Proceedings [...]. Niterói: AGRHA Consulting, 2023. p. 65-68.c2023  aVetiver grass is used throughout Asia to make handicrafts, medicines, and other products. It is widely used in several countries for its deep and abundant root system, sediment control and phytoremediation. Lithothamnium is derived from seaweed and contributes to soil improvement. The objective of this study was to analyze the effect of different doses of Lithothamnium on the growth parameters of vetiver grass in clay and sandy soil. For the experiment, twenty pots were used for each type of soil (sandy and clayey), where each pot contained a vetiver grass seedling. It was separated into 5 treatments per block: 0, 10, 20, 40, 80, g of Lithothamnium per pot, and the growth parameters were analyzed. Regarding height, only the clay soil showed statistical differences between treatments on days 4 and 5; The sandy soil did not show significant differences. For fresh and dry mass, only the grass grown in the sandy soil showed a significant difference. Thus, Lithothamnium did not show the expected effect for the grass, since it remained at the level of control in relation to the different treatments for the parameters analyzed.  aClay  aVetiveria Zizanioides  aSandy1 aCORRÊA, G.
