Descrição: dc.descriptionWith the objective of evaluating the biomass production and nutrient removal by plant cover in the Agreste region of Alagoas, an experiment was conducted in the experimental field of the Federal University of Alagoas - Campus Arapiraca. Randomized block design was used, with eight treatments and four replications. The treatments were: Crotalaria juncea, Crotalaria spectabilis, Cajanus cajan (L.) Mill sp., Cajanus cajan, Canavalia ensiformis, Dolichos lablab, Mucuna aterrima and the spontaneous local vegetation (control). The green matter in an area of 1 m(2) during the flowering of each species was evaluated, and biomass was then dried in an oven at 65 degrees C until constant weight for dry matter, in which the contents of macro and micronutrients were extracted. Leguminous plant showed potential for use as green manure in the Agreste region of Alagoas, with N contents higher than the spontaneous vegetation and not being different from one for the accumulation of P, K, Ca, Mg, S, B, Mn and Zn. The spontaneous vegetation was similar to dry matter of legumes production. Among the treatments Cajanus cajan showed higher dry matter production and N accumulation in the aerial part.-
