In order to determine the effects of different phosphorus and seed rates on grain yield of lentil (Lens culinaris Medik.) in dryland condition, this experiment was conducted from 2000 to 2003 in in Maragheh, Sararoud and Gachsaran dryland agricultural research stations. The experiment was arranged with RCBD factorial design with three phosphorus fertilizer rates (0, 30 and 60 kg P2O5.ha-1) and 3 seed rates (100,200 and 300 seed.m-2) with four replications. In Maragheh, the results showed that increasing phosphorus did not increase grain yield significantly,but seed rates increased grain yield significantly(P%1),where the most yield ( 477kg.ha-1) obtained from 200 seed.m-2. In Sararoud the results showed that seed rates increased grain yield significantly(P%1),but phosphorus effects was not significantly different, where the most yield (1072kg.ha-1) obtained from 300 seed.m-2.In Gachsaran the results showed that phosphorus increased grain yield significantly,and also seed rates and their intraction effects were significantly (P%1) different. Intraction of 60 kg P2O5.ha-1 and 200 seed.m-2 produced maximum grain yield (2073 kg.ha-1). It can be concluded that lentil grain yield differed at different levels of seed rates in all places.However, phosphorus fertilizer did not increase grain in Maragheh and Sararoud.
