Potassium silicate as a resistance elicitor in sweet corn yield traits under water stress
Plant water stress is a major problem in the Cerrado biome of Brazil. Dry periods and random climatic events cause quality and yield losses in sweet corn plants. Compounds, such as silicon (Si), are being studied to reduce the negative impacts of water stress on agricultural crops. Further tests may...

| description | Plant water stress is a major problem in the Cerrado biome of Brazil. Dry periods and random climatic events cause quality and yield losses in sweet corn plants. Compounds, such as silicon (Si), are being studied to reduce the negative impacts of water stress on agricultural crops. Further tests may allow farmers to increase the use of silicon-based compounds. The objective of this study was to evaluate the production parameters of the sweet corn (Zea mays var. saccharata) (Poaceae) Tropical Plus® hybrid with water stress and potassium silicate doses applied with foliar spraying. A randomized block design with four soil water tensions (15, 30, 45 and 60 kPa) and four potassium silicate doses (0, 6, 12 and 24 L ha-1) was used in a greenhouse. The studied factors, alone or in interaction with each other, did not affect most of the sweet corn yield parameters. The hypothesis that these results may have been partially affected by the presence of silicon are discussed. The sweet corn plant yield was affected mainly by the soil water tension of 60 kPa. |

El estrés hídrico en la planta es un problema importante en el bioma Cerrado de Brasil. Los períodos secos y los eventos climáticos aleatorios causan pérdidas de calidad y productividad en las plantas de maíz dulce. Compuestos como el silicio (Si), pueden ser estudiados para reducir los impactos negativos del estrés hídrico en los cultivos agrícolas. Pruebas adicionales pueden permitir a los agricultores aumentar el uso de compuestos a base de silicio. El objetivo de este trabajo fue evaluar los parámetros de producción de maíz dulce (Zea mays var. Saccharata, híbrido Tropical Plus®) con niveles de estrés hídrico y dosis de silicato de potasio aplicadas por pulverización foliar. El diseño experimental fue un diseño de bloques al azar con cuatro tensiones hídricas en el suelo (15, 30, 45 y 60 kPa) y cuatro dosis de silicato de potasio (0, 6, 12 y 24 L ha-1) en invernadero. Los factores estudiados solos o en interacción no afectaron la mayoría de los parámetros de producción de maíz dulce. Se discute la hipótesis de que estos resultados pueden haber sido parcialmente afectados por la presencia de silicio. El rendimiento de la planta de maíz dulce se vio afectado principalmente por el estrés hídrico del suelo a 60 kPa.
