Seed Piece Spacing Adjustment for Florida Chipping Potato

Seed spacing directly affects crop revenue because the number of potato seeds planted determines the final plant population density. The analysis presented in this 5-page publication was extracted from a series of field trials that looked at improved potato plant arrangement in the field by adjusting seed piece spacing for Florida growing conditions. Written by Fernanda Souza Krupek, Steven A. Sargent, Peter J. Dittmar, and Lincoln Zotarelli and published by the UF/IFAS Horticultural Sciences Department, May 2018.

Creciendo Papas en el Jardín de su Hogar en la Florida

Pick any vegetable crop - from lettuce and tomatoes to peppers and potatoes - chances are IFAS research is helping Florida farmers produce a superior product for consumers in todays copetitive marketplace.
The Irish potato is a cool-season crop. A recently grown and harvested potato exhibits different flavor profiles from one that has been in storage or on a grocery shelf for an extended period. For example, in storage, the starches in potatoes convert to sugars, resulting in a less desirable texture and taste. “New” potato flavor can be achieved in the home garden by following a few growing recommendations. This is ten-page fact sheet is the Spanish language version of HS933 Growing Potatoes in the Florida Home Garden. Written by Christian T. Christensen, Joel Reyes-Cabrera, Lincoln Zotarelli, Wendy J. Dahl, Doug Gergela, Jeffery E. Pack, James M. White, and Chad M. Hutchinson.

Potato Vine Killing or Desiccation

Pick any vegetable crop - from lettuce and tomatoes to peppers and potatoes - chances are IFAS research is helping Florida farmers produce a superior product for consumers in todays copetitive marketplace.
Proper tuber maturity at harvest is an important factor in producing high-quality fresh-market potatoes. Tuber maturity is generally recognized as an important determinant of storage ability and cooking quality. Maturation can be artificially induced by killing the potato vines prior to harvest. This will benefit tuber appearance, limit tuber size, and improve tuber release from the vine. This four-page fact sheet describes the importance of tuber maturation, potato vine killing timing and available methods, and how to determine when to vine kill and when to harvest after vine kill. Written by Lincoln Zotarelli, Steven Sargent, Peter Dittmar, and Mildred Makani, and published by the Horticultural Sciences Department.

Candidatus Liberibacter solanacearum”: An Emerging Pathogen Infecting Potato and Tomato

Fruit deformation of a tomato plant infected with Ca. L. solanacearum
A bacterium called “Candidatus Liberibacter solanacearum” infects potatoes and tomatoes, causing zebra chip in potatoes and psyllid yellows in tomatoes. These disease are highly destructive and have been known to reduce yields by up to 85%. “Ca. L. solanacearum” has been reported in several states, though it has not been detected in Florida, which is the second largest producer of tomatoes and seventh largest producer of potatoes in the US. This 9-page fact sheet covers the biology, distribution, symptoms, transmission, diagnosis, and management of the pathogen and its associated diseases. Written by Binoy Babu, Mathews L. Paret, Nicholas Dufault, and Carrie L. Harmon, and published by the UF Department of Plant Pathology, August 2015.

Growth Stages and Tuber Development of FL1867 Potato under Full and Reduced Irrigation Scheduling

Figure 1. Whole plant samples of FL 1867 during the 2012 growing season at 41 DAP (A), 48 DAP (B), 54 DAP (C), 61 DAP (D), 75 DAP (E), and 90 DAP (F).The potato cultivar ‘Frito Lay 1867’ (‘FL 1867’) is a popular chipping variety grown across Florida and the southern United States. Knowledge of the timing and duration of the tuber initiation and tuber bulking stages for ‘FL 1867’ is critical for timing fertilizer and irrigation applications. So to evaluate the start and length of the tuber initiation and tuber bulking stages under Florida growing conditions, ‘FL 1867’ plants were dug up and photographed on a weekly basis from a commercial field near Live Oak, FL in 2012. This 3-page fact sheet was written by Seth A. Byrd, Diane L. Rowland, and Lincoln Zotarelli, and published by the UF Department of Agronomy, September 2014.

Potato Physiological Disorders – Growth Cracks (HS930/HS182)

ure 1.  Moderate (left) and severe (right) growth cracks in 'Atlantic'Growth cracking is an external noninfectious physiological disorder of the potato tuber in which the tuber splits while growing. The split heals but leaves a fissure in the tuber. Growth cracks generally start at the bud or apical end of the potato and can extend lengthwise. They vary in severity from a surface abrasion to a split through the tuber, depending on the stage of growth during which the initial cracking occurred This 2-page fact sheet was written by L.
