was shown. Total amounts of the biological uptake of nutrients with the vegetative biomass and pods production were observed to be maximal both in the organic and foliar fertilized plants. The percentage of nitrogen, phosphorus and potassium uptake in the plants with mineral and organic fertilization was equal. In foliar fed plants percentage of P and K increased in comparison in the other treatments on the account of nitrogen level. The amounts of nutrients required for the formation of obtained yield were determined on the base of its biological uptake.
