The density of tomato cultivated on substrate is generally of 2.5 stems/m2. During cultivation, side shoots are selected to reach 2.8 stems/m2. To improve yields and profitability of cultivation, possibilities could be to raise the density by increasing the number of side shoots or to plant directly at a higher density. To answer this question, density tests were carried out at Agroscope Changins Wädenswil ACW in 2009 and 2010. In 2009, a standard variant, planted at 2.5 stems/m2 and increased to 2.8 stems/m2 by selection of side shoots, was compared to the same initial planting density increased to 3.5 stems/m2. In 2010, a variant directly planted at 3.75 stems/m2 was added. The raise of density from 2.8 to 3.5 stems/m2, respectively to 3.75 stems/m2 increased yields by approximately 15%. However, there was no significant production gain between the plantation at a low density with addition of side shoots and direct plantation at high density. Contrary to the yield, density slightly influenced fruit quality.
