Abstract

This study is mainly focused on evaluating the effects of different rain protectors and broccoli varieties to find out whether rain protector and variety is suitable or not for broccoli production during rainy season. Broccoli was experimented at Prince of Songkla University, Hat Yai, Songkhla, southern Thailand. Study revealed that broccoli growing under plastic sheet and green shade net had lower incidence of soft rot disease (1.62 and 3.75%, respectively) than those grown in open field (13.33%) while their growing under plastic sheet (1.50%) had lower incidence of black rot disease than those grown under green shade net and open field (18.75 and 32.88%, respectively). All broccoli varieties were found to be statistically different in their response towards soft rot and black rot diseases. However, the Top Green had the highest diseases incidence (8.33 and 21.08%, respectively) while the Yok Kheo had the lowest diseases incidence (4.62 and 0.00%, respectively). The highest total yield was obtained from the Yok Kheo when those grown under plastic sheet (13.48 t/ha) while the Top Green had lowest yield when those grown in open field (3.94 t/ha). Therefore, the most suitable method for broccoli production during rainy season in southern Thailand was to grow under plastic sheet and green shade net by using the three varieties of broccoli.
