TlLLAfrK ExPERT:NrEXTS ^VTTII POTATOES. 203 



Result : The plat cultivated six times yielded 187 bushels per acre, 

 while the plat cultivated seven times yielded 194 bushels, a gain of 

 seven bushels for one extra cultivation. 



TJiree extra cultivations. — 



A. B. Hayes, Niagara Co. Soil, sanely witli a white sand subsoil. 

 Plats treated every way alike except that the special area received 

 three extra cultivations once in a row. 



Result : The field culture yielded 119 bushels per acre and the special 

 area 140, a g-ain apparently due to the three extra cultivations of 21 

 bushels. 



Three cultivations hilled vs. Jive cultivations level. — 



Emery Osterhont, Schoharie Co. Soil, a yellow loam. The plats 



were treated alike except as stated above, and that while the field 



was gone over once with a spike tooth harrow and once with a 



weeder before plants were up, the special area had an extra working 



with the harrow. 



Result: Three cultivations, hilled, 152 bushels per acre; five cultiva- 

 tions, level, 167 bushels, a difference of 15 bushels per acre in favor of 

 the latter. 



Three cultures hilled vs. nine cultures level. — 



H. L. Beadle, Washington Co. This experiment was in the same 

 Held as that given from Mr. Beadle on page 19S. The jDreparation 

 and the planting were tlie same, and both were sprayed twice with 

 Bordeaux mixture. Nothing was done to the first plat till plants 

 were up, after which it was worked three times, hilled and hand 

 hoed, the last work being done July 6th. The other plat was 

 dragged twice before plants were up, and cultivated nine times 

 level, the last working being Aug. 8th. 



Result : The three cultures, hilled, gave 252 bushels per acre, while 

 the nine cultures level gave 311 bushels, a difference of 59 bushels in 

 favor of the continued level culture. 



Mr. Beadle has followed this experiment of hilling vs. level tillage 

 of potatoes for several years, and in his letter gives the following 

 summary : 



In 1895 the difference in favor of hillino^ was Y3 bushels. 

 In 1896 the difference in favor of hilling was 11 bushels. 

 In 1897 the difference in favor of level culture was 37 bushels. 

 In 1899 the difference in favor of level culture was 59 bushels.
