Introduction

Agro-ecological Regions

    • Grouping relatively homogenous regions in terms of soil, climate and physiography and conducive moisture availability periods (length of growing season)

Length of Growing Period

    • Average duration when moisture availability allows crop growth.
    • RF/ PET ratio exceeded 0.50
