Maine; agricultural i:xperiment station. 1913. 267 



Plot 15 B. 3S5 pounds cyanamide plus 190 pounds nitrate of soda pei 

 jcre. 



Plot 15 C. 580 pounds cyanamide per acre. 



Potato Cultural Experiment. 



This is a continuation of the experiment started in igio, comparing 

 the results of planting at different depths with different cultural meth- 

 ods. Three plots of land are planted to Irish Cobbler potatoes, treated 

 with 1700 pounds of 4-8-7 chemical fertilizer (1000 pounds in the hill, 

 700 pounds worked in) per acre. 



Plot 19 A. Planted 2 inches deep. To be highly ridged. 



Plot 19 B. Planted 5 inches deep. To receive level culture. 



Plot 10 C. Planted 32 inches deep. To have a low ridge. 



"Mineral Fertilizer" Experiment. 



A comparative test of the New Mineral Fertilizer with barnyard 

 manure and with complete chemical fertilizer, on corn and potatoes was 

 made in 191 1. It was planned to repeat it in 1912. The results of 191 1 

 seem to be conclusive that this material is of no value on this land. 

 The experiment is cancelled. 



Top Dressing on Grass. 



The third year of an experiment comparhig acid phosphate ana 

 Thomas slag as a source of phosphoric acid. Plots 16 A and 16 C each 

 receive 112 pounds of muriate of potash and 100 pounds of nitrate of 

 soda. Plot 16 A has in addition 600 pounds of high grade soluble acid 

 phosphate. Plot 16 C has 600 pounds of Thomas phosphate powder. 

 Plot 16 B received no top dressing of any kind. 



Experiments With the Apple. 



Experimental Nursery, 



About an acre has been reserved for growing of young apple 

 trees to be used later in experimental plots. There are two thousand" 

 one-year-old French Crab seedlings for budding or grafting, and about 

 one thousand grafts of Tolman Sweet cions, root grafted on French 

 Crab, for experimental work. 



Fertilizer Experiment on Apple Trees. 



Thirty-two Baldwin trees have been divided into three sections. Ten 

 at each end have been treated with 4-8-7 chemical fertilizer at the rate 

 of 1000 pounds per acre plus nitrate of soda at the rate of lOO pounds 

 per acre. The 12 trees in the middle of the row have received the 4-8-7 

 chemical fertilizer at the rate of 1000 pounds per acre.
