270 AGRICULTL'RK OF MAINK. 



Three plots of one acre each, planted to Irish Cobbler potatoes, 3 1-2 

 inches deep, treated uniformly in respect to phosphoric acid and potash. 

 Nitrogen fertilizers as follows : — 



Plot 6 A. 190 pounds nitrate of soda plus 425 pounds dried blood. 



Plot 6 B. 385 pounds cyanamide plus 190 pounds nitrate of soda. 



Plot 6 C. 580 pounds cyanamide. 



This experiment will be repeated in 1912. 



Potato Cultural Experiment. 



This is a continuation of the experiment started in 1910. comparing 

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

 ods. Three plots of land of one and one-eighth acres each are planted to 

 Irish Cobbler potatoes, treated with 1700 pounds of 4-8-7 chemical fer- 

 tilizer (1000 pounds in the hill, 700 pounds worked in). 



Plot 7 A. Planted 2" deep. To be highly ridged. 



Plot 7 B. Planted 5" deep. To receive level culture. 



Plot 7 C. Planted 3 1-2" deep. To have a low ridge. 



This experiment is planned to extend over 5 years. 



"^IixERAL Fertilizer" Experiment. 



A comparative test of the New England Mineral Fertilizer with barn- 

 yard manure and with complete chemical fertilizer, on corn and pota- 

 toes. New England Mineral Fertilizer does not carry soluble plant 

 food in any amount and is not at all similar to ordinary fertilizer. Six 

 one-twentieth acre plots, A, B, C, D, E, F, running in order from south 

 to north. 



Plot A. Corn, fertilized with 1-4 cord barnyard manure plus 25 

 pounds 4-8-7 chemical fertilizer. 



Plot B. Corn, treated with Mineral Fertilizer. 



Plot C. Corn, check — no fertilizer. 



Plot D. Potatoes, fertilized with 90 pounds 4-8-7 chemical fertilizer. 



Plot E. Potatoes, treated with Mineral Fertilizer. 



Plot F. Potatoes, check — no fertilizer. 



It is planned to repeat this experiment in 1912. 



Top Dressing on Grass. 



The second year of an experiment comparing acid phosphate and 

 Thomas slag as a source of phosphoric acid. Plots 11 A and 11 C each 

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

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

 phosphate. Plot 11 C has 600 pounds of Thomas phosphate powder. 

 Plot II B received no top dressing of any kind. 



This experiment will be continued one more season. 



EXPERIMENTS WITH THE APPLE, 1911. 



Experimental Nursery. 



About an acre has here been reserved for the growing of young apple 

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