| dc.description | This collection of information refers to the effect of planting densities in the pearl onion (Allium cepa L.) crop in Ecuador. Within the agronomic management of the pearl onion crop, many factors that influence the yield stand out and that begin from the preparation of the seedbed to the harvest, within which there are sowing densities, attack by pests and diseases, nutritional deficiencies, irrigation and weed control. Among the conclusions, it is detailed that the area with the highest pearl onion production in Ecuador corresponds to the province of Chimborazo, with approx. 45000 tons per year; the increase in plant density advances the maturity date, increases the percentage of intercepted radiation and the total yield of bulbs and reduces the number of green leaves, number of rings and size of the bulbs; The response to the sowing distance depends mainly on the following factors: type of crop, characteristics of the genotype, sowing method, environmental conditions of the region (climate and soil), purpose of the crop, economic efficiency and the irrigation system and use a planting density of 44 plants / m2 because with this density the best yields and the highest benefit / cost ratio are obtained. | es_ES |

| dc.description.abstract | La presente recolección de información refiere al efecto de densidades de siembra en el cultivo de cebolla perla (Allium cepa L.) en Ecuador. Dentro del manejo agronómico del cultivo de cebolla perla se destacan muchos factores que influyen en el rendimiento y que inician desde la preparación del semillero hasta la cosecha, dentro del cual se presentan densidades de siembra, ataque de plagas y enfermedades, deficiencia nutricional, riego y control de malezas. Entre las conclusiones se detallan que la zona de mayor producción de cebolla perla en Ecuador corresponde a la provincia de Chimborazo, con aprox. 45000 Tn anuales; el incremento de la densidad de plantas adelanta la fecha de madurez, incrementa el porcentaje de radiación interceptada y el rendimiento total de bulbos y reduce el número de hojas verdes, número de anillos y tamaño de los bulbos; la respuesta a la distancia de siembra depende, principalmente de los siguientes factores: tipo de cultivo, características del genotipo, método de siembra, condiciones ambientales de la región (clima y suelo), propósito del cultivo, eficiencia económica y del sistema de riego y utilizar una densidad de siembra de 44 plantas/m2 porque con esta densidad se obtienen los mejores rendimientos y la mayor relación beneficio/costo. | es_ES |
