12 <br /> one if it is a single stem, while a bunch grass is necess- <br /> arily counted as one plant. The bunch grasses have an <br /> advantage in that they are more easily seen and are less <br /> likely to escape being counted than small single stems . <br /> The results indicate a successful seeding has <br /> resulted on the 1985 and 1986 areas . The Great Plains <br /> Agricultural Council (1966) considered a stand was successful <br /> if at least one plant per square foot became established. <br /> 4 . 3 Production <br /> Total annual yields in 1988 were surprisingly close <br /> tetween the 1985 and 1986 areas studied (Table 6) . When <br /> annual weeds are subtracted, however, the areas change <br /> considerably. the ' 86 RA had 476 pounds per acre compared <br /> to the 1500 pounds in the ' 85 RA. <br /> 4 . 4 Air Dry Weights <br /> Determining weights in grams in the field at <br /> the time the samples were clippd and drying them for air <br /> dry weights , provided the opportunity to calculate the per <br /> cent moisture content of the plants (Table 7) . <br /> An expected outcome of this calculation is the <br /> order the cool season, warm season and weedy species ranked <br /> in relation to their moisture contents . The Smooth <br /> brome and wheatgrasses had the lowest moisture content. <br /> At the time of sampling these plants appeared "cured" out as <br /> in hay or straw. Newt highest were the warm season species <br />
