Resumo: The objective of this study was to evaluate the effect of drought on biomass of different cover crops. The experiment was conducted in a greenhouse at the experimental campus of the Federal University of Piauí (UFPI), on soil classified as Yellow Latosol dystrophic. The treatments were composed by five species of cover crops (Brachiaria brizantha cult. Xarés; Pennisetum glaucum cv. ADR 300; Brachiaria ruziziensis; Mucuna aterrima; Pennisetum. glaucum cv. ADR 7010) and four irrigation intervals levels (2, 4 6 and 8 days). Independent of the levels of water deficit, the highest biomass were obtained in species B. brizantha, B. ruziziensis, P. Glaucum cv. ADR 300 and ADR 7010. There was greater tolerance of M. aterrima levels of water deficit. The species of B. brizantha and B. ruziziensis accumulated 70% of the dry weight of tops of sheets, while P. glaucum cv. ADR 300 and ADR 7010 accumulated 60% of the stem. Even with reductions in biomass under water deficit conditions, the species B. brizantha and B. ruziziensis have potential for soil cover and P. glaucum residues as a source for the maintenance of soil organic matter.

O experimento foi conduzido em casa de vegetação, na área experimental do campus da Universidade Federal do Piauí (UFPI), em solo classificado como Latossolo Amarelo distrófico. Os tratamentos foram compostos pela combinação cinco espécies de plantas de cobertura (Brachiaria brizantha cv. Xarés; Pennisetum glaucum cv. ADR 300; Brachiaria ruziziensis; Mucura aterrima; Pennisetum. glaucum cv. ADR 7010) e quatro intervalos de turno rega (2, 4, 6 e 8 dias). Independente dos níveis de déficit hídrico, as maiores produções de fitomassa foram obtidas nas espécies de B. brizantha, B. ruziziensis, P. Glaucum cv. ADR 300 e ADR 7010. Observou-se maior tolerância de M. aterrima aos níveis de déficit hídrico. As espécies de B. brizantha e B. ruziziensis acumularam 70% da fitomassa da parte aérea nas folhas, enquanto que, P. glaucum cv. ADR 300 e ADR 7010 acumularam 60% no caule. Mesmo com reduções da fitomassa em condições de déficit hídrico, as espécies de B. brizantha e B. ruziziensis apresentam potencial para cobertura do solo e o P. glaucum como fonte de resíduos para manutenção da matéria orgânica do solo.UEL2013-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1225110.5433/1679-0359.2013v34n6Supl1p3307Semina: Ciências Agrárias; Vol. 34 No. 6Supl1 (2013); 3307-3320Semina: Ciências Agrárias; v. 34 n. 6Supl1 (2013); 3307-33201679-03591676-546Xreponame:Semina.
