Abstract
A field experiment was conducted at the Research Site of Tehran Province, Iran to study the effect of different seeding rates on seed yield and seed yield components of alfalfa during 2005-2008 growing seasons. Seeding rate treatments were 2.5 kg ha (SR ), 5.0 kg ha (SR ), 7.5 kg ha (SR ), 10.0 kg ha (SR ) and 12.5 11 1 1 123 4 kg ha (SR ). Seed yield and seed yield components, i.e. number of pods per unit area, number seeds per pod 1 5 and 1000-seed mass were determined for all treatments. The statistical results of the study indicated that seeding rate significantly (P = 0.01) affected seed yield and number of pods per unit area, but there was no significant difference in number seeds per pod and 1000-seed mass. The maximum value of seed yield (805.0 kg ha ) and number of pods per unit area (6610) was obtained in case of SR treatment. On the other hand, the 1 1 minimum value of seed yield (605.7 kg ha ) and number of pods per unit area (4620) was observed in case of 1
