Emmanuel A. Torres-Quezada, Lincoln Zotarelli, Vance M. Whitaker, andShinsuke Agehara
translated_by Ricardo Gandini-Taveras

Florida es el segundo productor de fresas más grade de los Estados Unidos, y la siembra inicia entre finales de septiembre y mediados de octubre, meses donde las altas temperaturas representan un reto significativo para la sobrevivencia de los trasplantes, y por tanto también para el rendimiento y la calidad de las fresas. Tradicionalmente, un alto volumen de agua es necesario para asegurar el establecimiento apropiado de las plantas de fresas. El propósito principal de esta publicación es proporcionar recomendaciones basadas en resultados científicos, a productores de fresas en la Florida sobre métodos de establecimientos de trasplantes.

Protected Culture for Vegetable and Small Fruit Crops: Types of Structures

Shinsuke Agehara, Gary Vallad, andEmmanuel A. Torres-Quezada

A protective structure is defined as any structure designed to modify the environment in which plants are grown. Protective structures, such as greenhouses, screen houses, and tunnels, are known worldwide as production systems for high-quality vegetable and fruit crops.

Fertilization of Strawberries in Florida

Shinsuke Agehara andGeorge Hochmuth

Strawberry is an important crop in Florida, produced as an annual crop on plastic-mulched beds with drip irrigation. The main production area is in west-central Florida, including Hillsborough, Polk, and Manatee counties. Fertilizer is becoming a more significant portion of strawberry production costs, hence, proper fertilizer management is important for minimizing production costs and maximizing yield and fruit quality, while minimizing potential negative impacts on the environment caused by leaching or runoff of excess fertilizer nutrients. This guide summarizes the recent history of strawberry fertilization research and presents the updated research-based fertilizer management recommendations for strawberry production in Florida.

Managing Spider Mites in Florida Hops

Hugh Smith and Shinsuke Agehara

This publication is designed to provide information on managing spider mites on hops grown in Florida to hops growers, UF/IFAS Extension agents, and other crop protection professionals. Hops (Humulus lupulus L.) (Cannabinaceae), a new crop for Florida, has been studied at the UF/IFAS Gulf Coast Research and Education Center (GCREC) since 2016. A fall and spring crop have been cultivated each year, providing opportunity to observe pests and evaluate pest management strategies over several seasons. Spider mites (Trombidiformes: Tetranychidae) have been a consistent pest of hops at GCREC each season. Information on chemical and biological control is provided.

Using Supplemental Lighting to Grow Hemp in Florida

Johan Desaeger, Shinsuke Agehara, andJacqueline Coburn

With the removal of hemp from the controlled substances list, hemp is now one of the emerging crops in Florida. There is limited information on how to grow this crop in Florida. Like hops, hemp is another recently introduced crop in the state, with one of the major yield-limiting factors of premature flowering induced by inadequate day length. This article provides guidelines for hemp growers in Florida on the use of supplemental lighting to control flowering and improve growth of hemp under Florida’s environmental conditions. Written by Johan Desaeger, Jacqueline Coburn, and Shinsuke Agehara, and published by the UF/IFAS Horticultural Sciences Department; 4 pp.
