204 The Woburn Field Experiments , 1904. 
early in May, 1904, and the potatoes were “ set ” on May 12, the 
artificial manures, as given in Table IX., page 203, being 
placed in the drills at the same time. The crop was lifted on 
September 13, and the tubers sorted and weighed as set out in 
Table IX. 
It will be seen that in each case better results were 
obtained with sulphate of potash than with kainit. The 
amounts of potash supplied by the two dressings were, it may be 
said, just about equal. As between sulphate of ammonia and 
nitrate of soda there was little to choose, slightly the highest 
crop of all and the largest amount of ware or saleable potatoes 
being obtained from using sulphate of ammonia together with 
sulphate of potash, though, when kainit was employed, nitrate 
of soda gave a larger crop than did sulphate of ammonia. 
“Finger-and-Toe” in Turnips ( Great Hill ), 1904. 
Tlie‘ series of experiments on this subject, begun in 1900, 
was carried a stage further, and on the same piece of land as 
before, the treatment being the same as in 1903. All the 
applications were made on December 22-26, 1903, with the 
exception of the lime on plot 6, and the plots were then 
ploughed and left for the winter. On May 23, 1904, dung was 
carted out and spread at the rate of 15 tons per acre, being 
subsequently ploughed in. “ Monarch purple-top ” swede seed, 
at the rate of 4 lb. per acre, was drilled in on May 26, and on 
plot 6 lime was put in with the seed. There was a fair crop 
all over with the exception of plot 3 (no treatment), and the 
roots were pulled and weighed on October 13-15. The results 
are given in Table X., below.
