Suppose peas are planted in Indiana on May 1. If the peas need 1200 growing degree days before they can be picked, and if the mean temperature for each day during May and June is 70°F, in about how many days will the peas be ready to pick? (Assume a base temperature of 40°F.) a. 11 b. 30 c. 40 d. 70

c. 40

Explanation:

Given that:

The mean temperature for each day during May and June is = 70°F ;   &

a base temperature = 40°F

Then the average temperature difference = 70°F - 40°F

= 30°F

That means the pea accumulate 30 growing degrees per day.

NOW, If the peas need 1200 growing degree days and accumulate 30 per day, then they will need 40 days before they are harvested

(i.e = 40)

Hence, if the pea plants are planted in Indiana on May 1, the peas will be ready on June 10.
