  • GIS-based assessment of groundwater quality and suitability for drinking and irrigation purposes in the outlet and central parts of Wadi El-Assiuti, Assiut Governorate, Egypt

    • Tác giả: Megahed, Hanaa A.;  Người hướng dẫn: -;  Người tham gia: - (2020)

  • The results indicate that the TDS values range between 1972 and 6217 ppm, while the concentration of trace elements (Fe++, Mn++ and Ni+) ranges between 0.05 and 0.46, 0.11 and 0.221 and 0.01 and 0.6 ppm, respectively. These results show that all groundwater samples are clearly unacceptable and inappropriate for human drinking due to their high content of total dissolved solids, trace elements and heavy metals, particularly in the majority of samples according to World Health Organization (WHO) guidelines and the Egyptian standards (Eg. St. 2007) for drinking water quality. Spatial analysis of the TDS values in geographic information system environment indicates that the salinity is hi...

  • Mitigation the adverse effect of salinity stress on the performance of the tomato crop by exogenous application of chitosan

    • Tác giả: Ullah, Naeem;  Người hướng dẫn: -;  Người tham gia: Basit, Abdul; Ahmad, Imran; Ullah, Izhar; Shah, Syed Tanveer; Mohamed, Heba I.; Javed, Shahryar (2020)

  • The data revealed that various application of salinity had a negative effect on almost all the studied parameters. Tomato plants treated with distilled water having no salinity (control) recorded maximum plant height (cm), average number of compound leaves plant−1, leaf area (cm2), stem diameter (mm), number of fruits plant−1, fruit firmness (kg cm−2), leaf chlorophyll content (SPAD), fruit juice pH, yield plant−1 (kg) and minimum total soluble solids (Brix°). Whereas, minimum plant height (cm), average number of compound leaves plant−1, leaf area (cm2), stem diameter (mm), number of fruits plant−1, fruit firmness (kg cm−2), leaf chlorophyll content (SPAD), fruit juice pH, yield plant...

  • Productivity of Quinoa (Chenopodium quinoa L.) under new reclaimed soil conditions at north-western coast of Egypt

    • Tác giả: Wali, Asal M.;  Người hướng dẫn: -;  Người tham gia: Kenawey, M. K.; Ibrahim, O. M.; Lateef, E. M. Abd El (2022)

  • Introducing new crops to reduce the nutritional gap in Egypt is an important target. One of these crops is Quinoa which is characterized by high nutritional value with multiple food uses. However, it will compete with other winter crops, so it is candidate to grow in marginal lands like calcareous soils. Meanwhile, planting density and N requirements are not known under such conditions; therefore, this work was undertaken in calcareous soil Caco3 > 50%.
