ABSTRACT
Thus the temperature range and degree of temperature uctuation in an area can set limits on the crop species and cultivars that a farmer can grow, and can cause variations in quality and average yield for the crops that are grown. In selecting crops, it is necessary to consider the range of temperature conditions that might occur from day to day, between day and night, and from season to season. And one must be concerned with both aboveground temperatures and those belowground. Farmers need to consider also the many ways in which it is possible to modify the temperature environment in which crops grow. Putting all these variables together, it can be seen that agroecosystem management with respect to temperature involves potentially complex interactions among management actions, plants’ responses to temperature, the potential range of temperatures in a region, and the actual temperatures to which crops are exposed.
