In the current scenario regarding the quality of human food, alternatives for the production of food in a more sustainable way arise and require studies to be improved and applied by producers. In view of this, this study seeks to evaluate the production of vegetables in an organic system under Direct Planting using different soil coverings. Organic agriculture aims to maintain the health of ecosystems, soil and people by not using aggressive methods, using more sustainable agricultural practices, which have less impact on health and the environment, always anchored in the three principles: to be economically viable , socially just and environmentally correct. In addition, it aims to benefit the environment with the support of science and innovation, balancing the resources offered by nature and human needs, considering the soil as a primordial source of life. The search for healthy food favored the expansion of the commercialization of organic products and stimulated the organization of production cooperatives, establishments in the food sector dedicated to this purpose, boosting the economy. Although organic foods still represent a small portion of the total food trade, it should be noted that the market remains promising and constantly growing. Linked to a more sustainable agriculture is the Direct Planting System, which is a relevant tool for obtaining more sustainable production systems, also in the production of vegetables, following the principles of turning the soil in a localized way and diversifying the species by crop rotation, including cover crops and permanent ground cover. The benefits associated with the Direct Planting System for vegetables are many, including the reduction in soil loss due to flooding, water savings in irrigated crops, reduced mechanization, thermal regulation provided by straw and increased levels of matter. organic. Furthermore, a reduction in the need for fertilization can be observed, due to the preservation or recovery of soil quality.
