Florida's K–12 schools provide a potential opportunity to increase market channel options for small- and mid-sized diversified farms, but processing, storage, and distribution resources are extremely limited for smaller producers. This 9-page document serves as a model and case study with steps for producers and other stakeholders to conduct a feasibility study before forming a cooperative to sell local fruits and vegetables to schools and other institutional food-service outlets.

Terminating Cover Crops Effectively for Weed Suppression

Organic corn planted in a cover crop of roller-crimped rye and hairy vetch.

When utilizing cover crops for weed suppression, one important consideration is effective termination before planting the main crop. A major issue with improper termination is that the cover crop can become problematic and compete with the main crop, like other weeds. However, proper planning of the termination timing and method can minimize these issues and maximize the benefits of cover crop use. This 5-page publication discusses herbicide application, roller-crimper termination, tillage, and appropriate growth stages for termination. Written by Pratap Devkota, Michael J. Mulvaney, and David Wright, and published by the UF/IFAS Agronomy Department, February 2021.

Jim Marois, left, and David Wright, professors at the University of Florida’s North Florida Research and Education Center in Quincy, check soybean plants for Asian soybean rust - Friday, July 1, 2005. First discovered in the United States in fall 2004, the crop-killing disease was found growing on cultivated soybeans for the first time this week, at early-planted "sentinel plots" in Florida and Alabama. To help protect the nation’s $16 billion soybean crop, UF researchers are monitoring plants around the state for signs of the disease.

Successful weed control is one of the most important practices for economical soybean production in Florida. This 10-page publication discusses weed control methods for soybean growers. Written by J.

Vegetable amaranth is a beautiful and nutritious vegetable in the family Amaranthaceae. This vegetable has been cultivated in China for more than 400 years and has been introduced to several US states, such as Mississippi and Missouri. Florida’s mild climate combined with amaranth’s exceptional taste, nutrients, and colorful foliage suggest amaranth is a potential crop for commercial production for Florida. This new 7-page publication of the UF/IFAS Horticultural Sciences Department is intended to provide Florida growers with a production guide for vegetable amaranth to enhance its competitiveness and boost the economy by introducing this potential cash crop to growers.

Lettuce Downy Mildew (LDM), caused by the oomycete Bremia lactucae, is the most important disease of lettuce worldwide. LDM has a direct effect on both yield quantity and quality because it may infect lettuce at any growth stage, affecting the marketable portion of the crop. This new 6-page publication of the UF/IFAS Horticultural Sciences Department introduces the LDM disease in Florida lettuce and available control methods and strategies. This publication also introduces the work on LDM in the UF/IFAS Lettuce Breeding Program, which was created to release cultivars adapted to Florida conditions.

Use of Recycled Potting Medium for Containerized Production of Squash

Vegetable growers are keen on cost-cutting measures to increase profitability. Containerized vegetable production can be done in a shade-house or garden, and it often requires commercial potting media. Although expensive, potting media are lightweight and provide high water- and nutrient-holding capacities, and thus they are widely used by growers. Growers often discard or compost the potting media after a single season due to issues such as diseases, pests, and weeds. However, old potting media could be reused for containerized production if appropriately sterilized and amended with fertilizer salts. The current study was conducted to determine the feasibility of using sterilized recycled potting medium amended with fertilizer salts for containerized production of squash. This new 4-page publication of the UF/IFAS Horticultural Sciences Department was written by Marie Dorval, Riphine Mainviel, Vincent Michael, Yuqing Fu, Bala Rathinasabapathi, and Geoffrey Meru.

There is a growing market in the United States and globally for fresh fruits and vegetables with reported health-enhancing properties. This includes blueberries, which are high in antioxidants and have been reported to improve heart health and contain anticancer properties. Fresh-market blueberry sales (conventional and organic) increased by 27% between 2013 and 2017, and that trend is expected to continue. In addition, there is an increasing level of consumer interest in organically grown produce (for environmental conservation, taste, and other perceived benefits), for which some consumers are willing to pay a premium over the price for a conventionally produced crop. This new 8-page publication of the UF/IFAS Horticultural Sciences Department discusses various aspects of organic blueberry production in Florida and is intended for use by those currently using or interested in pursuing organic production.
