Artificial breeding of turkeys: Artificial insemination of turkeys requires exacting procedures but does offer specific advantages
by F. W. Lorenz, J. D. Carson
| Full text HTML  | PDF  
Artificial insemination of breeding turkeys seems to offer three specific advantages over natural mating: 1, elimination of the need for saddles and thus of damage to the hens by the toms, 2, fewer males needed, and 3, increased fertility.

Report of long-term research on the avocado: Studies on alternate bearing, varieties, rootstock, propagation and storage by Division of Subtropical Horticulture
by Robert W. Hodgson
| Full text HTML  | PDF  
Erratic bearing behavior and consequent low-average yield of the principal commercial variety of avocado–Fuerte– was noted by growers when the industry was young. It was a matter of general concern, for it was realized that higher yields and more regular production would be necessary to bring this new and strikingly different fruit within the purchasing power of the average consumer and thus permit the development of a commercial orchard industry in southern California.
