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

Which of the following definitions best describes 'Legume fruit yield per plant computation'?

A. Description: Record the days to flowering (DTF) post defoliation

 Materials:

 Dependent on: Plant defoliation event date msr [ISO 8601], Plant flowering date est [ISO 8601]

 Protocol:
 1. Record the number of days that have elapsed from the defoliation event date to the flowering date.
 2. Express DTF as an integer.
B. Description: Record the moisture content of a forage sample

 Materials:

 Dependent on: Forage dry mass [kg], Forage fresh mass [kg] | Forage subsample dry mass [g], Forage subsample fresh mass [kg]

 Protocol:
 1. Sample forage according to your sampling protocol.
 2. Weigh both the fresh weight of the forage as well as the dried weight of the whole sample, or if a large quantity, just a subsample.
 3. Find the difference between the fresh mass and the dry mass and divide by the fresh mass.
 4. Multiply by 1000 if expressing as g/kg or leave as is to express as g/g or kg/kg.
C. Description: Record the seed yield per plant

 Materials:

 Dependent on: Seed mass msr [g], Plant number cnt [n], Seed moisture content [%]

 Protocol:
 1. Sample plants according to sampling protocol.
 2. Place whole plant through a large bundle thresher (Almaco, Vogel,etc.) or even strip all fruit off by hand.
 3. Remove the seeds from the pericarp.
 4. Clean seeds using sieves and/or blower columns and/or indent cylinders to remove all foreign material.
 5. Finally, weigh the seeds and divide by the number of plants threshed.
 6. Report at seed moisture content.
D. Description: Compute the total yield of legume fruit per plant

 Materials: clippers, bundle thresher, sieves/blower columns, laboratory balance

 Dependent on: Legume fruit mass msr [g], Plant number cnt [n]

 Protocol:
 1. Divide the total mass of a sample of legume fruit by the number of plants they were sampled from.
 2. Express yield as g/plant

Answer: Description: Compute the total yield of legume fruit per plant

 Materials: clippers, bundle thresher, sieves/blower columns, laboratory balance

 Dependent on: Legume fruit mass msr [g], Plant number cnt [n]

 Protocol:
 1. Divide the total mass of a sample of legume fruit by the number of plants they were sampled from.
 2. Express yield as g/plant
