| Abstract | The increasing importance of water use in crop production had demonstrated the need for integrated studies of the water transport phenomena in the soil-plant-atmosphere system. Thus, this study was conceived with the primary aim of developing an index to soil moisture availability and crop production. Solution by finite difference approximation of the unsaturated one-dimensional vertical flow equation in the soil-root system in which a macroscopic root extraction term was incorporated paved the way to the development of a model for soil moisture determination. Actual transpiration rates obtained from simulation of the first model were used in a second model which has the capability of calculating potential and actual crop yields. Verification of the simulated results from the two models to measured data obtained from a field experiment conducted on the agricultural experimental field of the Asian Institute of Technology revealed that the two models are applicable to this part of the world. |
