Currently, it is aimed to use substrates composed primarily of organic waste in order to reduce costs with chemical fertilizer. In that sense, the experiment was to evaluate different types of substrates for the emergence and early development of seedlings of Cassia granais L. f. The experiment was carried out in a greenhouse at the Departament of Vegetable Sciences of Federal Rural do Semi- Arido (UFERSA), in Mossoro, Rio Grande do Norte state, Brazil. The substrates used were: sand + carbonized rice husk (in ratios of 1:1, 1:3 and 3:1), plant sand + wood dust (in ratios of 1:1, 1:3 and 3:1), plant sand + coconut fiber (in ratios of 1:1, 1:3 and 3:1), plant sand + chestnut bark (in ratios of 1:1, 1:3 and 3:1) and plant sand (control). The experimental design was a completely randomized design with 13 treatments (combinations of substrates), with four replications of 25 seeds and the means to test for Skot-knot (pr
