During the month of April, Florida rainfall has been scarce. Groves are drying out after some areas enjoyed more rain than normal during the El Niño winter. The dry weather has growers busy running irrigation. Keeping HLB-infected trees well-watered is especially important to reduce plant stress. That was the message Tripti Vashisth, University of Florida Institute of Food and Agricultural …
By Tripti Vashisth and Mary Sutton Prolonged water deficits can negatively impact flowering, fruit growth, crop load and fruit quality. Unfortunately, HLB-affected trees are more susceptible to water deficits than healthy trees due to extensive root loss. Observing HLB-affected trees throughout the dry season showed that severely symptomatic trees consistently had lower leaf water potential than mildly symptomatic trees. This …
By Tripti Vashisth Huanglongbing (HLB) severity is associated with small fruit sizes and lower fruit numbers at harvest. Moreover, small fruit are more likely to drop and drop earlier during preharvest fruit drop. Unfortunately, management practices suggested to increase fruit size or reduce drop have had mixed results. So, before looking for ways to increase fruit size and number, it …
By Sandra M. Guzmán Efficient irrigation management is crucial in optimizing tree growth and promoting sustainable management practices in modern agriculture. This article introduces IrrigMonitor, an Internet of Things data visualization platform developed at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) Smart Irrigation and Hydrology Lab. IrrigMonitor is a …
By Davie Kadyampakeni, Sandra M. Guzmán and Ajia Paolillo Using soil moisture sensors for irrigation scheduling can reduce water stress in citrus trees. Sensors that are easy to calibrate and maintain, specifically designed for managing irrigation and fertigation on Florida’s sandy soils, are the preferred choice. These tools enable growers to use their water resources wisely and efficiently. There are …
By Davie Kadyampakeni Citrus trees require water to be able to carry out the natural processes of growth, making food, and developing fruit and juice. To get the water from the soil, the fibrous roots do the extraneous work of absorbing the water and carrying it via the transpiration stream to the leaves. The water in the soil is made …
In a virtual seminar for growers on July 19, Davie Kadyampakeni reinforced that optimal, balanced nutrition and frequent irrigation can improve HLB-affected citrus trees, yield and fruit. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Citrus Research and Education Center in Lake Alfred. NUTRITION“Citrus fruit yields, juice quality and canopy size …
By Rhuanito S. Ferrarezi and Mark A. Ritenour Citrus under protective screen (CUPS) is a modern production system that excludes the Asian citrus psyllid and, consequently, the devastating disease citrus greening (huanglongbing or HLB) from plants cultivated in screenhouses. A recent study investigated the effect of different irrigation management strategies on fruit yield and quality of grapefruit grown in CUPS. …
By Davie Kadyampakeni, Samuel Kwakye, Hossein Ghoveisi, Lauren Diepenbrock and Jawwad Qureshi Deficit irrigation practices can reduce water and energy costs, thus potentially increasing water-use efficiency and water savings in citrus production. Irrigation management through deficit applications, if timed at periods of reduced water demand, could help trigger increased root water and nutrient uptake while synchronizing citrus flush patterns. These …
By Ajia Paolillo As the season moves from winter to spring, the irrigation requirements of citrus trees change. Typically, February through May is the drier time of year in Florida with low rainfall amounts in most areas. However, during this period, the trees are actively producing leaves and flowers, setting fruit, and pumping resources to the growing fruit during cell …
Use of irrigation for citrus in Brazil’s state of São Paulo has grown by almost 33% in the last six years, according to Citricultor magazine, published by Fundecitrus. The magazine cites irrigation and other improved growing practices as causes for a continuing yield rate acceleration. In 35 years, citrus production per hectare in São Paulo has leaped by about 178%, …
By Fernando Alferez, Daniel Boakye, Susmita Gaire and Tim Gast Growing citrus under protective screen (CUPS) structures for fresh fruit production is effective in controlling HLB disease by completely excluding the Asian citrus psyllid (ACP, Diaphorina citri). After several years of research on CUPS to grow HLB-free trees in Florida, and with commercial growers increasingly adopting this technology, there is …
Citrus growers depend on the latest information about best irrigation and nutrition strategies for growing productive trees. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers will share recent results regarding optimal crop management at a workshop and field visit opportunity on Feb. 8 at the Citrus Research and Education Center (CREC) in Lake Alfred. Davie Kadyampakeni, assistant …
A Citrus Expo presentation about best management practices (BMPs) focused on what growers should be doing now in their irrigation and nutrient management programs. The presentation noted that current BMPs were developed prior to HLB’s discovery in Florida in 2005, and that studies are underway to revise the citrus BMPs for nitrogen and phosphorus. The presentation was created by University …
Scientists in Brazil and Florida found that the direct examination of plant canopy temperature can assist in optimizing citrus irrigation management in greenhouses. The researchers were Gustavo Haddad Souza Vieira with the Federal Institute of Espírito Santo in Brazil and Rhuanito “Johnny” Ferrarezi with the University of Florida Institute of Food and Agricultural Sciences. Their study aimed to develop a …
By Ajia Paolillo Throughout the year, it is a good practice to check your irrigation system for leaks, wear, corrosion and other physical damage that can limit the efficiency of the system. Proper irrigation provides the tree with the water it needs, especially during periods of drought and during the important stages of flowering, fruit set and enlargement, and leaf …
By Davie Kadyampakeni and Sandra Guzmán Young citrus trees require optimal irrigation management for vigorous vegetative growth, leaf flushing and the establishment of a dense canopy. Poor practices such as infrequent irrigation or not using irrigation scheduling tools could be costly. Young tree growth also could be impacted by excessive water and nutrient losses. Crop water stress in young trees …
Proper irrigation and nutrient management are necessary to maximize root density and tree health, especially in trees infected with HLB. Davie Kadyampakeni, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, shared a few irrigation and nutrient research updates during the March episode of the All In For Citrus podcast. IRRIGATION RECOMMENDATIONS Young citrus trees require optimal …
A solid nutrition and irrigation program can enhance the productivity of HLB-affected trees and improve citrus tree health, potentially making production profitable even under HLB conditions. This was the subject of Davie Kadyampakeni’s talk during a March 9 OJ Break virtual meeting held for citrus growers. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant …
Artificial intelligence (AI) can be an overwhelming topic, but Sandra Guzmán says it is easier to swallow when it helps growers. Guzmán, an agricultural engineering assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center, has been working directly with growers to integrate the benefits of in-field technology. The influx …
