NEW YORK AGRICULTURAL EXPERIMENT STATION. 161 
Why the gain was so much greater in the north test is not known 
The conditions in the two tests were practically the same except 
that in the north test the check rows were accidentally sprayed on 
July 3; but this would tend to lower the gain in the north test. 
Fortunately, the spraying was a light one owing to the spray pump 
being out of order and the pressure low. 
Combining the results obtained in the two tests we find that the 
average increase in yield due to spraying in this experiment was 
49 bu. 12 lbs. per acre. At 50 cents per bushel, which was the 
market price at the time of digging the test rows, this increase 
would be worth $24.60. Deducting $6.84, the expense of spraying, 
there remains a net profit of $17.76 per acre. ‘The actual selling 
price was 50 and 55 cents per bushel for about one-half the crop 
and 60 cents per bushel for the remainder.
