540 Summary of Agricultural Experiments, [oct., 



■compound manure, and is. $d. per ton for home-made mixtures. In 

 1907 the comparison was based on money value, a similar sum being spent 

 on both. The home-made mixture gave three tons of roots more than the 

 purchased manure. 



Manuring of Swedes {Cumb. a?td Westmorld. Farm School, nth Report, 

 1907). — Four plots were treated at Newton Rigg with various artificials 

 costing 29J. per acre in each case. The best result was obtained from 

 •4| cwts. kainit and 6f cwts. of basic slag. Three plots were treated with eight 

 .loads of dung with various artificials, and i cwt. nitrate of soda, 1 cwt. 

 kainit, and 3 cwts. superphosphate gave the best result. 



Manuring of Swedes {Midland Agric. Coll., Bull. 5). — Six trials are 

 reported with farmyard manure and various combinations of artificial 

 manures. There was very little difference in the profit per acre from 15 tons 

 or 10 tons of farmyard manure or 10 tons of farmyard manure with a small 

 dressing of artificials, and after charging 3s. 6d. per ton for dung the value of 

 the increase over the unmanured plot was insignificant. The best result 

 was obtained from a dressing of 191 lb. nitrate of soda, 233 lb. super- 

 phosphate, and 62 lb. sulphate of potash per acre. 



Manuring of Swedes { Univ. Coll. Reading, Results ofExpts., 1907). — Sixteen 

 plots of one-eighth of an acre each were laid out to show the effects of 

 different manurial treatment. Another plot was used to compare a bought 

 manure with home-mixed manure (1) having the same analytical composition, 

 and (2) costing the same sum. The commercial manure costing £6 10s. per 

 ton gave slightly less return than an ordinary mixture costing £3 per ton. 



Manuring of Swedes {Armstrong College, Newcastle, Bull. No. 5, 1907). — 

 Experiments on the manuring of swedes were conducted at five centres in 

 Durham during 1906, but the crops at two centres were not satisfactory. At 

 ■the remaining centres the results varied, and it is not considered advisable 

 to draw conclusions from them as to the most suitable dressing of artificials 

 .to be used with dung. 



Manuring of Swedes {Univ. Coll. of N. Wales, Bangor, Bull. VIII. 

 1907). — An experiment was arranged to compare the effects of calcium 

 • cyanamide with nitrate of soda and sulphate of ammonia as a manure for 

 swedes. Four plots received superphosphate and kainit at the rate of 

 392 lb. per acre each, and three plots received in addition 133 lb. cyana- 

 mide, 84 lb. sulphate of ammonia and 112 lb. nitrate of soda respectively. 

 The plot receiving superphosphate and kainit alone gave a somewhat better 

 ■result than the plots receiving nitrogen. 



Manuring of Swedes {Beds. C. C. Report on Demonstration Plots, 1907). 

 — Eleven plots were tested with different combinations of fertilisers. The 

 •complete dressings produced the heaviest crops, but were not the most 

 profitable when the cost of the manure was deducted. The largest increase 

 at the lowest cost was obtained from \ cwt. sulphate of ammonia and 3 cwts. 

 superphosphate. 



Varieties of Swedes {Beds. C. C- Rept. on Demo?istration Plots, 1907). — 

 .Seven varieties were tested, but there was very little difference in the yield 

 -of the five varieties of the purple top type. Two bronze top varieties gave 

 decidedly lower yields. 



Varieties of Swedes {Field Expts., Harper-Ada?ns Coll., 1907). — Trials
