ABSTRACT
Rainfall shelters (shelters) have been used during the past 50 yr to exclude rainfall and other precipitation from research plots and lysimeters. They bridge the gap between the controlled environment of a greenhouse or growth chamber and uncontrolled field conditions. Meteorological variables such as radiation and wind are altered under the shelter,[1] but with limited rainfall duration, the effect on crop growth is minimal. The main limitation of rainfall shelters is the small crop area that requires careful extrapolation of results to field areas.
