Agricultural potential estimated from the ratio of actual to potential evapotranspiration



Agricultural potential estimated from the ratio of actual to potential evapotranspiration



Agricultural Meteorology 13(3): 405-417



The R-index, defined as the ratio of actual evapotranspiration (Et) and potential evapotranspiration (Ep), was a useful measure of plant water supply in relation to plant water demand and could also be used to indicate soil moisture conditions. The R-index had a distribution which closely followed the Beta distribution function. The R-index and its probability distribution could together be used to assess land use feasibility and irrigation potential requirements for selected crops.
