Effects of Hybrid Maturity, Planting Date, and Plant Population

Southwest Res. Ext. Cent., 4500 E. Mary, Garden City, KS 67846

View larger version (37K): [in a new window]   Fig. 1. Ears ha-1 and kernel weight ear-1 as affected by hybrid and plant population (data are avg. across planting dates) at Garden City, KS from 1996 to 1999. Numbers within each graph indicate the LSD (0.10) of hybrid (H) and population (P). H1, H2, H3, H4, and H5 are hybrids with 75-, 92-, 98-, 106-, and 110-d maturity, respectively. Ears ha-1 (solid lines) are plotted on the Y1 axis, and kernel weight ear-1 (dotted lines) are plotted on the Y2 axis

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

Kernels ear-1 and kernel wt as affected by hybrid and plant population (data are averaged across planting dates) at Garden City, KS from 1996 to 1999. Numbers within each graph indicate the LSD (0.10) of hybrid (H) and plant population (P). H1, H2, H3, H4, and H5 are hybrids with 75-, 92-, 98-, 106-, and 110-d maturity, respectively. Kernels ear-1 (solid lines) are plotted on the Y1 axis, and kernel weight (dotted lines) are plotted on the Y2 axis
