FIELD CROPS. 235 



the highest profit was secured after au application of 60 lbs. of sulphate of 

 potash, while losses followed the use of superphosphate, muriate of potash, 

 basic slag, nitrate of soda, or sulphate of potash in varying amounts and 

 combinations. 



In manorial experiments with Algerian oats profits of more than £13 5s. 

 arose from applications of 1 cwt. each of superphosphate, basic slag, and bone 

 dust in different combinations. First grade seed oats produced 75 bu. per acre 

 and second grade 68 bu. Among 8 varieties of rust-resistant oats the Garten 

 produced the most valuable crop. Mangels following sorghum and millet pro- 

 duced the highest profit apparently due to manures, when fertilized with 2 cwt. 

 superphosphate and 2 cwt. basic slag per acre. Notes are given on sowings of 

 sugar beets, carrots, turnips, rape and kale, and various fodder crops. 



At the Moumahaki Farm, variety tests of wheat, barley, and oats are reported. 

 Only the Algerian oat proved rust resistant. On pasture land, an application 

 of nearly 2 cwt. of steamed bone dust was followed by a greater increase in 

 profit than applications of other sources of phosphorus or of ground lime or 

 Maiden Island guano. Notes are given on the manuring and rate and method 

 of planting of pumpkins, maize, sorghum, millet, cabbage, kohl-rabi, and carrots. 

 Among fodder crops. Golden Beauty maize produced 35 tons per acre, Sinclair 

 Champion carrot 28 tons of tops and OJ cwt. of roots, and Sutton Eclipse Drum- 

 head cabbage 40 tons, 14^ cwt. of feed. 



In a test of 11 different applications of fertilizers to rape, the highest but 

 least economical increase of yield was secured from the use of 2 cwt. of basic 

 superphosphate. Cross dressings of nitrate of soda, sulphate of ammonia, and 

 cyanamid produced no apparent improvement of the crop. On swamp land, 

 an application of 24 cwt. of superphosphate produced an apparent increase in 

 yield of over 20 tons of rape at a cost of 144 cts. per ton of increase. 



An application of 4 cwt. of superphosphate was followed by a greater increase 

 in yield of potatoes than the same application in addition to 1 cwt. of muriate 

 of potash. 



Vilmorin Improved sugar beets and Sutton Mammoth Long Red mangels 

 produced the maximum yields of sugar and dry matter per acre respectively, 

 while the most economical increase in yield of mangels after fertilizers was 

 secured by the application of 44 cwt. of superphosphate and 1 cwt. of gypsum. 

 An absolute decrease in yield of 5 tons 94 cwt. followed the application of 44 

 cwt. of steamed bone dust and 1 cwt. of cyanamid. 



Garton Superlative swedes produced the maximum yield of total dry matter 

 per acre and the highest yield of roots and tops per acre and had only a trace 

 affected by club root among 17 varieties so affected. The most economical in- 

 crease in yield of turnips followed the application of IJ cwt. of superphosphate 

 and li cwt. Maiden Island guano, in a test of 25 different formulas. Notes 

 are given on the application of lime with fertilizers, the turnip fly, on the 

 breeding of oats, wheat, barley, and alfalfa, and on sowings of more than 75 

 different grasses and legumes. 



At the Weraroa Farm, the Great Dakota oat produced the maximum yield 

 of 60 bu. per acre. Four acres of Azov barley gave an average yield of 60 bu. 

 per acre and the Clarence Wonder produced the maximum estimated weight of 

 corn among 5 varieties of field corn, ranging from 50 to 75 tons per acre, 

 while the Broad Yellow sweet corn produced an estimated yield of 70 tons per 

 acre. Among 86 varieties of potatoes, the Up-to-date produced the maximum 

 yield of 14 tons 2J cwt. per acre.
