RESUMO:

The cultivation of melon (Cucumis melo L.) is extremely important for the Brazilian economy. The country is the thirteenth largest melon producer in the world and the third in Latin America. However, even with high melon production, the damages triggered by soilborne pathogens cause losses in production and yield and risk the abandonment of melon cultivated areas. Thus, to have improvements in quality and productivity, it is necessary to develop new techniques that can help in the management of soilborne pathogens, which are the main drive of losses in melon cultivation. Many control techniques are already being used to manage such pathogens, such as chemical, biological control, and the use of natural products; however, little is known about the use of green manure associated with polyethylene mulch to that end. Therefore, the objective of this work was to evaluate the effect of incorporating plant materials (Crotalaria juncea L. and Pennisetum glaucum L.) and commercial products (Compost-Aid® + Soil-Set®) to efficiently control pathogens transmitted via soil in melon production. In addition, we evaluated the responses of the soil microbiota (total fungi, total bacteria, sporulating bacteria, and total actinomycetes) to the above treatments. Two identical greenhouse experiments were conducted in a completely randomized design with seven treatments and seven replications. In conclusion, with this work, we were able to generate practical and theoretical information for producers to facilitate the management of the main soilborne pathogens that cause damage to the melon root system, optimizing techniques (mulch and green manure) that are already being used by the melon producers.
