and Interests |

| Michael
Ottman received his Ph.D. in Agronomy from the University of Illinois.
He also has a Master's degree in Vegetable Crops, which he received
from the University of California, Davis and a Bachelor's degree in
Plant Sciences, also from the University of California, Davis. His
research and extension interests are to increase crop production efficiency
through knowledge of basic plant processes and improved agronomic
practices. In particular, he is interested in irrigation management
and its effect on crop physiology, the relationship between nitrogen
and grain protein in wheat, environmental influences on crop growth,
and crop rotation effects on soil properties. Dr. Ottman's work has
been seen in such publications as New Phytologist and Agronomy Journal
