Experiments with Swedes. 



[JULY, 



obtained is not what might have been expected." In this 

 connection it is interesting to notice that Plot 12, which was 

 dressed with a manure containing the equivalent by analysis of 

 a compound manure, gave a greater yield than either Plots 3 or 4 ; 

 this manure, it will be seen, contained less potash and rather 

 more nitrogen than Plot 4. Plot 5, which received a heavy 

 dressing, gave a good result. The yield obtained is more than 

 double the crop of the unmanured plots, and is the heaviest of 

 any of the plots. The profit is not quite so much as on Plot 3, 

 but if the condition in which the land is left is taken into 

 consideration, preference must be given to the heavier dressing. 



Tests were also made on five plots at five farms with a view 

 of ascertaining what was the best artificial dressing to use with 

 10' tons of farmyard manure, and also whether a combination of 

 this sort was to be preferred to a heavier dressing of 1 5 tons 

 of dung.

* Loss. 



The additional five loads of farmyard manure used on Plot 6 

 compared with Plot 7 only produced an extra ton of swedes, 

 while the fertilisers applied on Plots 8, 9, and 10 resulted in an 

 increase, compared with Plot 7, of 2 to 4I tons. On Plot 10, 

 however, as on Plot 4, the addition of kainit had an injurious 

 effect, and considerably reduced the yield. In regard, to this, 

 it is observed in the report that " Although such a result as this 

 is not so entirely unexpected when kainit is used in addition to 

 farmyard manure, still it is more the exception than the rule ; 

 in fact, in an ordinary season, kainit would probably have had 

 a beneficial effect." 



Comparing these plots, however, with those which received
