A mathematical inquiry into the influence of the amount and distribution of rainfall on the yield of corn
1925
The data reported herein indicate the following under the conditions of the experiment at Blacksburg, Virginia. If the entire corn year is considered, an increase in rainfall, within limits, is accompanied by an increase in yield of corn. A study of the rainfall of the different months of the corn year in reference to yield indicates that alternate wet and dry periods are very favorable to corn production. It seems that a low rainfall in May and July accompanied by a high rainfall in June and August is conducive to a high yield of corn. Ample rainfall before earing time, in June, is very beneficial to corn production as is abundant rainfall during earing time, in August.
