928 EXPERIMENT STATION RECORD. 



2.(58 bu., and .*>(»() llts. of cottuii-seed meal per acre by 1.79 bu. The largest 

 increase, 31.98 bu. per acre, from different fertilizer applications for corn after 

 winter wheat was secured from 300 lbs. per acre of cotton-seed meal. 



The Japanese, Extra Early Black, Medium Green, and Ito San Yellow soy 

 beans ripened September 1, 1, 15, and 3(), and yielded 14.1G bu., 10.00 bu., 20.83 

 bu., and 22..50 bu. per acre, respectively. The Wbii)poorwill cowpea has given the 

 best general results at the station. Five varieties of Canada field peas were all 

 failures. Of 20 varieties of potatoes the 5 leading in yield were as follows : 

 Burbank 230, Early Rose 227, Beauty of Hebron 224, (ireen ^lountain 201, and 

 (iold Coin 197 bu. per acre. 



Field experiments in Staffordshire and Shropshire and at the Harper 

 Adams Agricultural College, (i. Balfour and .1. C. Rushton (Harper-Adams 

 A(ir. Col. Joint Jipt., 1006, pp. .'/J, /)/.s-. 2. ih/in. 1). — At the college the experiments 

 in manuring meadow land, in progress since 1903, have shown that the use 

 per acre of 10 tons of barnyard manure, together with an application of 1* 

 cwt. of nitrate of soda, 2* cwt. of superphosphate, and i cwt. of sulphate of 

 potash, gave the heaviest crop of all combinations tested, but that the use per 

 acre of 2J cwt. of superiihosphate and i cwt. of sulphate of potash was the most 

 profitable practice. The barnyard manure remained perceptibly effective for 

 aliout 4 years. Super] ihosphate gave the most marked results, either alone or 

 in coml»inati()n. 



Of 8 varieties of English and American wheats. Borwick (irey Chaff, Square 

 Head Master, and Manitoba No. 1 led in productiveness, with yields of 50, 49, 

 and 48 bu. per acre, respectively. Clnb wheat stood first in value for milling 

 purposes, but gave the lowest yield, only 22 bu. per acre. Borwick Grey Chaff 

 was poorest in milling quality. Of 5 varieties of barley, Carter Prolific ranked 

 first in yield, with 40 bu. per acre, and also stood first in malting quality. 

 Waverly, the best yielding of 9 varieties of oats, produced 71 bu. per acre, being 

 followed by Garton Abundance, Thousand Dollar, and Highlander, producing 

 69, 60, and 03 bu. per acre, respectively. Thousand Dollar, Highlander, and 

 Garton Abundance produced good, short, plump grains. The grain of Waverly, 

 Wide Awake, Mounted I'olice, and Beslar Giant is considered too long and thin. 



Commercial fertilizers applied with barnyard manure largely increased the 

 average yield of mangels for 3 years. The use of 4 cwt. per acre of salt and of 

 4 cwt. of kainit, or J cwt. of sulphate of potash, had a very marked beneficial 

 effect on the crop in 190(). Dickson and Robinson Perfection, Sutton Prizewinner 

 Yellow Globe, and Leightou Intermediate led in yield with 48 tons 15 cwt, 

 41 tons 7 cwt., and 39 tons 8 cwt. per acre, respectively. The largest yields of 30 

 varieties of swedes were obtained from Drummond Imperial and Carter In- 

 victa. Ground lime at the rate of 10 cwt. per acre was more effective in rednc- 

 i-^g finger-and-toe disease than basic slag at the rate of 5 cwt. 



The results of experiments in Shropshire were in favor of planting potatoes 

 in rows 27 in. apart, of the use of immature Scotch and Irish seed potatoes, and 

 of the boxing or sprouting of seed potatoes in boxes before planting. The 

 largest total yields for the last 3 years were ]irodnced by Conquering Hero, 

 Snowdrop, and Leda. Ccaitinued propagation from cuttings indicated a loss 

 of vigor. The most expensive fertilization was the use of 20 tons of barnyard 

 manure, and the most economical the use of If cwt. of sulphate of annnonia, 4J 

 cwt. of superpbosi»hate, and li cwt. of sulphate of ijotash per acre. A complete 

 application of commercial fertilizers with 15 tons of barnyard manure per acre 

 gave this season a better yield of mangels than 7 cwt. of a special mixture 

 applied under the same conditions. 



The Staffordshii-e exjierlments showed that for fertilizing grass lands super- 

 l)hosphate is nmch more effective than I>one meal or pure dissolved bone, and that
