Red LaSoda is the red-skinned fresh-market potato standard for Florida. It was observed in 1949 as a deep red mutant of LaSoda in the Louisiana potato breeding program. It has been in trials over many seasons and at many locations in Florida including university and grower sites. Production and quality results provided in this 4-page fact sheet are summarized from the red-skinned fresh-market trials conducted by the University of Florida over the past 14 seasons. Written by Lincoln Zotarelli, Doug Gergela, Chad M. Hutchinson, David Dinkins, and Edsel Redden, and published by the UF Department of Horticultural Sciences, August 2013.

Minimum Number of Soil Moisture Sensors for Monitoring and Irrigation Purposes
Managing soil moisture properly through irrigation is key to increasing crop yield and conserving water. By understanding soil moisture variability, growers can better manage their irrigation systems to apply the right amount of water at the right time. This 4-page fact sheet proposes guidelines for soil moisture sampling that account for spatial variability, which helps to determine the minimum number of soil moisture sensors required to survey and monitor a specific area for irrigation. Written by Lincoln Zotarelli, Michael D. Dukes, and Marcelo Paranhos, and published by the UF Department of Horticultural Sciences, July 2013.

Trastornos fisiologicos de la papa: Necrosis por calor interno
La necrosis por calor interno (NCI) es un trastorno fisiológico que causa un pardeamiento inaceptable del tejido del tubrculo y puede causar pérdidas económicas para el productor. Las tres principales causas de la NCI en los tubérculos es la alta temperatura en el suelo, la humedad inadecuada del suelo y la nutrición sub-óptima de la planta, o la combinación de estos factores.

Growing Potatoes in the Florida Home Garden (HS993/HS183)
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 9-page fact sheet was written by Christian T. Christensen, Libby R. Rens, Jeffrey E. Pack, Lincoln Zotarelli, Chad Hutchinson, Wendy Dahl, Doug Gergela, and James M. White, and published by the UF Department of Horticultural Sciences, April 2013.

Subsurface Drip Irrigation (SDI) for Enhanced Water Distribution: SDI – Seepage Hybrid System (HS1217)
In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high water tables are one of the most inefficient methods of irrigation, though some irrigation management practices can contribute to better soil moisture uniformity. Subsurface drip irrigation systems apply water below the soil surface by microirrigation, improving the water distribution and time required to raise the water table for seepage irrigation. This 6-page fact sheet was written by Lincoln Zotarelli, Libby Rens, Charles Barrett, Daniel J. Cantliffe, Michael D. Dukes, Mark Clark, and Steven Lands, and published by the UF Department of Horticultural Sciences, March 2013.

Trastornos fisiologicos de la papa: Centro marron y Corazon hueco (HS1214)
El centro marrón y el corazón hueco son trastornos fisiológicos internos no-infecciosos del tubérculo de la papa. Un centro marrón (también llamado corazón incipiente y hueco, corazón marrón o centro de azúcar) se caracteriza por una región muerta en las células de la médula de los tubérculos lo que resulta en un tejido de color marrón.

Manejo de malezas en las papas (HS1213)
Las malezas causan problemas en la producción de patata en Florida y puede reducir rendimientos a través de competencia directa por la luz, la humedad y los nutrientes, o por albergar insectos y enfermedades que atacan las patatas.

Trastornos fisiologicos de la papa: Grietas de Crecimiento (HS1211)
Las grietas de crecimiento son un trastorno fisiológigo externo no infeccioso del tubérculo de la papa en el que el tubérculo se agrieta durante el crecimiento. La bendidura se cura, pero deja una fisura en el tubérculo. This 3-page fact sheet was written by L. Zotarelli, C. Hutchinson, S. Byrd, D. Gergela, y D. L.

Agricultural Management Options for Climate Variability and Change: Microirrigation (HS1203)
Microirrigation is the slow, frequent application of water directly to relatively small areas adjacent to individual plants through emitters placed along a water delivery line. A leading advantage of microirrigation is that evaporation that does not contribute to plant growth much less than with sprinkler irrigation.

Potato Physiological Disorders – Brown Center and Hollow Heart (HS945/HS197)
Brown center and hollow heart are internal noninfectious physiological disorders of the potato tuber. Brown center is characterized by a region of cell death in the pith of the tuber that results in brown tissue. Hollow heart is characterized by a star- or lens-shaped hollow in the center of the tuber This 2-page fact sheet was written by L. Zotarelli, C. Hutchinson, S. Byrd, D. Gergela, and D. L. Rowland, and published by the UF Department of Horticultural Sciences, May 2012.

Potato Physiological Disorders – Growth Cracks (HS930/HS182)
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. Zotarelli, C. Hutchinson, S. Byrd, D. Gergela, and D. L. Rowland, and published by the UF Department of Horticultural Sciences, May 2012.
