338 EXPERIMENT STATION RECORD. 



Potatoes. — Forty varieties were tested in 1899, and 12 of these had been grown the 

 previous year. Sixteen of the 40 kinds grown in 1899 Avere planted for trial in 1900. 

 The varieties giving the best average yields for the last 2 seasons were Early Dawn, 

 Thoroughbred, Early Ohio, Burpee Sujierior, Six "Weeks, Freeman, Secretary 

 Wilson, Early Andes, and Carman No. 1. Early Ohio, Early Dawn, and Early 

 Andes are recommended as good early potatoes. The results of experiments on the 

 thickness of planting showed a general decrease in yield as the distance between the 

 hills increased. The seed in this case had been cut from 2 to 3 eyes to the piece 

 and planted about 4 in. deep. Doubling the quantity of seed per hill decreased the 

 yield and proved detrimental to the quality of the tubers. Planting potatoes from 3 

 to 5 in. deep gave the largest yields but a jjoorer quality of tubers than deeper plant- 

 ing. Shallow and flat cultivation gave larger yields than deep cultivation and 

 hilling. 



Report of the experimentalist, C. A. Zavitz ( Ontario Agr. Col. and Expt. Farm 

 Rpt. 1900, p2). 96-125, figs. 5). — The work here presented consists largely of variety 

 tests, and is in continuation of experiments conducted in previous years (E. S. R., 12, 

 p. 328). Other work of the experimental department is l>riefly noted. The results 

 of 10 jears' experiments show that Joanette Black oats gave the largest average yield 

 of all varieties tested. Sixty-seven varieties were grown this season, and among 

 them Probsteier, White Siberian, Mennonite, Daubeney, Waterloo, and New Electric, 

 in the order given, produced the largest yields. Vanhouten, Scottish Chief, and 

 Black Irish were the least productive varieties in the test, giving less than one-half 

 the yield of the best yielding sorts. The grain per measured bushel of Whiteside, 

 Early Dawson, Mortgage Lifter, White Dutch, White Superior Scotch, and Washing- 

 ton weighed over 40 lbs., but it was observed that varieties producing heavy grain 

 are usually only moderate yielders, and that the grain is generally thick in tlie hull. 

 The earliest varieties, Alaska, Daubeney, and Black Mesdag ripened about the 25th of 

 July. Seed of 6 different varieties grown in Missouri, but originally from the 

 Ontario Agricultural College, was compared with seed grown at the college, and the 

 results of this single test showed that the Missouri seed produced the largest yields 

 and the Ontario seed the heaviest grain. 



The experiments with barley show that the 6-rowed varieties have given much 

 better results than the 2-rowed varieties. INIanshury barley has been compared with 

 the widely cultivated Common 6-rowed barley for 12 years, and the results show 

 an average yield of 66.8 bu. of grain and 1.9 tons of straw per acre for the Manshury 

 and 57.9 bu. of grain and 1.6 tons of straw for the Common 6-rowed. The average 

 weight per bushel of Common 6-rowed was 52.7 lbs., or 1.6 lbs. greater than the 

 weight of the Manshury. Of the 19 varieties tested this season, California Brewing, 

 Four-Rowed Canadian, and Six-Rowed Baxter Improved gave the best yields. 

 The heaviest grain weighed 54.6 lbs. per bushel and was produced by the Oder- 

 brucker variety. The average results for several years show that the best 2-rowed 

 barley yielded about 14 bu. per acre less than the best 6-rowed variety. The 

 2-rowed varieties giving the best average yields for a period of several successive 

 years were New Zealand, Chevalier, Gold Foil Hansford, French Chevalier, 

 Empress, Two-Rowed Canadian, and Kinna Kulla. Of the varieties tested in 1900 

 Two-Rowed Canadian, Duckbill, A'ermont Champion, and Jaramn Selected Beardless 

 produced the highest yields. 



Of 12 varieties of hulless barley grown this year Guy Mayle and Black Hulless 

 were the best grain producers. Purple and Black Hulless yielded the heaviest grain, 

 the weight per measured bushel being 64 and 62| lbs., respectively. Hulless barley 

 usually weighs about 60 lbs. per bu. 



Twenty-eight varieties of spring wheat were tested this season, and among them 

 Red Fern, Bart Tremenia, Pringle Champion, and Wild Goose, in the order men- 

 tioned, gave best returns. Harrison Bearded, Bart Tremenia, Wild Goose, Konis-
