The occurrence of nematodes in lettuce cultivation areas has become a problem since these phytopathogens cause damage to the roots leading to losses in productivity. The use of plant extracts and antagonistic plants has been tested in order to reduce the nematode population in cultivated areas. Thus, the objective was to evaluate the effect of the use of marigold in the control of nematodes in two lettuce cultivars. The experimental design used was randomized blocks, in a 2x4 factorial scheme, two cultivars (Lucy Brow and Amanda) and four cultivation arrangements: Single lettuce, Intercropping in central line, consortium in alternate rows and mulch. The agronomic parameters evaluated were: Total productivity, commercial productivity, number of leaves, plant height and diameter, stem length and dry matter. As for the quantification of the nematode population, extractions were carried out in soil and roots. There was no statistical difference between the cultivars evaluated in terms of agronomic parameters, however the cultivar Amanda showed a reduction in the number of nematodes in the soil. Marigold mulch provided a smaller population of nematodes in both soil and root. In addition, the use of mulch showed better productivity in the analyzed cultivars, this due to the greater use of light, water and nutrients in the comparison of crops with cloves in the central line and intercropped.
