100 Tons of Spineless Cactus Forage Per Acre Per Year. Field Scene at Santa Rosa 



The Annual Yield 



In the summer of 1906 in the coast cli- 

 mate of Sonoma County, California, on 

 the black heavy adobe, a soil thought 

 wholly unsuitable for cactus, there was 

 produced an average of forty-seven and 

 one-half pounds per plant in six months' 

 growth, from single rooted leaves. These 

 yielded 180,230 pounds or over ninety 

 tons of forage per acre. 



One may reasonably expect, under fa- 

 vorable conditions, to obtain a yield up to 

 100 tons of good forage per acre per year. 



The Spineless Opuntias will produce 

 nearly double as much feed the third and 

 succeeding years as they do the second 

 season of planting. 



Of course, it would not be expected 

 that there would be more than one-fourth 

 of the above yield on desert soil without 

 irrigation. Still there could be expected 

 almost twice as much, as mentioned 

 above, where the climate is warm and 

 where there are one or two light irriga- 

 tions each season.
