Coating Seeds With Silicon Enhances the Corn Yield of the Second Crop

Abstract

The application of silicon is becoming popular in agriculture as an alternative for integrated crop management, owing to the diverse benefits resulting from the accumulation of silicon in grasses and the resultant resistance conferred in plants against biotic and abiotic stresses. The objective of this study was to evaluate whether the application of silicon, via seed coating and leaf application, influences the production and yield components of maize in the second crop. The experimental design was divided into split plots, in which the plots were composed of phyllosilicate doses (0, 5, 10, 15, and 20 g kg-1 of seeds) in the seed coatings and the subplots were composed of foliar applications of potassium silicate (1.0 L ha-1 in pre-dip and 15 days after). We evaluated the plant height, spike insertion height, spike and corncob diameter, number of rows per spike, number of grains per row, the mass of 100 grains, and productivity. The foliar application of potassium silicate had no effect on the yield and yield components of the corn crop. The use of phyllosilicate via seed coating increased the production components and yield of the second corn crop.

Effects of Potassium Silicate Fertilizer on Photosynthetic Characteristics and Yield in Winter Wheat (Triticum Aestivum L.)

“…The practical application of Si-rich products provides for an increase in plant productivity and the reduction of nutrient leaching (Matichenkov et al 2020). Use of phyllosilicate via seed coating increased the production components and yield of the second corn crop (Rodrigues et al 2019). The selected plant growth, yield and biochemical parameters of P. vulgaris were efficiently increased by combined PGPR and silicon fertilization under saline stress in which the marketable value of the crop can be improved (Kumar et al 2020).…”

Potassium silicate as an inducer of abiotic stress resistance in grain sorghum seeds

“…One alternative for lessening the damage caused by water and salt stress is the use of attenuators such as silicon, since this element has several effects on plants, among them resistance to abiotic stresses (ROMA-ALMEIDA et al, 2016). Most of the benefi ts of silicon are due to its being deposited on the cell wall beneath the leaf cuticle, in the form of amorphous silica (SiO 2 .nH 2 O) (FREITAS et al, 2011), forming a cuticle-silica double layer that acts as a protective barrier, reducing water loss in the plant by evapotranspiration (RODRIGUES et al, 2019). In their studies with Si nanoparticles as seed priming, Hussain et al (2019) observed that Si stimulated the activity of antioxidant enzymes and reduced the concentration of ROS (reactive oxygen species), which positively impacted the growth of wheat plants.…”

Análise da aplicação experimental de silício em plantas de milho visando a resistência ao enfezamento vermelho causado por fitoplasma

“…Número de fileiras de grãos por espigas produzidas por plantas de milho tratadas e não tratadas com silício crescidas na ausência de insetos, e de plantas submetidas à alimentação de insetos infectantes e sadios Médias seguidas da mesma letra não diferem entre si, pelo teste de Tukey a 5% de significância Tabela 13. Peso total de grãos (g) produzidos por plantas de milho tratadas e não tratadas com silício crescidas na ausência de insetos, e de plantas submetidas à alimentação de insetos infectantes e sadios Médias seguidas da mesma letra não diferem entre si, pelo teste de Tukey a 5% de significância Em ensaios semelhantes àqueles aqui realizados,Rodrigues et al (2019) relataram que a aplicação de silício em plantas de milho promoveu aumento no número de fileiras, o que gerou maior produtividade. Entretanto, experimentos conduzidos por Martins (2021) revelaram resultados concordantes com aqueles obtidos no presente trabalho, os quais mostraram ausência de diferença significativa entre o número de fileiras de grãos produzidas por plantas tratadas e não tratadas com silício.…”
