“American Agriculturist” Prize Potato-Growing Contest, Yields from one measured acre. 
All records surpassed by the Mapes Potato Manure. “New secrets in Nature’s Laboratory.” 
The two largest crops of Potatoes ever grown with fertilizers or farm manure 
grown with the Mapes Potato Manure alone.* 
The following were the largest crops of potatoes grown in each State— 
and all these crops were grown exclusively with the Mapes Potato Manure: 
Maine, Aroostook County.745 bushels 
The largest crop ever grown in Maine. Second largest ever 
grown with fertilizers. 
Colorado .847 bushels 
“The largest crop ever grown with fertilizers or manure.” 
Massachusetts . 355 bushels 
Connecticut . 390 bushels 
The largest crops grown in Massachusetts and Connecticut 
in season 1889 (280 and 340 bushels) were also grown 
with the Mapes Potato Manure. 
Minnesota .•.325 bushels 
Idaho . 479 bushels 
The largest crops in each State grown with other fertilizers and farm 
manures, season 1890, were as follows: —595, 522, 500, 351, 325, 319 and 307 
bushels per acre. 
Summing Up the Potato Contest. 
In seventeen States in which the largest crop was grown with fertilizers, 
1889 and 1890, ten crops were grown exclusively with the Mapes Potato 
Manure; 847, 745, 669, 532, 479, 460, 428, 393 and 324 bushels per acre. 
Average yield per acre, 522 bushels. 
In the seven States in which the largest crop was grown with fertilizers 
other than the Mapes, the yields were as follows : 506, 454, 444, 401, 325, 319 
and 307 bushels per acre. 
Average yield per acre, 394 bushels. 
*Note: The only exception is the crop of 1,031 bushels grown on one acre last year (1889), also with THE MAPES POTATO MANURE, at Penn 
Yan, Yates Co., New York. This 1,031 bushel crop is the LARGEST EVER GROWN under any method. 
The American Agriculturist, February, 1890, page 58, in reporting this crop, says of the grower: “It seems that he did not notice 
our ruling against two crops or two plantings; therefore, while we were obliged to count only the yield of the first planting, which captured our 
second prize, Mr. Rose deserves full credit for the remarkable product of 1,031 bushels 19 1-2 pounds of potatoes on the contest acre. 
“As between Mapes Potato Manure and stable manure the past season,” says Alfred Rose, whose crop, 1,031 bushels per acre, 
won the Farm Journal prize, “there was a vast difference in favor of the former—more than half.” It is coming to be a well-recognized 
fact that a complete fertilizer, such as the. Mapes, gives surer results than stable manure in growing potatoes. This accords with our own 
experiments for the past four seasons. 
The two years’ Agriculturist contests have clearly demonstrated the superiority of fertilizers or chemical manures over stable manure 
for potatoes— The Farm Journal. 
The American Agriculturist, in commenting on these enormous 
yields with the Mapes Potato Manure, in comparison with other 
brands, stated: 
“Apparently it is not so much the QUANTITY, but the FORMS 
in which the plant-food is furnished that govern yield, provided a 
reasonable amount is supplied.” 
“Under average conditions, and in far the greater number of 
cases, we do not hesitate to name the Mapes Potato Manure as the 
best and most profitable fertilizer for potatoes.”— American Agri¬ 
culturist. 
TFIE MAPES POTATO MANURE.—“Its action approaches 
certainty, or as near to it as any manure can be expected to do.”— 
E. S. Carman, Rural Nezv-Y orker. 
“The Mapes Manures give surprising results, and we believe the 
reason is, that the ingredients are mixed with brains.”— Wilmer 
Atkinson, Farm Journal. 
“Our own experience with various commercial fertilizers has 
convinced us that with judicious use of the Mapes Manures worn 
out lands can be restored to fertility quicker, and with less expense, 
than in any other way.”— American Agriculturist, 
The Great Corn Contest of the American Agriculturist 
(45 CROPS IN ALL) 
Crops 213, 119, and 95 bushels each; grown on one measured acre exclusively with the Mapes Corn Manure. 
Extract from the American Agriculturist, Jan. 27 , 1906 , page 96 , The World's Record Corn Crop. Please give the largest authentic 
yield of corn for one acre of ground, variety, etc., etc. Dr. W. L. Davenport, Washington County, Virginia. 
The largest corn crop yet recorded was grown by Capt. Z. J. Drake of Marlboro County, S. C. Not only is this the largest 
grown in America but£ in the World. In one season and on a single acre he produced 255 bushels and thus secured the American 
Agriculturist’s prize of $ 500 . This was an elaborate experiment to prove how much corn could be actually grown on an acre, the 
cost of production having been a secondary matter in this case. 
The second prize of this contest was won bv Alfred Rose of Yates County, N. Y., who produced 213 bushels of Early Mastodon 
corn. He planted one kernel every foot in rows 3 feet apart and fertilized with 800 pounds Mapes Corn Manure. I he soil was a sandy 
loam. The third prize was awarded to George Gartner of Pawnee County, Neb., who raised 171 bushels of Early Mastodon on a 
black, rich loam, fertilized with 90 loads of barnyard manure, planted in hills 3 by 3 feet. 
Full details of all the crops, soil, planting, fertilizer, etc., given in “THE BOOK ON CORN,” Orange Judd Co., New York, Chicago, 1903. 
WHEAT. 
The only Prize Wheat Crop grown with fertilizers in the American Agriculturist Prize Crop Contest, 1889, was raised by Mr. 
Bartholomew Gedney, Westchester County, N. Y., with 600 lbs. of the Mapes Complete (wheat) Manure applied broadcast and harrowed in. 
Variety: White Beardless. Harvested July 2 , 1889. Yield, 46 bushels on one acre. Straw, 6,347 lbs. Grain, 2,750 lbs. One even or 
struck bushel weighed 60 lbs. Dimensions of contest acre, 290 4-10x150 feet. Entire cost, $38.50. 
The other prize wheat crops were raised in Utah and the West. 
OA 
133 bushels per acre. Variety: “White Beardless,” grown with 800 lbs. of the Mapes Manure, New York, Yates County. 
“Fertilizer Farming Up to Date.” 
The Poorest Light, Sandy Soils Brought Up to High Fertility with Profit from 
the Start. A review of practical experience covering 20 to 25 years on varied 
soils (from almost pure sand to medium heavy loam) without stable manure (only the Mapes Complete Manures used), with PROFIT FROM THE START, and the 
lands found to be steadily improving in fertility and yielding increased profits. These farmers and special crop growers are among the most successful in the 
country. (Mailed free).
