To evaluate the effect of sowing dates of hybrid silage sorghum Volumax, an experiment was conducted on the campus of the Universidade Federal de Lavras, Lavras/MG, in two crop years 2006/07 and 2007/08. The design was to block the case, with five treatments and three replicates with five sowing dates (October 30, November 15 and 30 and December 15 and 30). We evaluated the yield of green mass, dry mass and crude protein and levels of P, Ca, K, Mg and S in forage. The results revealed a decline in forage yield with delayed sowing date. The sowing of December 30 provided lower levels of nutrients in forage sorghum.
