Abstract

ABSTRACT: Substrates are an alternative source of nutrients for plants that have demonstrated adequate characteristics for the germination and development of vegetable seedlings. The objective of the work was to evaluate the germination potential of arugula (Eruca sativa L.) seeds in different types of substrates. The experiment was conducted in a greenhouse with shade (50% brightness) in the experimental area of Campus I of the State University of Alagoas - UNEAL, the experimental design was in randomized blocks with 5 treatments (T1 = fine sand, T2 = humus earthworm, T3 = goat manure + earthworm humus, T4 = goat manure + humus, T5 = control soil), and 30 experimental units each. Broad leaf arugula seeds were used, where they were sown in polystyrene trays, the data on the amount of germinated seeds were recorded daily and subjected to the means comparison test using the Tukey test at the level of 5% probability with the help of the SISVAR statistical program. The% PG germination percentage and the IVG - Germination Speed Index were higher in the sand, earthworm humus and soil treatments (control), with no significant difference between them, whereas the humus + goat manure and humus + bovine manure treatments had the lowest averages in both variables. It is inferred that the use of humus earthworm, sand and soil (control) substrates significantly promoted arugula seed germination, while humus + goat manure and humus + bovine manure substrates reduced germination.
