Description
An experiment with 6 varieties of wheat concerning the treatment of a
fungus attack was carried out on an experimental field with 5 blocks each
consisting of 12 plots. The experimental design and the yield (hkg/ha) for
each plot are given in the following table, where the treatment (T=treated,
U=untreated) and the variety (an=anja, ci=citadel, ko=kosack, kr=kraka,
sl=sleipner, vu=vuka) are also given.
