Long-range dispersal of pink bollworm into the San Joaquin Valley
by Vern Stern, Vahram Sevacherian
| Full text HTML  | PDF  
Late summer storms carry the pink bollworm into the San Joaquin Valley. Cotton growth studies indicate this pest has less potential for damage in the San Joaquin Valley than in the southern desert valleys.
Utilizing irrigated pasture for beef heifers to be bred as yearlings
by John L. Hull, Charles A. Raguse
| Full text HTML  | PDF  
Although irrigated pasture is a good diet, energy supplementation will increase the average daily gain of growing heifers after weaning.All phases of management, genetics, and nutrition must be considered if rearing replacement heifers for early breeding is to be successful.
Ethephon hastens maturation of Thompson Seedless raisin grapes
by Ghazi I. El-Banna, Robert J. Weaver
| Full text HTML  | PDF  
In a study designed to determine whether ungirdled Thompson Seedless grapes ripen faster (as measured by OBrix) as a result of ethephon sprays, it was determined that sugar accumulates earlier in treated grapes.
Energy supplies for milking parlors
by William C. Fairbank, Richard N. Eide, Gale G. Gurtle, Herbert S. Etchegaray
| Full text HTML  | PDF  
A survey of southern San Joaquin Valley dairies, many of which operate 16 to 20 hours a day, shows that few have an adequate standby power system t o carry them through a power outage or fuel interruption of more than a few hours.
Silvicultural treatments to reduce losses to bark beetle
by Jordan Lang, Robert C. Heald, Edward Stone, Donald L. Dahlsten, Robin Akers
| Full text HTML  | PDF  
Using the “aggregation” approach to characterize groups of Ponderosa pines, researchers at the Blodgett Forest Research Station are studying the effects of thinning on beetle-caused mortality.
Rumensin benefits new feedlot calves
by Donald G. Addis, Carol L. Adams
| Full text HTML  | PDF  
A method is discussed for adding Rumensin t o a 72-percent-concentrate receiving ration for newly arrived feedlot replacement calves, without adversely affecting feed consumption, body weight gain, or animal health.
Big vein disease of lettuce in Imperial Valley
by Demetrios G. Kontaxis
| Full text HTML  | PDF  
Only 12 percent of the lettuce plants infected with big vein develop into a marketable crop. A systemic fungicide controls the disease, whereas fumigants appear t o favor big vein of lettuce.
Users place high value on federal-state market news
by James H. Cothern
| Full text HTML  | PDF  
California producers and related agricultural industries use market news to make a variety of marketing decisions, according to a University' of California survey.
Thinning methods influence celery-stalk size
by Norman C. Welch, John W. Inman
| Full text HTML  | PDF  
Size discrepancy in celery at harvest time is costly t o growers. Early thinning results in the most uniform sizes a t harvest and highest yield in weight.
