Cornell 29-3 and Mass. 62 returned 

 over 7000 lbs. of dry matter to the 

 acre for silage. 



At Claremont Junction on the 

 Connecticut River terraces, in spite 

 of late planting in June, corn yields 

 were exceptionally high. Several of 

 the Wisconsin hybrids, Cornell 29-3, 

 Mass. 62. and a new Pennsylvania 

 hybrid, were outstanding 



The highest recorded yields of 

 silage corn in New Hampshire were 

 obtained at Durham where two 

 Connecticut Agricultural Experiment 

 Station sweet-dent hybrids produced 

 averages of over 10 and 11 thousand 

 lbs. of dry matter per acre. Gener- 

 allv, 9000 lbs. is considered to be a 

 high yield. Sweet-dent hybrids, al- 

 though potential silage yielders, 

 should not be used for grain because 

 of the presence of some hard kernels 

 on the ear.

Disease-Resistant Oat Varieties 

 Adapted to the New Hampshire Cli- 

 mate. Disease-resistant oats insure 

 better returns whether they are 

 grown as an annual hay crop, as a 

 nurse crop to be grazed off, or are 

 harvested for grain. Since 1943. 

 when the Agronomy Department of 

 the University of New Hampshire in 

 co-operation with the U. S. Depart- 

 ment of Agriculture established the 

 uniform oat trials, the new disease- 

 resistant varieties have not only 

 been accepted in the state but also 

 larger percentages of disease-resist- 

 ant seed have been planted each year. 



In 1948, oat trials identical to 

 those of the University Farm at 

 Durham, were carried on at Lancast- 

 er and Claremont. These triplicate 

 plantings were made so as to have 

 oats growing in reasonably import- 

 ant crop areas and to note the effects 

 of differences in climate. 



The 1948 oat trials gave the fol- 

 lowing results: 



Oat hybrids of the Bond parentage 

 such as Clinton, Mohawk, Benton, 



and the Canadian variety Ajax gave 

 good returns in all three areas. 



Varieties which are resistant to 

 stem rust and Victoria Disease gave 

 higher yields than did those varieties 

 which are resistant only to crown 

 rust and smut. 



The ordinary Clinton variety con- 

 tinued to show considerable vari- 

 ability with numerous drooping 

 heads, while Clinton 59, an improved 

 strain, showed more uniformity and 

 returned better yields. 



Dr. F. A. Coffman of the U. S. 

 Department of Agriculture visited 

 the Durham trials and found little 

 evidence of crown rust race 45 which 

 has been harmful to certain varie- 

 ties including Clinton. 



The non-disease resistant and ordi- 

 nary check varieties gave better re- 

 turns in the Lancaster area than they 

 did in either of the more southern 

 areas. 



Oat forage yields averaged better 

 than five tons to the acre and grain 

 yields were 75 bushels to the acre. 

 Before the disease-resistant varieties 

 were introduced into New Hamp- 

 shir, yields of 25-30 bushels per acre 

 were considered typical.

New Potato Varieties Show Prom- 

 ise. Ontario, a scab-resistant potato 

 developed in New York State, is one 

 of the most promising new potato 

 varieties that has been tested in the 

 potato variety program. The On- 

 tario yields well, is a good cooking 

 potato, has a certain resistance to 

 late blight, and is exceedingly resist- 

 ant to potato scab. Tuber unit seed 

 stock was produced in 1947, and 

 again in 1948, to supply in quantity 

 to one certified seed grower in the 

 Colebrook area. 



The demand which developed for 

 Ontario seed from growers who were 

 attempting to grow potatoes on land 

 that had been limed, far exceeded the 

 supply of certified seed produced in
