Green manure is an essential technology for conservation agriculture models. Jack beans are an example of green manure with great potential for use, however, in addition to the low availability of quality seeds, there is a certain lack of techno-scientific content on production techniques and seed quality. Thus, the objective of this work was to determine, through a systematic review, the situation of scientific research regarding the production and quality of jack bean seeds in the world and to evaluate, based on the morphological marker 'pod color ', the ideal harvest time for this species. Furthermore, it was intended to establish a methodology for carrying out the tetrazolium test in jack bean seed. With this research it was observed that Brazil assumes a prominent position in research related to the production and quality of jack bean seeds. With regard to seed production and quality, there are three studies, linked to the web of science, related to the proposed theme, which expresses the need to develop research to promote this area. Regarding the harvest time, it was concluded that the physiological maturity point in jack bean seeds can be characterized by the presence of yellowish pods. However, due to the seed's degree of moisture, the recommended point for harvesting is possibly the intermediate point between yellow and brown pods. Under the conditions of the worked seeds, for the tetrazolium test, the ideal preconditioning and staining times are 12 hours and 4 hours, respectively.
