summer drought. There were no significant yield differences for either the 

 population levels or the fertilizer variations. There were significant yield 

 differences in the average yields of all treatments for the varieties. The 

 earliest maturing variety returned better than 14 tons of silage per acre and 

 the latest maturing variety produced 22 tons per acre. Four hybrids gave 

 higher silage yields than Cornell 29-3. In this dry year all varieties matured 

 except the latest hybrid. 



A number of oat varieties were tested for forage as well as for grain sdelds. 



In 1954 the same set-up with respect to treatments was used. Three 

 earlier maturing hybrids were substituted for the three latest maturing 

 varieties of 1953. To date, the rainfall has been ample and observed differ- 

 ences have been noted. The higher amount of nitrogen used as a side- 

 dressing seemed to give the desired response. 



New Hampshire farmers planted the new Clarion oat in place of Clin- 

 ton for the first time in 1954. Results as regards yield and quality have 

 favored the Clarion over the Clinton in the northeastern uniform nursery 

 oat trials. The new improved Gerry and a New York selection appear to be 

 well adapted and high yielding in the trials. If they prove their worth, the 

 seed will be multiplied and available to oat growers. At this time, Clarion 

 and Ajax are the recommended varieties to plant.

Radioactive Phosphorus Absorption by Potato Leaves Shows that 

 Phosphorus Fertilizer Can Be Applied as a Foliage Spray 



Using phosphorus compounds tagged with radioactive phosphorus, it 

 was found that up to 3.5 percent of the total phosphorus in the tubers at 

 harvest time had been derived from the phosphorus sprayed on the potato
