Task: Class Definition Understanding (ontology: Food_Agriculture/Crop_Ontology)

Which of the following definitions best describes 'Seed yield productivity rate method'?

A. Compute specific root length as root length/root biomass.
B. Compute pod harvest index = seed biomass (yield) DW basis at harvest / pod biomass DW at harvest x 100
C. Standard protocol of biomass sampling, compute leaves biomass at R8 in kg/ha using the biomass component (dried to constant weight at 60C) from sampled area (0.5 m of a row).
D. Compute seed yield rate as seed yield per hectare divided by days to physiological maturity.

Answer: Compute seed yield rate as seed yield per hectare divided by days to physiological maturity.
