The present investigation is concerned with the study of the weed flora associated with wheat, Triticum aestivum at Qalubiya Governorate, about 25 km north east of Cairo, Egypt. The study extended from December 2000 to April 2001. Field studies were carried out at 15 days time intervals, the average density, fresh weight and dry weight of the identified weed species were estimated. The average of five quadrats (each of a square meter area) was obtained. Meanwhile, the average height of 20 individuals of wheat plants was regularly recorded. During the growing season of the crop, the prevailing temperature seemed to be appropriate for emergence of the annual winter weed seedlings such as Sonchus oleraceus, Cichorium pumilum, Avena fatua and others.The tremendous perennial, Convolvulus arvensis dominated throughout the growing season of the wheat crop. The floristic composition of the emerged seedlings was followed during the study period. The applied reduced tillage operation was carried out only once ( 51 days after sowing ) throughout the crop growing season. This had its influence on the types of emerged species as well as on their distribution along the field.
