Abstract
The experiment was carried out under protected environment from October, 2001 to March, 2002, at the Teaching, Research and Extension Farm (Ilha Solteira, São Paulo, Brazil) of the College of Engineering of Ilha Solteira, UNESP. The effects of fourplant spacing (30; 40; 50 and 60 cm) and three numbers of inflorescences per plant (3; 4 and 5) for tomato hybrid “Duradoro” were evaluated. The experiment was carried out in a randomized block design, in a split-plot array, with four replications. Results showed that the height of plants, at 30 and 50 days after the transplant (DAT), was not influenced by the spacing among plants. At 70 DAT, a linear increase of the height of plants with the reduction of the plant spacing was observed. The yield and the number of fruits per plant as well as the total yield and yield of fruits of medium size per unit area increased directly with the increase in the number of inflorescences. The reduction in the plant spacing increased the total yield of fruits and, also, the yield of fruits of large and medium size.
Highlights
Devido às facilidades e versatilidade de utilização, o tomate é a mais popular das hortaliças
Altura média de plantas de tomate aos 70 dias após o transplantio, em função do espaçamento entre plantas
A massa média do fruto variou de 155,3 a 170,0 g e não foi influenciada pelo espaçamento e número de racimo por planta
Summary
Devido às facilidades e versatilidade de utilização, o tomate é a mais popular das hortaliças. Pelo fato de limitar o número de racimos florais, a poda apical ocasiona redução na produção de frutos por planta e, conseqüentemente, na produtividade. As variáveis avaliadas foram: a) características fenológicas: altura da planta aos 30, 50 e 70 dias após o transplantio das mudas; altura de inserção do primeiro racimo; b) características da produtividade: produção total por unidade de área; produção de frutos graúdos (>70 mm), médios (50-70 mm) e pequenos (
