Field experiments were conducted during the winter seasons of 1998-1999, 1999-2000 and 2000-2001 at the semi-arid region in north of Jordan, to study the effect of seeding dates (14 January, 28 January and 12 February), seeding rates (50, 75 and 100 plants per metre), phosphorus levels (0, 17.5, 35.0 and 52.5 kg P per ha) and two methods of P placement (banding and broadcast). Seeding rate, seeding date, and rate of phosphorus had a significant effect on most of the measured traits and the yield determinates. Method of phosphorus application had only a significant effect on seed yield and seed weight per plant. In general high yields were obtained by early seeding (14 January), high seeding rate (100-plant per square metre), and P application (52.5 kg P per ha) drilled with the seed after cultivation (banded).
