All plots were overseeded with alfalfa
screenings
at planting time;
Predominant weed apecies were pigweed, velvet leaf,
venice mallow,
foxtail,
barnyardgrass,

Summary: (Crop Injury - stand reduction,
stunting,
chlorosis,
et c , )
Heavy rains after planting resulted
in plants emerging during three weeks.
A good stand was finally obtained,
but waterlogged
soil and nonuniform
emergence made it impossible to determine if plant stress resulted
from
chemical injury or growing conditions.
Summarx: (Crop Yield)
Plot yields appeared to respond well to weed control this year.
July and
early August were dry and some moisture stress
occurred, but their early
planting and early growth permitted the soybeans
established
to survive the dry weather and yield
20
to become sufficiently
relatively
