The Woburn Field Experiments , 1913. 401 
The barley was “ Chevalier ” and was sown on March 
14, 1913. 
The crop was cut on September 8, and the harvest results 
are given in Table VII.

The highest result was obtained from the thickest seeding, 
though the difference between the highest and lowest rate of 
seeding was only bushels of corn per acre. Also the greatest 
amount of straw was obtained with the thinnest seeding. 
The valuer’s remarks were that the barley was only just 
useful for the year and a great deal below the average of fine 
barleys. On a basis of 32s. per quarter, the highest value, 29s., 
was given to plot 1 (the thickest seeding), the others being 
classed alike at Is. per quarter less. 
Nitrogenous Top-Dressings on Wheat. 
Wheat being grown over a considerable portion of Warren 
Field, it was determined to try in 1913 further experiments 
upon the influence of different nitrogenous top-dressings. 
Nitrate of ammonia, a newly introduced fertiliser, was tried 
in comparison with sulphate of ammonia and nitrate of soda. 
The wheat (“Red Standard”) was drilled November 4-6, 
1912, at the rate of 10 pecks per acre. On May 28, 1913, the 
nitrogenous top-dressings were applied, these being given in 
quantity such as to supply 30 lb. of ammonia per acre. The 
actual weights per acre so applied were as follows : — 
Sulphate of ammonia . . .119 1b. 
Nitrate of soda . . . . 153 ,, 
Nitrate of ammonia . . . 70 f 6 lb. 
The crop was cut on August 11, and the harvest results are 
given in Table VIII.
