Abstract
Wheat (Triticum aestivum L.) is a staple food of Pakistan and constitutes 60% of the daily diet of a human being in Pakistan. Production of wheat can be improved by using marginal lands and the salt affected areas by silicon supplementation and improving fertilizers. As Nanotechnology has brought revolutions in agriculture, therefore silica nanoparticles (SiO2 Nps) have been used in this study to reduce the salinity stress. Seeds of four wheat varieties, Umeed and Raskoh (salt tolerant) and Zarghoon and Shahkar (salt sensitive) were grown in Hydroponics. Hoagland’s Nutrient Solution (HNS) was used as control while treatments included CRF (Controlled Release Fertilizer), CRF with SiO2 Nps, sodium silicate, SiO2 Nps and silicic acid. Salt stress of 100 mM NaCl was induced. Data was recorded for TDS, germination rate, length of root and shoot, fresh and dry weight and chlorophyll content. All results were statistically significant at 0.05 level, sodium silicate and SiO2 Nps were found to control salinity. Excellent results were achieved using CRF and CRF containing SiO2Nps. It has been concluded that SiO2 Nps or its CRF can be useful to compete the salinity and drought stress for growing wheat in the marginal and salt affected land in Pakistan.
