Resumo

The effect of soil mulching with transparent, black, white, and co-extruded white-on-black polyethylene sheets on soil temperature and tomato yield was evaluated in the Subtropical Central Region of the Rio Grande do Sul State, Brazil. The experiment was carried out from August 21, 1994 to December 2, 1994 in a 10m x 25m nonheated plastic greenhouse located at the county of Santa Maria. Highest soil temperatures were obtained under transparent mulch. Maximum amplitude of soil temperature waves was smaller under opaque mulches. Tomato yield was not significantly affected by mulch treatments, however, a tendency of greater yield was observed for opaque mulches as compared to transparent mulch. Among opaque mulches, the highest yield was obtained from white mulches.
