Table 3. Projected biomass reduction of silage corn against the departure of soil temperature at planting and growing degree days at harvest

Departure	Silage corn maturity
	Early	Medium	Late
STP (Reduced biomass, Mg ha−1,%)
0	19.3 (100)	23.3 (100)	21.9 (100)
2	18.7 (97.1)	22.8 (97.8)	20.7 (94.7)
4	17.2 (88.9)	21.2 (91.0)	17.4 (79.6)
6	14.6 (75.5)	18.5 (79.5)	12.0 (54.7)
GDD (Reduced biomass, Mg ha−1,%)
50	19.9 (100)	18.3(100)	21.5 (100)
100	19.7 (99.2)	18.0 (98.2)	21.1 (97.9)
200	19.2 (96.4)	17.4 (95.3)	20.0 (93.1)
300	18.2 (91.6)	16.7 (91.3)	18.4 (85.5)

STP, soil temperature at planting; GDD, growing degree day.
