 + Not significant. 



By the spring of 1954, most of the Ladino clover had died. Similar 

 results have been obtained elsewhere in that the second winter appears 

 to be critical for survival of Ladino clover. For this reason, a random 

 block instead of a split plot analysis was calculated for the 19.54 data, 

 considering only those plots originally seeded to bromegrass. 



Table 5 shows the comparison in yield between the bromegrass plots 

 and the plots seeded to the mixture. In the first harvest season, when the 

 Ladino clover was present, the plots in the mixture produced almost twice 

 as much forage. In 1954, plots seeded to bromegrass alone yielded about 

 as much as the mixture. The bromegrass in the latter plots was noticeably 

 darker in color, however, and it appeared that the grass was still obtain- 

 ing appreciable nitrogen due to the heavy growth of Ladino the previous 

 season or the decaying organic matter. 



A considerable amount of Ladino was present in 1955 and 1956 in the 

 plots originally seeded to the mixture. It is believed that most of this clover 

 resulted from natural reseeding in 1953. Small, bare areas in the plots in 

 1954, where the original Ladino plants had died, provided an opportunity
