  • Effect of low gamma irradiation doses on growth, productivity and chemical constituents of Jerusalem artichoke (Helianthus tuberosus) tubers

    • Authors: Mounir, Amr M.;  Advisor: -;  Participants: El-Hefny, A. M.; El-Tanahy, A. M. M.; Mahmoud, S. H. (2022)

  • Vegetative characteristics Data presented in Table 2 show the effect of different low doses of gamma irradiation on growth characters of Jerusalem artichoke plants, and from the obtained results, it could be concluded that there was significant difference among different doses and 5 Gy of gamma irradiation scored the tallest plant, the highest number of branches, shoot fresh and dry weight as well as leaf area per plant compared to others doses during the two successive seasons, followed insignificantly by both irradiation doses 2.5 and 10 Gy. It was shown that all irradiation doses caused a remarkable amelioration of plant vegetative growth parameters compared to un-irradiated tubers.

  • 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%.

  • Effect of foliar spray of ammonium nitrate and irrigation time on vegetative growth, fruit set, yield and fruit quality of “Ewais” mango trees

    • Authors: El-Migeed, M. M. M. Abd;  Advisor: -;  Participants: El-Razek, E. Abd; Ali, Hassan A. M.; Abdel-Hamid. N. (2022)

  • The current experiment was done during the 2018 and 2019 seasons on ‘Ewais’ mango trees (Mangifera indica) grown in Research Station, El-Nubaria district, Egypt, to study the impact of spraying ammonium nitrate (NH4NO3) and irrigation time on vegetative growth, yield and fruit quality. All experimental plants have been received the same care, i.e. control of pests & weeds, fertilization, and irrigation until the 1st week of October. The irrigation was adapted to apply 5m3/feddan (4200 m2)/week to control leaves damage due to low temperature after this period and the treatments included: (T1) Water spraying at 1st week of November + start normal irrigation program at the same time after four weeks of adapted irrigation as 5m3/feddan (4200 m2)/week (Control)...
