THE EFFECT OF PLANT DENSITY ON THE LETTUCE YIELDS GROWING IN THE GLASSHOUSE

Several trials of lettuce in the glasshouse, out of which three have been shown here, were carried out during the winter seasons of 1982/83 and 1983/84. Some varieties of butterhead lettuce were grown at different plant spacing.
Higher plant density than in nord-western Europe was used too.
The results have proved that higher plant density gives larger yields but the lettuce heads are smaller.
