Experiments With Cotton. 



BY J. F. DUGGAR. 



SUMMARY. 



The group of varieties yielding most liut were Texas Oak, 

 GrifiBn, Hawkins, Deering, Mell Cross No. 15, Jones Re-im- 

 proved, Duncan, Hutchinson, Peterkin, Truitt and Whatley. 



Seed of the same original stock, but grown for one year 

 in different parts of the Cotton Belt, when planted at Auburn, 

 showed no marked difference in productiveness. 



The yields obtained by planting fresh, one-year-old and 

 two-year old seed were nearly identical. 



With late cultivation the yield of cotton was slightly 

 larger than with ordinary cultivation. 



Truitt cotton in narrow rows on upland of medium qual- 

 ity gave practically the same yields whether the single plants 

 stood 12, 18 or 24 inches apart in the drill. The yield de- 

 creased when the distance between plants was increased to 30 

 or 36 inches. The crop matured earlier with thick planting. 



Topped cotton plants yielded less than those not topped. 



The use of 640 pounds of slaked lime, applied broadcast ia 

 1896, failed to increase the crop that year. But cotton follow- 

 lowing broadcast cow peas, turned under in the spring of 1897, 

 afforded a larger yield on the pfot limed the previous year 

 than on the plot not limed. 



Subsoiling in January, 1896, was decidedly beneficial to 

 the flrsc crop of cotton, but afforded no increase in the second 

 crop, grown in 1897.
