111 general, the results of the tests made in 1914 agree with those 
obtained the previous year. For instance, in the 5-inch planting the 
tillers per plant in 1913 averaged 2.6, whereas in 1914 the average

thinned plat in 1913. This was un- 
doubtedly due to the seasonal condi- 
tions. The weather during April and 
May, 1914, was unusually wet and 
cloudy, during April especially so, 
while in 1913 the conditions were 
more nearly normal. Temperature

columns denote the yield in bushels, while the 
tillers are represented by diagonally shaded 
columns and the branches by dotted columns. 
and sunlight, it appears, have a very marked effect on the number of 
tillers that are produced. 
Another point brought out in the test of 1914, which was not notice- 
able the preceding year, was the branching of the plants, which 
took place after the warm weather set in. Counts were made of 
all the different plats at the time of ripening, and the number of 
branches averaged as high as 3.44 where the plants were spaced 24 
inches apart. From this the number of branches decreased uni- 
formly until there were only 0.31 per plant in the unthinned rows. 
It is probable that, as tillering did not take place until the plants 
were well along in growth and as there was an abundance of moisture 
in the soil, the plants spaced to a greater distance than 5 inches offset 
this wide spacing by sending out branches.
