TURK, M. A. | TAWAHA, A. M.
A 2-year field study was conducted during the rainy seasons of 1999 and 2000 at Houfa in northern Jordan, to study the performance of two wheat cultivars ACSAD 65 and F8 and their response to hand weeding (practised monthly during the growing seasons) and 2,4-D application at different growth stages. In both growing seasons, no significant differences (P≤0.05) in grain yield were recorded between the cultivars studied. Differences in weed number and fresh weight were significant between the various treatments in both seasons. Hand weeding proved the best method of weed control. In both growing seasons, yield reductions occurred when 2,4-D was applied to wheat, irrespective of the stage of application. Hand weeding treatment was more effective than 2,4-D application in suppressing weed growth.
