Bell pepper is a very important crop for its value in domestic and foreign markets. Actually, growers have adopted different management practices. In that aspect, management with different numbers of stems can define the quality and quantity of the product, as well as any increase in yield. The objective of this work was to evaluate the physical and chemical characteristics of fruits in terms of the quality and postharvest of bell pepper, as well as the yield according to the number of stems grown in a hydroponic system under greenhouse conditions. The experiment consisted of four treatments: two stems (T1) and three stems (T2) on a ‘Cannon’ cultivar, as well as two stems (T3) and three stems (T4) on a ‘Bragi’ cultivar. Fruits were sampled to determine total soluble solids (TSS), titratable acidity (TA), pH, electrical conductivity (EC), maturity index (MI), vitamin C (VC), lycopene content, size, shape, color, firmness, and yield. High vitamin C concentration of 120 mg 100 g<sup>−1</sup> was found in both cultivars. Treatments from ‘Cannon’ had the higher TSS content, lycopene levels and firmness. Regarding the physical characteristics, T1 of ‘Cannon’ had better fruit size: 63% (large), 35% (medium) and 2% (small). The highest yield was obtained in T2 of ‘Bragi’ with 6.50 kg m<sup>−2</sup>. It was observed that total number of fruits increased as the number of stems increased. However, the size of the fruits decreased.
