This three credit hour course is intended to provide an overview of citrus and date culture in Arizona. A brief introduction to the genetics, taxonomy and botany of the crops and their history will be followed by an overview of established and promising cultivars and rootstocks where appropriate. Production practices will be covered in detail, including site selection, propagation, planting training, pruning, nutrition, water relations, pest control, harvesting, worldwide production, economics and marketing. Emphasis will be placed not only on the practical aspects of each cultural practice, but also on the biological basis for the practice. Students will be able to utilize sound plant biological knowledge when decision making.
