“…The grain yield responded in a quadratic manner to the silicon doses via seed coating (Figure 2E), obtaining a maximum point at 17.53 g kg -1 of seeds. Dantas Júnior et al (2013), also studying doses of calcium and magnesium silicate, obtained quadratic responses from the stem and leaf dry matter, with a maximum dose of 164 g per pot of 80 kg of soil.…”

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.

Natural Zeolite for The Purification of Saline Groundwater and Irrigation Potential Analysis

et al. 2022

Groundwater is one of the main sources of water for irrigation used worldwide. However, the application of the resource is threatened by the possibility of high saline levels, especially in low-lying coastal regions. Furthermore, the lack of readily accessible materials for successful treatment procedures makes the purification of such water a constant challenge. Based on the fact that natural zeolite is one of the easily accessible and relatively cheap filter materials, this study examined the potential use of high-salinity groundwater filtered by natural zeolite for irrigation. Zeolite-filled filters at two different depths (0.5 m and 1 m) were studied. The samples were collected from the low-lying areas of Dar es Salaam City, Tanzania. The study observed that when the raw groundwater samples were exposed to the 0.5 m column depth, sodium (Na+) had the lowest removal efficiency at 40.2% and calcium (Ca2+) had the highest removal efficiency at 98.9%. On the other hand, magnesium (Mg2+) had the lowest removal efficiency, at about 61.2%, whereas potassium (K+) had up to about 99.7% removal efficiency from the 1 m column depth treatment system. Additionally, from the salinity hazard potential analysis, most of the samples fell within C4 (based on the electrical conductivity), which is a “very high salinity” class, and based on the quality it means the water cannot be directly applied for irrigation purposes. From the 0.5 m column depth, most of the samples fell within C3 (the “high salinity” class), and from the 1 m column depth most of the samples fell within C1 (“low salinity” class). The findings of this study offer some valuable insight into the prospective use of natural zeolite for the filtration of saline groundwater before its application for irrigation.

Objetivou-se com esse trabalho verificar a capacidade de hortaliças não convencionais em acumular silício, bem como a resposta destas à adubação silicatada. O experimento foi conduzido em casa de vegetação em 2016. Foram avaliados duas doses de adubação silicatada (0 e 50 mg dm-3 de Si), e nove espécies de hortaliças não convencionais (Maranta arundinacea L., Rumex acetosa L., Amaranthus spinosus L., Amaranthus viridis L., Amaranthus retroflexus L., Amaranthus deflexus L., Amaranthus hybridus L., Stachys byzantina K. Koch e Sonchus oleraceus L.), dispostos em delineamento inteiramente casualizado em esquema fatorial 2 x 9, com quatro repetições. Foram determinadas a massas fresca e seca, assim como o teor de Si em todas as plantas. As espécies avaliadas possuem potencial para acumular silício mediante adubação com o elemento. A aplicação de 50 mg dm-3 de Si proporcionou maior teor de Si nas espécies estudadas. A adubação com Si, de modo geral, não influencia na biomassa dessas plantas.
