The purpose of this paper is to highlight the productive capacity of some grain sorghum hybrids in relation to the amount of green biomass and dry matter. In the experiment were tested eight commercial varieties with good yield characteristics in two different densities. These hybrids were cultivated in a field that benefited from the pedological and climatic conditions from Agronomical Research Development Station of Brăila. This area is recognized for its very productive soil but also for the heat that is present very often in the summer season. In addition to grain production that can be used for multiple purposes, the secondary production of sorghum is represented by the number of stalks, leaves and panicles separated from the grain. This amount can be used for animal feed or energy purposes. Sorghum, due to its ability to adapt and develop in areas with poor weather conditions, can represent a good option to supplement and complete some plants used for fodder purposes. Through this article it can be highlighted that for the production of a superior amount of green biomass, it is important to cultivate sorghum hybrids that are taller and with greater leaf mass. In this way, can be cultivated some varieties that have an important production of grains but also a high amount of biomass.
