Cultivated in forager purpose, Sorghum bicolor can be utilized in feeding animals in green fodder form, or after a preparation and conservation through silo – as pickled forage. Starting from these considerate in this paper we proposed to approach a serial of quantitative aspects which determine the green fodder production/plant and the interdependence between those, in 3 phenophases: 4 – Flag leaf visible in whorl, 6 – Mid - Bloom, 7 – Soft dough, at Sorghum bicolor for forage. The knowing of agrobiologic particularities in relation with environmental factors, in different stages of vegetation at Sorghum bicolor for silo, offers practical information’s especially in espouse some culture technologies.
