【 摘 要 】

The effects of branch number and plant densities on organically grown cherry tomato yield and fruit quality were studied. Labor costs for pruning were also assessed. The essay was conducted at the experimental fields of the Universidade Federal Rural do Rio de Janeiro, Brazil, from September 2004 to January 2005. A factorial design was used combining three row spacings (0.4, 0.6 and 0.8 m), two cherry tomato cultivars (hybrid 'Super-Sweet' and a local self pollinated 'Perinha') and three pruning regimes (free growth, one branch per plant and two branches per plant). The row spacing treatment of 0.6 x 1.5 m resulted in lower number of fruits when compared to the 0.4 x 1.5 m treatment, however, producing fruits with higher individual average mass, which resulted in similar final yield. These yields were higher than the 0.8 m treatment. Yield increases due to the higher number of plants per area were mostly due to the increase of fruit number, which compensated for the decrease of fruit size and mass. The 'free growth' treatment yielded similarly to the two branches per plant treatment. The labor costs were lower under 'free growth' due to the absence of pruning. Both cultivars responded similarly to plant population and pruning regimes.
