[Field crops] , J. W. Fox {Mismtisiiypi /S7rt. Jiul. JOG, pp. 2-6').— The work with 

 fiePl crops here reported was condncted at the Delta station in lOOfJ. Of 10 

 varieties of cotton, Cook Improved and iNIoss Inu)roved ranked first in the 1 in. 

 staple class, with an average yield of 5G0 lbs. of lint cotton i)er acre, Trinuiph 

 and Lewis I'rize l*roliflc first in the IJ in. staple class with 550 lbs. of lint 

 cotton, Southern Hope and P>lack Rattler in the lA to 1^ in. staple class with 

 350 lbs. of lint cotton, and Sunflower and Allen in the If to IJ in. staple class 

 with 340 lbs. 



It was found that on old Delta land receiving from 300 to 500 lbs. of cotton- 

 seed meal per acre a variety of cotton not a rank grower gave the best results 

 during a moderately dry season when planted in 4 ft. rows and 2 ft. apart in 

 the row. 



From the resnlts of fertilizer tests it appeared that nitrogen was the only 

 element needed and that this could be applied to light lands in cotton very 

 I)rofitably. Phosphoric acid or potash gave no increase in yield when applied 

 to cotton, corn, or cowpeas. The yield of seed cotton per acre was increased 

 from 960 lbs. to 1,500 lbs. by the use of 450 lbs. of cotton-seed meal. 



A comparison of different forage crops showed that alfalfa sown the pre- 

 ceding fall yielded 6,300 lbs., red clover 5,S00 lbs., fall sown oats 5,200 lbs., 

 and peas after the oats were cut 3,500 lbs. of hay per acre. It is re])orted that 

 alfalfa has been successfully grown on all the stiff or buckshot lands, but that 

 it has not done well on light sandy lands. An average yield of 41 bn. of corn 

 per acre was secured under ordinary field conditions. 



Experiments with, cotton and corn in 1906, J. F. Duggar and J. M. Riche- 

 SON {Alubaiiia Caiicbrakc Sta. Bui. 2.'i, pp. 21). — Weather conditions interfered 

 to some extent with the experiments here reported. Six varieties of cotton 

 grown on bottom land ranked in the value of lint and seed per acre in the 

 following order : Toole, Cook Improved, Russell, Truitt, Hastings Improved, 

 and Culpepper. The value of the lint and seed ranged from $36.34 to $51.50 

 per acre. The average results of 4 years are in favor of plowing 6i in. deep, 

 as compared with 4* and 3i in. Leaving 1 plant per hill 3 and 4 ft. apart, or 

 a total of 3,568 plants per acre, gave 192 lbs. of lint, while an acre of drilled 

 cotton with 6,112 plants yielded 256 lbs. The yield per plant on the check 

 plat was 0.053 lb. of lint and on the drilled plat 0.042 lb. 



Flowing under the entire growth of cowpeas apparently increased the yield 

 of lint cotton per acre by 272 lbs. Corn following a poor stand of alfalfa 

 gave 11 bu. per acre more than the check test. In a rotation test it was found 

 that by phnving under melilotus stubble or the entire growth of cowpeas sown 

 in the preceding crop of corn at the last cultivation the following crops of 

 corn and cotton wei"e greatly increased. 



Three years' fertilizer experiments on reddish prairie land showeil that 

 cotton -seed meal and nitrate of soda were applied to cotton at a decided profit 

 either alone or in combination with acid phosphate. The use of acid phosphate 

 was usually profitable, but the use of kainit was almost uniformly unsatis- 

 factory. Cotton-seed meal and kainit wer(> apitlied at the rate of ."{20 lbs. per 

 acre, and acid ph(»sphate at the rate of 324 lbs. The average increase of lint 

 cotton i)er acre with cotton-seed meal was SS lbs., and with acid phosphate 

 8 lbs., whereas with kainit there was an average decrease of 13 11)S. On 

 white prairie land both cotton-seed meal and acid iiliospbate were iirotitabh? 

 for cotton, but the results with kainit were again doubtful. On black slough 

 land little or no Increase from any fertilizer for cottr)n was obtained. An 

 iuteusive aiJlJiicatiou of fertilizers for cotton, consisting of 200 lbs. each of
