California Agriculture, Vol. 42, No.1

Feeding dairy goats
Cover:  Sales of goat cheese and other goat milk products are increasing, and some former dairy cow owners are shifting to goat dairies. A survey showed that profitability can be improved by utilizing low-cost agricultural by-products in goat rations.
January-February 1988
Volume 42, Number 1

Evaporation pond seepage
by Mark E. Grismer, Blake L. McCullough-Sanden
| Full text HTML  | PDF  
Seepage from drainage water evaporation ponds declines substantially with time.
Rates of seepage from operating evaporation ponds decline substantially as they age and as salinity increases
New clues in understanding Pierce's disease
by Paul H. Goodwin, Carole P. Meredith
| Full text HTML  | PDF  
Knowledge of the role of water stress in the disease could help in development of resistant grape varieties.
The discovery that water stress is associated with Pierce's disease may be useful in developing new resistant varieties
Feeding California's dairy goats

Sales of goat cheese and other goat milk products are increasing, and some former dairy cow owners are shifting to goat dairies. A survey showed that profitability can be improved by utilizing low-cost agricultural by-products in goat rations.
A survey of producer practices showed that dairy goat operations could lower costs by incorporating crop by-products into rations
The economic effects of salinity and drainage problems
by Dennis Wichelns, Richard E. Howitt, Gerald L. Horner, Daniel Nelson
| Full text HTML  | PDF  
A study of crop yields and acreages suggests that recycling drain water may be only a temporary solution.
Cropping patterns and yields change markedly
A comparison of bench-top and perimeter heating of greenhouses
by Bryan M. Jenkins, Roy M. Sachs, Glen W. Forister
| Full text HTML  | PDF  
Bench-top heating uses less energy than perimeter heating, but temperature distribution in the plant canopy and soil require further study.
In search of low-maintenance turf
by Lin Wu, M. Ali Harivandi
| Full text HTML  | PDF  
Several candidates passed the first tests under reduced irrigation, fertilization, and mowing.
Several species show promise
The biological consequences of selenium in aquatic ecosystems
by Elizabeth A. Davis, Kurt J. Maier, Allen W. Knight

| Full text HTML  | PDF  
A regular preharvest defoliant plus pyrethroids was effective against SPWF.
Combining a defoliant with an insecticide gave superior control of sweetpotato whitefly in cotton
Biological control of variegated leafhopper in grapes
by D. González, V. Cervenka, M. Moratorio, C. Pickett, Lloyd T. Wilson
| Full text HTML  | PDF  
Effective parasites of this new pest of San Joaquin Valley grapes are being sought for use in IPM programs.
Long-term control of variegated leafhopper in grape IPM programs will depend on finding, rearing, and releasing effective natural enemies
Managing cabbage aphids in brussels sprouts
by Carolyn Pickel, Frank G. Zalom, Norman C. Welch

Control sprays can be reduced without affecting yield or quality.
The obliquebanded leafroller: A new pest in pistachios?
by Richard E. Rice, Donald L. Flaherty, Richard A. Jones
| Full text HTML  | PDF  
Populations have developed in some California pistachio orchards, but OBLR's pest potential is uncertain.
Trapping studies failed to establish pest status
Range weather: A comparison at three California range research stations
by Melvin R. George, Kent Olson, John W. Menke
| Full text HTML  | PDF  
Computerized analysis of weather affecting seasonal forage growth can be useful to livestock producers.
Knowing when to expect the first rain in the fall and the length of winter can reduce risk in livestock operations
