The objective of this work was of evaluating three textures of mixed organic compost in the lettuce seedlings formation, cv. Babá de Verão, in trays of 72, 128 and 200 cells. An experiment was carried out in a greenhouse of the Plant Sciences Department at Universidade Federal Rural do Semi-Árido (UFERSA). A completely randomized experimental design was used with the treatments in 3 x 3 factorial scheme with three replications. The treatments consisted of combination of three textures of mixed organic compost, obtained by passage in mesh sieves n°4 (6mm), n°8 (4mm) and n°12 (2mm), with three trays of 72, 128 and 200 cells. Evaluations for seedling height, root length, number of leaves per seedling, leaf area, shoot fresh and dry mass, root fresh and dry mass were determined. Higher mean values of root length and root fresh mass were obtained in mesh sieve n° 8 (4 mm) combined with tray of 72 cells. Higher mean value of root dry mass was obtained in mesh sieve n° 12 (2 mm) combined with tray of 72 cells. Higher mean values of seedling heigh, shoot fresh mass, leaf area and root dry mass were obtained with tray of 72 cells. Higher mean value of root dry mass was obtained in mesh sieve n° 8 (4 mm).
