Correlating Degree Days to Crop Production
Question: I was wondering if one could loosely correlate degree days to crop production over the province of BC. Realizing that just because you have a certain degree day does not mean that that location might be right for the crop, but crops wouldn't require different degree days in different locations of BC correct?
Answer: Very loosely yes, but consider differences in rain, daylength, sunshine and crops. Some crops respond more than others to high temperatures. Also differences in tolerating low temps and differences in maturity. Better for comparing when other factors are controlled for. Where temperature is a main factor it will work better.
