On  the  lower  half  (bullock-feeding)  much  the  same  has  to 
be  recorded,  the  maize  meal  plot  (6),  however,  giving  the 
highest  yield. 
The  quality  of  the  corn  was  better  than  on  the  continuous 
wheat  plots,  the  grain  showing  more  strength  and  being  in 
good  condition.  The  differences  of  quality  were  not  marked 
as  between  the  different  plots. 
Rotation  III.  1910,  Swedes — after  Wheat. 
On  the  upper  half  (sheep-feeding)  1 cwt.  per  acre  of  basic 
superphosphate  and  1 cwt.  per  acre  of  sulphate  of  potash  were 
applied  to  each  of  the  four  plots  on  June  2,  1910,  swede  seed 
(“  Invicta  ”)  being  drilled  at  the  same  time.  A good  plant 
was  obtained  and  the  swedes  were  “singled  ” July  4-15.  The 
roots  grew  very  fairly,  though  there  were  blanks  here  and 
there. 
On  the  lower  half  (bullock-feeding)  farmyard  manure, 
previously  specially  made  in  the  feeding  boxes,  was  applied  to 
the  four  plots,  5,  6,  7 and  8,  at  the  rate  of  4 tons  per  acre, 
May  26-31.  That  for  plot  5 was  made  by  consuming  decorti- 
cated cotton  cake  with  roots  and  hay,  for  plot  6 by  consuming 
maize  meal,  and  that  for  plots  7 and  8 by  the  consumption  of 
roots  and  hay  alone.  Swede  seed  was  drilled,  as  on  the  upper 
half,  on  June  2,  no  mineral  manures  being,  however,  given. 
The  swede  crop  on  both  halves  was  pulled  December  9-17, 
and  the  roots  weighed.  The  results  are  given  in  Table  V.
