Study design

Study 2

Cold room (12oC) and store room (ambient temperature) can be considered as main plots, packaging methods (polyethylene bag, mesh bag or box alone) as sub-plots and factorial combinations of organic fertiliser and landrace as sub-sub plots. Within each of the cool and store rooms packaging method was replicated three times.

The skeleton analysis of variance table is shown here for each monthly sampling time. Strictly speaking the replication term should appear at the subplot level. We cheat slightly by pretending that we used three separate cold rooms and three separate store rooms. In this way the replication term is represented at the main plot level.
