Focusing on interpreting the main effects of fertilizer andirrigation method is the best way to understand the influence ofthese two factors on biomass yield.
Different fertilizers result in different average biomass yieldfor any irrigation method.
The change in average biomass yield that occurs when we changefrom one fertilizer to the other is not constant for bothirrigation methods.
Changing from one irrigation method to the other produces achange in the average biomass for any of the fertilizers.
QUESTION 5
Note: When creating the interaction plot, usefertilizer as the x axis factor.
Under irrigation method A, there is no clear change in the meanbiomass yield when we try different fertilizers.
Under irrigation method B, there is a large increase in averagebiomass yield when we change from fertilizer 150 to 200 , however,there is no clear change in yield when irrigation method A is usedand the same change in fertilizer occurs.
When fertilizer 100 is applied, there is an increase in the meanbiomass yield when we change from irrigation B to A.
The average biomass yield has a different value for all sixcombinations of fertilizer and irrigation.
