Abstract :Leguminous plants fix nitrogen in the air by forming nodules. Phosphorus fertilizer, on the other hand, contributes to plant growth and grain yield together with nitrogen. For this purpose, four phosphorus (0, 3, 6, 9 kg da-1) and four nitrogen (0, 4, 8, 12 kg da-1) doses were applied to the Göksun bean variety, and the most appropriate dose for plant growth and grain yield was tried to be determined. In the study, the oil rate (%), ash rate (%), moisture rate (%), fiber rate (%), protein rate (%), starch rate (%) and thousand grain weight (g) values of Göksun bean cultivar were investigated. The study found that nitrogen fertilization significantly affected starch content and thousand-seed weight, two of the most important grain quality criteria for beans. The highest thousand-grain weight was obtained with the 12 kg da-1 nitrogen dose and the combination of 12 kg da-1 nitrogen and 6 kg da-1 phosphorus doses.
