This study was conducted in the Department of Horticulture and Experimentation at the University Jose do Rosario Vellano (UNIFENAS) in Alfenas-MG, Brasil in order to evaluate the formation of lettuce seedlings in trays filled with different substrates. The materials used to compose the substrates were pig bed base with wood shavings (M), pig bed with base coffee straw (C), earthworm humus (H) and commercial substrates Nutriorg (R) and Plantmax (R) The use of these pure substrates and various mixtures permitted the formation of 18 substrates that constituted the treatments. The experimental design was a completely randomized design with three replications. The lettuce seedlings were formed with the lettuce cultivar Regina. The seeds were sown in trays with 128 cells filled with the substrates under study. Each experimental unit was compost of 64 cells. The conduct of the experiment was within a protective structure of 85 m 2, model chapel with transparent plastic cover 100 microns thickness, additives against ultraviolet rays. After 30 days of sowing, ten seedlings were harvested randomly within each experimental unit for evaluating the number of leaves and the plant height. It was also evaluated the fresh and dry mass of aerial part and fresh and dry mass of root. It was concluded that the substrate T1 - M met the best features for the formation of lettuce seedlings in trays of 128 cells.

Once the use of historical data serves as an articulator of senses in journalistic narratives, this article proposes to study the cases in which the discursive constructions of the future are structured from the evocation of the past. It is possible to discern how images of the future built on stories parting from the past is related to a specific conception of history and how this history is seen, by journalism, as a repository of examples enrolled in a temporal continuum and fixed as a judging instance able to measure and anticipate the future consequences.
