202 Bulletin 191. 



This crop suffered severely from tlie extreme drought wliicli was 

 empliasized by tlie late 2)lowing, and the uiidecayed sod and manure 

 under tlie furrow. It was in such condition that tlie shovel plow- 

 intr at the last woi-kino; did its worst work. 



Harrowing after ]}lanting vntJi five cultivations vs. not harrow- 

 ing and two cultivations. — 



Y. C. Wood^ Lewis Co. Soil, gravelly loam with clay subsoil — 

 dressed with -100 lbs. per acre of one-four-eight fertilizer,^' plowed 

 May 3d, six inches deep, planted June 3d. The plats were fitted and 

 planted alike, and both were sprayed with Bordeaux mixture. One 

 was harrowed between planting and coming up and received five level 

 cultivations ; the other was not harrowed and received two level 

 cultivations. 



Result : 162 bushels per acre from the latter, and 176 bushels from the 

 former, a difference of 14 bushels per acre in favor of five cultivations. 

 However, owing* to the smaller proportion of culls on the special area 

 the gain in merchantable tubers was 27 bushels per acre. 



Yery similar to the above is the report of Fay C. Gordon, Lewis 

 Co. The plats were treated dike except that the special area was 

 harrowed before plants were up, received five cultivations (not hilled) 

 and once sprayed with Bordeaux mixture, while the other plat was 

 not harrowed, was cultivated twice and hilled twice, and not sprayed 

 with Bordeaux. 



K-esult : 172 bushels per acre for the former, and 170 bushels for the 

 latter — practically no difference. 



We are pleased to introduce this report here to call attention to 

 the fact that identical results may not be expected on different 

 farms even if in the same county and during the same year. How- 

 ever, the fact that impresses us most strongly as we look over these 

 raports is that so very few of the efforts to follow the suggestions 

 of the College as to methods of tillage give negative or neutral 

 results. Fully 85 per cent of the reports show positive results that 

 indicate financial ofain. 



Six cultivations hilled vs. seven cultivations not hilled. — 

 E. C. Corwin, Cayuga Co. Soil, clay loam with yellow clay subsoil. 

 The two plats were treated every way alike except as stated above.
