Abstract
The objective of these trials were to evaluate suitable planting dates for hybrid sweet corn production on
paddy soil in Phatthalung province, hybrid sweet corn varieties ATS 5 and HN 27 were planted on the 19th of
February, March, June, and July. The results indicated that the sweet corn variety ATS 5 produced ear yield of
2,394 kg per rai than those of HN 27 was equal to 1,890 kg per rai. The February planting date had the highest ear
yield of 3,585 kg per rai. The two hybrid sweet corn varieties showed a satisfactory growth and yield in all
planting dates and produced ear yield higher than 1,450 kg per rai. The hybrid sweet corn variety HN 27 had the
number of large ear yield than ATS 5. In addition, the two hybrid sweet corn varieties have average sweetness of
14 % brix.
