Abstract: Lettuce (Lactuca sativa L.) is an important vegetable in Brazil, present in the diet of a large part of the Brazilian population and rich in vitamins and minerals. Nitrogen, which is essential for plant growth and quality, can be obtained in a sustainable way using legumes, which are rich sources of this nutrient, through Verdeponia. This study aims to analyze how the presence of leucena (Leucaena leucocephala (Lam.) from Wit) pruning waste in the substrate can influence the germination of lettuce (Lactuca sativa L.) seeds and the initial growth of seedlings. In this study we used Leucaena (Leucaena leucocephala (Lam.) de Wit) in two different ways to analyze the germination of lettuce (Lactuca sativa L.). We used 3 trays with 200 cells each, completely filled: one with pruning cuttings mixed with Tropstrato® HT Hortaliças substrate, one with leaves picked on the day mixed with the substrate and one with the substrate alone. Once the seed germination had stabilized, we divided them into 2 treatments (T1 and T2), containing sieved clay soil, and planted to monitor growth and carry out analyses of stem length, stem diameter and leaf area. The germination results indicate that the treatment using pruning and the one that contained leucena leaves harmed the lettuce plants compared to the control, which germinated more expressively, all of which were in a pleasant environment. In the second phase of the experiment, only the control and the treatment with leucena pruning were used, and statistical analysis showed that there was no difference in lettuce growth in either treatment. It was concluded that Leucaena leucocephala does not prove to be a good alternative substrate for lettuce during the germination stage, but it is a possibility during the initial growth of the seedlings.
