Adding silicon to nutrient solution is worth considering
Abstract
Silicon is a mysterious element. It’s not essential for plant growth but sometimes plants absorb more of this than other elements. Slowly we are gaining more knowledge about its positive effects: Increased resistance to diseases and higher production. But much is still unknown.
I. Resumen
El objetivo de esta investigación fue evaluar el efecto del ácido acetilsalicílico y silicio en la nutrición y sanidad
del cultivo de haba (Vicia faba) para integrarlos a un manejo agronómico ante condiciones abióticas y bióticas
adversas como elevadas precipitaciones y humedad relativa para Botrytis fabae. Se estableció un diseño de bloques
completos al azar con siete tratamientos más un testigo y tres repeticiones. Se aplicaron dosis de silicato de calcio
(5 y 15 kg ha-1), ácido acetilsalicílico (1 y 1.5 l ha-1) y su combinación con fertilizantes a los 30 y 50 días. Se evaluaron
parámetros de crecimiento como altura, número de macollos, número de vainas y peso seco. Adicionalmente
se realizó un monitoreo a los 70 y 100 días para determinar el porcentaje de incidencia y severidad de “mancha
chocolate” (Botrytis fabae) cada semana. Los datos fueron analizados estadísticamente mediante un modelo mixto,
DGC (α=0.05). Los resultados indicaron que el silicio y ácido acetilsalicílico contribuyeron positivamente en la
fisiología y producción vegetal, siendo éstos elicitores más eficientes con un sistema de fertilización. Adicionalmente
el silicio a partir de la fuente de silicato de calcio contribuyó a que la enfermedad de “mancha chocolate” tenga los
menores porcentajes de incidencia y severidad.
Palabras clave: haba, Botrytis fabae, silicio, ácido acetilsalicílico, fertilización, elicitores.
II. Abstract
The aim of this study was to evaluate the effect of acetylsalicylic acid and silicon on nutrition and health of faba
bean (Vicia faba) crop to integrate them into an agronomic management under abiotic and biotic conditions such
as high rainfall and relative humidity for Botrytis fabae. A random complete block design was established with
seven treatments plus one witness and three repetitions. Doses of calcium silicate (5 and 15 kg ha-1), acetylsalicylic
acid (1 and 1.5 l ha-1) and its combination with fertilizers were applied at 30 and 50 days. Growth parameters like
height, number of pods, number of branches plant-1 and dry weight were determined. In addition a monitoring was
done at 70 and 100 days. Percentages of incidence and severity of chocolate spot (Botrytis fabae) were determined
weekly. The data were statistically analyzed using a mixed model, DGC (0.05). The results indicated that silicon and
acetylsalicylic acid contributed positively to plant physiology and production, these being more efficient elicitors
with a fertilization system. In addition, silicon from the source of calcium silicate contributed to chocolate spot
disease having the lowest percentages of incidence and severity.
