Morphological changes in five clonally propagated genotypes
of Agrostis L. resulting from variations in environment were
studied in six natural environments extending from southern Oregon
to northern British Columbia. These same clones were also subjected
to four different cutting heights in turf plots. In addition to
the field experiments, they...
A taxonomic investigation was made of 24 taxa belonging
to the section Trichodium (Michx.) Trin., of
Agrostis, and the genus Podagrostis. Experimental methods
were employed, including: uniform garden culture of transplants
and plants grown from seeds collected in natural
populations; breeding studies; physiological and phenological
investigations; cytological studies; ecological
studies...
Herbicides were tested for the selective control of bentgrass in
Kentucky bluegrass turf under three levels of competition. Best control
in zero competition was obtained with a winter treatment of
bromacil at two pounds per acre. Under circumferential and direct
competition, best control was obtained with a summer and fall...
Good management practices are essential if optimum fertilizer responses are to be realized. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Follow recommended soil sampling procedures to estimate fertilizer needs. The Oregon...
