and No. 19751, a tall, slender, sweet-stemmed, red strain, of probable vahie as 

 a dual purpose sorghum. No. 21936 was a very drought-resistant, leafy-dwarf 

 type, and 19775, tall, sweet-stemmed and entirely distinct from the remainder. 

 Among 60 recent sorghum introductions, 39 failed to head and none made 

 satisfactory growth, but 4 of unusual leafiness may be of value for hybridiza- 

 tion and for soiling and ensilage purposes in the South. Of those that pro- 

 duced heads all were dry and lacking in sweetness, but Nos. 23361 and 24126 

 were drought resistant although otherwise not superior to the native red 

 variety. Of 15 sorghums received late and planted May 21, all were killed by 

 drought, while 8 pennisetums from Africa and India, planted the same day, 

 were still less drought resistant, but Nos. 25343 and 24446 were most resistant. 



Breeding work was taken up to increase leafiness, juiciness, sweetness, seed 

 yield, and feeding value. Milo maize head rows varied from 11.8 to 13.8 in 

 leafiness. Although the seasonal conditions and rate and date of seeding 

 affected the leafiness, " the selections this season have shown no advancement," 

 but progress is expected in future favorable seasons. Attempts to obtain 

 cross-pollinated seeds from Fetertia and Black-hulled Kafir failed and in 

 future the flowers will be washed in the hope of better results. 



In close drilled seedings. Sumac excelled other sorghums in yield and 1 bu. 

 Ijer acre proved the optimum rate of seeding. Orange and Minnesota Amber 

 planted from * to 1 in. apart in the drill produced the heaviest yields. 



A test of 13 sorghum-legume mixtures indicates that Brabham and Iron 

 cowpeas and Dnlichos Mflorus are the best legumes for this purpose and D. 

 biflorus is most drought resistant. An Amber-Whip-poor-will mixture in the 

 ratio of 1 : 7 produced the maximum yield of forage obtained with cowpeas, of 

 3,600 lbs., while an Amber-Z>. hiflorus mixture yielded 4,400 lbs. per acre. It 

 was found that mixtures yield best when sown in drills, but will not feed readily 

 through the ordinary grain drill. The shock of the harvester sickle caused 

 the leaves to fall from the cowiieas and pack very solidly under the lower ele- 

 vator chains. 



In a test of 5 varieties of cowpeas, Brabham produced the heaviest yield 

 but was excelled by Iron in drought resistance, while Cream and Common 

 Whip-poor-will were excelled by Chinese Whip-poor-will in yield, earliness, 

 and drought resistance. Larger yields were secured from plantings of cow- 

 peas in IS-in. rows than in 36-in. rows, but the reverse was true in plantings 

 of Kulthi and Moth Beans. The latter excelled the former in yield per acre, 

 but lacked drought resistance. 



Among 12 varieties of peanuts the small Spanish and Tennessee Red excelled 

 the remainder and proved about equal in the production of forage. Sowings 

 of alfalfa gave negative results and seeding in rows proved less satisfactory 

 than broadcast plantings. Millets planted in 36-in. rows and cultivated made 

 promising growth in some cases. Of 18 foxtail millets the most promising was 

 the Big German variety, 20694. Three Burmese varieties reached a height of 

 3 ft. but were late and a little coarse. None of 6 Proso or 4 Eleusine millets 

 proved of value and the barnyard millets lacked drought resistance. Plantings 

 of hairy vetch with oats, 8 miscellaneous legumes, Chloris gayana, Eragrostis, 

 AstreMe triticoides, Andropogon leucopogmi, Laganaria, and Leguna corn gave 

 negative results. Sorghum halapense, No. 25017, proved entirely devoid of root 

 stocks, reached a height of 4* ft., suckered about as native Johnson grass and 

 was moi-e seriously affected by drought, but recovered quickly after cutting 

 even under drought conditions. 



Rescue grass seeded in October produced a good crop of seed early in the 

 spring. The plat was then plowed, planted to cowpeas, cultivated 3 times and
