To assess the effect of Faba bean plant density on pod depth, grain yield and seed weight 

• Increasing plant density from 10 to 40 plants/m² increased the lower pod height from 30 to 41 cm and the upper pod height from 70 to 85 cm (measured only at Ganmain).
• There was close to a 1 t/ha yield increase at Ganmain where plant density increased from 10 to 20 plants/m² (65 to 130 kg/ha seeding rate), with no further yield response to higher plant densities.
• There was no difference in grain yield with plant density ranging from 20 to 40 plants/m² at Caragabal.
• Grain size increased as plant population increased at Ganmain but there was no difference in grain size across the plant populations at Caragabal.
