“…So, decreases the bypass flow of transpired water that crosses the root cells towards the xylem vessels and provides a barrier to cuticular transpiration (Savvas et al 2009). Such effects of Si increase the relative water content of plant tissues so hold leaves erect and strengthening the stem to prevent lodging that results in improved accommodation of light in plant community thus improving photosynthesis (Abdalla 2009). …”

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.

“…It is chemically composed of Sio 2 (86 to 89%) in a soluble form available to plants and small amount of trace elements. It is considered as a complete, long lasting, recyclable and environmentally friendly soil enhancer by improving the physical structure of soil, aerating the plant ' s root zone, minimizing leaching and runoff thus increasing soil, water retention and reducing watering subsequently, diatomite promotes stronger, healthier, higher-yielding plants that mature quickly and acquire self resistance against abiotic and biotic stresses (Kruger, 2006;Jessen, 2007;Abdalla, 2009 and Abdalla, 2011 a).…”

A pot experiment was carried out during two successive seasons (2014 and 2015) at Salinity and Alkalinity Soil Research Laboratory in Alexandria. The goal of this work was to study the response of rosemary (Rosmarinus officinalis L.) plants irrigated with saline water at 0, 2000 and 4000 ppm NaCl to the application of antistress agents (salicylic acid "SA" at 0 and 0.2 mM and diatomaceous earth "DDM" at 0 and 6 g/10 kg soil). The effect of these antistress agents on the vegetative growth, volatile oil percentage and its chemical composition were recorded. In general results indicated that irrigation with saline water and antistress agents (DDM and SA each of them solely) had a significant effect on vegetative growth expressed as plant height, number of branches/plant, herb fresh and air dry weights and volatile oil percentage as compared to control in most treatments in both cuts of the two seasons. Moreover the plants received diatomaceous earth (DDM) at 6 g/10 kg soil combined with irrigation with non saline water (tap water) recorded the highest values of vegetative growth and volatile oil percentage in both seasons at the two cuts. Also the highest camphor content was achieved with this treatment. Proline content was decreased with increasing the rate of diatomaceous earth followed by salicylic acid, this refers to the response of rosemary plants grown under salt stress to the application of antistress agents (DDM and SA).

“…It also increases the synthesis of RNA and DNA. This situation reduces transpiration and chlorophyll destruction, whereas it increases CO₂ assimilation rates which eventually resulted in an elevated rate of growth and yield (Hanafy et al, 2008;Abdalla, 2009;Ulmer, 2010).…”

Salt toxicity is one of the major problems in modern agriculture. Plants can employ silicon as a protective agent against stresses and the mechanisms of this process remain unknown. Two Egyptian clover (Trifolium alexandrinum) cultivars differing in salinity tolerance were used (Helaly, salt sensitive and Sarw1, salt tolerant). They were grown in pots filled with normal and saline soil (2000 and 3000 ppm) in the absence or presence of diatomites (0, 1.5, 3 and 4.5 g/kg soil). Results indicated that diatomite significantly offset the negative impacts of salinity and increased tolerance of sensitive cultivar of clover (Helaly) to salinity stress. Salinity decreased markedly all measured growth parameters (plant height and fresh and dry weight of fodder/pot), photosynthetic rate , the percentage of relative water content (%RWC), percentage of membrane stability index (%MSI), total photosynthetic pigment, and the contents of each of magnesium (Mg), potassium (K), phosphorus (P), and calcium (C) while it increased the levels of both amino acids, proline and sodium (Na) in both T. alexandrinum cultivars, however the effect was more profound on the sensitive line. Addition of diatomite at an upgraded rates solely or combined with both concentrations of NaCl significantly increased the above measured growth parameters, photosynthesis, %RWC, %MSI, total pigment and the accumulation of each of Mg, K, P and Ca. Moreover, it synergistically increased the content of total amino acids while, on the other hand, reduced the contents of proline and Na. Notably, the impact of diatomite in mitigating the deteriorative effect of salinity was clearly manifested more in sensitive lines of clover than in tolerant ones and under the higher dose of salinity (3000 ppm) as compared to the lower dose (2000 ppm). Moreover, diatomite fertilization either alone or interacting with salinity induced two distinctive protein electrophoratic bands (233 and 25 KD) which were absent in either the control or salinity stressed cultivars. In this respect, diatomite was most effective at 3 g/kg on Helaly and 4.5 g/kg on Sarw1 imposed to the higher dose of salinity (3000 ppm). Diatomite application either alone or combined with salinity induced several distinguished amplified DNA fragments in both clover cultivars using PCR-RAPD analysis , although the number of induced polymorphic DNA fragments were more in Helaly than in Sarw1. These results indicate that diatomite recovered and improved the morphologic, metabolic and biochemical status of both cultivars under salinity stress and especially the sensitive line (Helaly).
