Effect of the supplementary foliar application of calcium on melon (Cucumis melo L.) production

The effect of supplementary foliar application of calcium on production of Amarillo type melon cv. Natal F-1, was evaluated in Lepanto, Puntarenas.  Evaluated treatments were:  JMX-Ca (4,22 kg CaO/ha), JMX-Ca (2,41 kg CaO/ha), Manvert-Ca (4,22 kg CaO/ha), and control (water).&n...

Monge-Pérez, José Eladio Loría-Coto, Michelle Cucumis melo melon fruit weight °Brix fruit flesh firmness yield quality Pseudoperonospora cubensis Cucumis melo melón peso del fruto °Brix firmeza de la pulpa del fruto rendimiento calidad Pseudoperonospora cubensis The effect of supplementary foliar application of calcium on production of Amarillo type melon cv. Natal F-1, was evaluated in Lepanto, Puntarenas.  Evaluated treatments were:  JMX-Ca (4,22 kg CaO/ha), JMX-Ca (2,41 kg CaO/ha), Manvert-Ca (4,22 kg CaO/ha), and control (water).  The harvest started 58 days after transplant (dat) for all treatments.  Data show an important variability among treatments with respect to number of exportable fruits per linear meter (1,79 – 2,06), exportable yield (13638 – 16126 kg/ha), exportable production (1318 – 1556 boxes/ha), mean fruit weight (1364,3 – 1433,0 g), percentage of total soluble solids (10,90 – 11,88 °Brix), fruit flesh firmness (26,94 – 28,38 N), maximum downy mildew (Pseudoperonospora cubensis) severity at 50 dat (3,83 – 4,17; 1-5 scale), and plant collapse incidence at 58 dat (0 – 1,85 %).  Differences between treatments were significant only for the percentage of total soluble solids; JMX-Ca at 4,22 kg CaO/ha rendered the highest value for this characteristic (11,88 °Brix) compared to JMX-Ca at 2,41 kg CaO/ha and Manvert-Ca at 4,22 kg CaO/ha (10,90 and 11,15 °Brix). But the difference was not significant compared to the control treatment (11,45 °Brix).  In conclusion, there is no economical justification for the supplementary foliar application of calcium under the growing conditions of the trial. Se evaluó el efecto de la aplicación foliar suplementaria de calcio, sobre la producción de melón Amarillo cv. Natal F-1, en Lepanto, Puntarenas.  Los tratamientos evaluados fueron:  JMX-Ca (4,22 kg CaO/ha), JMX-Ca (2,41 kg CaO/ha), Manvert-Ca (4,22 kg CaO/ha), y un testigo (agua).  La cosecha inició a los 58 días después del trasplante (ddt) para todos los tratamientos.  Los datos muestran una importante variabilidad entre los tratamientos en cuanto al número de frutos exportables por metro lineal (1,79 – 2,06), rendimiento exportable (13638 – 16126 kg/ha), producción exportable (1318 – 1556 cajas/ha), peso promedio del fruto (1364,3 – 1433,0 g), porcentaje de sólidos solubles totales (10,90 – 11,88 °Brix), firmeza de la pulpa del fruto (26,94 – 28,38 N), severidad máxima de mildiú velloso (Pseudoperonospora cubensis) a los 50 ddt (3,83 – 4,17; escala 1-5), e incidencia de colapso de la planta a los 58 ddt (0 – 1,85 %).  Solamente se presentaron diferencias significativas entre tratamientos para el porcentaje de sólidos solubles totales; el tratamiento de JMX-Ca a 4,22 kg CaO/ha obtuvo un mayor valor para esta característica (11,88 °Brix) en comparación a JMX-Ca a 2,41 kg CaO/ha y a Manvert-Ca a 4,22 kg CaO/ha (entre 10,90 y 11,15 °Brix), pero no fue diferente del testigo (11,45 °Brix).  Se concluye que, bajo las condiciones en que se desarrolló el ensayo, no se justifica económicamente la aplicación foliar suplementaria de calcio. 2020-10-02 2020-10-05T22:25:11Z 2020-10-05T22:25:11Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/4556 10.18845/tm.v33i4.4556 https://hdl.handle.net/2238/12177 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/4556/5145 Derechos de autor 2020 Revista Tecnología en Marcha https://creativecommons.org/licenses/by-nc-nd/4.0 application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; 2020: Vol. 33 Núm. 4: Octubre-Noviembre 2020; Pág. 89-102 Revista Tecnología en Marcha; 2020: Vol. 33 Núm. 4: Octubre-Noviembre 2020; Pág. 89-102 2215-3241 0379-3982
