and advice as to varieties most likely to succeed under certain conditions 

 will be given on request. The College of Agriculture does not grow 

 varieties of seed com for sale or for general distribution. The varieties 

 that should be tested are mainly in the hands of seedsmen and individual 

 growers. An effort will be made to procure seed corn of the best varieties 

 for trial tmder suitable conditions. From time to time a few varieties 

 of proved merit should be sent out from the College to those localities 

 where there is sufficient interest in corn growing. At this time we desire 

 the cooperation of several persons in a locality for the purpose of testing 

 com varieties. A systematic study of all com varieties grown within 

 the State should be made with the help of the corn growers themselves, 

 and the results published when the study is completed. 



SUMMARY 



A number of representative New York varieties of com have been tested 

 in cooperative experiments during the last three years. The most impor- 

 tant results may be summarized as follows: 



Elevation above sea level influences the climate of a locality to a large 

 degree. The type of soil used is also of importance in corn growing. 

 A high elevation, combined with a soil type not well suited to corn, caused 

 failure or very poor results with some varieties acclimated to other loca- 

 tions that were more favorable. Better soils and lower elevations pro- 

 duced very different results, especially with dent varieties of com. 



For elevations of 1,000 feet or more above sea level, varieties of flint 

 com seem better adapted to produce ripe grain and stover than do dent 

 varieties. For silage purposes there are a few good flint varieties and 

 some early dent varieties that are preferable to very late dent varieties. 



At elevations lower than 1,000 feet above sea level but above 600 feet, 

 there are some flint varieties that can be depended on to yield better crops 

 of sound mature corn than do dent varieties of equal earliness. For 

 silage purposes there are both dent and flint varieties that are sufficiently 

 productive and grow to reasonable maturity in a normal season. 



For elevations lower than 600 feet above sea level, varieties of dent 

 com as a class will produce more satisfactory yields of grain and stover, 

 or fodder for the silo. Early-maturing flint varieties are not productive 

 enough for the lower elevations. 



More thorough experimenting in localities where com is an important 

 crop are needed in order to determine the varieties best adapted for either 

 grain or fodder production. All local varieties of com should be tested 

 by several persons during the same season, with such outside varieties 

 as seem likely to succeed under prevailing climatic and soil conditions.
