Experiments with Barley. 



The Midland Dairy Institute carried out some experiments* 



in 1903 with a view of ascertaining whether barley can be 



successfully grown on land in a reduced 



Manurial condition, after a white or other crop, by 

 Experiments c , . c - , T , 



With Barley means of artificial manures. In the plan 



of the trials there were ten plots, two 

 untreated and eight treated with dressings of nitrogen, phos- 

 phate, and potash. Each treated plot was given a dressing of 

 all three, and the effect of each was tested by increasing them in 

 definite proportions. Single acres of selected land in fairly 

 large fields were chosen for the trial grounds, so that each plot 

 was one-tenth of an acre, and the same experiment was carried 

 out on seven farms. In two cases, however, the results were 

 not considered satisfactory, and the particulars given below 

 represent the average results obtained from the five farms which 

 were situated in Lindsey, Lincolnshire. The soil on two of the 

 farms is described as light, on two medium, and on the remaining 

 one as heavy. The previous crops were in three cases barley, 

 in one case swedes carted off, and in one wheat. The barley 

 produced was valued at market prices according to quality, 

 varying in the case of good grain from 26s. 6d. to 30s. per 

 quarter of 442 lb. Light barley was priced at 70s. per ton and 

 the straw and chaff at 1 5s. per ton in every case. The cost 

 price of the manures were charged, but nothing was allowed for 

 their after effects. The results are summarised in the following
