Permanent rye experiment

In 1906 a long-term experiment was started on a field of the experimental farm Groß-Enzersdorf. It is a 2factorial experiment with (I) crop rotation and (II) fertilization as factors. The treatments of the factor rotation are (a) permanent rye cultivation or (b) a 3field crop rotation of rye, spring barley and a fallow field. The levels of fertilization are (a) an unfertilized control, (b) mineral fertilizer, (c) organic fertilizer (manure) or (d) a combination of mineral and organic fertilizers. The plot size is 20 x 16 m. Unfortunately at that time when the experiment was started, statistical aspects were not considered, thus no replications were established.
