SUMMARY:

Coriander (Coriandrum sativum L) is a short-cycle aromatic plant widely cultivated and highly valued in Brazilian cuisine. It is predominantly grown by urban and peri-urban family farming in the metropolitan regions of major capitals. In addition to being a source of nutrients, it is utilized in the pharmaceutical industry and in phytotherapeutic treatments. Given the increasing demand from consumers for the production of vegetables without the use of pesticides, the adoption of alternative techniques for vegetable production has become essential. Consequently, modern agricultural production faces challenges such as pests, diseases, and the need to accelerate the production cycle. In this context, the use of products that promote plant growth, enhance resistance, optimize nutrition, and support sustainable production is of critical importance. Thus, the objective of this study was to evaluate the growth of coriander plants, cv. Taboca, bio-stimulated by native Amazonian fungi, Trichoderma asperellum, Metarhizium anisopliae, and Beauveria bassiana, in combination with 50% organic fertilization. The hypothesis is that the association of these fungi with a 50% reduction in fertilizer will promote faster and more efficient growth of coriander plants. The study was conducted in a peri-urban family farming commercial area in the municipality of Marituba, Pará, using a randomized block design (RBD) with six treatments: T0 – 100% organic fertilization (Control Treatment); T1 – 50% organic fertilization; T2 – 50% organic fertilization + T. asperellum; T3 – 50% organic fertilization + M. anisopliae; T4 – 50% organic fertilization + B. bassiana; and T5 – 50% organic fertilization + Mix (B. bassiana + M. anisopliae). The organic fertilizer used was poultry litter. Data were subjected to analysis of variance (ANOVA), and means were compared using Duncan's test. All fungal treatments promoted plant growth; however, treatment T4, with B. bassiana, yielded the best results for the evaluated parameters. Furthermore, the use of growth-promoting microorganisms resulted in higher profit margins, according to the economic analysis. It is concluded that the application of fungi combined with 50% organic fertilization can be adopted as a strategy for cultivating coriander cv. Taboca, as it not only promotes faster plant growth, reducing the production cycle, but also produces healthier food without contaminating the environment, the producer, or the consumer.
