Estimation of physiological parameters on high density plantations and population arrangements of Musa AAA Simmonds
In Uraba, Antioquia (Colombia), there is a shortage of first-semester fruits and a surplus of second-semester fruits as a result of low or high precipitation, respectively, affecting the value of production.

| description | In Uraba, Antioquia (Colombia), there is a shortage of first-semester fruits and a surplus of second-semester fruits as a result of low or high precipitation, respectively, affecting the value of production. An experiment was established during 2015-2016 in an area representative of the region in order to determine the field distribution and plantation density that maximize the agronomic potential of Musa AAA Simmonds cv. Williams. The population arrangement treatments (rectangle, triangle and double row), planting densities (2,000; 2,500, 3,000 and 3,500 plants/ha) and one control (1,700 plants/ha in a triangle) were evaluated in a complete, random block design with three repetitions. In the phenological phases of floral differentiation, flowering and harvest, the gas exchange was quantified with measurements of the photosynthesis rate, internal CO2 concentration, stomatal conductance, transpiration, vapor pressure deficit, and water use efficiency. The leaf temperature, quantum photosynthesis efficiency and efficient use of radiation were also considered. The yield components and fruit quality were estimated with fruit mass, number of hands, number of fruits, length of the last hand and degree of the second and last hand. The results showed that the density 2,500 plants/ha, distributed in a triangle or double row, promoted the best use of the climate elements associated with photosynthetic activity under the environmental conditions of Uraba, Antioquia. |

En el Urabá antioqueño (Colombia) se presenta una escasez de fruto en el primer semestre y una sobreoferta en el segundo semestre, motivada por la baja o alta precipitación respectivamente, situación que afecta el valor de la producción. Se estableció durante los años 2015-2016 en un lugar representativo de la región, un experimento con el objetivo de determinar la distribución en campo y la densidad de plantación que contribuyan a maximizar el potencial agronómico de Musa AAA Simmonds cv. Williams. Los tratamientos arreglo poblacional (rectángulo, triángulo y doble surco) y las densidades de plantación (2.000, 2.500, 3.000 y 3.500 plantas/ha; y un testigo (1700 plantas/ha en triángulo), se evaluaron en un diseño de bloques completos al azar con tres repeticiones. En las fases fenológicas de diferenciación floral, floración y cosecha, el intercambio de gases se cuantificó con mediciones de tasa de fotosíntesis, concentración interna de CO2 conductancia estomática, transpiración, déficit de presión de vapor y eficiencia en el uso del agua. También se tuvieron en cuenta la temperatura de la hoja, la eficiencia cuántica de fotosíntesis y el uso eficiente de la radiación. Los componentes de rendimiento y la calidad del fruto se estimaron con la masa del fruto, numero de manos, numero de dedos, longitud de la última mano y grado de la segunda y última mano. Los resultados demostraron que la densidad de 2.500 plantas/ha distribuidas en triángulo o doble surco, promovió el mejor uso de los elementos del clima asociados con la fijación de CO2 en las condiciones ambientales de Urabá, Antioquia.
