The effects of different sowing depths ranging from 50-350 mm on the establishment and productivity of an autumn sown determinate population of faba bean (858) were investigated at the University of Nottingham, UK, in 1986-89 seasons. Higher mean temperatures with increasing depth in the soil promoted more rapid germination of the deeper sown seed which resulted in similar rates of emergence for seeds sown at all depths. Plant populations were reduced, however, at the shallowest sowing depth in 1988/89 season because the seeds were eaten by birds. Yields were unaffected by sowing depth, although it is suggested that plants were less vigorous when the seed was sown more deeply
