Xarragansett alfalfa produced significantly more forage than any of 

 the other five varieties in 1952 as it did in 1951. Atlantic alfalfa has yielded 

 well for both seasons whereas Ranger yielded well in 1951 hut not in 1952. 



\'ields were obtained on 25 polycross progenies and 6 New York 

 synthetic-bromegrass strains. Yields of the synthetics were better than 

 for the polycross progenies, as expected. Three of the synthetics produced 

 from 600 to 1.100 pounds more dry matter per acre than Lincoln, the 

 lietter of the two clieck varieties. 



Observations were made in 1952 on about 2.000 bromegrass plants 

 with regard to reaction to brown leaf spot, vigor, leafiness, and spread. 

 Self- and open-pollinated seed was collected from desirable plants and 

 grown in the greenhouse in the winter. Progenies were transplanted to 

 the field in the spring. About 300 selected plants were brought into the 

 greenhouse during the winter for production of selfed and crossed seed. 

 About 15 species of bromegrass. chiefly from South America, have been 

 grown in the greenhouse and were transplanted to the field in the spring. 

 These species will be evaluated for leaf spot resistance and other character- 

 istics which might be used in crosses to improve smooth bromegrass. 



The bromegrass breeding nursery will be increased to include about 

 v\500 plants representing 85 strains- 



Approximately 800 ladino plants were inoculated with the crown-rot 

 organism during the winter. Plants showing resistance will be transplanted 

 to the field for further observation. 



A breeding nursery of approximately 2,400 plants, representing 60 

 strains of ladino clover, will be established.

New Hampshire Perennial Red Clover 



Additional Breeder's seed has l)een obtained by hand pollination and 

 through pollination by bees in the greenhouse from plants that have never 

 been grown outside the greenhouse. The plants which furnished the seed are 

 now from one to two and three years old. There is indication that the New* 

 Hampshire Red Clover will persist longer than two years in the green- 

 house as well as in the field. 



A small amount of seed was in a small field plot. This seed will be 

 used in the 1953 replicated field trials along with the new Breeder's seed. 

 Kenland. Pennscott, and other new red clover strains. Unfortunately, there 

 is not enough seed to fill requests from other experiment stations for fur- 

 ther testing. Already, favorable reports of the New Hampshire Perennial 

 Red Clover's persistance has been received from outside New Hampshire. 

 Another attempt will l)e made to increase the seed supply so that the New- 

 Hampshire Red Clover can be entered in the necessary trials to prove its 

 worth.

Split Application of Potash Better for Ladino Clover 



Results obtained in 1952 indicate that greater mid-summer yields of 

 kidino clover can be secured without sacrificing early summer yields if 

 part of the potash fertilizer is applied in the spring and part after the first 

 harvest.
