Desarrollo productivo de dos variedades locales de maíz (Zea mays L.) con la aplicación de fertilizante mineral y orgánico en la Amazonía Ecuatoriana

Abstract: El maíz es uno de los principales granos en el Ecuador, degran importancia para los pueblos indígenas, quienes loconsideran un generador de vida. En la región Amazónica seviene cultivando desde hace muchos años las variedades Tusillay Zhubay, sin embargo, no existen estudios agronómicos quepermitan determinar un modelo de producción para la región.En base a ello, el objetivo de este trabajo consistió en evaluarel desarrollo productivo de dos variedades de maíz (Zea maysL.) con fertilización mineral y orgánica … Show more

“…On the other hand, a lower plant density may provide each individual plant with better access to resources, which could result in higher dry matter production per plant. However, it is important to consider that a very low density can result in suboptimal use of available space and reduced sunlight utilization, which can negatively affect overall crop yield (Alemán-Pérez et al, 2020). The number of grains per row (Figure 4A) is higher in treatment 1 (31 250 plants ha -1 ), with a statistical difference from treatment number 3 (62 500 plants ha -1 ).…”

“…It is grown on the coast, in the highlands, and in the Amazon under different environmental conditions of temperature, humidity, rainfall, and luminosity. In the Ecuadorian Amazon, two main varieties of corn are grown: Tusilla and Zhubay (Alemán-Pérez et al, 2020). According to Saavedra and Gaibor (2018), corn is the most common annual crop in the Amazon region, with a cumulative frequency of 72.5 %, demonstrating the tradition and importance of the crop in Amazonian production systems.…”

“…Se determinaron los indicadores: número de mazorcas por planta (conteo directo en el campo), número de granos por hilera en la mazorca (conteo visual), longitud de la mazorca (regla graduada), diámetro de la mazorca con y sin granos (pie de rey), número de hileras por mazorca (conteo visual), masa de 100 granos (balanza técnica, Modelo BPE-500 ± 0,001 g), masa de la producción total de cada tratamiento con y sin paja (balanza técnica, Modelo BPE-500 ± 0,001 g) y rendimiento en función de la masa de la tusa (por pesada de la producción total de cada unidad experimental, extrapolada a una hectárea). Estos parámetros coinciden con la metodología planteada por Alemán et al (2020).…”
