摘要：The trial was aimed to select suitable planting times when broccoli varieties could resist well to soft rot and black rot diseases during dry season was studies at Prince of Songkla University, Songkhla, Thailand, from January to June, 2011. Split-plot in randomized complete block design was used in this experiment with four replications. The results showed that the lowest incidence of soft rot disease was observed in all broccoli varieties when they were planted in January (4.19-7.18%). After that, it would increase (22.59-45.58%) but the incidence of black rot disease was not increased when planting was done in January, February, March and June. The incidence of black rot disease was highest in April (84.24-92.64%). The Yok Kheo was produced the highest total yield when the planting took place in January and March (12.31 and 10.65 t/ha, respectively). The Yok Kheo is an interesting new hybrid variety. Its higher yield was than Top Green which is popular variety grown in southern Thailand. The yield of Green Queen was not significantly different from Top Green. It can be harvested at 11.67 and 9.38 days earlier than Top Green and Yok Kheo, respectively.
