| dc.description | Numerous experiments were conducted to determine the effect
of spacing upon plant development and yield of small grains and other cropss. Most of this work was conducted by varying the rate of seeding in the row or by thinning the plants in the row. These studies demonstrated that tillering changes were sensitive to variation in spacing,
while yields were determined largely by soil fertility, weather conditions, absence or presence of weeds, diseases and pests. This article discusses a study conducted to determine the effect of sowing small grains in six and seven inch drill spacing on yield of grain and straw,
test weight of grain, the number and growth of weeds as reflected in two rates of seeding. These tests were conducted in 1948 and 1949. Data presented supported previous observations that changing the spacing of drilled rows of grain from six to
seven inches could be done without altering the yields of grain and straw. | |
