STALKS PER HILL 167 



22.4 bushels per acre. The amount of corn produced decreased with 

 the heavier rate of seeding in the dry year. 



The data from Iowa shows the effect of season, chmate and soil 

 on rate of seeding. Comparing the three zones of the state, namely, 

 northern, central and southern, it is seen that the yield varies with the 

 same rates of seeding. In the north, the heavier seeding produced the 

 higher yield. With a smaller ear, and lighter stalk more stalks can 

 succeed in a hill. Going south however to the larger ears, and heavier 

 stalks (and in some cases older soil) the number of stalks per hill must 

 be slightly reduced. In the southern part of the state it is generally 

 aimed to have from two to three stalks per hill, and in the northern 

 part of the state, from three to four. The average for the entire state 

 of Iowa shows the best results from three to four kernels planted per 

 hill. 



In these tests it should be added too that the yield of stover as a 

 rule was heavier with the thicker planting. In Nebraska the yield of 

 stover increased over 16 per cent between two and five stalks per 

 hill. The Ohio test shows a corresponding increase in yield of stover 

 amounting to 100 per cent, however, between the one stalk and 5 stalk 

 stand. This was for an average of ten years.
