Abstract
Four broccoli (Brassica oleracea var. italica) varieties were evaluated in year round of Songkhla province, Thailand, from January, 2011 to January, 2012. The results shown that broccoli planting in all months provided high survival rate of seedling (78.90-98.24%). They had higher plant height than other months when planting in January, February, March, July and December (49.58-51.71 cm). Broccoli planting in January, February and March had the early time to 50% flowering and harvest of 33-36 and 43-45 Days after Transplanting (DAT), respectively. The Yok Kheo could respond to the best seedling survival rate and plant height while the Green Queen had the early time to 50% flowering and harvest. The Yok Kheo planted in January had the highest total yield (12.31 t/ha), followed by the Yok Kheo planted in March (10.65 t/ha) and the Top Green planted in January (10.50 t/ha), respectively. The Yok Kheo is a new interesting hybrid variety because it had higher total yield than the Top Green that is the popular variety of farmers in southern Thailand.
