the protein content of the forages grown in Groveton was higher and the 

 crude fiber lower than the counterparts grown and harvested at North- 

 wood. This indicated that plants were less mature in Groveton than 

 those cut on the same date at Northwood. In neither 1961 or 1962 was 

 there enough growth of Essex timothy at Groveton to warrant taking a 

 harvest on June 1st. By June 30, the growth of the Commercial timothy 

 at Groveton was such that yields averaged higher than at Northwood 

 for plots receiving the same rate of nitrogen. The yields at Northwood, 

 in 1960, were reduced by lodging on the plots receiving 100 and 150 

 pounds of nitrogen per acre. The most lodging was noted on the plots 

 receiving 150 pounds of nitrogen harvested on June 30, 1960. The low 

 residual levels of phosphorus and potassium may have been partly re- 

 sponsible. In 1961, the yields of June 1 and 15 were lowered because of 

 the below-average temperatures at both locations. In most cases the 

 total yield for the year was highest for the plots receiving 150 pounds of 

 nitrogen (see Table 2). The influence of climate in relation to day 

 length and temperature has been expressed in terms of "Growing Degree 

 Days" (11). The "Growing Degree Days" were greater in Northwood 

 than Groveton.
