“…The increased tiller number due to calcium silicate application advantageously reflected in increased straw yield it was also reported by Vasanthi et al, 2014. The effect of application of MgSO 4 was conspicuous compared to control but not to the extent of application of silica and borax.…”

The Kole lands a unique wetland ecosystem of Kerala, is located 0.5-1.0m below mean sea level. An experiment was conducted in College of Horticulture, Vellanikkara, Kerala to study the influence of secondary and micronutrients viz. calcium, magnesium and boron on nutrient uptake and yield of rice in Kole lands. Six treatments including the soil test based nutrient application, package of practices recommendation (POPR) of Kerala Agricultural University for rice, combinations of the POPR with magnesium, calcium silicate, boron and absolute control were applied in the crop in a randomized block design with three replications. Higher uptake of nutrients especially primary and micronutrients were noticed by boron and calcium silicate application and lower uptake of Fe and Mn, thereby resulted in higher grain yields of 7.67 t/ha and 7.18 t/ha respectively and straw yield was higher by application of magnesium. Correlation analysis revealed that total uptake of boron, calcium and magnesium had positive and significant correlation with yield whereas negative correlation existed between Fe uptake and yield.

“…Silicon (Si) is one of the elements considered beneficial to plants as its presence can improve some features, while its absence does not significantly affect the life cycle of most plants (Vasanthi et al, 2014). In addition to encouraging and promoting plant growth, Si also alleviates many abiotic stresses including salt stress (Shakoor, 2014).…”

Cape gooseberry (Physalis peruviana L.) cannot tolerate high levels of salinity. Salt stress is one of the most damaging abiotic stresses that affects plant development. However, there are some evidences that silicon (Si) can act as a mitigating agent of environmental stresses. Towards understanding the stress using tissue culture, we investigated the effect of in vitro NaCl-induced salt stress in cape gooseberry and the potential mitigating effect provided by Si. Nodal segments were inoculated in MS medium with different combinations of NaCl concentrations (0.5 and 1.0% NaCl) and silicic acid (0.0, 0.5, and 1.0 g L -1 ). The experimental design was completely randomized, in a factorial design with a control treatment [(2x3) + 1], totalizing 7 treatments. The control treatment consisted of an additional treatment without the addition of any of the factors. Isoenzyme activity, proline content, CO 2 level and biological activity were assessed after 30 d. We found an increase in all antioxidant enzymes (SOD, CAT and POD) activities when salt stress was imposed, indicating that the plant has an efficient system to protect itself against stress. Among these enzymes, Si played a mitigating role only in POD activity. In relation to other evaluated enzymes, NaCl enhanced the EST and MDH activities, followed by a subsequent decrease in MDH. Si showed different performances according to the concentration of NaCl. Electrophoretic analysis represented by bands illustrated these behaviors. Proline content increased as salinity increased, and Si effect was observed by increasing the levels of this amino acid. High CO 2 level was found at the concentration of 1.0% NaCl, and Si contributed to decrease this variable to normal levels. The reduction in the respiratory rates may contribute to the allocation of carbon to other chemical reactions such as the synthesis of new tissues. Salt stress also increased the biological activity of leaves and there was no effect of Si for this variable. We conclude that salt stress causes a great damage to in vitro-grown cape gooseberry plants and the addition of 1.0 g L -1 Si can ameliorate that damage for some characteristics. However, more studies are necessary since the physiological changes played by Si have been poorly understood for dicots.

“…Nano-SiO 2 particles are one of NPs take a great concern by researchers in agricultural practices during the last few years. Silicon is a beneficial element plays vital role for rigidity, mechanical strength, plant growth and development and induced plant's resistance against many abiotic stresses such as salinity, drought, heavy metal toxicities, high temperature and cold stress as well as enhanced the resistance against pests and diseases caused by both fungi and bacteria in different plant species (Ma, 2004;Liang et al, 2007 andVasanthi et al, 2014). Nano-SiO 2 particles have greater spread in wide area, one gram of such particles exhibit wide absorption surface equal to 400 m 2 , so they absorbed better and faster than Si in bulk materials which leads to immediately utilized by plants to achieve their growth and development.…”

An open field experiment was carried out during 2015 and 2016 seasons at the experimental nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Egypt. The purpose of present research was to investigate the effect of foliar application of nano silicon with different concentrations and gypsum soil application on growth, flowering and chemical constituents of Jatropha integerrima plants irrigated with different levels of saline water. The concentrations of saline water were (1000, 2000 and 4000 ppm), in addition to tap water (270 ppm) as a control, simultaneously plants were received monthly foliar application of nano silicon 1 and 2 mM or soil application of gypsum at 20 g/plant, either applied individually or in combination.The results showed that, elevating salt concentration in irrigation water decreased vegetative growth characteristics, flowering traits, leaves anatomy and chemical constituents. In contrast, increasing salinity of irrigation water boosted contents of proline, Ca%, Na%, Cl%, total phenolic and flavonoids. On the other hand, foliar application of nano silicon and soil addition of gypsum treatments either individually or in combination had favorable effects on enhancing vegetative parameters and chemical constitutes, meanwhile decreasing accumulation of Na%, ISSN 2166-0379 2017 http://jas.macrothink.org 137 Cl%, total phenolic and flavonoids in leaves. It can be concluded that, foliar spray of nano silicon combined with soil addition of gypsum was the best effective and economic treatment recommended for mitigating the harmful effect of salinity stress on Jatropha plants irrigated with saline water at concentration up to 4000 ppm.
