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
