Florida had the largest fresh-market tomato (Solanum lycopersicum L.) production in the United States, with a value of $437 million and 13,355 ha harvested in 2014. Despite the development of Best Management Practices (BMPs) and University of Florida/Institute of Food andAgricultural Sciences (UF/IFAS) fertilizer recommendations, tomato growers oft...
Article
Florida best management practices include the use of controlled-release fertilizers (CRFs), which are soluble nutrients coated with a resin, polymer, sulfur, or a polymer covering a sulfur-coated urea. The purpose of this study was to compare the effects of three CRFs (coated, homogenized NH4NO3 and urea, and coated KNO3) rates in a hybrid CRF/solu...
Article
Controlled-release fertilizer (CRF) use is a best management practice that may reduce nitrogen (N) loss to the environment. Several factors affect CRF nutrient release; therefore, including CRF in a fertilization program may have challenges. Thus, the study objective was to evaluate the effects ofCRFN rate, source, release duration, and placement o...

Compact growth habit (CGH) tomatoes (Solanum lycopersicum) are determinate plants with shortened internodes and strong side branching due to the brachytic gene (br) that grow either prostrate or upright as a result of unidentified gene(s). Compact growth habit tomatoes do not require staking, tying, or pruning and can potentially be mechanically ha...

Full-text available
Determination of nutrient release duration from controlled-release fertilizers (CRFs) or soluble fertilizers encapsulated in polymer, resin, or sulfur covered fertilizer coated with a polymer differs among manufacturers, but may be determined as 75% to 80% nitrogen (N) release at a constant temperature (e.g., 20 to 25 8C). Increases or decreases in...

Understanding P accumulation and partitioning is essential for improving phosphorus use efficiency (PUE) and minimizing environmental impact. A 2-yr study was conducted to determine P distribution and PUE in tomato (Solanum lycopersicum L.) production as influenced by P application rates in a calcareous soil. Phosphorus was applied at 0, 29, 49, 78...
Article
Florida is the largest fresh-market tomato ( Solanum lycopersicum L.)–producing state in the United States. Although vegetable production requires frequent water supply throughout the crop production cycle to produce maximum yield and ensure high-quality produce, overirrigation can reduce crop yield and increase negative environmental consequences....

Plant-parasitic nematodes pose a problem in agricultural systems by feeding on crops, therefore affecting their yield. Fluensulfone is a chemical that can be applied using various methods to manage the impact of plant-parasitic nematodes on crop production. This 6-page document discusses the characteristics and use of fluensulfone as a tool for nem...
Article
Potassium application rates based on a reliable soil testing method are critical for maximizing crop yields and minimizing fertilizer costs.
