Experiments with Flax - 1960

Experiments with flax at the Dickinson Experiment Station in 1960 included a varietal field plot trial of 9 varieties and the Uniform Regional Flax nursery.

Field Plot Trials

Lack of adequate July moisture and excessively hot weather in July reduced flax yields considerably. Highest yielding varieties were B5128 and Norland.

Yields from the flax variety trial are summarized in Tables 24 and 25.

Nursery Trials

Yields in the Uniform Regional Flax nursery ranged from 7.3 to 2.3 bushels per acre this year. Data from the Uniform nursery planting are given in Table 26.

One of the biggest obstacles to flax production on old land is competition from both grassy and broadleaved weeds. Crop failures in 1954, 1956, and 1957 were due largely to weed competition and various seasonal conditions which made chemical weed control impractical or impossible without damage to the crop. Lack of adequate moisture and excessively hot weather in 1959 damaged the plots so severely, they were considered a total failure.
