AGRICULTURAL RESEARCH IN NEW HAMPSHIRE 25 



Barley varieties have not proven as adaptable to this area as have the 

 oat varieties. The Wisconsin 38 variety failed in both 1941 and 1942, and 

 Alpha failed in 1942.

Corn Variety Trials 



Corn variety trials are stationed at the Whenal farm in Greenland in 

 southeastern New Hampshire. There are three classes of trials; flint corn 

 for grain, dent hybrid corn for grain, and silage corn. 



1. Flint Corn for Grain 



Twenty local varieties of flint were planted on May 15, 1942, There 

 were three randomized plots of each variety, and 22 hills in each plot. 

 Each hill was thinned to three stalks in order to maintain a near perfect 

 stand. 



On October 15, ears were picked from each plot and weighed. 

 Twelve ears were picked at random from each flint sample and then dried 

 to a uniform moisture percentage of approximately eight per cent. Using 

 the moisture correction, \ields were calculated on an equal basis. 



In 1941, 19 local flints were tested, 18 of which were repeated in 1942. 

 In general, those varieties which gave good or poor yields in 1941 repeated 

 their relative position in the yield table for the 1942 season. The average 

 yield of the two seasons ranged from 39 bushels to 56 bushels. Whereas 

 some high yielding varieties showed good maturity, others were too im- 

 mature to recommend as a good corn for grain in this area. 



2. Dent Hybrid Corn for Grain 



Twenty-two dent hybrid strains of corn for grain that showed some 

 promise for New Hampshire conditions were field tested in 1942 for 

 adaptation. These samples were grown and harvested in the same man- 

 ner as were those of flint corn. The yield per acre ranged from 45 bushels 

 to 77 bushels and averaged 58 bushels, which is slightly less than New 

 Hampshire 500, a selection from Minnesota 13 that has been grown in 

 southeastern New Hampshire for several years. Minnesota 700 yielded 

 64 bushels per acre, matured very early and had the least weight loss as a 

 result of drying. This hybrid shows considerable promise. These va- 

 riety trials are being continued in 1943. 



3. Silage Corn Trials 



During every year since 1936, a number of silage corn varieties, in- 

 cluding numerous new hybrids, have been tested for comparative adapta- 

 tion. Each year the better varieties have been continued and the poorer 

 ones have been dropped. During the 1942 season 22 varieties were tested 

 in such a manner that each was replicated three times in plots of 22 hills 

 thinned to three stalks per hill. Twelve hills from each plot were green 

 weighed and one hill was bagged and dried for weight calculations on a 

 uniform basis. As a result of repeated trials, three varieties show con- 

 siderable promise; namely, West Branch Sweepstakes, Lancaster Sure- 

 crop, and Cornell 29-3.
