FIELD CROPS. 731 



Double (IrosRings of manure, amounting to 20 tons in 4 years, increased tlie 

 eroi)s witliout Increasinj: tlie net gains. It was found that conuneri-ial fertil- 

 izers, especially superpliosijliate, must be apjilied in excess. When potash was 

 excluded from the api»licali(>n. commercial fertilizers gave but small gains and 

 the good results secured where manure alone was used show that a moderate 

 dressing largely made up the potash deficiency of the light land. Sulphate of 

 ammonia had singularly exhausting effects on succeeding crops. 



Feeding off the swedes by sheep on this land apparently encouraged the finger- 

 and-toe disease, and this reduced the following swede crop. Linseed cake fed 

 to the animals when eating off the roots greatly increased the cereal crop imme- 

 diately following but influenced the second crop to only a small extent. 



IWork with field crops], I). A. Gilchrist (Couiifi/ yorthiunb., Ed. Com., Bui. 

 13, pp. J,2-6.3). — On an average for 3 years. Banner, Thousand Dollar, and 

 Sensation, all Canadian sorts, were the leading varieties of oats under test, the 

 yields being 65i, 62i, and Gl bu. per acre respectively. Payrent and Beseler 

 Prolific oats also gave good results. 



Chevalier barley grown at Cockle Park since 1903 gave considerably better 

 yields in 190S than either of the three Chevalier barleys the seeds of which had 

 been recently changed. Similar results were also secured with Goldthorpe 

 l)arley. 



In the wheat trials. Squarehead Master for 2 years gave the largest average 

 produce of both grain and straw with Scholey Squarehead ranking next. 



The results with beans are considerably in favor of the Scotch Horse beans 

 which were more vigorous and gave the heaviest crops of both grain and 

 straw. In a fertilizer test the Scotch Horse bean gave much heavier yields than 

 the Norfolk Tick beau, and the use of 6 cwt. of basic slag was more satisfac- 

 tory than the use of superphosphate. The application consisting of 10 tons of 

 manure, (5 cwt. of slag, and 1 cwt. of muriate of potash per acre gave the best 

 results, while the same application with the manure omitted ranked next in 

 efficiency. 



The clovers from English seed proved more vigorous and lasting at Cockle 

 Park than those from seed from abroad, and Italian rye grass from English 

 seed did better than that from French seed. 



On an average for 4 years. Mammoth Long Red mangel produced 21 tons and 

 19 cwt. of roots per acre as compared with 20 tons and 19* cwt. for Prize- 

 winner Yellow Globe. In 1908, 352 plants of Mammoth Long Red. lOS of Prize- 

 winner Yellow Globe, and 68 of Golden Tankard per acre produced seed the 

 first year. The results of fertilizer experiments indicated that nitrate of soda 

 had an advantage over sulphate of ammonia for mangels, that basic slag is 

 better tlian suiierphosi)hate, and sulphate of potash lietter than nuiriate of 

 l)otash. It was found profitable to apply a complete fertilizer together with 

 barnyard manure. The use of 2 cwt. of common salt per acre increased the 

 mangel crop by over 3J tons, but both lime and lime mud decreased the yield 

 of roots. Yields of swedes and turnips are also recorded and tlie percentages of 

 dry matter in swedes as shown in analyses of 4 varieties during the past 6 

 yeai's are given in a table.
