Nutgrass in four randOlllon'!'_~!J?9-t..square areafl.2!l.plot wlls~ounted on June 19 indicating a range of 1000 to 6000 plants per plot.

The pigweed grew as rapidly and as tall as the ceen, The corn was harvested on August 15 at the' fUll pollen-shed stage in order to prevent further development of weeds. As seen as weed estimates were made, the area was plowed. Because of the tangle of n.ut,grllS.Sand crabgUIlS.J it did not seem feUible to try to count every nutgrass pl:ant' on each of the 72 plots. <strong>Weed</strong> estimates were made by cutting nutgrass, crabgrass and pigweed;.at ground level frOlll:lIt1 area 3 feet wide (1.5 feet on either side a corn row) and 7 feet long. These weeds were separated by genera and the grams of oven-dry weights per sample area are presented in table 2. Analysis of varianee of the oven-dry weights showed that the 602A corn produced significantly more yield than the dwarf corn. The average yield for all treatments'was 3.01T/A of Penn. 602A and 2.72 rIA of Penn. 602 dwarf. .1'he analysis ,~owed there was no significant interaeUon between treatlnente and varieties u>!.r as dry matter' wasconcerned. Therefore only the average dry weight f,or t;he;.,2 varieties is shown in table 2. It
