Hastings Sweet Corn Variety Trial with Videos

Sweet corn is a commodity that is not currently grown commercially in the Tri-County Agriculture Area, although there were a handful of small growers in the past. The growing conditions are suitable, but the markets are not currently in place. Gary England, former Hastings Agriculture Extension Director, successfully grew sweet corn for years in the Apopka area and he believes that the accessibility to I-95 is an advantage for local growers interested in sweet corn. When harvest time rolls around it would be much easier for transporters to pick up sweet corn from North Florida along the I-95 corridor, rather than driving all the way down to Palm Beach County where most of the sweet corn is grown in Florida. Dr. Wendy Mussoline partnered with UF sweet corn breeder, Dr. Marcio Resende, and the HAEC staff to complete a variety trial on eight different varieties of bi-color, sweet corn. The seed for the trial was donated by four different companies which are highlighted in the table below. In this video https://www.youtube.com/watch?v=rcHPM-Ap4m4 Dr. Resende introduces one of his favorite varieties in regards to taste, texture and harvest yield.

The trial was planted on March 2, 2020 and most of the varieties were harvested on May 18, which was 77 days after planting. One early variety, “Superb”, was harvested 72 days after planting. Dr. Mussoline shows each of the varieties up close, describes the grading standards for sweet corn and discusses her choice variety from the trial in the following video https://www.youtube.com/watch?v=VUbGEse2JWU. Harvest yields among the eight varieties ranged from 324 to 448 crates/A (assuming 48 ears/crate), and the highest yielding varieties were ‘Affection’ (448), ‘BSS-1075’ (419), and ‘Seminole Sweet XR’ (407). The varieties with the highest percentage of ears that graded as U.S. Fancy were ‘Everglades’ (90%), ‘Affection’ (86%) and ‘Superb MXR’ (80%).

Sweet corn is much more finicky about harvest dates than potatoes. Potatoes can be harvested within a two to three- week timeframe (depending on the variety), without compromising their quality. Sweet corn, on the other hand, has a very specific maturity date and narrow harvest window. It needs to be harvested within a 2 to 3-day timeframe to ensure the proper sugar/starch ratio, depth of kernel, uniformity, etc. If it remains too many days in the field after maturity, the sugars begin to turn to starch and the sweet, juicy flavor and tender texture are compromised. Watch the taste test video of our very own Wanda Clegg (Clegg Sod Farm in Bunnell) as she chooses her favorite of four varieties https://www.youtube.com/watch?v=Zyb1GXYm5ig

several bins filled with harvested sweet corn in the field

All of these commercial varieties hold their flavor and texture for weeks after harvest as long as they are refrigerated. This is not the case for some of the older varieties such as “Silverqueen.” After the trial was completed and all the measurements were gathered, the remaining 6000 lbs of sweet corn was donated to L&M Farms and was included in their USDA Farmers to Families Food Box Program – https://blogs.ifas.ufl.edu/news/2020/06/16/farms-deliver-produce-to-local-food-banks-through-usda-coronavirus-food-assistance-program/

Continued efforts will be made to reinvigorate growers in Northeast Florida to grow sweet corn and to establish new market relationships with existing processors in South Georgia.

It was a combination of orange-flesh cultivars that were put in the bags for the contest...we didn't want anyone to have an unfair advantage by only giving one cultivar. If you are interested in seeing all the sweet potato cultivars, we have them in crates at our Extension office...just go by the Putnam County Extension office in East Palatka and ask Kendra to show you...you can grab a couple samples while you are there...enjoy!

Hi Yvonne, I'm really glad to hear that you enjoyed the purples. Your comment reminded me that I need to add the flyer about our local sweet potato pie contest to the blog...will do right now...we are cohosting a contest with Azalea City Brewery located at 120 S. 7th Street in Palatka. The brewery will be giving out your choice of orange or purple sweet potatoes on Thanksgiving weekend and the contest will be on Friday December 3rd...hope you can participate! Thanks for your encouraging comment... Wendy

It's very fast growing and needs very little care. Also wondering if I should stake it up to re-inforce it. I would like to have your e-mail so I can send it to you. Thank you. Judy

