File:Corn and soybean temperature response (ARS USDA).png

Summary

This image shows graphs of how the growth rate of <a href="https://en.wikipedia.org/wiki/corn" class="extiw" title="en:corn">corn</a> and <a href="https://en.wikipedia.org/wiki/soybean" class="extiw" title="en:soybean">soybeans</a> are affected by air temperatures. From the public-domain source: "For each plant variety, there is an optimal temperature for vegetative growth, with growth dropping off as temperatures increase or decrease. Similarly, there is a range of temperatures at which a plant will produce seed. Outside of this range, the plant will not reproduce. As the graphs show, corn will fail to reproduce at temperatures above 95 °F and soybean above 102 <a href="https://en.wikipedia.org/wiki/%C2%B0F" class="extiw" title="en:°F">°F</a>."

Both graphs show plant growth rates that rise and peak at a particular temperature, then fall off and decline. For corn, optimum vegetative growth occurs between around 77-99 °F, while for soybeans , it occurs between 77-97 °F. For corn, optimum temperatures for producing seeds (reproductive response) occurs between around 62-72 °F, while for soybeans , it occurs between 72-75 °F.
