1056 EXPERIMENT STATION RECORD. 



cassava roots secured at the station was at the rate of 15,000 lbs. per acre. Few 

 crops are believed to equal it in tonnage on the sandy soils on which it was tested. 



Deep preparation for corn, with shallow cultivation, gave better results than other 

 methods of treatment, while with cotton deep preparation and deep cultivation gave 

 practically the same yield as deep preparation and shallow cultivation. The deep 

 preparation of the land consisted of subsoiling to a depth of 18 in. during the spring 

 of 1903 and plowed to a depth of 5 in. during the spring of 1904, while for shallow 

 preparation the ground was broken 5 in. deep during both seasons. 



An inoculated plat of vetch grew to be waist high and was very strong and vigor- 

 ous, while an uninoculated plat gave very poor results. Notes are also given on rape 

 and Bermuda grass which were grown at the station. 



Report of field work done at the [Mississippi] station for 1904, W. R. 

 Perkins (Mississipjii Sta. Bui. 88, pp. 13). — Among 10 varieties of short staple 

 cotton the highest total value per acre, $49.02, was produced by Cook Improved. 

 The production of the least remunerative variety, Berry Big Boll, was equal in value 

 to $26.59. John Bull, a long staple cotton, and Cook Long Staple produced values 

 equal to $52.78 and $52 per acre, respectively. It is pointed out that the growing 

 of long staple cotton is not always the most profitable. The different varieties here 

 tested are briefly described. 



Ten varieties of corn were tested and among them Hick Improved Marlboro stood 

 first with a yield of 55.8 bu. per acre, followed by Columbian White Mammoth, 

 with 52.3 bu. The yields of soy bean hay from 4 varieties ranged from 3,880 to 

 6,148 lbs. per acre. Yields of Johnson grass hay on 3 different plats varied from 

 3.75 tons per acre to 5.91 tons. From an average fertilizer application of 87 \ lbs. of 

 cotton-seed meal and 100 lbs. of nitrate of soda a profit of $4.93 per acre was secured 

 in growing Johnson grass hay. The experience of the station in growing alfalfa has 

 been that crab grass is likely to kill out the alfalfa plants. 



The comparative value of oats, cowpeas, and corn for the production of forage was 

 studied. The value of corn fodder per acre amounted to $14.14, of cowpea hay to 

 $14.63, and of oats and cowpea hay to $16.11. 



Report on field crops at the Sugar Experiment Station, Audubon Park, 

 New Orleans (Louisiana Stas. Rpt. 1905, pp. 3-9, figs. 2). — It is reported that 

 seedling canes D. 74 and D. 95 have maintained the high standard of previous 

 years. This season D. 74 tasseled in several places in the State as well as in Florida, 

 and it is hoped that seedlings originating in Louisiana may be produced. Promising 

 results secured in, tests with cane loaders and harvesters are reported, and it is stated 

 in this connection that D. 74, standing erect and withstanding storms far better than 

 the native canes, presents less difficulty to harvesting with machinery. 



Among notes on various crops grown at the station it is reported that maximum 

 yields of 3,162 lbs. of seed cotton and 3,140 lbs. of cured alfalfa hay per acre were 

 secured. 



Cereal investigations (Kansas Sta. Rpt. 1905, pp. 20-26). — A description is given 

 of cooperative experiments with the Bureau of Plant Industry of this Department in 

 the testing of newly introduced varieties, and of hybrids and selections of cereal 

 crops. 



The work is carried on at McPherson and Fort Hays. Many of the results secured 

 have already been noted (E. S. R., 17, p. 129). The yields of the different varieties 

 of cereal crops grown in 1904 are tabulated and the extent of the plantings for 1905 is 

 outlined. The Aveather conditions and the growth of the various crops during the 

 season are discussed and the rainfall for the year beginning July 1, 1904, is recorded. 



The prevention of lodging- in cereals (Rev. Gin. Agron., 15 (1906), No. l,pp. 

 18-21). — The lodging of cereals is discussed and a method of preventing it described. 



It was found that on very rich soil by mowing luxuriantly growing grain when 30
