Because the length of growing sea- grain corn and silage corn that are 



son varies considerably in New recommended for New Hampshire, 



Hampshire, it seems advisable to depending upon the number of days 



make our recommendations in rela- available between the time of plant- 



tion to this condition. The follow- ing and the first killing frost in the 



ing chart shows the varieties of both fall.

Oat Varieties. Oat varieties have 

 been tested since 1943. Disease- 

 resistance is the most important fac- 

 tor to consider in selecting an oat 

 variety for any part of the State. 

 Results of the past few years indi- 

 cate that the best varieties for our 

 conditions are Ajax, and the new 

 bond crosses such as Clinton, Benton, 

 Zephyr, and Bond X Anthony. 

 Other varieties may yield high in 

 certain years but do not have suffi- 

 cient disease-resistance to be relied 

 upon.

Potatoes Yield Better When Mag- 

 nesium is Added to the Fertilizer 

 Mixture. In our potato experiments 



at Colebrook we added a complete 

 fertilizer and magnesium sulfate 

 (supplying 40 pounds per acre of 

 MgO) to one set of plots and com- 

 plete fertilizer only (one ton of 

 5-10-10 per acre) to another set. 

 When the yields were obtained it was 

 found that on the average the addi- 

 tion of the magnesium sulfate in- 

 creased the yield 69 bushels per acre. 

 Individual plot yields, were increased 

 to as much as 110 bushels per acre. 

 It would appear that the Coos Coun- 

 ty potato farmer can well afford to 

 apply a fertilizer containing mag- 

 nesium.
