Carbon Dioxide

This photo clearly demonstrates that the amount of CO2 affects the crop yields. An increased amount of carbon dioxide (or a higher concentration) causes an increase in the rate of photosynthesis. However, there reaches a point where the rate cannot go any higher.

Temperature

It is apparent that when the temperature is increased, the rate of reactions taking place inside the crops increases as well, increasing the growth rate. As mentioned, there is an optimal temperature. However, too much heat can cause the plant to dehydrate, as well as causing the plant to grow badly. The enzymes can denature.
