An "index of competition" is derived that can be used to estimate crop loss due to weeds when weed and crop species, density of weed stand, and expected weed-free yield are known. Experimental data are used to derive this index for wild oats (Avena f

Moisture and temperature differentially affected the phytotoxicity of four herbicides to tartary buckwheat, Fagopyrum tataricum (L.) Gaertn., the test plant. The activity of the systemic herbicides 2,4-D, dicamba, and picloram was greatest when condi

Tests were conducted over a 4-year period with Vantage and Olli barley to determine the earliest stage of maturity at which these grains could be swathed without loss of test weight or yield.Plots were cut daily over a period of several days using ke

On a fallow–wheat rotation on a loam soil in the Black soil zone of central Alberta, increased tillage over that required to control weeds had no effect on the yield of wheat. Four operations usually controlled weeds. Extra tillage had little or no

Tests conducted at Lacombe, Alberta, indicate barley may be harvested at a stage of maturity indicated by a kernel moisture content of 35 per cent, without any significant effect on malting quality. The per cent heavy grade and 1000-kernel weight inc

Main effects and interactions of nitrogen, barban (4-chloro-2-butynyl m-chlorocarbanilate) and time of seeding of wild oats (Avena fatua L.) in relation to barley were investigated in factorial growth chamber and field experiments. Culms and yield of
