EXPERIMENTAL STATIONS — TUPtNIP CROP 1882. 



quantity of a more concentrated fodder. We thus see that the 

 quantity of solid matter per acre, although it is a much better 

 criterion of the value of a crop than the gross weight of bulbs 

 per acre, is still not everything ; the percentage of solids is an 

 important matter, and even a very little increase in that per- 

 centage is an advantage. 



The figures in these tables show us that manuring has some- 

 thing to do with quality in a turnip. Thus it is seen that at 

 both stations the parts manured in winter have produced a 

 slightly denser turnip than those manured in spring, and it can 

 be shown that this advantage is not got at a sacrifice of quantity. 

 A comparison of the first ten plots shows this very clearly. 



No V. — PUMPHERSTON. 



Undissolved Phosphates. 



At Pnmpherston, the winter-applied raw phosphates produced 

 on an average 14-8 tons per acre, while the summer-applied 

 phosphates produced 15*3 tons per acre. This is a surprising 

 result, but the surprise is diminished when the solids are con- 

 sidered. The winter-manured turnips are seen to be considerably 

 denser than the summer-manured ones, and the result is that 

 with less gross weight they nevertheless contain more solid 

 matter per acre. What the relative value of the solids in each 

 case is will be seen hereafter. It will be noticed that the 

 results at Harelaw are at variance with these. The differences 

 there are very trifling, but they are in an opposite direction.
