Resumo
The aim of this work was to evaluate the effect of two combinations between plant density and
tip pruning height, associated to the use of plastic mulching, on plants development and fruit yield of
the tomato (Duradoro hybrid) grown under protected environment. Two single stem cultivation systems
were compared: SC1 - tip pruning after the fifth inflorescence with 20,000 plants ha -1 ; SC2 - tip pruning
after the second inflorescence with 50,000 plants ha -1 , and three different soil cover conditions: bare soil,
white polyethylene film, 50 mm-thick, and black polyethylene film, 50 mm-thick. The experimental design
used was randomized block, in a split plot array. The work was carried out from June to November of
2003, at the UNESP, Ilha Solteira (São Paulo State, Brazil). The treatment SC2 increased plant height at 45
days after the transplant, and reached higher number and fruit yield, with reduction in cropping period.
The soil cover with polyethylene mulching did not affect the yield of this crop.
