This paper presents the results obtained in 1969 at the Centro Experimental de Campinas in a soil covering trial for strawberry (variety Campinas IAC-2712) grown on a Red Yellow Latosol. Six materials were compared as soil coverings, with bare soil as control. The total yield of June to December and also the partial one of June-July, when the prices of strawberry are the highest, because harvest begins and the fruits are bigger, were measured. Total yield on covered soil was increased in all treatments. The materials used were the following: rice plant straw, rice rind, dry grass (Rhynchelitrum roseum), sugar-cane residual, wood residual of joinery, and black plastic of 76 microns thickness. Statistical analysis of the data showed the following results: concerning total yield, the treatments with dead plant materials (with no differences among them) were superior to black plastic and bare soil. The black plastic covering was superior to the bare soil treatment. Concerning the partial production all covering treatments (with no differences among them) were superior to the bare soil treatment.
