Current Position and Research Program:

Dr. Samuel Essah is the program leader for the Potato Management and Physiology program at the San Luis Valley Research Center.

The mission of the Colorado Potato Cultivar Management and Physiology program is to develop cultural management guidelines for the successful, sustainable and economic production of newly released and existing potato cultivars, as well as advanced potato selections that have the potential of being released, through field and laboratory research.

Information generated from Samuel’s program reveals management practices that are agronomically sound, economically advantageous, and environmentally responsible, while optimizing potato tuber yield and quality.  When management guidelines are tailored for individual cultivars it leads to the successful, sustainable, and economic production of the cultivar, which results in the optimization of its genetic potential, while minimizing economic inputs and environmental degradation.

Samuel’s research enables him to work closely with growers and other potato industry personnel.
