POP = Plant population, pre-three leaf stage.
HEA = Total heads (includes those that were white).
WHE = White heads.
HES = HEA/POP.
HGT = Height at harvest.
TEW = Test weight.
YIE = Grain yield, combine sample.
STR = Straw yield, from square meter samples.
YIM = Grain yield, from square meter samples.
KPH = Kernels per head, calculated from HEA, YIM, and TKW from YIE.
TKW = 1000-kernel weight, combine sample
NEG = Nitrogen concentration in grain, combine sample.

(All weights are expressed on an oven-day basis.)
