Available in PDF, EPUB and Kindle. Book excerpt: The literature which has been reviewed presented overwhelming evidence for the need to consider weather in agricultural experiments. The primary purpose of this study has been to find a single atmospheric-soil moisture stress variable which is correlated with final corn yield. It is hoped that the use of this moisture stress variable will facilitate and encourage the consideration of weather with other environmental and technological factors in agricultural research and extension. The consideration of the weather will help evaluate the spatial and temperal representativeness of experimental results. Two atmospheric-moisture stress variables were found to be highly correlated with unreplicated plot corn yields from secon year corn in the 4-year rotation experiment, corn-corn-oats-meadow, at the Iowa State University Agronomy Farm, Ames, Iowa. One of the variable was the number of days on which the corn was estimated to be under no moisture stress, in the period 6 weeks before 3 weeks after date of silking. The estimation of moisture stress or no moisture stress conditions was based on the experimental relation found by Denmead and Shaw (10). OTL = f(ETFC), where OTL is the percent available soil moisture below which the corn plant loses turgor. The amount of available soil moisture at the turgor loss point depends upon the atmospheric demands or the evapotranspirations at field capacity, ETFC. The ETFC was estimated from the daily evaporation form a weather Bureau class a evaporation pan. (...).
