With abnormally cold temperatures both in the spring and in the fall, the most abbreviated growing season ever experienced took a heavy toll on production. Even with a full month delay in harvest, many bolls failed to open – a result of too few heat units to mature the late set. In these tests average yields of all carry-over entries were more than a bale an acre below that of the same variety the year before. In general, quality was not detrimentally affected, but because of the exceptionally adverse conditions varietal relationships, especially as it relates to yield, are not necessarily what might be expected in a more normal year…
