372 EXPERIMENTAL STATIONS — EEPORT FOPt 1880. 



It is evident from tlie above table that there is no difference 

 in the percentage of albuminoid matter and non-nitrogenous food 

 material in the turnips grown with dissolved and undissolved 

 manures. There is a considerable increase of those two con- 

 stituents per acre, but it is quite proportionate to. the increase of 

 the total crop in each case. 



To sum up the results of these small experiments as to phos- 

 phates, it has been shown that dissolved phosphates have increased 

 the crop of turnips on our two stations of Harelaw and Pumpher- 

 ston 15 and 25 per cent, respectively, and that the increase has 

 not been due to a disproportionate amount of water, woody fibre, 

 ash, or other worthless constituent, but that it is due to a normal 

 increase in all the constituents of the crop ; that is to say, the 

 quantity of the crop has been increased, but its quality has 

 remained almost unaffected. 



EXPERIMENTS ON THE ^lARQUIS OF TWEEDDALE's HOME FARM OF 



YESTERMAINS. 



Turnip Crop, 1880. 



A very interesting and well conducted series of experiments 

 was made this year by the Marquis of Tweeddale upon the Home 

 Farm of Yestermains. There were six experiments, and these 

 were duplicates of plots 3 and 4, 5 and 6, 9 and 10 of the Society's 

 scheme, that is to say, coprolites, bones, and Canadian apatite, 

 both in the undissolved and dissolved forms. The field selected 

 for the experiments was well adapted for the purpose, and the 

 experimental plots were situated in the middle of the field run- 

 ning from end to end, a distance of about 300 yards, and each 

 plot covered half an acre. The appearances presented by the 

 plots during the whole season were very striking, and the follow- 

 ing table supplied to me by Mr Swinton, under whose super- 

 intendence the experiments were conducted, shows the details of 

 the manuring and cropping at a glance.
