The purpose of this study was the analysis of the organic foliar fertilization influence on the groundnut yield. The experience was located at SD Banu Mărăcine, Tâmburești farm, on sandy soil, in 2015-2017. The experiment included two factors. The graduations of A factor (A1 and A2) were consider fertilization type. First graduation A1 - normal fertilization of soil with NPK complex fertilizers (20:20:0), 200 kg/ha and the second graduation A2 - same fertilization of soil and three extra leaf fertilization with Humusoil, 2 l/ha. B factor (genotype) had 6 graduations (genotypes). The analyzed characters were: pods yield, efficiency, total number of pods/plant, percent of total mature pods/plant, weight of 1000 pods/plant and weight of 1000 seeds/plant. Fertilization and genotype and their interaction statistically influenced all characters, except percent of total mature pods/plant. In the case of analysis of the interaction of the two factors, concerning the pods yield, the best results are obtained from the genotypes Solar and Venus at the A2 graduation (2884.24 kg/ha pods yield respective 2895.45 kg/ha pods yield), by additional foliar fertilization the genotypes registering superior results compared with the basic fertilization.
