LADINO WHITE CLOVER 



Material and Methods 



Ladino white clover test # 1, which includes eleven seed lots, was seeded 

 June 4. 1955. on a Charlton soil at Dover. New Hampshire. The land had 

 previously been fertilized in 1954 with 600 lbs. per acre of 5-10-10, ten 

 tons of manure, and three tons of lime. In 1955, two additional tons of 

 lime were applied and 600 lbs. per acre of 8-16-16 at seeding. The design 

 was a split plot with three sub-plots seeded to Ladino alone and three to 

 a Ladino-bromegrass mixture. The clover was seeded at three pounds per 

 acre except for Vermont polyploid, which was seeded at six pounds be- 

 cause of the larger seed size of this strain. Fifteen pounds of bromegrass 

 per acre were seeded in the mixture. 



Two topdressings were made in 1956 and 1957. one in early spring and 

 one after the first harvest. Approximately 500 lbs. per acre of 8-16-16 were 

 applied each time on the mixture and 500 lbs. per acre of 0-15-30 on La- 

 dino alone. 



Ladino white clover test # 2 was seeded May 29, 1956. on a Worthing- 

 ton soil at Colebrook. New Hampshire. Seven strains were seeded at three 

 pounds per acre except for Vermont polyploid which was seeded at five 

 pounds per acre. Three tons of lime were applied per acre at seeding and 

 600 lbs. of 8-16-16. The design was a split plot, with four sub-plots seeded 

 to Ladino alone and four to a Ladino-Fischer bromegrass mixture. The 

 bromegrass was seeded at about 12 pounds per acre. Approximately one 

 bushel of oats per acre was seeded as a companion crop. Fertilization rate 

 during 1957. 1958, and 1959 was approximately 400 pounds per acre 

 of 0-15-30 in the spring and again after the first harvest. 



Ladino white clover test # 3 was seeded June 4, 1957. on an Agawam 

 fine sandy loam at the Strafford County Farm. Dover, New Hampshire. 

 Seven strains were seeded in a split plot arrangement, with three sub-plots 

 to Ladino and three of a Ladino-Saratoga bromegrass mixture. This was 

 a cooperative NE-28 regional study and was also seeded at four other 

 states in the Northeast. The Ladino was seeded at three pounds per acre 

 alone and two pounds in the mixture. The bromegrass was seeded at 10 

 pounds per acre. Plot size w 7 as 5 x 20 feet. 



Fertilization at seeding was one ton of lime per acre I to pH of about 

 6.7) and 600 lbs. of 5-10-10. In 1957. two applications of 0-15-30 were 

 made. 250 lbs. per acre in the spring and again in the (all. 



Results and Discussion 



Results for Ladino test # 1 are given below in Table 5. Excellent 

 stands were obtained (ill these plots when seeded in 1955. Three harvests 

 were made in 1956. but because of extensive drought, only one harvest 

 was possible in 1957. and clover stands were then lost. 



Several lots of Pilgrim white clover I large type) were included, as well 

 as an intermediate type from New Zealand, and Vermont polyploid, a very 

 large type developed by Dr. A. Gersh<>\ at the Universit) of Vermont. Pil- 

 grim white clover was developed for the Northeast, and generally lias pro- 

 duced relatively good yields at this Station. Vermont polyploid produces 

 relatively few stolons, compared to the normal Ladino strains, and stand 

 and \ ields have been somewhat lower. Strains of common white clover,
