SUMMARY:

This study investigated the cultivation and seed production of five species from the Fabaceae family used for soil cover and green manure under semi-arid conditions in the region of Morro Vermelho, Municipality of Montes Claros, MG, Brazil. The experiments were conducted between November 2022 and June 2023. A randomized block design was used in this trial, with the cultivation of five species:  mucuna-cinza, sunn hemp (juncea), sunn hemp (ochroleuca), sunn hemp (spectabilis) and jack bean. Seedling emergence, days to flowering, maturation, seed yield, germination and vigor were evaluated. The results were discussed and registered regarding the percentage of seedling emergence, days after sowing to flowering, and differences in productivity, germination, and vigor when cultivated under the same environmental and management conditions. In a second experiment, seed samples of sunn hemp spectabilis, which exhibited seed coat dormancy, were subjected to different treatments to overcome this dormancy. The experiment was conducted in a completely randomized design with five treatments and four replications. Seed soaking for 23 hours reduced the percentage of hard seeds and promoted the highest germination percentage. This work contributed to evaluating seed production under semi-arid conditions and provided relevant information for the proper management of the cultivation of the studied species, with an emphasis on producing seeds in both quantity and quality.
