EFFECT OF CULTIVATED ALLEYS ON YIELDS OF DIFFERENT POR¬ 
TIONS OF PLOTS IN VARIETY AND RATE OF SEEDING TESTS 
Examinations of the yield data as given in Table II for the rate of 
seeding tests with oats grown at Morris on sod land and under com¬ 
paratively dry conditions show that at each rate the outside border 
rows yielded very much higher (an average of 233.6 per cent) than the 
inside border rows, which in turn produced at a higher rate (an average 
of 139.7 per cent) than the central rows.

from the central 8 and 13 rows, respectively , which remained after the removal of 
border rows

At University Farm, under more favorable growing conditions, (he 
outside border rows yielded on an average 211.2 per cent of the yield 
of the central rows. The inside border rows more often yielded less 
rather than more than the average of the central rows. In the 64-pound 
rate, the abnormally low average is due to a chance combination of 
low-yielding rows in this particular rate of seeding. 
For the Work with the varieties at University Farm the data for the 
1917 work are included here in order that comparisons may be more 
easily made. In 1918 the outside border rows yielded considerably 
higher than the middle, inside, or central rows for all three crops. The 
middle and inside border rows of the oat and wheat crops yielded prac¬ 
tically equally, whereas for the barley crop there is a difference of 
approximately 5 bushels between the two yields. Both the middle and
