Of the 43 winter wheats tested at Arlington Farm, 1 1 are selections 

 from hybrids which have been developed at College Park and Arling- 

 ton Farm. The most promising of these hybrids is the Virginia, 

 C. I. No.. 3277. 



The five leading varieties of wheat at College Park, with the 7-year 

 average yield of each in bushels per acre, are as follows: China, 31.17 

 bushels; Mammoth Red, 31.09 bushels; Bearded Purple Straw, 30.95 

 butehels; Turkish Amber, 30.11 bushels; and Lancaster, 30.03 bushels. 



The five leading varieties of winter wheat at Arlington Farm, with 

 the 5-year average yield of each in bushels per acre, are as follows: 

 Purple Straw (C. I. No. 1915), 32.09 bushels; Lancaster, 29.74 bushels; 

 Dawson Golden Chaff, 29.37 bushels; Fultz, 29.17 bushels; and 

 Purple Straw (C. I. No. 1957), 29.17 bushels. 



A rate-of -seeding test with several varieties of winter wheat at 

 Arlington Farm indicates that better yields may be obtained on well- 

 prepared land from sowing 3 or 4 pecks than from heavier rates of 

 seeding. 



Several varieties of winter spelt and one of emmer have been tested. 

 The best variety of winter spelt, the Alstroum, has a 6-year average 

 yield at College Park of 63.23 bushels and a 5-year average yield at 

 Arlington Farm of 74.08 bushels. The Black Winter emmer has 

 averaged 36.57 and 22.33 bushels, respectively, for the same periods 

 at College Park and Arlington Farm. 



A varietal test of rye has been conducted at Arlington Farm only. 

 Of the 12 varieties and selections tested, the Giant Winter, Virginia 

 Winter, and Abruzzes are the leading varieties. The average yield 

 of Giant Winter rye in a 4-year test was 32.89 bushels. Earlier 

 seeding than is commonly practiced by the average farmer has given 

 very satisfactory results with this crop. 



The leading varieties of winter oats at College Park are the Winter 

 Turf, Bicknell, and Culberson, in the order named. The most prom- 

 ising at Arlington Farm are the Red Rustproof, Winter Turf, Bick- 

 nell, and Culberson. 



The Winter Turf is the hardiest and most dependable variety, but 

 its late maturity and tendency to lodge are objectionable. The Cul- 

 berson and Bicknell mature ten days to two weeks earlier than the 

 Winter Turf and are to be preferred to it in eastern and southern 

 Maryland and eastern Virginia. 



The leading varieties of winter barley at College Park are the Mary- 

 land Winter, Mammoth Winter, and Tennessee Winter. These 

 varieties are practically identical. Of the varieties tested at Arling- 

 ton the Tennessee Winter, Wisconsin Winter, Maryland Winter, and 

 Texas Winter yielded best. 



None of the eighteen 2-rowed spring barleys that have been grown 

 from fall seeding at Arlington Farm have been satisfactory. A hybrid
