Publication Conjunto Tecnológico para la Producción de Tomate de Ensalada(2021) Cortés Pérez, Mildred; Fornaris Rullán, Guillermo J.; Martínez, Sonia L.; Rivera, Luis E.; Lugo, María de L.; Cabrera, Irma; Armstrong, Arístides; Rosa, Evelyn; Estévez de Jensen, Consuelo; Vicente, Nydia; Comas, Myrna; Hernández Heredia, Ermita; University of Puerto Rico at Mayaguez; College of Agricultural Sciences; Agricultural Experimental StationEsta publicación presenta información básica sobre el cultivo de tomate de ensalada, así como una serie de prácticas de producción, algunas de las cuales han sido desarrolladas por el programa de investigación de la Estación Experimental Agrícola. Además, se incluyen otras prácticas agrícolas que han sido utilizadas a través de los años por los agricultores en la producción comercial de este cultivo. También incluimos un Presupuesto Modelo, el cual presenta un estimado de los gastos e ingresos por cuerda en una siembra comercial. Este Conjunto Tecnológico es una guía técnica de mucha utilidad para sus usuarios y muy práctica para el agricultor que quiere optimizar su producción. Las prácticas recomendadas promueven la conservación de los recursos naturales con el fin de mantener en armonía el desarrollo agrícola y el medio ambiente.Publication Assessment of Two Sweet Orange Cultivars Grafted on Selected Rootstocks Grown on an Inceptisol in Puerto Rico(Horticulturae, 2020-05-18) Tirado Corbalá, Rebecca; Segarra Carmona, Alejandro E.; Matos Rodríguez, Manuel; Rivera Ocasio, Dania; Estévez de Jensen, Consuelo; Pagán, Jeniffer; University of Puerto Rico at Mayaguez; College of Agricultural Sciences; Department of Crops and Agro-Environmental SciencesSweet oranges in Puerto Rico and other citrus-producing areas in the world have been greatly affected by the Huanglongbing disease (HLB). Historically, most of Puerto Rico’s citrus production has been located from 0–600 m above sea level, where fruit acquire a desirable color and flavor due to climatic conditions. However, higher populations of the disease vector Diaphorina citri Kuwayama have been reported at these elevations in Puerto Rico. Although only 6.4% of the land area is located above 600 m, it is composed mainly of environmentally sensitive or non-arable land where Inceptisols are the dominant soil order. For that reason, ‘Marr’s Early’ and ‘Pera’ sweet orange (Citrus sinensis) scions grafted on ‘Carrizo’, ‘HRS 802’, and ‘HRS 812’ rootstocks were planted in Alonso clay series Inceptisol (Oxic Humudepts) at 649 m in 2010. Tree growth parameters (height, diameter, canopy volume) and yield efficiency were measured. Fruit quality was determined from juice content (%), total soluble solids [°Brix], and pH. Leaf tissue analyses showed an optimum range for Ca, Mg, Na, P, B, Cu, and Zn, an indicator of tree health. A few were high (i.e., N and P) or in excess (i.e., Fe), but no clear connection to specific scions or rootstocks could be established. Tree height, tree diameter, fruit production, and juice content were higher in both sweet oranges grafted on ‘HRS 802’ compared with those on ‘HRS 812’ and ‘Carrizo’. Therefore, ‘HRS 802’ rootstock can be recommended to local farmers growing sweet oranges in Alonso series soil.Publication El Trípido de la Flor del Frijol(Agricultural Experiment Station, 2023-03-14) Cabrera Asencio, Irma; Estévez de Jensen, Consuelo; University of Puerto Rico at Mayaguez; College of Agricultural Sciences; Department of Crops and Agro-Environmental SciencesMegalurothrips usitatus es conocido como el trípido de la flor del frijol o el “asian bean thrips” es una plaga invasiva y fue recientemente reportado en Puerto Rico por la Clínica de Diagnóstico de la Estación Experimental Agrícola de Juana Díaz, UPRM. Esta plaga es muy agresiva que afectas el rendimiento de las Fabáceae.Publication Early Response of ‘Mexican’ Lime, ‘Fina’ Clementine Mandarin, and ‘Campbell’ Valencia Orange on Selected Rootstocks Grown under Fertigation Practices in an Oxisol in Puerto Rico(Horticulturae, 2022-06-11) Tirado Corbalá, Rebecca; Román Paoli, Elvin; Segarra Carmona, Alejandro E.; Estévez de Jensen, Consuelo; Rivera Ocasio, Dania; College of Agricultural Sciences; Department of Crops and Agro-Environmental SciencesIn Puerto Rico, Huanglongbing (HLB), detected in 2009, continues to produce losses in orchards across the island. Efforts to produce clean propagation materials and select different combinations of scions and rootstocks to mitigate the disease have been a priority. In 2016, an experiment was established in Isabela in Coto clay series soils at 120 m to assess ‘Mexican’ lime, ‘Fina’ clementine mandarin, and ‘Campbell’ Valencia orange grafted in ‘Swingle’ citrumelo, ‘HRS 812’, and ‘HRS 897’. Tree growth parameters, tree fruit production, HLB incidences, and tree mortality were evaluated under a fertigation system. Higher fruit production was obtained with ‘Fina’ clementine mandarin and ‘Campbell’ Valencia orange when grafted in ‘HRS 812’ followed by ‘HRS 897’. ‘Mexican’ lime had higher fruit production when grafted in ‘HRS 897’. On the basis of total fruit production and HLB incidence, ‘HRS 812’ was outstanding, yielding fruits with higher values even though they were infected with HLB. Moreover, ‘HRS 897’ rootstock was demonstrated to be a potential rootstock for the Puerto Rico conditions.
