EXPERIMENT STATION RECORD. 



Comparative average yields of hiylt protfin and uf Itnc prottin corn. liUO-liUS, 

 in hiishels per acre, and pounds of protein per acre. 



The .strain of corn selected for high oil content lu-odnced in 1911 an average 

 of 86.83 lbs. of oil per acre and in 1912, 216.97 lbs. The percentage contents 

 were 3.47 and 6.1, resijectively. The strain selected for low oil content pro- 

 duced 61.59 lbs. of oil per acre in 1911 and 170.66 lb.s. in 1912. The percentage 

 oil contents were 3.15 and 5.66, respectively. 



As a result of a study to determine the intlueuce of degree of maturity on 

 an oil content of corn it was found that corn harvested on August 15, Septem- 

 ber 4, and September 19 contained 3.272, 4.982, and 5.523 per cent, respec- 

 tively, an average composite sample of 40 ears each. It is suggested that the 

 degree of maturity at harvest may account for the wide differences in oil con- 

 tents of the 1911 and 1912 crops above citetl. 



Cotton experiments, 1914 (Mis.sis.^ippi. Sio. Bill. KW (lUL't), pp. 16). — This 

 bulletin gives results of cotton experiments similar to those previously noted 

 (E. S. R.. 29, p. 35; 31, p. 136). Itesults from tlie central .station are reported 

 by E. C. Ewing and J. R. Kicks. A table shows the monthly temperatures and 

 rainfall for 1914. A table giving the results of a variety test shows four early, 

 short staple varieties to range in yield of seed cotton from 1.287 to 1.570 lbs. 

 I)er acre, eight medium early, big boiled, short staple varieties to range from 

 1.303 to«1.5S9 lbs. per acre, and four long staple varieties to range from 1.154 to 

 1.430 lbs. per acre. 



In regard to the values of the different varieties for local production of 

 cotton it is stated " that under average conditions on ix)or thin land or land of 

 medium fertility, with the boll weevil present, the medium early, big boiled 

 varieties such as Wannamaker Cleveland, Cook, Half and Half (a selection 

 from Cook), and Miller will give better results than the very early, quick 

 maturing varieties, which suffer worse from drought and rust and quit growing 

 early under such conditions. Besides, there does not seem to be as much dif- 

 ference in earliness between the earliest and the latest varieties on thin land as 

 there is between the earliest and the latest varieties on rich land. On rich 

 bottom lands in the presence of the boll weevil, one of the early maturing 

 varieties that does not make too much stalk will be the most satisfactory. In 

 this class there are no better varieties than Trice and Dodd Prolific. In most 

 tests in this State Trice has given better results than Dodd Prolific. 



" We regard Express as the best available long staple variety for boll weevil 

 conditions. It is an early inch and three-sixteenths cotton that has given 

 splendid results in the Delta. Unknown is another good early variety that 

 runs from an inch and an eighth to an inch and three-sixteenths." 



The results of a test on wilt-infested land are reported, which show that " the 

 wilt-resistant varieties generally gave the be.st yields in 1912 and 1913. but fell
