In cooperation with Georgia Organics and faculty with the University of Georgia and Clemson University, we are planning a twilight field day for Thursday July 7, 2005. The field day will be held at the Vidalia Onion and Vegetable Research Center in Lyons, Ga., from 5:30-7:30 p.m. This will give folks an opportunity to visit our field plots and have supper with us after the heat of the day.
We have a compost demonstration in cooperation with the Department of Corrections using poultry litter and municipal yard waste (tree limbs, grass clippings, leaves, etc.). We have both turned and unturned compost piles to show the difference between them.
In addition, we have put in demonstration plots using no-till production with a roller crimper, regular black plastic and biodegradable black plastic. We have planted cantaloupe, cucumber and watermelon into all three systems.
Finally, we are conducting our seed increase with our new pumpkin variety, which we hope to have available in 2006. They should about be ready for harvest and visitors will get a good idea of their potential.
Please make an effort for yourself and encourage your growers and other interested parties to come join us. We will have a sponsored supper followed by visits to the field plots.
I have finally completed compiling the results of the Vidalia onion variety trial. This year was the largest trial we have ever conducted, with 49 entries from 9 different seed companies. This season, the harvest was later than in past years, with a cool spring. We did not harvest our earliest onions until April 25, and the final harvest occurred on May 23. As in the past, many entries in the later harvested onions had problems with sour skin and slippery skin. To combat this problem, we did not use heat curing with the last two harvests.
The field yield ranged from 570 50-lb bags/acre for Var. No. 34140 to 1,233 50-lb bags/acre for SR 1001. Jumbos (>3 in.) ranged from 445 40-lb boxes/acre for HSX-61304 F-1 to 1,214 40-lb boxes/acre for 33076.
Overall, this was a good year for seedstems (there weren't many for most varieties). Sweet Vidalia had the worst problem with seedstems of all the varieties. Doubles, on the other hand, were a significant problem for several varieties.
