“…However, many researchers have already shown that silicon could increase the tolerance of plants exposed to stressful environments (Kaya et al, 2006;Liang et al, 2008). Si-induced growth improvement under water-deficit conditions has been observed in different species such as wheat (Gong and Chen, 2012), rice (Chen et al, 2011), and soybean (Shen et al, 2010).…”

The influence of foliar application of silicon (Si) on chlorophyll contents, chlorophyll fluorescence, and growth of four wheat cultivars differing in drought tolerance (Sirvan and Chamran, as relatively drought tolerant, and Shiraz and Marvdasht, as drought sensitive) was examined under water deficit (100% and 40% F.C.) created in a greenhouse. The results showed that water deficit decreased shoot and root lengths, shoot dry weight, root dry weight, water utilization efficiency, chlorophyll a and b, and chlorophyll stability index. In contrast, foliar application of Si improved plant growth parameters and chlorophyll pigment concentration under water deficit; however, it did not significantly affect wheat growth under control conditions. Limited water supply reduced the values of minimal fluorescence from dark-adapted leaf (F 0 ), maximal fluorescence from dark-adapted leaf (F m ), maximum quantum yield of PSII (F v /F m ), effective quantum yield of PSII (ΦPSII), photochemical quenching (q P ), and apparent photosynthetic electron transport rate (ETR). However, under water deficit, foliar application of Si application increased the earlier mentioned parameters. In contrast, nonphotochemical quenching (q N ) and F 0 /F m increased under water deficit, and application of Si further improved these parameters. Chlorophyll fluorescence analysis suggested that Si alleviated water deficit-induced adverse effects by reducing nonphotochemical quenching, while increasing F v /F m and q P , so that it improved the light use efficiency in the four wheat cultivars under stress. Overall, we concluded that drought-sensitive cultivars (Shiraz and Marvdasht) could resemble resistant cultivars upon foliar application of silicon.

“…), did not improve the drought tolerance nor influenced the dry mass production in both species. Although, the addition of fertilizer rich in calcium-magnesium silicates increased drought tolerance, keeping the membrane permeability, in corn seedlings (Kaya et al, 2006), indicating that those plants used the irrigation water efficiently ( Table 1).…”

“…Silica accumulation in the transpiration organs causes the formation of a double layer of cuticular silica, reducing the water loss by transpiration, which increases the water-use efficiency by the plant and enhances the resistance to biotic and abiotic stresses, such as the ones caused by chewing insects (Nwugo & Huerta, 2008). According to Kaya et al (2006), the addiction of silicon increased the tolerance to water stress in corn seedlings, maintaining the membrane permeability.…”

RESUMO Adubação silicatada e lâminas de irrigação na produção do milhoOs silicatos de cálcio e magnésio, quando aplicados aos solos, têm efeito sobre suas propriedades físico-químicas e sobre a nutrição de plantas, uma vez que são fontes de silício, cálcio e magnésio. O objetivo deste trabalho foi avaliar a produção de grãos de milho, irrigado e adubado com silicato de cálcio e magnésio. O experimento foi conduzido em casa de vegetação, no município de Campina Grande-PB, utilizando-se vasos plásticos com 80 kg de solo. Os tratamentos resultaram da combinação de quatro lâminas de irrigação, referentes a reposições de água, correspondentes a 50, 75, 100 e 125% da evapotranspiração da cultura, com níveis de adubação de 0, 82, 164 e 246 g de silicato de cálcio e magnésio, com três repetições. O delineamento experimental foi em blocos ao acaso, sendo as lâminas de água distribuídas em faixas e as doses de silício compondo as subparcelas. A produção do milho foi significativamente influenciada pelas dosagens de silicato de cálcio e magnésio e pelas lâminas de água, obtendo-se a maior produção de grãos com a dosagem de 164 g vaso -1 e maior lâmina de irrigação. A eficiência de uso da água na produção de grãos de milho tendeu a diminuir, sempre que as lâminas de irrigação aumentaram. A melhor eficiência de uso da água ocorreu com a utilização de lâminas entre 87 e 174 mm e da dose de silicato de 164 g vaso -1 .Palavras-chave: silício, milho irrigado, produção de grãos. Silicate fertilizer and irrigation depth in corn production 1 Calcium-magnesium silicates improve the soil physicochemical properties and provide benefits to plant nutrition, since they are sources of silica, calcium and magnesium. The objective of this study was to evaluate the grain yield of irrigated corn fertilized with calcium-magnesium silicate. The experiment was carried out in a greenhouse in Campina Grande -PB, Brazil, using plastic pots containing 80 kg of soil. The treatments consisted of the combination of four irrigation depths, related to water replacement of 50, 75, 100 and 125% of the crop evapotranspiration, with fertilizer levels of 0, 82, 164 and 246 g of calcium-magnesium silicate, with three replications. The experimental design was in randomized blocks, with the irrigation depths distributed in bands while the silicon levels constituted the subplots. Corn yield was influenced by calcium-magnesium silicate and by irrigation depth, obtaining the greatest grain yield with the dose of 164 g pot -1 irrigated at the highest water level. The water-use efficiency of in corn production tended to decrease when the irrigation depth was increased. The best water-use efficiency was observed when the irrigation level was between 87 and 174 mm, and the dose of silicate was 164 g pot -1 .

“…In addition, Natural Minerals Compound treatments increased fruit size which may be attributed to that silicon increase the absorption of potassium which maintains the plant water status. In this respect, Kaya et al (2006) reported that, the presence of silicon may result in better supply of potassium. Also, silicon could earlier the harvest date by increasing fruit TSS/ acid ratio and Vitamin C and to decrease fruit acidity.…”

“…Also, application of (Si) influenced not only silicon nutrition of the citrus trees, but also, optimized other plant micronutrient nutrition aspects, Matichenkov et al (2001). Moreover, addition of (Si) may increase concentration of (Ca) in plant tissues and hence restore membrane integrity in water stressed plants, also, the presence of Si may result in better of supply of (K), Kaya et al (2006). On the other hand, this improvement on leaf mineral contents may be the fact that it induces positive effect on physical condition of the soil, creates favorable conditions for root growth and nutrient absorption it supplies much nutrient and it facilitates the trees of fixed nutrients to be absorb as a result of application of organic and biofertilizers Cook (1982).…”
