Highlights Passive wick lysimeter performance was tested against soil water balance and simulation models under high perched table conditions. lysimeters overestimated deep drainage as compared to models. Lysimeter data inflated NO3-N leachate estimates, questioning the reliability in similar field The out-row placed recorded higher volumes than in-row placed. Abstract. Understanding nutrient dynamics is pivotal for agricultural environmental research, particularly accurate measurement of...

Organic heirloom tomatoes ( Solanum lycopersicum L.) are difficult to grow in Florida as a result of root-knot nematodes Meloidogyne spp.) (RKN) and hot, humid growing conditions. Although grafting with resistant rootstocks has been shown effective for RKN management tomato production, little research conducted on grafted under In this 2-year study, two susceptible scions, ‘Brandywine’ ‘Flamme’, were onto hybrid rootstocks, i.e., interspecific rootstock ‘Multifort’ S. × habrochaites )...

Grafting has many purposes in vegetable production. It is used for control of soilborne pathogens, season extension protected culture, and improving productivity cucurbitaceous solanaceous crops. Consumers desire heirloom tomatoes ( Solanum lycopersicum ) their perceived excellent flavor. Heirloom are susceptible to diseases may benefit from grafting onto more robust, disease-resistant rootstocks especially under organic In this two-year study, tomato ‘Brandywine’ was grafted hybrid...

The state of Florida ranks third in the United States beer production by volume, yet does not boast a commercially viable barley crop. This presents potential market for Florida-grown barley.

Florida is a major fresh-market cabbage ( Brassica oleracea L. var. capitata ) producing state in the United States. The current production system relies on bare ground and subirrigation that requires large volume of water to irrigate crop. facilitates maximum 48,438 plant/ha, while there potential increase plant population per area using plasticulture drip irrigation. objectives this study were determine optimum arrangement maximizes marketable yield for high system. Cabbage was grown...

Carrot ( Daucus carota ) production has increased in North Florida and South Georgia since 2015. Deep sandy soils, moderate winter climate, availability of irrigation water, proximity to eastern markets are favorable for carrot the region. Nitrogen (N) is required successful production, current recommended N application rate 196 kg·ha −1 . The objective this study was verify soils using industry standard cultivars practices. whole fresh market, Choctaw Maverick, cut-and-peel Triton Uppercut...

A growing number of clinicians have been using laboratory light‐cured resins as a substitute for porcelain veneers. These new systems offer advantages over porcelain. In addition to possessing the ability being repaired or modified directly in oral cavity, they can be used with virtually any alloy. This two‐year study dealt clinical evaluation Dentacolor veneering agent on posterior crowns. Forty restorations were inserted into series patients and evaluated following characteristics: color...

Seepage is characterized as an inefficient irrigation method with regard to water and nutrient use. There a need for economically viable alternative seepage, which increases crop productivity profitability in Florida. The use of plastic mulch drip cabbage ( Brassica oleracea var. capitata ) production plant population per area reduces the requirement. However, plasticulture has high capital investment operating cost. objectives this study were compare traditional seepage bare ground systems...

The cost of seed accounts for nearly 10% the estimated production chipping potato ( Solanum tuberosum ) in Florida. Optimizing piece spacing can reduce costs without affecting yield. This study evaluated effects on yield, quality, and economic revenue north A field experiment was conduct during spring 2013, 2014, 2016 Hastings, FL, with a split-plot randomized complete block design. In-row spacings 10, 15, 20 (industry standard), 25, 30 cm were assigned as main plot S. cultivars (Atlantic,...

In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high tables are one most inefficient methods irrigation, though some management practices can contribute to better soil moisture uniformity. Subsurface drip apply below surface by microirrigation, improving distribution and time required raise table for irrigation.

Weather has a major influence on cabbage ( Brassica oleracea var. capitata L.) production. Variation in yield between years and cropping seasons is common North America. Cabbage Florida historically been cultivated bare ground with seepage irrigation. The objectives of this study were to compare profit production system used an alternative plasticulture system. Data from various trials combined by create regression equations that predicted based air temperature solar radiation significantly...
