A comparative Study on Some Maize Cultivars and Their Relationship to Damage Caused by Hooded Crow, Corvus corone sardonius at Qena Governorate, EGYPT

Abstract

Seven field experiments were carried out at Dahsa village, Farshout district, Qena governorate, Egypt, 2019 season to evaluate the damage caused by hooded crow, Corvus corone sardonius on seven cultivars of maize (Zea mays L.). The cultivars were Watania 4, Watania 6, Watania 11, Watania 310, Hytech 2055, Hytech 2066 and Balady. The results revealed that the highest loss was recorded in Balady cultivar (7.17%), followed by single cross Hytech 2055 and S. C. Hytech 2066 (2.50 and 2.17%) as yellow seeds of maize. Moderate loss was recorded in three way cross Watania 11 and T. W. Watania 310 (1.83 and 1.33%) as white seeds of maize. While the lowest loss was recorded in S. C. Watania 6 and S.C. Watania 4 (0.17 and 0.67%) as white seeds of maize. Generally, the highest loss was recorded in maize cultivars of yellow seeds. While, the lowest loss was recorded in maize cultivars of white seeds. So, the yellow cultivars may be preferable for cultivation than white cultivars maize, besides the high oil in yellow cultivars of maize.
