PELLET SEEDING ON WESTERN RAXGELAXDS 25 



but there are several other brush species. Major understory species 

 are streambank wheatgrass, Sandberg bluegrass, Nevada bluegrass, 

 and needle-and-thread. In this area, dry farming is successful and 

 good stands of crested wheatgrass have resulted from past range 

 seedings. 



Procedures 



During the fall of 1954 Portneuf had many and varied treatments 

 on 3,355 acres as follows: 325 acres were plowed and coated seed 

 pellets of intermediate wheatgrass were airplane broadcast at 1, 2%, 

 or 6 pounds of seed per acre; 1,175 acres were plowed and nonpelleted 

 seed of intermediate wheatgrass was airplane broadcast on 525 acres 

 and crested wheatgrass on 650 acres. Both species were sown at a 

 rate of 6 pounds per acre. Intermediate wheatgrass seed was air- 

 plane broadcast at 6 pounds per acre on 655 acres with no seedbed 

 preparation. Crested wheatgrass was broadcast by spreader on a 

 plowed seedbed at 7 pounds per acre on 1,200 acres. 



Results 



All treatments on this seeding failed. Within these large seedings 

 the experimental plots that were plowed and drilled produced good 

 stands. 



Experimental Seedings 



Eight experimental seedings of coated seed pellets were made within 

 five large-scale seedings, as follows: Summit, two areas; Dubois: 

 Sand area; Buckskin, two areas; and Portneuf, two areas. Site 

 descriptions were given under the large-scale seedings. 



Procedures 



Each 4-acre experimental area was divided into three strips: one 

 was plowed, one burned, and one not treated. The plots wore seeded 

 at right angles to the 3 strips by an average of 11 seeding methods. 

 Seeding methods included airplane and hand broadcasting o\ seed and 

 two types of coated seed pellets at different rates and drilling at 

 different rates. In general, crested wheatgrass was used on all except 

 the two Portneuf areas, where intermediate wheatgrass was used. 

 Plowing, drilling, and broadcasting were done in November 1954 

 (figs. 6 and 7).
