A fodder plant of growing importance in the United States 

 introduced in 1909 (Piper, seq.) and cultivated in Egypt for 

 the same purpose. It is suitable for hay, pasture and as a 

 soiling crop, better adapted for dry regions than " Johnson Grass " 

 {Sorghum halepense) and being an annual not so likely to become 

 troublesome in the same way; it comes to maturity in about 

 3 months. The stems are slender, 6-10 ft. high and apart from 

 the perennial character it has much the appearance of Johnson 

 Grass, from the seed of wliich it is difficult to distinguish. It 

 is recommended for growing in mixtures with *' Cowpeas '' 

 {Vigna Catiang) and "Soy bean" {Glycine Sjja) in the United 

 States (I.e.); in North Africa (Trabut, Le Progres Agric. Paris, 

 March 5th, 1916, p. 235) and might be given a trial in Nigeria. 



Seed may be sown broadcast or in rows about 3 ft. apart, 

 at the rate of from 4-S lb. per acre. An average crop is estimated 

 at from 3-5 tons of hay per acre; but in some trials with this 

 plant as a fodder crop, a yield of 1626 lb. per acre is recorded 

 (Walters, Rhodesia Agric. Journ. Oct. 1920, p. 433). Analysis 

 shows the hay to have a higher feeding value than that of
