Synopsis Most of the yield variations resulted from differences in second‐ear yield when a significant number of second ears were produced. First‐ear yield was relatively unaffected by environment unless the crop was so poor that few second ears developed. Variations in second‐ear yields resulted primarily from differences in number rather than size. The plants tended to develop a fullsized first ear, and any additional yield came largely from second ears.
