1Keiser = Northeast Research and Extension Center
Rohwer = Southeast Research and Extension Center - Rohwer Division
Kibler = Vegetable Substation
2Abnormally hot and dry conditions reduced yields and uniformity at all locations. Because of these conditions, the results of the nonirrigated tests at Rohwer and the Starks Farm are not reported.
