EXPERIMENTS IN WHEAT AND GRASSES. 



BY JAMES CLAYTON, ASSISTANT IN HOKTICULTURE, 



These experiments in varieties of wheat were begun in 

 1890, the results of which were published in bulletins 32 and 

 39, but as further investigation was necessary before defi- 

 nite conclusions could be drawn, the experiments were 

 continued in 1892. 



The land used had been planted in vegetables for a suc- 

 cession of years, had been highly fertilized and was in a 

 good state of cultivation. 



On the 16th November, 1892, the ground was broken 

 flush, plots each 1-100 ot an acre were measured, rows laid 

 off with a scooter and a mixture of 600 lbs. cotton seed meal 

 and acid phosphate, equal parts of each, applied at the rate 

 of 400 lbs. of mixture per acre broad-cast, and 200 lbs. in 

 the drill. A scooter was run in the open furrow after the 

 fertilizers were distributed, to mix them with the soil, and 

 wheat at the rate of 1^ bushels per acre was planted in the 

 drill and covered with a harrow. 



The following is the analysis of the acid phosphate and 

 cotton seed meal, as furnished by Dr. N. T. Lupton, State 

 Chemist, Jan. 21, 1893, 



ANALYSIS. 



Edisto Acid Phosphate: Water Soluble 9.73, Citrate Sol- 

 uble 4.83, Acid Soluble 1.41. Total 15.74. Cotton seed 

 meal. Acid soluble 2.73, Nitrogen 6.58, Potash 1.43. 



The names of the varieties sown with results, and a brief 

 description, are given below. The Large Red and Large 

 White Wheat were furnished by the U. S. Department of 

 Agriculture, and were first sown on the station in 1890. 



The Purple Straw was obtained in the neighborhood of 

 Auburn, and the twelve other varieties were presented by 

 James Carter & Co., High Holborn, London, England.
