We would like to dedicate this work to all our
professors who supervised us in our early
stages of education and career. These
professors guided and assisted us until we
reached this stage of our working life. Some
of them passed away and the others are still
among us generously contributing with their
great knowledge to bring out generations of
scientific excellence.
Of these professors, we dedicate this work to
the souls of Prof. Hamadah Abd El-Maksoud
and Prof. Ahmed Said Kamel (both from
Agricultural Research Center).
We also dedicate this work to Prof. Hamdy
Khalifa (Agricultural Research Center), Prof.
Nemet Nour El-Din (Faculty of Agriculture,
Ain Shams University), and Prof. Mahmoud
Saif Osman (Faculty of Agriculture, Al-Azhar
University).
Finally, we dedicate this work to all our
colleagues who supported us physically and
emotionally.
