somewhat cheaper than drilling.'' In a 3 years' test at Spartanburg in 

 which 2 plats were topi)e(l and 2 left untopped, " topping was of no 

 benefit whatever to the crop." 



To "i)rotect the soil during the winter and supply it with vegetable 

 matter when plowed under in the spring," oats were sown at both larms 

 in the fall, between the rows of cotton, on fertilized and unfertilized 

 plats and on plats to wliich the cotton seed was returned each year. 

 I'rom the results for 3 years the indications were that the oats were of 

 no benefit to the soil. 



For 3 years, trials were made at both farms of sowing cowpeas between 

 the rows of cotton on fertilized and unfertilize<l jilats, and on plats to 

 which the cotton seed was returned each year. At Spartanburg "in 

 consequence of the character and condition of the land and the unfa- 

 vorable seasons, the pea crop was a comparative failure every year." 

 At Darlington, however, both the fertilized and the unfertilized plats 

 where peas were sown gave decidedly larger yields than those without 

 peas; and on the plats where the cotton seed was returned there was a 

 sliglit increase witli peas. At Darlington in a rotation experiment in 

 growing cotton in 1888, peas in 1889, and cotton again in 1800, '• the 

 I)ea croi) of 1889, in connection with the marl of the other years, 

 increased the crop more than fivefold.*' Trials of replacing the nitrog- 

 enous fertilizers by a crop of cowpeas as green manuie, gave results 

 which, considering the cost, were very fiivorable to peas.

Fertilizers on wheat, J. F. Duggar, M. S. (pp. 3-10). — A test 

 w^as made on 19 twentieth acre plats, 3 of which remainc<l unfertilized, 

 the other HJ receiving kainit, superi>hosphate, ammonium sulphate, 

 nitrate of soda, cotton seed, cottonseed meal, and barnyard manure, 

 singly and in a variety of combinations. The fertilizers were applied 

 as toi)-dressings ^March 24. The land was very poor and it proved to be 

 quite uneven, so that the results furnish no definite indications of the 

 needs of the soil ibr this crop. For instance, the largest yield — 14.17 

 bushels per acre — was with barnyard manure; but an adjoining plat 

 receiving the same amount of this manure gave only 8.17 bushels. 

 Kainit seemed not to afiect the yield. Both nitrate of soda and sul- 

 phate of ammonia seemed to be effective. The jields are tabulated.
