Abstract
The objective was to evaluate strawberry productivity under different soil cover, as well as its effectiveness on the weed control in an organic production system. The experiment was conducted in the Universidade Federal da Fronteira Sul - UFFS, campus Cerro Largo. The random blocks delineation with 6 blocks was used. The units were designed using 10 “aromas” cultivar plants, planted in 4 interspersed lines each 0,3m apart. The treatments used were whole plants of Sudan grass (Sorghum sudanense), shavings, acicula of Pinus (Pinus elliottii), black polyethylene and uncovered soil. To determine the productive aspects, the mass production, number and size of fruit were evaluated. The effectiveness of the weed control under different soil cover was determined through the dry weed mass collected monthly. With the exception of the sudan grass, all the other treatments statistically matched the productive aspects. The black polyethylene cover presented better weed control.

Summary
Jeferson Tonin[1], José Tobias Marks Machado1*, Lisiane Sobucki[2], Jorge Atilio Benati[2], Bruna Rohrig[2] e Evandro Pedro Schneider[2]. Este trabalho teve o objetivo de avaliar a produtividade do morangueiro em função de diferentes coberturas de solo e a efetividade destas sobre o controle de plantas daninhas, em sistema orgânico de produção. Cada parcela foi constituída por dez plantas da cultivar Aromas, dispostas em quatro linhas intercaladas, distanciadas em 0,30 metros. Os tratamentos utilizados foram plantas inteiras de Capim Sudão (Sorghum sudanense), maravalha, acícula de pinus (Pinus elliottii), polietileno preto e solo descoberto. Para a determinação dos aspectos produtivos foram avaliadas a produtividade em massa, o número e o tamanho dos pseudofrutos. A efetividade de controle das plantas daninhas pelas diferentes coberturas foi determinada através da massa seca das plantas coletadas mensalmente. Com exceção da cobertura com Capim Sudão, todos os demais tratamentos se equiparam, estatisticamente, nos aspectos produtivos. A cobertura com polietileno preto apresentou maior controle sobre plantas daninhas. PALAVRAS-CHAVE: Fragaria X ananassa, mulching, produção de base ecológica
