Fig. 2. Ears ha-1 and kernel weight ear-1 as affected by hybrid and planting date (data are averaged across plant populations) at Garden City, KS from 1996 to 1999. Numbers within each graph indicate the LSD (0.10) of hybrid (H) and planting date (D). H1, H2, H3, H4, and H5 are hybrids with 75-, 92-, 98-, 106-, and 110-d maturity, respectively. D1 and D2 indicate planting dates in mid-April and early May. Ears ha-1 (darker bars) are plotted on the Y1 axis, and kernel weight ear-1 (lighter bars) are plotted on the Y2 axis
