Resumo

The objective of the present study was to evaluate the influence of different plastic covers on microclimate and cherry tomato yield in greenhouses. The experiments were carried out in Piracicaba, state of Sao Paulo (Brazil), during three growing periods (2008/2009/2010). A greenhouse was divided in: Environment I (EI) - covered with plastic film anti-UV and thermo-reflective shading screen, and Environment II (EII) - covered with diffusive plastic film; monitored with automatic weather sensors; and cultivated with cherry tomato ('Sweet Grape' and `Sweet Million'). Use of diffusive plastic in greenhouses provides a better inside distribution of solar energy without causing major changes in air temperature and relative humidity, resulting in higher yield (kg plant(-1)), fruits quantity (number plant(-1)) and fruits average weight than those obtained under thermo-reflective shading screen.
