appears to be much the same as that of wheat. (121) In fact, 



so far as the cereals are concerned, the influence of the several 

 ingredients of commercial fertilizers appears to be more depend- 

 ent upon the soil than upon the crop. The following table gives 

 the average yield of maize cut green for silage during fourteen 

 years at Ottawa, Canada, when grown continuously on the same 

 plats : ^ 



Fertilizers applied each year from 1888 to 1898 or 1899. No fertilizer used 

 since. Clover sown in 1900 in place of maize and plowed under in May before 

 maize was planted. 



290. Methods of Applying Fertilizers. — ^While commercial 

 fertilizers may be applied broadcast, this method is not generally 

 advisable. Some maize planters have fertilizer attachments 

 which apply the fertilizer with the seed. Where a wheat drill is 

 used for drilling maize, it is a common practice to drill the fer- 

 tilizer through the hoes on each side of the hoes drilling the 

 maize, thus placing the fertilizer in the soil seven inches on 

 each side of the maize row. (305) 



291. Influence of Season on Efficiency of Fertilizers. — At the 

 Illinois Station where maize was raised continuously for twenty 

 years on manured and unmanured plats (284) in certain seasons 

 of deficient rainfall the unmanured plat gave greater yield than 

 that receiving annually stable manure. At the Indiana Station^ 

 both stable manure and commercial fertilizers used continuously 

 for five years gave the best yields during seasons of high rainfall
