The tomato crop started near Bucharest city, in a favourable area for vegetable growing, using 3 tomato crossbreeds, pruned with one and two stems in order to study their behaviour from the vegetative and fruit forming point of view. The biological material used for this particular experiment was 3 indeterminate, disease-resistant tomato hybrids, with fruits of roughly 150g, round and regular. The plants were pruned with two stems, the first one being the main and the second being formed from the first shoot located at the base of the plant. The crop was propped on trellis, with 5 clusters and mulched with agro textile material; the planting scheme was 100cm/40cm for variants pruned with two stems and 80cm/40 for variants pruned with one stem. The results showed that all studied hybrids had a satisfactory vegetative growth, proved by the height of the plants and their leaves, for both the main and the second stem. In what regards the formation of fruits, the plants with two stems provided a larger quantity. Thus, the number of fruits per plant was almost double for variants with two stems, the average fruit weight registered similar values for both treatments, but a considerably higher fruits yield was noted for Veneţia F1and Rhuen F1 hybrids.
