Abstract:

The research was conducted in Hama Scientific Agricultural Research Center, Hama, Syria, during three growing seasons (2010/2011, 2011/2012 and 2012/2013), and in farmer’s field during the growing season (2010/2011), with the aim to identify the best seeding rate of durum wheat variety Cham3 in climatic zone B in Hama. The experiment was designed using randomized complete block design with three replications. Data analyses were done, and least significant difference (LSD) test at 5% was applied for comparison of means.  The results of three seasons showed no significant differences among the three seeding rates (150, 200 and 250 kg/ha), the best grain and biological yields were obtained by using 150 kg/ha. The combined analysis of the two sites clarified that the seeding rate of 150 kg/ha surpassed 250 kg/ha seeding rate in biological yield. As the seeding rate of 150 kg/ha for Cham3 was the best to be applied in climatic zone B in Hama Governorate, so no need to increase the seeding rate at farmer’s field over recommended seeding rate.

Keywords: Durum wheat; Seeding rates, Grain yield, Biological yield.
