  • Allelopathic activity of the leaf powder of Ficus nitida on the growth and yield of Vicia faba and associated weeds

    • Authors: El-Masry, R.R.;  Advisor: -;  Participants: Ahmed, S.A.A.; El-Rokiek, K.G.; Messiha, N.K.; Mohamed, S.A. (2019)

  • All concentrations used pronouncedly decreased the fresh and dry weight of both Phalaris minor and Malva parviflora. On the other hand, Vicia faba growth as well as its yield and yield components were increased with most concentrations used as compared to their mixed controls. Treatments of 20, 30, and 40 g/kg soil, from F. nitida leaf powder, respectively recorded the highest increases in the most growth characters of V. faba with both weeds (P. minor and M. parviflora) at the two growth ages when compared to the healthy control. Also, the best results in all V. faba yield components were recorded with 20 g/kg soil of F. nitida treatment.

  • Evaluating the allelopathic potentiality of seed powder of two Brassicaceae plants in controlling Orobanche ramosa parasitizing Lycopersicon esculentum Mill. plants

    • Authors: El-Masry, R.R.;  Advisor: -;  Participants: El-Desoki, E.R.; El-Dabaa, M.A.T.; Messiha, N.K.; Ahmed, Salah El-Din Abd-Elghany (2019)

  • The results indicated that no O. ramosa infestation on Lycopersicon esculentum appeared with all Essp and Sasp concentrations except with the lowest concentration (5 g/kg soil) that reduced O. ramosa tubercles dry weight at 100 days from transplanting (DFT) to about 48.4 and 42.0%, respectively, as compared to the infected control. Lycopersicon esculentum growth as well as its yield and yield components were significantly increased with Basamid treatment at 0.2 g/pot and all Essp and Sasp concentrations (5–45 g/kg soil) except some parameters with the lowest concentration (5 g/kg soil) of both materials used when compared with their corresponding infected control. The highest yield, w...
