The Bulletin. 7 



Three hundred pounds of a mixture of acid phosphate, dried 

 blopd and manure salt/ which contained 1 per cent available phos- 

 phoric acid, 11/^ per cent potash and 3 per cent nitrogen (equal to 

 3.64 per cent ammonia), costing $3.24, were used. 



The slight ridges formed in covering the fertilizer were opened 

 and the corn planted a little below the level, all tests of the same kind 

 at the same farm being given the same treatment as to time of plant- 

 ing and otherwise. All cultivations were as nearly level as possible 

 and rather deep early in the season, with the small hoes of the Planet 

 Jr. Cultivator, but became shallower, using the large hoes as the sea- 

 son advanced and the roots extended towards the middle of the rows 

 and nearer the surface. This system of cultivation afforded pretty 

 thorough breaking of the land early in the season and prevented the 

 disturbance of the root systems of the plants later. An effort was 

 made to cultivate every ten or twelve days, as far as the weather would 

 permit, and especially immediately after rains, in order to produce 

 a fine dust mulch with the shallow running .plows, to retard the 

 evaporation of the recently-added moisture. 



The varieties of corn were harvested and shocked on September 5 

 at the Edgecombe farm, on September 3 at the Iredell farm, on 

 August 17 to September 6 at the Experiment Station farm, and on 

 September 11 to October 10 at the Transylvania farm, as each variety 

 matured; but were not husked until ISTovember 21 and 22 at Edge- 

 combe, ISTovember 2 at Iredell, October 3 and 4 at Experiment Sta- 

 tion, and in ITovember at Transylvania. 



RESULTS OF VAEIETY TESTS OF CORN. 



The results of these tests are contained in the following tables : 



^ Manure salt is a potash compound, containing about 20 per cent of potash, principally in the 

 form of muriate.
