Eff1':cts of Limf on Cowpeas. 



Two tests were made on this poiat, using drilled cow- 

 peas of the variety Wonderful, fertilized with acid 

 pliosphate and cultivated several times. 



In 1897, on rcMldish loam soil, and stilTer than that in 

 the later tests, the yield was 5.G bushels of peas without 

 lime and onlv 5.2 bushels where slaked lime at the 

 rate of 040 pounds per acre had l)een applied broadcast 

 in February of the preceding year. Whatever lime re- 

 mained in the soil was evidently of no benefit of cowpeas. 



In March, 18U8, water slaked lime was used as a 

 itop dressing on oats on gray s^ndy soil. It was used at 

 the rate of 1,000 pounds per acre of the Unslaked lime, 

 which" is equivalent to a much larger weight of the 

 slaked material. 



After the oats Avere cut the land was plowed and cow- 

 peas drilled in and cultivated as necessary. The yield 

 follows: 



l*lot not limed, 13 bushels cowpeas per acre. 



Limed plot, 10.2 bushels cowpeas per acre. 



Clearly lime was of no benefit, but apparently injur- 

 ious as regards seeil formation. There was no notable 

 difference in the appearance of the vines. 



Fertilizer Experiment. 



This test was made in 1898 with AMiip])Oi'will cowpeas 

 on gra}^ or white sandy soil on a hilltop. Two cultiva- 

 tions were given, requiring altogether three furrows per
