All Issues

The red sport of the Delicious apple most commonly planted in California is Starking. Richared Delicious has been planted on only a limited acreage since it colors later than Starking. The popularity of Starking has declined, however, because many trees or parts of trees have reverted toward the parent Delicious type and produce fruit less highly colored. Reverted fruit appears distinctly striped. Though lighter red, the stripes are prominent on reverted fruit because of the lack of the characteristic red background of the normal Starking. The reverted Starking is often called Stripes, or Common Delicious, as opposed to Double-red for well-colored fruit.

Studies conducted for three years, with several varieties of olives, were designed to determine the stage of fruit maturity at harvest that would result in the highest quality of black-ripe and green-ripe processed fruit.

Great Lakes lettuce, adapted to culture under a range of environmental conditions, normally produces a medium-large, globular, semi-exposed head. In some plantings, however, a percentage of the plant population develops conical-shaped heads, with the wrapper leaves or head leaves in a spiral-like fold. Market-stage plants of this type are generally referred to as spiraled heads. The shipper and retailer prefer a slightly oblate head with broad, flat butt, which can be packed evenly and firmly.

Alfalfa stands in the Imperial and Palo Verde valleys of southern California often need to be replanted each year.

The value of alfalfa meal as a source of energy for swine was determined for three levels of meal–5%, 20%, and 40% of the ration; three stages of plant maturity–16% bud, 3% bloom, and 34% bloom; and three methods of preparation–suncured, dehydrated, and pelleted dehydrated, reground.

Brown dog ticks have become resistant to a number of the standard insecticides. Pet owners, veterinarians, and kennel operators have asked for new compounds for tick control.
