June, 1940] Experiments With Potatoes 31 



TABLE XXX. Comparison of potato quality as influenced 

 by climatic conditions. 



This table appears to show that the more favorable potato climate in 

 the Colebrook area is conducive to the production of potatoes of h"gher 

 starch value and better cooking quality. While this was true of the 1938 

 season, we have reason to believe that such restilts might not always be 

 secured, and that in other seasons in which climatic conditions in central 

 or southern New Hampshire were more favorable for high yields, the re- 

 verse of these results might be expected. 



In support of this contention. Table XXXI is presented giving the 

 quality ratings of potatoes picked at random from fields of members of 

 the 300 luishel potato club in 1939. 



TABLE XXXL Quality ratings of potatoes from 

 300 Bushel Club members, 1939. 



Yield Quality 



Sample No. tested Poor Fair Good Excellent per acre rating 



be-low 1.070 1.075-1.080 1.085-1.090 1.095-1.110 



The potatoes in this table are all of the Green jNIountain variety and 

 represent fields from northern New Hampshire as well as other sections of 

 the state. Growers represented by sample Nos. 5, 6. 7. and 10 are from 

 Coos county, the most northern county in the state, while those of Nos. 1, 

 4. and 9 are from Cheshire, a county in extreme southwestern New Hamp- 

 shire. Of the other dn-ee, two are from Grafton, bordering Coos county 

 on the south, and one from Belknap county in central New Hampshire. 

 It will thus be seen that of ten growers having potatoes of the highest 

 quality ratings in 1939, the first four were outside of Coos county, and 

 three of the growers including those in first and fourth place were in the 

 southernmost cotmty of the state. 



Further data on quality ratings of potatoes produced on Jackson farm 

 in 1939 are shown in Table XXXII. The Chippewa variety was pro- 

 duced here in 1939, and this fact may account for seeming discrepancies of 

 data when compared with Tables XXVIII and XXIX. Subsequent data
