Ten tomato cultivars (fresh market) were grown in a greenhouse using 30 cm or 45 cm in-row spacing with rows spaced 60 cm apart in 1979 from January through June. The cultivars were Big-O, Bigset, Hotset, Monte Carlo, Petra, Stella, Supal, Tropic, Wilters Villmarie, and WW200. Cultivars producing high number of fruit had lower fruit weight. Seven cultivars produced more fruit under the 30 cm spacing. Six cultivars produced slightly heavier fruit at 45 cm spacing and five cultivars produced larger class sized fruit at 45 cm spacing. Five cultivars had fruit by cluster distribution significantly higher up the plant at 45 cm spacing, while two were significantly lower. Three cultivars had greater production later in the growing period at 45 cm spacing, while two were greater at the beginning.
