Harvesting Variety Trials
Quick Science facts:
| Plant Variety trials |
| These are proper science…. |
| Scientist want to find which variety is best. |
| Variety is the variable they want to change. |
| They want to measure the OUTPUT variable = YIELD |
| They need to make this a FAIR TEST by controlling the variables… |
| So they want to control all the INPUT or INDEPENDANT variable that could affect the yield: – Soil – Weather – How Planted – Fertiliser – Disease control |
| Part of doing this is to replicate there trials to allow for soil type, aspect etc |
| They then measure the OUTPUT or DEPENDANT variable = Yield |
