Tansy ragwort (Senecio jacobaea L. ) is a poisonous weed which
infests alfalfa fields in western Oregon. Studies were conducted to
evaluate the effectiveness of asulam (methyl sulfanilylcarbamate)for
control of tansy ragwort in alfalfa and to elucidate factors responsible
for its selectivity. In seven replicated field trials in 1973 and...
Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...
Two cultivars of tall fescue (Festuca arundinacea
Schreb.) with contrasting growth habits were studied under
field and growth chamber conditions. Fawn, an established
cultivar since 1964, and TFM, an experimental line, were
observed to grow better during spring and fall months
respectively, in the field. Different temperature regimes
of 10/4,...
