In order to determin the effect of irrigation water and seed retes on the seed yield of alfalfa (var.Hamedani) an expriment was carried out for Four years ( 1999-2002) in split - plot design with three replication in Chartakhteh Research Station in Shahrekord . three intervales of irrigation water (irrigation at 50 % - 70%- 90% use of avialable water) were considered as main plots and foure seed rates ( 5-10-15-20 kg/ha ) were considered as subplots. the resuts showed that: Effect of irrigation water was significant at 1% level and highest seed yield was obtained in irrigation at 50% use of avialable water with mean yield of 419.8 kg/ha. Effect of seed rates was significant at 1% level and maximum seed yield was obtained From 5 kg/ha seed rates with mean yield of 369.1 kg/ha. Effect of year was significant at 1% level and highest seed yield was obtaincd in 2000 with mean yield of 553.5 kg/ha. there was significant corrolation of seed yield and number of pod/head, seed /pod and 1000 seed weight.
