prevalent in this area, especially on imperfectly drained soils. It should be noted 

 that there probably is not complete resistance to the organism and that even 

 among varieties described as resistant there is varying degrees of bacterial wilt 



incidence. 



Annual fertilizer application consisted of 150 lbs/A of K2O after the first and 

 third cuttings. Three lbs/A of boron was applied in July 1974. Three cuttings per 

 year were taken. Plots were harvested with a Jari mower. Yields were based on 

 harvested areas of 3 x 13 feet. 



Timothy 



The timothy performance trial was established in a field adjacent to the 

 alfalfa trial. Establishment procedure was similar to that for alfalfa, except that 

 before seeding, 750 lbs. of 5-20-20 was applied. Ten timothy varieties and 

 synthetics were broadcast-seeded at 8 lbs/A on August 17, 1972, in a 

 randomized complete block experiment with 5 replications. 'Climax' was the 

 standard early- and "Essex' the standard late-maturing entry in the trial. Four 

 late-maturing experimental lines provided by Dr. C. C. Lowe, Dept. of Plant 

 Breeding and Biometry, Cornell University, were included. In early spring and 

 after the first cutting 330 lbs. of 15-10-10 was applied. The harvesting procedure 

 and yield determinations were the same as those for alfalfa. 



Smooth bromegrass 

 Test I 



This experiment was seeded August 12, 1969. It included six experimental 

 synthetics available in both the first and second generation of synthetics, plus 

 the six varieties 'Blair', 'Carlton', 'Fox', 'Manchar', 'Sac' and 'Saratoga', the 

 latter variety including the first, second and third generation of synthesis. The 

 single cross, 2017 x 4228, plus four N.H. synthetics were all developed from 

 only six parental clones. These were originally selected for leafiness and 

 resistance to brown leaf spot caused by Pyrenophora bromi. 



The land was fallowed in late 1968, then seeded to winter rye which was 

 turned under in spring 1969, followed by fallowing until August. It was 

 fertilized with 700 lbs/A of 10-20-10 prior to seeding. Seed was drilled at 

 approximately 12 inches between rows into 5-x 10-foot plots, with four 

 replicates of each entry. The single cross 3017 x 4228 germinated poorly for syn 

 1 generation, and was reseeded with the variety Sac on September 15, 1969. 

 Plots were cut twice/year on approximately June 10 and August 10. 

 Fertilization after establishment consisted of 400 lbs/A of 15-10-10 applied 

 three times/year in early spring and again after the first and second harvests. 



Test II 



This trial was seeded August 11, 1971. It included four New Hampshire 

 experimental synthetics, two of them in both syn 1 and syn 2 generations plus 

 the five varieties 'Blair', 'Carlton', 'Fox', 'Polar', and 'Saratoga', the latter in the 

 syn 1 and syn 3 generation. 



The land was fallowed in 1971 and fertilized with 600 lbs/A of 10-20-10 

 prior to seeding. Seed was broadcast by hand into 5 x 10' plots, with four 

 replicates of each entry. Harvesting and fertilization after establishment was the 

 same as in Test I.
