PBEPABATION AND PLANTING

YIELD OF FORAGE 



129. When yield of forage is considered, numerous 

 experiments have shown that the yield of forage increases 

 with the rate of planting up to a point about twice that 

 required for maximum yield of grain. The following 

 data illustrate : —

EFFECT ON COMPOSITION 



130. The principal effect on composition when the rate 

 of planting is increased is the change in ratio between 

 percentage of ear and stalk. By referring to Table XLVI, 

 last column, it will be seen that the proportion of stalk to 

 ear increases as the rate of planting increases, there being 

 more than twice the proportion of stover with the thickest 

 planting as compared with the minimum ratio (11,880 

 kernels). The comparative analysis of stover and grain 

 as summarized by Jenkins and Winton is given in the 

 following table : —
