THE PROFITABLE AMOUNT OF SEED PER ACRE 



FOR CORN. 



W. H. Jordan. 



In 1894 an experiment was conducted for the purpose of testing 

 the influence of the rate of seeding upon the growth of corn, the 

 results being given in the Station Eeport for 1893, pp. 33-34. This 

 experiment has been repeated in 1895 and the results are given be- 

 low. 



As in 1894 one acre of land was used. This area received a 

 dressing of ten two-horse loads of stable manure and 750 pounds of 

 commercial fertilizer, the latter being made up of 500 pounds acid 

 phosphate, 100 pounds muriate of potash and 150 pounds nitrate of 

 soda. The acre was divided into twelve plots, or four sets of plots 

 with three plots in a set. 



On one plot in each set the single kernels were planted six inches 

 apart, on another nine inches, and on the third twelve inches. This 

 gave four plots or one-third of an acre planted by each method. 



Great pains were taken to insure a stand of stalks in accordance with 

 the plan, and the experiment appeared to be a success so far as the 

 field work was concerned. The intention was to allow the corn to 

 stand only until it began to glaze and then cut it and store it in 

 the silo. Owing to a necessary delay, the corn stood until it was too 

 ripe for the best results as a silage crop, and while this fact does 

 not affect the actual or comparative yield of dry matter, it accounts 

 for the loss per cent of water in the crop as harvested. Below may 

 be seen the composition of the corn for 1895 and the rates of yield 

 for both years.
