THE EFFECT OF PLANT DENSITY ON THE LETTUCE YIELDS GROWING IN THE GLASSHOUSE |
| Authors: | V. Martinac, J. Borošic |
| Abstract:
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. | |
