Goji Berry—a Novel Nutraceutical "Superfruit" for Florida Master Gardeners

Yujie Jiao and Guodong Liu

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 behighly 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.

Pond Apple—A Tree Species Adapted to Salt Stress

Guodong Liu, Yuncong Li, Kimberly Moore, and Kim Gabel

This document provides an overview of the Pond Apple (Annona glabra L.), a semi-deciduous tree native to Florida and Puerto Rico. It highlights the tree’s tolerance to salt and flooding, making it suitable for high-salinity coastal landscapes. The Pond Apple can grow up to 10 feet and produces edible fruit similar to custard apples. Ecologically, it is important as its fruit is consumed by wildlife, and its seeds are dispersed by animals. The tree has various uses, including its edible fruit and medicinal properties, with potential anticancer chemicals. Compared to the bald cypress, it is more salt-tolerant but may suffer from iron deficiency in dry conditions.

Purslane: The Reigning Champion of Vitamins A and E among Vegetables and a Potential Crop for Home Gardens

Xueyan Zhang, Mary Dixon, and Guodong Liu

Purslane is often labeled as a noxious weed in Florida; however, this seemingly pesky plant is perceived as a nutritional powerhouse in Asia and other continents. Levels of vitamin A and E in purslane far surpass those found in broccoli, tomato, and lettuce. A mere 3.5 ounces of purslane can fulfill 81% of an individual's daily vitamin requirements, and up to half a pound can meet the daily needs for both Vitamins A and E. Sustaining this nutritional wealth hinges on the timing of harvest when purslane plants attain a height of 5 to 6 inches. Beyond this stage, purslane becomes excessively fibrous and aged, making it unsuitable for consumption and necessitating removal through weeding. This publication article provides a comprehensive overview of purslane, delving into its botany, garden production, harvest practices, and both culinary and medicinal uses to assist growers and consumers in understanding when to savor its nutritional benefits and when to weed it from farmlands.

Phosphorus Dynamics and Impacts on Potato Production in Northeast Florida

Joris D. Van Zeghbroeck, Guodong (David) Liu, and Yuncong Li

Florida is one of two states (FL and CA) that produce spring potatoes, FL having the highest crop value out of any state in the country ($469.67 per ton). Due to the low phosphorus use efficiency (PUE), high rates of phosphorus (P) are applied to ensure adequate yields. This has led to a buildup of legacy P, resulting in mehlich-1 levels as high as 375 mg kg-1. These levels are significantly higher than the critical values for potatoes (25-35 mg kg-1), yet farmers still report increased yields with P applications. Several organic amendments, management practices, and new fertilizers have been shown to help increase P availability in potato cropping systems by reducing P fixation and maximizing the available P fraction throughout the growing season. New fertilizers and management strategies should be researched in the TCAA to find methods that maintain yields while reducing the environmental impact of potato cropping systems.

Achachairu—a Potential Fruit Crop for Florida

Sergio Gutierrez, Tatiana Sanchez, Zhaohui Tong, and Guodong Liu

Garcinia humilis is an emerging tropical fruit crop in South Florida commonly known as achachairu. Achachairu has attracted much interest as a healthy fruit crop because it is rich in many nutrients such as foliate, vitamins, riboflavin, minerals, and antioxidants. The current use is limited and localized. To help Extension faculty, growers, and students better understand the potential of achachairu (Garcinia humilis (Vahl) CD Adam)  and Garcinia madruno as profitable crops and their health benefits, this publication is synthesized from literature sources and has been networked with farmers, food processors, chefs, and photographers. This document provides an overview of achachairu and ocoro (Garcinia madruno [Kunth] Hammel)—two common species in the Garcinia genus—including cultivation methods and use of the two crops grown in Florida.

A Practical Guide for Adjusting Fertigation Water pH in Specialty Crop Production

Guodong Liu, Md Jahidul Islam Shohag, Lisa Hickey, Yuncong Li, and Shufang Tian

Fruit and vegetable producers have widely adopted fertigation as a common practice. However, achieving optimal nutrient use efficiency and growth of crops requires careful management of the irrigation water’s pH, especially when the water quality exhibits excessive acidity or alkalinity. Adjusting the pH of irrigation water is crucial to meet crop preferences and ensure optimal conditions for growth. Growers frequently encounter challenges in effectively optimizing irrigation water pH. This publication aims to address this issue by providing an overview of adjusting irrigation water pH and offering practical guidelines. The target audiences of this guide are farm/nursery managers, growers, crop advisors, Future Farmers of America (FFA), Extension agents, researchers, students, and others who are interested in crop production.

Symptoms of Nitrogen and Iron Deficiency in Luffa

Qiansheng Li, Marina Gluck, Yanlin Wang, Wendy Mussoline, Qingren Wang, Yuncong Li, and Guodong Liu

Luffa (Luffa aegyptiaca, synonym Luffa cylindrica) is a tropical and subtropical climbing plant belonging to the cucumber family (Cucurbitaceae), natively cultivated in South and Southeast Asia. There are two main species of luffa grown in Florida: smooth luffa (Luffa aegyptiaca Mill.), primarily grown in small gardens and angled luffa (Luffa acutangula (L.) Roxb.), basically grown for commercial production (https://edis.ifas.ufl.edu/publication/HS1285). It is commonly called sponge gourd, Egyptian cucumber, or Vietnamese luffa. Young fruits are edible and rich with nutritional and medicinal value (Partap et al. 2012; Azeez, Bello, and Adedeji et al. 2013). The mature fruit has strong fibrous insides, which can be used as natural porous fiber (Siqueira, Bras, and Dufresne 2010; Sivakandhan et al. 2020) for dishwashing or shower scrubbing. This publication is written for growers, state and county Extension faculty, and students interested in crop production.

Soil pH Management for Optimum Commercial Fruit Production in Florida

Guodong Liu, Rao Mylavarapu, Ed Hanlon, and Wei Chieh Lee

Soil pH is one of the most important soil chemical properties and affects nutrient bioavailability and microbial activity. The purpose of this article is to provide an overview for faculty, crop consultants, crop advisors, fruit growers, and students who are interested in fruit production. The crop response to soil pH varies due to crop genetic diversity. Soil pH determines nutrient bioavailability and hence fruit growth, yield, and quality.

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

Mary Dixon and Guodong Liu

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.

How to Fertigate Plant Vines via Center Pivots for Commercial Potato Production in Florida

Xiangju Fu, Guodong Liu, Lincoln Zotarelli, Steven Sargent, Kati Migliaccio, and Yuncong Li

Potatoes are an important crop in the United States, and Florida is ranked the 7th producer nationwide for potato production. In Florida, potatoes are mainly planted on sandy soils with low nutrient- and water-holding capacities. Nitrogen is the most limiting nutrient in these soils. Adopting efficient fertilization methods such as fertigation is imperative for minimizing leaching and improving use efficiency of nitrogen. This new 12-page article provides step-by-step guidelines for fertigation practices for commercial potato production.
