more than snfBrient) for the needs of the crop and soil. (3) Of the three potassic 

 manures tested, one kind wa-s ahotit as ertVctiveaa another (when equivalent amounts 

 were applied). Hence the employment of any one of the three is simply a question 

 of its cost. 



(3) Modes of applying fertilizers for corn. — A comparison ot fertilizers 

 applied broadcast aud in drills on the same plan as that followed in 

 1888. The indications were the same as in the preceding year, i. e. 

 "the two methods of ai>plyin<.;- manures gave practically the same 

 average returns." 



(4) Modes of planting corn. — A 2-years' trial of planting in drills 

 and hills (checking), according to the i)lan dctaih'd in tlie first year's 

 report, seemed to show '' that one method of jtlanting gave about as 

 good results as the other, and that it madelitth' tlitiereuce whether the 

 rows were 5 or C feet apart, or the checks 5 feet by .'3 feet or G feet by -J 

 feet." 



(5) Modes of cultivating com. — As in ISSS, this was a test of "(1) the 

 advantages of sub.soiling the seed furrow before i»lanting; (2) the com- 

 ])arative effe«'ts of deep and sliallow <'ulti\atiun: and (."») the value of 

 tliorniigli cultivation." As between the ditVeient methods tlic residts 

 for the 2 years showed •• siir]»risingly little diflerence. • * • It 

 a]i]>ears that subsoiling tlie seed fuirow did not improve the crop, :nid 

 tliat deep culture and imperfci-t tillage did not materially alVect it. It 

 should be explained, however, that our 'ordinary cultivation." that is 

 the cultivation given to all the otlu'r plats, was much more thorough than 

 the tillage given on the average farm." It is l>clieved that the advan 

 tages of thor(Migh cultixation would have been more api>arent on heavy 

 soils than on the light soils used. 



(6) Varieties of corn. — Tests at the Columbia farm of 1> varieties of 

 corn. 



(7) Rotations for corn. — Tabulat^'d data on the yields in iss<» ,»| tlu» 

 series of rotaticms for corn eomnu'uced in 1888. "Up to this time jno 

 tective and green crops |oats and jieas] grown along with the coin have 

 not nmterially alfected the yi«'ld one way or another." 



IJ.ipcriincnts with cotton (pp. 2<»8-.'U2). — "TheexperinuMits with cotton 

 may be classified as follows: Tests of varieties, fertilizers in general, 

 nitrogenous nninurcs. ])hosphatic manures, ]>otassic manures, composts, 

 methods of ai)])lying manures, time lor applying nitiate of soda, modes 

 of planting, top}>ing. and rotations, * » * Amounts of jtotash. jihos- 

 phoric acid, and nitrogen found by analysis in a crop yielding .?(►(► poumls 

 of lint i)er acre were ajjplied, except where otherwise mentioned. These 

 are callecl the full amounts nr doses." 



The season of 1SS;> is said to have been very unfavorable for eott«m 

 in many ]tarts of the State. 



(1) 7V.s7.s of rarirtiis. — The results are given t»f tests of 1.") \aiieties 

 of cotton at Spartaid>urg, 47 att-obuubia, and 18 at Darlington in 1SS!»: 

 the averages of 8 varieties tested at all three farms for 2 y«'ars: and 

 the averages for varieties tested for several years at the Columbia farm
