The Relationship Between Yields On Farms And In Experiments

Abstract

A definite relationship appears to exist between the yields obtained on farms and in experiments. For crops the relationship is curvilinear and for animal products it is linear. In both cases the ratio of average farm yields to experimental yields decreases as experimental yields increase. The ratio between average farm and average experimental yields over a period of years decreases as the area of crops increases and varies with the type of animal product.
