  author={Mukhtar Ahmed and Fayyaz-ul Hassen and Ummara Qadeer and Muhammad Aqeel Aslam},
Pot experiments were conducted at the PMAS, Arid Agriculture University, Rawalpindi, Pakistan during 2007 repeated during 2008 to study the effect of silicon and nanoirrigation (W40) on drought tolerance mechanism of sorghum. According to experimental design, the silicon fertilization was divided into two levels: control (no application of potassium silicate) Si0 and application of silicon Si200 (200 mlL-1 of potassium silicate per kg of soil). Irrigation was divided into two levels: crop…

Amelioration of Drought in Sorghum (Sorghum bicolor L.) by Silicon
The results showed that drought-tolerant cultivars accumulated maximum Si under Si treatment versus Si absence, which resulted increased leaf water potential, leaf area index, Soil Plant Analysis Development (SPAD) chlorophyll, net assimilation, and relative growth rate over SPV462.
Foliar application of silicon at different growth stages alters growth and yield of selected wheat cultivars
F foliar application of silicon especially at the tillering + anthesis stages was very effective in promoting resistance in wheat plants to drought conditions by maintaining cellular membrane integrity and relative water content, and increasing chlorophyll content.
Influence of Silicon Fertilization on Maize Performance Under Limited Water Supply
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. A pot experiment
Silicon fertilization improves the maize (Zea mays L.) performance under limited moisture supply
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
Role of Silicon in Mitigating Effects of Deficit Irrigation on Production of Sorghum (Sorghum Bicolor L.) Under Arid Land Conditions
Folliar application of silicon mitigated and alleviated the harsh conditions created by drought stress on sorghum plant growth and gives higher yields than 100% irrigation and optimum moister level in the root zoon.
Response of maize (Zea mays L.) to potassium nano-silica application under drought stress
Abstract To investigate the influence of potassium nano-silica (PNS) on maize plant under drought stress including non-stress (NS), moderate drought stress (MDS) and severe drought stress (SDS), a
Silicon application to drought stressed maize plants was better to improve the growth and dry matter could be attributed to improved osmotic adjustment, photosynthetic rate and lowered transpiration.
Silicon Fertilization Improves Physiological Responses in Sugarcane Cultivars Grown Under Water Deficit
There are few results about association Si and water deficit in sugarcane plants, regarding physiological aspects. The objective of this study was to investigate the effects of Si fertilization and
Beneficial Effects of Silicon on Water Stress Tolerance in Maize (Zea mays L.) Grown in Calcareous Soil
The growth of maize (Zea mays L. cv hybrid 2031) plants were evaluated under water stress induced by decreasing soil moisture from 80% of field capacity as optimal value (control )to 40%, 50%, 60%


Effects of silicon on salinity tolerance of two barley cultivars
Abstract Added silicon (Si) could significantly enhance dry matter yields of both salt‐sensitive (Hordeum vulgare L. Kepin No. 7) and salt‐tolerant (Hordeum vulgare L. Jian 4) barley cultivars under
Phosphorus nutrition and water stress tolerance in wheat plants
The effect of phosphorus (P) nutrition and soil water availability (W) on the growth of wheat (Triticum aestivum L.) plants was studied in two pot experiments in which the drought stress was imposed, the levels of P supply, and the developmental stage of the plants at each harvest were studied.
Growth and Gas Exchange of Three Sorghum Cultivars Under Drought Stress
A field study was conducted to evaluate the drought tolerance of three sorghum [Sorghum bicolor (L.) Moench] cultivars, Gadambalia, Arous elRimal and Tabat, and quantify the physiological bases for
Growth and Photosynthetic Characteristics in Pearl Millet under Water Stress and Different Potassium Supply
Influence of supra-optimal concentrations of K on growth, water relations, and photosynthetic capacity in pearl millet under severe water deficit conditions was assessed in a glasshouse.
Effect of potassium on drought resistance of Hibiscus rosa-sinensis cv. Leprechaun: Plant growth, leaf macro- and micronutrient content and root longevity
Observations indicate that adequate K nutrition can improve drought resistance and root longevity in Hibiscus rosa-sinensis.
Effects of Silicon on Transpiration and Leaf Conductance in Rice Plants(Oryza sativa L.)
It is suggested that silicon is one of the main factors responsible for regulation of gc, but that its effect was not due to an increase in the WG.
Wheat Cultivars Respond Differently to a Drying Top Soil and a Possible Non-Hydraulic Root Signal
It was suggested that the drying top soil elicited a root signal which caused stomatal closure and reduced plant production, as the first step in the investigation of the genetic control of the production of and the response to the root signal.
Silicification in sorghum (Sorghum bicolor) cultivars with different drought tolerance.
In both the root endodermis and leaf epidermis, silicification was higher in a drought tolerant cultivar Gadambalia compared with drought sensitive cultivar Tabat and the high root endodermalsilicification might be related to a higher drought resistance.
Effects of indole-3-acetic acid and zinc on the growth, osmotic potential and soluble carbon and nitrogen components of soybean plants growing under water deficit.
Three-week old soybean (Glycine max) plants were subjected to a factorial combination of four regimes of soil matric water potential (ψm=−0·03, −0·5, −1·0 and −1·5 MPa), two levels of supplementary
