Abstract
Research was carried out during 1985–1987 to evaluate the influence of different cultural practices on earliness of ripeness and yield of fresh market tomatoes grown in a protected environment for early production.
The soil mulching with black PE film did not affect the growth and yield characteristics of the plants.
An increased earliness of production and a reduced length of the crop cycle were caused by drastic pinching (above the 1st or 2nd truss), but a fairly modest unit yield was given, compared to traditional pinching at the 4th truss.
This response could be in part obviated with the increase in crop density.
This allows a yield rise, but at the same time, causes a reduction in plant production because of the smaller number of fruit, which also weigh less.
Advantages on some fruit characteristics (e.g. mean weight and size) that gave better marketable and total yields were noted with an increase in the number of leaves left above the highest truss.
However, the more the leaves, the later the fruit ripening, Trellissing the plant was a useful practice in traditional crop with plants pinched at the 4th truss, but was of little importance when plants were pinched very low and grown at high density.