Dear Dr. Mussoline: I've noticed a crop that's new to me as I drive from my home 3 miles east of Picolata off CR 208 via 13a to 13 to 207 and on to St Mark's in Palatka where I'm the priest. The crop sort of looks like an Easter Lilly stalk with yellow flowers on the top. It isn't Sunn Hemp, I don't think. Would you tell me what it is? Blessings, Bob Marsh

Hi Michael, The UF/IFAS Putnam County Extension office could normally help you with this, but our offices are currently closed to the public due to COVID-19. At this time, your best bet is to collect your own soil samples and send them to the UF Soils Lab for analyses. They will email you results within a week or so. There is a fee associated with each sample and to determine that fee, you will need to consult the website for the lab to determine what type of soil sample you are submitting. Here is the website https://soilslab.ifas.ufl.edu/ESTL%20Tests.asp Be sure to send in the form with your samples. If you have further questions, please email me directly at wmussoli@ufl.edu

Hi Imre, We cannot recommend specific companies even if I was familiar with the area. However, you can visit: http://www.treesaregood.org/ and find a local certified arborist in your city. Either stump grinding or hack/squirt methods are effective. If it's a large tree though, you'll be better off stump grinding. Be sure to spray or paint on the herbicide immediately after cutting.

Hi, I moved into a house with a beautiful Chinese tallow. I hate to have it taken down, but it spreads like wild fire, the roots are growing under the house, and it is filthy when it sheds. The problem is the cost of removal. I live in Leesburg; do you know of an affordable tree removal service in my area? Also, should I have the stump grinded or just cut and apply herbicide? Thanks, Imre Hocker

We attended a Meat Sheep Alliance in Live Oak on 4-27-19 and learned about your work with sweet potatoes as a supplement for grazing/forage. We live in Callahan, FL (Nassau County) and wish to improve our acidic, clay soil (formerly a pine forest) for our 3 4-acre pastures. Should we plant sweet potatoes in our fields to supplement. We have 32 Katahdin sheep and need to do more rotational grazing and better nutrition. We also have 2 horses. We fight intestinal parasites and need better nutrition. We are trying supplements to our Pensacola Bahia and Tifton 9 pastures. Would this help? Thank you, Jon Hall and Leslie Burke 904-945-9535

Since the camphor tree is not on the Florida noxious weed list, you are not required to remove it. However, many organizations and institutions consider it an invasive species. If having it removed is in your financial budget, sure, have it taken down, but consult a certified arborist first. Sounds like there are several risky factors in your situation that doesn't have an easy, straightforward answer.

STEPHANIE GUTTMAN

We recently moved to a new house in Ocoee. The backyard has a fairly large camphor tree. My granddaughter loves to climb in it and, of course, it provides lovely shade in an otherwise barren backyard. However, I've found it on this invasive species list. It's roots have begun to invade and cause damage to our neighbors' sprinkler system and fence. Should this tree come down and something else be placed in our yard? Please give us advise, as there is some dispute about this in our family and we seek facts. Feel free to email regarding your recommendations.

Hi Edward, The color depends on the variety/cultivar. We normally see red tendrils with vines that produce red grapes, and green tendrils with the rest. In fact, the tendrils are actually aborted flower clusters, which would have otherwise turned into fruits! I have to thank Dr. Sara Spayd from NC State University for assistance with this question. She's an extension viticulturist :)

Hi Cindy. First, thank you for removing an invasive species!! There is still debate on the allelopathic effects of tallow on native vegetation. One paper noted that the tallow contains chemicals that inhibit growth of other plants, while another disproved it, but the study was specific to cypress trees. I'm happy that your lawn has returned. Maybe it just needed a friend to hang out with ;) Thanks for checking in!

Hello Kim! If you don't mind, please send me a photo (pfletch@ufl.edu) of the caterpillars before I make a recommendation. First step of IPM is identification! Also, have you tested your soil nutrients within the past year? If not, go with a low grade fertilizer similar to 6-4-6. We try to avoid fertilizers with a high phosphorus percentage (the middle number) unless your soil is deficient. Leafy greens also benefit from a side dressing of nitrogen, such as ammonium sulfate. Be sure to apply it very conservatively and just outside of the leaves to avoid burning the plant.

Kim Frawley

Hi Prissy, I am seeing small caterpillars on my collards and kale. What is the best option for spraying on leaves I will be eating soon? Also what fertilizer do I use on my leafy greens? Thank you!
