26 EXPERIMENT STATION EECOED. 



A comparison of hu-ge, medium, and small-sized seeds of cereals, roots, and 

 rape sbow that the large seeds surpassed the small seeds by 19.1 percent for the 

 cereal crops. 60.1 per cent for the root crops, and 40.3 per cent for the rape. 

 The average of all results with plump and shrunken seeds of l)arley. spring 

 wheat, and winter whe.-it show that the plump seed gave a yield of 2<».2 per cent 

 more than the shrunken seed. 



Six-year tests with s(mnd and l»roken seed of barley, winter wlieat. and peas 

 gave the following results: Barley, sound seed 53.8 bu.. broken seed 4(; bu. : 

 winter wheat, stmnd seed 4(;.!t bu., broken seed 0.3 bu. ; and peas, sound seed 20.2 

 bu.. broken seed 10.2 bu. 



Emmer and spelt were sown as early as the land could lie cultivated in the 

 spriug and at intervals of 1 week afterwards until 8 different seedings had been 

 made. In every instance emmer gave better results than spelt. Ennner pro- 

 duced the largest crop from its second seeding and spelt from its first. There 

 was but little difference in the yields from the first 7 seedings of euuuer, sliow- 

 ing that this crop may be sown late in the season, while spelt must be sown as 

 early as possible in the spring in order to get the best results. 



In growing a mixture of grains for feeding purposes the largest yield of grain. 

 2,612 lbs. per acre, was obtained from a mixture containing 1 bu. of oats and 14 

 bu. of barley. For an early ripening crop it was found that I>aubeney oats and 

 Mandscheuri barley made an excellent combination, while with Siberian or 

 Banner oats, the later 2-rowed barleys, as Chevalier or Canadian, are to !)e 

 preferred. 



An experiment to ascertain the relative value of different kinds of grain when 

 in a mixture, in comparison with the same grains when grown separately, 

 showed that barley and oats produced the largest percentage of grains in the 

 resulting crop, while ennner ])roduced but a small i)ercentage. showing that 

 while it is a heavy yielder when grown alone it is not so \\'ell suited for grow- 

 ing in combination with other crops. 



During the past 18 years 287 varieties of oats have been tested at the college, 

 and among the 53 varieties which have been grown for the last 5 years 15 have 

 given average yields of more than 100 bu. per acre, Banner standing first with 

 100 bu. Among the early varieties Daubeney is i)erhai)s the most promising in 

 yield and quality, while other good sorts are Prosperity. Alaska, and Early 

 White Pearl. 



Four standard varieties of 6-rowed varieties have now been tested for 17 

 years in succession, with the following results : Mandscheuri 70.6 bu., Oderbruck 

 64.2 bu.. Common 6-rowed 61.!» bu.. and Mensury W.2 bu. per acre. California 

 Brewing gave a somewhat larger yield than Mandscheuri in the average of the 

 last 5 years, but its weight per measured bushel was only 4(5 lbs., as compared 

 with 50 and 52.6 lbs. for most of the other varieties. The beardless varieties 

 have given nmch lower yields of grain than the others and their grain is de- 

 cidedly light in weight. Five of the b(>st varieties of 2-rowed barley gi'own for 

 5 years gave the following yields: Iowa No. ."m'.W), 72.3 bu. ; Iowa No. 5591. 71.2 

 bu. ; Jarman Selected. 71.2 bu. ; and Selected Canadian Thorpe, 68.5 bu. per acre. 

 Among the varieties of hulless barley tested for 5 years. Guy Mayle stood lirst 

 with a yield of 53.2 bu. per acre, followed by Hungarian with 50.3 bu., and BI.mcI^ 

 Hulless with 49.1 bu. The yields of hulless barley are reckoned at the rate of 

 60 lbs. per bushel. In 9 out of the past 14 years fair yields of winter barley 

 have been secured at the station, but in the other 5 years the crop was almost 

 completely winterkilled. 



Among (*)1 varieties of winter wheat grown in 190(;. Abundance stood first in 

 yield with .50.4 bu.. and Prize Taker second with 50.2 bu. These 2 varieties aie 

 both white wheats, very closely resembling the Dawson Golden Chaff. Russian
