Fig. 3. Effect of planting date on relative dry matter yield of winter triticale grown over two growing seasons at three Iowa locations. Relative yields are based on mean final dry matter yield of the highest-yielding planting date within each location and growing season. Growing degree days were calculated beginning at planting. Critical level was obtained using the Cate–Nelson test to separate the data into two populations. Regression then fitted lines to the two populations.
