Berseem clover (Trifolium alexandrinum L.) is an annual forage crop widely grown in Mediterranean environments. The accumulation of dry matter in the various plant organs, at a given growth stage, in forage legume species is a subject of biological and economic concern. The study was carried out during three growing seasons (1991-92, 1992-93 and 1993-94) at Foggia (southern Italy), with the aim of evaluating changes in the growth dynamics of one population of Egyptian (cv.'Giza 10') as well as Italian (cv.'Sacromonte') origin using field-grown plants under several cutting regimes. The harvest treatments were applied at three developmental stages of the plant: sixth internode elongation, early flowering and physiological maturity of seeds (treatments A, B and C, respectively). Seasonal growth pattern, determined as dry matter accumulation, was greatly influenced by cutting regimes. In treatment C, the maximum value (21.6 g plant-1 in the mean) was reached at about 250 days after sowing.
