Principle 2: Does climate matter?
Seasonal rainfall plays a big role in determining where Simon decides to distribute maize and sorghum seed, two of the more important seeds his company distributes. Where the rainy season is long and moisture is ample, high yielding, late maturing maize does well. In fact yields can be twice that of sorghum under good conditions. But where rainfall is lower and less reliable, sorghum is preferred since it can survive drought when maize would fail completely. Farmers everywhere distribute their yield risk by planting come of each, with proportions determined by the average rainfall for their location (see map of average rainfall in the March to May period).
