Cooperative Unit Systems: 1. Introduction and Raising Market Animals in a Group Setting

Traditionally, organizations such as 4-H have encouraged youth to participate in market animal projects as a way of increasing youth participation and introducing youth to production agriculture. As the demographics shift to a more urban clientele base for 4-H, there are new barriers of entry to market animal projects that were not seen in generations past. To address these barriers of entry, systems such as cooperative animal units have been set up. This 3-page document discusses components and limitations of cooperative animal units. Written by Alyssa Schortinghouse, and published by the UF/IFAS 4-H Youth Development Department, August 2020.

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.

Lumpy jaw is a deer health problem that all deer farmers eventually face. It gets its name from the swollen jaws or cheeks and necrotic lesions it causes in and around the jaw bones of animals including white-tailed deer. The disease is considered a significant problem for deer farms in North America, where it is one of the most important production-limiting diseases and causes high rates of mortality in fawns. This 4-page fact sheet written by Juan M. Campos Krauer, Samantha M. Wisely, and Hannah M. Barber and published by the UF/IFAS Department of Wildlife Ecology and Conservation explains how deer acquire lumpy jaw, how to spot it in deer, how to treat it, and how to prevent it in the first place.

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.

Concepts, History, Principles, and Application of Germplasm Cryopreservation Technology

Germplasm refers to the living genetic resource of such biological materials as seeds, pollen, animal sperm, eggs, embryos, and larvae. Cryopreservation maintains these materials at extremely low temperatures. The technology is used in medicine as well as to maintain biological diversity, preserve genetic resources, support breeding programs, and conserve endangered species. This 10-page fact sheet written by Huiping Yang and Terrence R. Tiersch and published by the UF/IFAS School of Forest Resources and Conservation Program in Fisheries and Aquatic Sciences introduces the basic concepts, history, principles, and applications of germplasm cryopreservation technology.

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.

Pestalotia Leaf Spot and Fruit Rot of Strawberry

Pestalotiopsis-like fungi cause diseases on many different species of plants worldwide, including strawberry. The pathogen is not necessarily new to strawberry and was first reported causing fruit rot in Florida and Israel in the 1970s. However, during the 2018–19 and 2019–20 strawberry seasons, severe and unprecedented outbreaks were reported in Florida, characterized by symptoms on nearly all plant parts including roots, crowns, petioles, fruit, and leaves. This new 4-page publication of the UF/IFAS Plant Pathology Department describes the disease and its causal agent and briefly covers what is known about disease development and control practices. This document will provide valuable information to strawberry nursery and fruit production growers. Written by Juliana S. Baggio and Natalia A. Peres.
