One of the solutions to environmental problems related to the use of chemical inputs in agricultural production is the use of crop residues, animal manure, organic and biological fertilizers instead of using foreign inputs. The aim of this study was to evaluate the effect of biological and chemical fertilizers of nitrogen and phosphorus on the quantitative and qualitative yield of sunflower. The experiment was performed as a split factorial in the form of a randomized complete block design with 3 replications in the summer of 2011.
