“…Silicon fertilized drought stressed plants of soybean maintained 29.53% higher relative water content than deprived drought stressed seedlings (Shen et al 2010). The enhanced ability of drought stressed silicon treated plants might be related to decrease in transpiration rate because of silicon deposition beneath the cutical (Sacala 2009;Kurdali et al 2013).…”

“…Normally, the deleterious effect of drought is eliminated through silicon nutrition by inducing several physiological changes e.g. osmotic adjustment (Ahmad and Haddad 2011), improved photosynthetic rate (Ahmed et al 2011;Kurdali et al 2013), maintenance of photosynthetic pigments and apparatus (Chutipaijit et al, 2012), increased water status of plants (Ahmed et al 2013), decrease decomposition of chlorophyll (Kurdali et al 2013), lowered transpiration rate (Ahmed et al 2013), improved nutrient use efficiency (Miao et al 2010) and up-regulation of plant defense system (Sacala 2009;Milne et al, 2012) and finally increased yield (Hakim et al 2012) in plants facing water deficit. A significant improvement in shoot length, and leaf area index with silicon fertilization reveals that it was beneficial to enhance the growth of maize hybrids under drought stress (Tables 3 and 4).…”

“…Different mechanisms are reported to induce drought tolerance in plants through silicon treatment including increased water status of plants (Kurdali et al 2013), improved photosynthetic efficiency (Chen et al 2011), osmoregulation or osmotic adjustment (Sacala 2009;Ahmad and Haddad 2011), maintenance of photosynthetic apparatus and pigments (Hamayun et al 2010;Chutipaijit et al 2012), up-regulation of plant defense system (Ahmed et al 2013), and lowered transpiration rate (Kurdali et al 2013).…”

Field crops are subjected to numerous inconsiderate climatic hazards that negatively affect physiological processes, growth and yield. Drought is one of the major abiotic factors that limits the agricultural productivity especially in the arid and semi-arid areas of the globe. Silicon (Si) is a naturally occurring beneficial nutrient which modulates plant growth and development events and has been known to improve the crop tolerance to abiotic stresses. With the objective to investigate the role of silicon nutrition on maize hybrids under limited moisture supply, a two year field study was conducted during 2010-11 at Post Graduate Research Station (PARS), University of Agriculture Faisalabad, Pakistan. We evaluated growth of two maize hybrids P-33H25 and FH-810 under well watered (100% field capacity) and water deficit situation (60% field capacity) as affected by Si application. Silicon was added in soil @ 100 mg/kg using Calcium Silicate as source. Water deficit condition significantly reduced agro-morphological and physiological attributes of maize plants. Silicon application significantly increased the plant height, leaf area index, yield and related attributes along with improvement in photosynthetic rate, leaf water status and osmotic adjustment under limited moisture supply. It was concluded that silicon application to droughtstressed maize enhanced its growth and yield owing to improved photosynthetic rate, higher osmotic adjustment, increased water status and lowered transpiration.

“…However, the role of silicon in crops is not particularly well understood (Casey et al 2003). Silicon plays a very important role in the reduction of the plants vulnerability to biotic and abiotic environmental stress (Fauteux et al 2005, Mitani and Ma 2005, Ma and Yamaji 2006, Liang et al 2006, Gunes et al 2007, Sacała 2009). This component increases the plants' resistance to pathogens and pests (Samuels et al 1993, Fawe et al 1998, Raven 2003, Henriet et al 2006, Cai et al 2009).…”

Sugar beet is one of seven plant species that are classified as silicon bio-accumulators (Guntzer et al 2012).…”

The effect of marine calcite (containing calcium and silicon mainly) foliar fertilization on the sugar beet root yield and technological quality relative to the control (treatment 0) was investigated. Study was conducted in 2011-2012 in the southeastern region of Poland, in Sahryń (50°41'N, 23°46'E). The cultivar of sugar beet was Danuśka KWS. Two treatments of foliar fertilization: (1) treatment (in the stage of 4-6 sugar leaves -262.0 g Ca/ha, 79.9 g Si/ha, and three weeks later -524.0 g Ca/ha, 159.8 g Si/ha); and (2) treatment (in the stage of 4-6 sugar leaves -524.0 g Ca/ha, 159.8 g Si/ha, three weeks later -524.0 g Ca/ha, 159.8 g Si/ha). Calcium and silicon foliar fertilization resulted in increases of: (1) the root yield (average for both treatments about 13.1%; (2) the leaf yield (about 21.0%); (3) the biological sugar yield (about 15.5%), and (4) technological yield of sugar (about 17.7%) compared with the control treatment. At the same time a positive effect on the roots technological quality was found. It was a significant reduction of alpha-amino-nitrogen content and tended to reduce the content of potassium and sodium.

Our current understanding of silicon (Si) availability in agricultural soils is reviewed and knowledge gaps are highlighted. Silicon is a beneficial rather than essential plant nutrient and yield responses to its application have been frequently demonstrated in Si-accumulator crops such as rice and sugarcane. These crops are typically grown on highly weathered (desilicated) soils where soil solution Si concentrations are low. Increased yields are the result of simultaneous increases in plant tolerance to a wide range of biotic (plant pathogens, insect pests) and abiotic (water shortage, excess salts, metal toxicities) stresses. Traditionally, soil solution Si is viewed as being supplied by dissolution of primary and secondary minerals and buffered by adsorption/desorption of silicate onto Al and Fe hydrous oxide surfaces. In recent years it has become recognized that phytogenic cycling of Si [uptake of Si by plants, formation of phytogenic silica (SiO 2 × nH 2 O) mainly in leaves and subsequent return of this silica to soils in plant litter] is the main determinant of soil solution Si concentrations in natural forests and grasslands. Considerable diminution of the phytogenic Si pool in agricultural soils is likely due to regular removal of Si in harvested products. A range of extractants (unbuffered salts, acetate-based solutions, and acids) can provide valuable information on the Si status of soils and the likelihood of a yield response in rice and sugarcane. The most common Si fertilizers used are industrial byproducts (e.g., blast furnace slag, steel slag, ferromanganous slag, Ca slag). Since agriculture promotes soil desilication and Si is presently being promoted as a broad spectrum plant prophylactic, the future use of Si in agriculture is likely to increase. Aspects that require future research include the role of specific adsorption of silicate onto hydrous oxides, the significance of phytogenic Si in agricultural soils, the extent of loss of phytogenic Si due to crop harvest, the role of hydroxyaluminosilicate formation in fertilized soils, and the effect of soil pH on Si availability.
