Precipitation Enhancement Effects on Grain Sorghum, Using a Daily Growth Model

摘要

Application of a precipitation enhancement technology to provide additional water directly on crops and rangeland raises questions about the effects on crop yield of the amount and timing of additional precipitation. This paper presents the results of using a model simulatiNG the daily growth and development of a grain sorghum plant to investigate these effects. Data from five sites located in the central and southern High Plains were used. The model was exercised with observed precipitation and temperature and with 15 precipitation enhancement scenarios. These scenarios werE selected to provide a rang of precipitation conditions that could reasonably be expected from a weather modification program.
