 The trial was conducted at two locations on the
agronomy farm on the campus in 1984. The class was
divided into six teams, each consisting of four members.
Each team conducted an experiment using a randomized
complete block design at each of two locations. Because
the teams managed their trials differently, each trial at
each location is considered a farm for purposes of
analysis. Hence, there are twelve farms included in the
trial. Data are shown in Table VII-7.




 The linear equations calculated for each of the
treatments are of the form

 Y = a + be
