SUMMARY:

The study investigated the productivity of two agronomic species, Carthamus tinctorius (safflower) and Zea mays L. (maize), in soils treated with biochar and eucalyptus pyroligneous extract. Conducted in two phases, the research included field analysis in Mossoro and the results obtained in Macaiba, Rio Grande do Norte. The tested doses of biochar were 0, 3, 6, and 9 t/ha, applied either alone or in combination with the wood vinegar. The results for safflower showed that the application of 3 t/ha of biochar had a positive effect on the number of plants and height, while higher doses inhibited capitulum production and decreased fresh mass. The oil content of the seeds was maximized with the dose of 6 t/ha of biochar. In relation to maize, the combined use of biochar and wood vinegar resulted in a significant increase in productivity, with the dose of 6 t/ha of biochar presenting the best performance in terms of grain yield. However, the higher dose of 9 t/ha resulted in lower production, highlighting the importance of optimizing dosages. Thus, the study concluded that both biochar and wood vinegar have the potential to improve crop productivity, contributing to sustainable agricultural practices. Appropriate doses of biochar are essential to maximize benefits, making it a promising resource for small producers seeking viable and low-cost alternatives.
