The aim of the research was to investigate the efficiency of two fertilizers accepted for organic agriculture (CODAMIX - F1 and ECOAMINOALGA - F2) on different field crops and to compare their effects on yield performances. The experimental study developed during 2019-2020 in Albota, Argeș County is based on investigation of the variability of yield components for wheat, sunflower, maize and soybean crops under influence of organic fertilizers application. The experimental scheme was composed from four plots and three variants (control, F1 and F2) for each crop. Organic fertilizers (F1, F2) were applied foliar during vegetation period as one treatment for wheat and two treatments for the other field crops. For wheat (Trivale variety), all investigated yield parameters increased after foliar fertilization, a significant increase of total biomass and spikes biomass being noticed after F2 treatment. As concerning the sunflower (Puntasol CL hybrid) and maize (F376 hybrid) crops, the results indicated significant and distinct significant differences between treatments and control variant. In the case of soybean (Florina F variety) crop, application of organic fertilizers influenced positively all yield parameters but considering drought conditions of the year the yield was generally affected.
