A field trial was set up at Gomal University Research Farm, Dera Ismail Khan, Pakistan during 2007-2008 to asses the impact of press-mud on lentil yield and yield components. Four replicates of 8 treatments: control (no amendment), compound chemical fertilizer (NPK 30:60:45 kg per ha) and press-mud applied at rate equivalent to 2, 4, 6, 10, 15 and 20 tons per ha randomly allocated to field plots sown with leguminous crop lentil (Lens culinaris L.) The soil was calcareous with an alkaline pH of 8 and organic matter content of 8g per kg. The data showed that lentil yield and other plant parameters were influenced by the different rates of press-mud. Among the 8 treatments, the highest number of branches per plant (11.8 - 12.0), pods per plant (44.0 - 45.2), grains per pod (1.7 - 1.8), grain yield (768 - 799 kg per ha), dry matter yield (1168 - 1250 kg per ha) and root length (12.0 - 12.6 cm) of lentil were recorded in treatments receiving NPK or press-mud at the rate of 10 ton per ha.
