Calculating the Grams per Head

At a young Stage before the Kernels on the Head Can Be Counted
Stand (plants/ha) Grams (kernels per head)
Once kernels on the head can be counted
To count the kernels per head:
  1. Measure the diameter of the head
  2. Measure the diameter of the disk flowers if applicable
  3. Count the number of kernels per 10 cm2 and divide that number by 10 to get the number of kernels per cm2

Calculate the productive area:
With the above, we can calculate the productive area as follows:
For example, let's use a diameter of 15 cm for the head and 5 cm for the disk flowers:

  • Total Area: 15 x 15 x 0.79 = 177.75 cm2
  • Unproductive Area: 5 x 5 x 0.79 = 19.75 cm2
  • Productive Area: 177.75 - 19.75 = 158 cm2
Calculate grams per head:

Now that we have the productive area, we:

  1. Multiply the number of kernels per square centimetre (cm2) by the productive area in order to get the number of kernels per head
  2. Multiply the number of kernels of the head by the average weight per kernel in order to get the mass of the head. A mass of 0.04 g/kernel can be used as a guideline

General Comments: It is important that the said masses are only regarded as guidelines and that one realises that it may be affected by factors such as appearance of the plant, climate, region, variety etc.
