Irrigation is an important part of successful vegetable crop production.
Even in a year with average or above-average rainfall, crop stress may occur during some stages of crop growth. When moisture stress occurs during a critical stage of crop growth yields and crop quality can be adversely affected. Whether it is lack of soil moisture or too much water proper use of irrigation is necessary to produce crops to their highest yield and quality potential. Although plants should not be subjected to inadequate moisture at any growth stage some times are more important than other stages of development. In peppers, low soil moisture during flowering or fruiting can cause flower bud abortion, malformation, or blossom end rot.
