Abstract

Grateful acknowledgment is extended to Iowa State University Agronomy Department for financial and material assistance that made this research possible. Thanks also to my fellow workers, Anthony J. Maves, and Ronald E. Secrist, for their ideas, encouragement and friendship. Most of all, I wish to express my special thanks and appreciation to my parents, Ellen and Richard, and my grandmother Emma, and to Coralyn and Charles Radatz, for their influence and love. Last but not least, to my dear son, Cliarlie, in spite of his computer operation assistance, and my friend and wife, Caryl, for her encouragement and understanding.
