  • Effect of bio-stimulants foliar applications on growth, yield, and product quality of two Cassava cultivars

    • Authors: Hassan, Nagwa M. K.;  Advisor: -;  Participants: Marzouk, Neama M.; Fawzy, Zakaria F.; Saleh, Said A. (2020)

  • The results showed that American cassava cultivar recorded the highest vegetative growth characters (plant height, leaves number, main stems, lateral branches, leaf area, and chlorophyll content), tuber yield (number and weight), and tuber quality (length, diameter, dry matter, and tubers-shoots ratio) as well as chemical composition (starch, total carbohydrates, N, P, and K). The foliar application of glutamine at the rate of 200 mg/L increased vegetative growth characters and tuber yield as well as tuber quality and improved chemical contents of cassava tubers. On the contrary, the lowest values of cassava growth and its productivity as well as chemical composition were associated t...

  • Effect of different single herbicide doses on sugar beet yield, quality and associated weeds

    • Authors: Abd El Lateef, E. M.;  Advisor: -;  Participants: Mekki, B. B.; Abd El-Salam, M. S.; El-Metwally, I. M. (2021)

  • The results showed that the herbicides Betasana-Trio at 0.9 l fed−1, Tigro at 1.0 l fed−1 and Betasana-Trio at 0.675 l fed−1 when sprayed twice could effectively and/or completely eliminate the broadleaved weeds associated with sugar beet plants. Moreover, the results indicated and confirmed that Tigro and Betasana-Trio herbicides are effective in controlling broadleaved weeds. Similar tendency was recorded for the narrow-leaved weeds, where Select Super or Betanal MaxxPro at 0.5 l fed−1 as well as Select Super at 0.375 l fed−1 could completely eliminate or minimize the narrow-leaved weeds associated with sugar beet plants. The greatest significant root length, root diameters and root...

  • Effect of glutathione and/or selenium levels on growth, yield, and some biochemical constituents of some wheat cultivars grown under sandy soil conditions

    • Authors: Dawood, Mona G.;  Advisor: -;  Participants: Sadak, Mervat Sh.; Bakry, Bakry A.; Kheder, Howida H. (2020)

  • The results indicate that the Gemmeiza-11 cultivar was the most adapted cultivar to grow in the Nubaria region. Individually, glutathione at 300 mg/l or selenium at 10 mg/l caused the highest significant increases in shoot dry weight/plant of three wheat cultivars relative to other levels. Likewise, glutathione treatment at 300 mg/l was the optimum treatment in increasing photosynthetic pigments in three wheat cultivars. Selenium treatment at 10 mg/l was better than selenium treatment at 5 mg/l. Interaction between glutathione at 300 mg/l and selenium at 10 mg/l caused the highest significance increases in total photosynthetic pigments. It is obvious that glutathione at 300 mg/l or se...

  • Enhancement of antioxidant and storability of Hollywood plum cultivar by preharvest treatments with moringa leaf extract and some nutrients

    • Authors: Mahmoud, Thanaa Shaban Mohamed;  Advisor: -;  Participants: Shaaban, Fatma Korany Mohamed; El-Hadidy, Gehan Abd El-Malek (2020)

  • Plum fruit has a short shelf life with a rapid deterioration in quality after harvest. The main aim of this study was to evaluate the effect of preharvest treatments by moringa leaf extract (MLE), boric acid (B), and chelated calcium (Ca EDTA) on Hollywood plum fruit quality attributes bioactive compounds and antioxidant activity during cold storage. At the end of storage, all studied treatments exhibited significantly higher sensory quality: firmness, color, soluble solid content:titratable acidity ratio, total anthocyanin content, total flavonoids content, total phenolic content, and antioxidant activity than control.

  • 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

    • Authors: Megahed, Hanaa A.;  Advisor: -;  Participants: - (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

    • Authors: Ullah, Naeem;  Advisor: -;  Participants: 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

    • Authors: Wali, Asal M.;  Advisor: -;  Participants: 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%.
