The article presents the results of research on the influence of the method of sowing and mineral fertilizers on the indicators of the structure of the yield of seed alfalfa in the Ganja-Gazakh zone of Azerbaijan. It has been established that the method of sowing and mineral fertilization has a positive effect on the indicators of the structure of the yield of seed alfalfa.
