Summary of Manurial Experiments. 



Average Yield. 



Note. — Superphosphate was applied with the seed of the green manure crop in 1909. 

 Superphosphate was applied for the green manure crop. 



In 1910 and 1911, no 



Although no general conclusions can be drawn at this stage of the experiment, it may be 

 noted that the percentage of Bitter Pit in each plot is comparatively small, the highest being 

 3 per cent., and the lowest only about \ per cent. It is also noteworthy that the plots with the 

 highest and the lowest percentage were treated exactly alike as regards manuring, not only in. 

 1911, but in the two preceding years.
