The 11th annual Desert Vegetable Crop Workshop is scheduled for Dec. 6 at the Yuma Convention Center, Yuma, Ariz.

It is being sponsored by the University of Arizona, University of California, Western Farm Press and Western Growers Association and will feature 15 presentations.

Registration begins at 7:30 a.m. with the first presentation at 8 a.m. The workshop is free, including lunch.

Kai Umeda, University of Arizona area Cooperative Extension agent and program chairman, said the program has been moved later into the vegetable season and the program more tailored to production.

“Last year we focused on marketing. This year we are focusing on production topics and as such have applied for four hours of continuing education credit,” said Umeda.

Last year's workshop was held in November and included a trade show.

“We decided to forgo the trade show this year in deference to the downturn in the agricultural economy,” said Western Farm Press publisher Michael Gonitzke. “However, many of those who participated in last year's expo are supporting this year's expo with their financial support to cover the expenses of the conference, particularly lunch.”

“The challenges in desert vegetable production have never been greater and we think the topics on our program this year will aid in producers and others meeting those challenges,” said Umeda.

Forklift rodeo

This year's workshop will once again feature the very popular forklift rodeo. Once again Western Growers Association is sponsoring this competition, which will be held in the convention center parking lot immediately after lunch.

Following is a program outline and pre-registration is available on this page as well. Registration also will be possible at the door.
