Comparative experimental seedings to pellets and 

 seedings to nonpelleted seed 



Six }^o-acre experimental plots — 3 hand- 

 broadcast to pellets; 3 to nonpelleted 

 seed. 



Nonpelleted seed airplane broadcast on 

 66 acres; 35 acres plowed and drilled! 

 1 acre burned and drilled. Two ex- 

 perimental areas (63 plots). 2 



Nonpelleted seed airplane broadcast on 

 60 acres; 120 acres plowed and drilled; 

 360 acres burned and drilled. One 

 experimental area (41 plots) . 2 



Nonpelleted seed airplane broadcast on 

 1,470 acres and drilled on 417 acres. 

 One experimental area (36 plots). 2 



Nonpelleted seed airplane broadcast on 

 2,350 acres; 850 acres burned and 

 drilled and 922 acres plowed and 

 broadcast to nonpelleted seed by 

 spreader. Two experimental areas 

 (69 plots) . 2 



Nonpelleted seed airplane broadcast on 

 750 acres. 



Nonpelleted seed airplane broadcast on 

 1,175 acres of plowed seedbed; 655 

 acres of unprepared seedbed; and 

 broadcast by spreader on 1,200 acres 

 of plowed seedbed. Two experi- 

 mental areas (69 plots). 2 



2 Each area was divided into 3 strips — burned, plowed, and not treated; 11 

 seeding methods on each strip. 



San Carlos Indian Reservation, Arizona 



The San Carlos Indian Reservation in Arizona was seeded at two 

 locations — 2,500 acres in the Paymaster area and 17,500 acres on the 

 Ash Creek Ranch. Seedings were in the desert-foothill grass type of 

 vegetation at an elevation of 4,500 feet. 



Procedures 



Large-scale seeding. — Seeding was done between August and 

 October 1946 on unprepared seedbeds. Both areas were sown by air- 

 plane to compressed pellets containing seeds of sand dropseed and 

 Lehmann and weeping lovegrasses at a ratio of 33 : 16 : 1. Seeding was 

 at the rate of one pellet per square foot with six to eight seeds per pellet. 



Experimental field seeding. — At Ash Creek, 28 acres were
