Mung beans (Vigna radiata L.) are of Asian origin and have gained national importance with the production of moyashi. The study aimed to evaluate the seed physiological quality of mung beans according to the row spacing and number of plants per meter. The experiment was conducted at Goiás State University, Ipameri Campus. Tests were performed to determine the water content, germination, and vigor to evaluate the physiological quality of the seeds. The experimental design was completely randomized, with the treatments arranged in a 2 x 6 factorial scheme, having as factors the row spacing (25 and 50 cm) and the number of plants per meter (4, 8, 12, 16, 20, and 24 plants) with four replications. Based on the results of the analysis of variance, germination, first germination count, and emergence speed index were not influenced by row spacing and number of plants per meter. The shoot length of seedlings was significative affected by row spacing and the number of plants per meter. For root length, seedling dry mass and thousand-seed weight there was significant interaction between the studied factors. There was significant effect of row spacing on accelerated aging and seedling emergence. The mung bean plant density affected seed quality. Seeds produced with a row spacing of 50 cm with 24 plants per meter had the best physiological potential.
