It is difficult to determine how f?,r the greening of the tuber 

 caused the above marked increase in crop, or to what extent 

 that increase has been brought about by the slight difference 

 in the length of the sprouts. 



It is proposed to continue the experiments. 



Manuring of Turnips. 

 The experiments on the manuring of turnips carried out in 

 1899 by the West of Scotland Agricultural College yielded 

 so. little information, owing to the season having proved very 

 unfavourable to the turnip crop, that they were repeated in 

 1900, and a report on them is published in Bulletin No. 9 of 

 that College. 



The experiments were especially designed to elicit informa- 

 tion on a number of minor problems in turnip manuring. 

 These included comparisons of the methods of applying nitrate 

 •of soda in moderate quantity, the relative advantage of 

 nitrate of soda and sulphate of ammonia as sources of 

 nitrogen, the relative efficacy of the three forms of potash 

 most commonly used (kainit or sulphate or muriate of potash), 

 and comparisons between basic slag and. superphosphate- 

 The investigations were carried on in the same manner on 

 thirteen farms in different parts of Scotland, there being 14 

 plots at each centre. 



The summer of 1900 was just as favourable to the turnips 

 as 1899 had been the reverse, and the crops were sufficiently 

 -heavy to give the manures opportunity of showing any dis-
