Responses to selenium in a range beef herd

by Aaron O. Nelson, Robert f. Miller

Abstract

Selenium deficiencies have long been recognized in northern California but only recently in the Central Valley. On the cover, Farm Advisor Aaron Nelson checks the ear tag of a calf roped by ranch owner Clyde Johnson in a study to determine if supplemental selenium would benefit cattle on his Sierra foothill ranch. Results were “remarkable.”

Calves born of cows supplemented with selenium had significantly higher weaning weights.

Improving almond crop forecasts

by Jeffrey Dorfman, Dale Heien

Abstract

Adding May weather data to the state's estimate makes prediction of the California almond crop more accurate.

Wide fluctuations in the California almond crop from year to year complicate marketing strategy. Including early-season weather data could improve the accuracy of crop estimates.

Argentine ant management in cherimoyas

Abstract

Spot application of insecticide kept Argentine ants from disrupting biological mealy bug control.

Effects of changes in the water year on irrigation in the San Joaquin Valley

by Dennis Wichelns, Gerald L. Horner, Richard E. Howitt

Abstract

Growers on a March 1 water year reduced pre-irrigation.

Changing starting date of water contract year to March 1 from January 1 could avoid ‘use it or lose it’ situations

Using concentrate postbloom NAA sprays to thin olives

by William H. Krueger, George C. Martin, Chic Nishijima, John E. Dibble

Abstract

A concentrate spray was as effective as a dilute spray.

Thinning with a concentrate spray was just as effective as with a dilute spray in reducing the crop, improving fruit size and value, and increasing return bloom.

The beet armyworm in floricultural crops

by Harvey A. Yoshida, Michael P. Parrella

Abstract

Wise use of insecticides may be the best defense against this insect.

Common in field and vegetable crops, the beet armyworm has invaded flower crops. It's hard to control with insecticides and can quickly build resistance. Microbial insecticides may be an effective alternative.

Using reclaimed municipal wastewater for irrigation

by Takashi Asano, G. Stuart Pettygrove

Abstract

Experience in communities now using wastewater for irrigation proves it is safe and practical.

The risks are proportional to the degree of human contact and the adequacy and reliability of treatment.

Effect of hydrogen cyanamide on bud emergence in wine grapes

Abstract

Results in earlier, higher budburst in Chardonnay and Cabernet grapes.

Optimal management of saline water tables in irrigated regions

by Timothy K. Gates, Mark E. Grismer

Abstract

A statistical model may help make decisions on salinity and drainage.

A computer model incorporates uncertainties about water tables and aquifers into irrigation management.

Assessment of lateral groundwater flows in the SJV

by Mark E. Grismer, R. Craig Woodring

Abstract

Flows are variable, relatively small, but potentially significant.

Predicting cotton seedling emergence

by Thomas A. Kerby, Mark Keeley, Stephanie Johnson

Abstract

Desirable plant densities can be obtained by basing the seeding rate on predicted heat units and seed quality.

Best stand establishment depends on both warm and cool germination rates of seed as well as temperatures during five days following planting.

Abstract

Control focuses on leafhoppers.

A marketing research approach for improving Extension publications

by Gordon W. Frankie, James I. Grieshop, Carlton S. Koehler, J. Kenneth Grace, Kathleen A. Hesketh

Abstract

A pilot study indicates that market research could be useful in identifying specific consumer information needs.

A two-way exchange of information between producer and ultimate users could lead to more effective publications.
