Moisture availability and crop production.

摘要: ABSTRACT THE level of crop production de- pends upon many factors. One the important influences is degree moisture adequacy or deficit. The effects timing water deficits during various stages growth are briefly described. Providing not critical periods, there a surprising uniformity response to as measured by which evapotranspirative demand, ET, met. Methods for estimating ET and dependability rainfall given. A tentative classification climate agricultural presented.
