Métodos para el establecimiento de trasplantes de fresa en Florida

Florida es el segundo productor de fresa más grade de los Estados Unidos, con un valor estimado de $337 millones. La siembra inicia entre finales de septiembre y mediados de octubre, en momentos donde las altas temperaturas representan un reto significativo para la sobrevivencia de los trasplantes, y por tanto también para el rendimiento y la calidad. El propósito principal de esta publicación es proporcionar recomendaciones basadas en resultados de investigación sobre métodos de establecimientos de trasplantes para productores de fresas en la Florida.

Methods for Strawberry Transplant Establishment in Florida

Florida is the second largest strawberry producer in the United States, with an annual farm gate value of about $300 million. Planting occurs from late September through late October, and high air temperatures pose significant challenges for transplant establishment and thus yield and fruit quality. The primary purpose of this new 4-page publication of the UF/IFAS Horticultural Sciences Department is to provide research-based recommendations on transplant establishment methods for strawberry growers in Florida. The techniques presented are overhead irrigation application methods and practices, strawberry plugs and bare-root transplants, crop protectants, and reflective mulching. Written by Emmanuel Torres-Quezada, Lincoln Zotarelli, Vance M. Whitaker, and Shinsuke Agehara.

Tomato Production in Florida Using Fertigation Technology

Tomato is in high demand because of its taste and health benefits. In Florida, tomato is the number one vegetable crop in terms of both acreage and value. Because of its high value and wide acreage, it is important for tomato production to be efficient in its water and nutrient use, which may be improved through fertigation practices. Therefore, the objective of this new 7-page article is to disseminate research-based methods of tomato production utilizing fertigation to enhance yield and nutrient use efficiency. Written by Mary Dixon and Guodong Liu, and published by the UF/IFAS Horticultural Sciences Department.

Goji Berry: a Novel Nutraceutical “Superfruit” for Florida Master Gardeners

Goji berries have been used in both fresh and processed forms for food and medicine for more than 4,000 years in China. The goji berry fruit is known as a “superfruit” thanks to its high levels of vitamins and minerals, as well as other medicinal benefits recognized in many countries around the world. Most of Florida’s climate is favorable for goji berry, and a few Florida growers have cultivated it for years. This species can tolerate infertile and unfavorable growth conditions, and the prominent health benefits of this crop may be highly profitable for Florida growers. The objective of this new 7-page article is to provide a general overview of how the goji berry can be grown in Florida. Written by Yujie Jiao and Guodong Liu, and published by the UF/IFAS Horticultural Sciences Department.

Leek Cultivation Guide for Florida

Leek (Allium porrum L.) is a member of Amaryllidaceae, a family with ornamental crops, like amaryllis, and with vegetable crops, like onion. Leek is a highly demanded vegetable because of its flavor and nutrient content. Although there is great potential for leek to be grown commercially in Florida due to demand and appropriate climatic conditions, the United States does not currently produce a significant quantity of leek compared to countries such as Indonesia, Turkey, and China. This new 7-page publication of the UF/IFAS Horticultural Sciences Department, written by Mary Dixon and Guodong Liu, provides a basic guide to cultivation of leek in Florida, as well as information on its agricultural, culinary, and medicinal uses.

Cultivares de Caqui Japonés en Florida

El caqui japonés, Diospyros kaki L., es originario de China y fue cultivado por primera vez en Florida en el año 1870. El número de fincas productoras de caqui en Florida ha aumentado de 164 a 227 durante el período 2012-2017, haciendo mayor hincapié en la naturaleza de pequeña escala de la superficie promedio de fincas en esta industria. Los árboles crecen y fructifican mejor en el centro y norte de Florida, y pueden producir altos rendimientos de fruta de buena calidad. En el sur de Florida, la calidad de los frutos de tipo astringentes es mejor que la de los de tipo no astringentes.

Summer Pruning in Low-Chill Peaches Grown in Florida

Low-chill peach trees growing under Florida conditions can become vigorous and large. Summer pruning is a management strategy that can be applied to help restructure the canopy, direct the tree’s resources into fruit production, and improve the efficiency of fieldwork. Without summer pruning, peach orchards in subtropical regions will continue to grow vigorously and, if left unmanaged, will reach a point at which ladders will be required to harvest and maintain the trees. Summer pruning can be a means of reducing overall tree size, redistributing fruiting wood for easier harvesting, reducing disease pressure, and increasing fruit quality. This new 5-page publication of the UF/IFAS Horticultural Sciences Department, written by Ali Sarkhosh, Dustin Huff, Trequan McGee, and Juanita Popenoe, provides an illustrated step-by-step guide to summer pruning of peach trees.

Fusarium Wilt: A New Threat to Florida Lettuce Production

Fusarium wilt of lettuce is a disease caused by the fungus Fusarium oxysporum f.sp. lactucae. The disease is present in all lettuce production areas worldwide. Recently this disease has been identified in Florida in localized fields. This new 4-page publication of the UF/IFAS Horticultural Sciences Department presents information about the disease, symptoms, and control measures useful to lettuce growers in Florida. Following these recommendations may help to avoid the spread of this fungus in muck soils at the Everglades Agricultural Area (EAA), where 90% of the lettuce in Florida is planted.

How to Measure Leaf Disease Damage Using Image Analysis in ImageJ

This new 13-page article introduces simple image processing and analysis techniques to quantify leaf disease damage using ImageJ, an open-source image processing program. These techniques are not meant to replace crop scouting or disease diagnosis by a plant diagnostic laboratory, but rather to provide a supplemental tool for making quantitative measurements of leaf disease damage. Similar techniques are also available for plant growth assessment, including plant height, plant width, and canopy cover area. The image processing and analysis techniques introduced in this article are fairly simple to use and thus can be adopted not only by researchers, but also by producers, crop consultants, Extension agents, and students. Written by Lillian Pride, Gary Vallad, and Shinsuke Agehara, and published by the UF/IFAS Horticultural Sciences Department.

Implementing the Five Rs of Nutrient Stewardship for Fertigation in Florida’s Vegetable Production

The five Rs of nutrient stewardship is a mnemonic device used to emphasize accuracy and precision for nutrient management so as to apply the (1) right source of fertilizer at the (2) right rate at the (3) right time in the (4) right place with the (5) right irrigation. Because the majority of Florida’s soils are sandy, this fifth R is imperative for sustainable nutrient management for commercial crop production. These main points of nutrient management (source, rate, time, place, irrigation) may help enhance sustainability by reducing pollution by eutrophication, nitrogen loss through ammonia volatilization, and climate change from soil greenhouse gas emission. This new 8-page publication of the UF/IFAS Horticultural Sciences Department was written by Mary Dixon and Guodong Liu.

Irrigation System Descriptions for Tropical and Subtropical Fruit Crops in Florida

Florida’s tropical and subtropical fruit crop industries use various irrigation systems, including high-volume systems designed for irrigation and freeze protection, drip systems for herbaceous fruit crops (papaya, banana), and microsprinkler types, mainly for irrigation and fertigation. There continues to be a steady stream of potential tropical and subtropical fruit producers in Florida, many with little to no knowledge of the various types or purposes of various irrigation system that have been used successfully for the past 60 years. This new 9-page publication of the UF/IFAS Horticultural Sciences Department includes potential producers, Extension faculty and agents, and irrigation companies.
