Fig. 3. Silage dry matter (DM) (Y) accumulation as a function of number of days after silking (DAS; X). Each data point is the average of two densities and four replications. The overall curve was fitted to a quadratic-plus-plateau model: Y = a + bX – cX² when X < X₀, and Y = Y_max when X X₀. Hybrids Pioneer 37M81, Maizex Leafy 4, and TMF94 were in common in all years while Max 86 used in 1999 and 2000 was replaced with N.K. Enerfeast I (non-Leafy silage corn) in 2001 and 2002.
