This is an alternative crop for bioenergy and is particularly noted for its drought tolerance.
the basic question: food or fuel? It all depends on the economic and welfare state of your society!
Yes, depends on requirement, suitability and availability. Best.

Thank you very much for answers.
Probably, introduced in crop rotation (crop bioenergy/forage crops) to improve soil fertility. I think, should be a good choice sustainable and economic.
Yes, of course! Embrapa Milho e Sorgo (Corn and Sorghum) has many cultivars, to use as forages and bioenergy. https://www.spo.cnptia.embrapa.br/conteudo?p_p_id=conteudoportlet_WAR_sistemasdeproducaolf6_1ga1ceportlet&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=column-2&p_p_col_count=1&p_r_p_-76293187_sistemaProducaoId=8301&p_r_p_-996514994_topicoId=9201
Sorghum harvested as grain provides alternatives for food and biofuels. Fermentation to ethanol, when supplies are in excess, can be an economic stimulus to rural economies while increasing production efficiencies to satisfy needs. Besides providing a crop rotation alternative, an understated benefit of biofuels is that diets can be diversified. Dried by-product of fermentation concentrates protein in feed minimizing transportation while enhancing poultry, swine, and dairy rations.
Thanks you all for answers,
Maybe this crop should be utilised, in dryland with low rainfall, only as food for animals. The irrigation for biofuel production is more expensive. The choice of forage sorghum varieties is related to environmental factors. The main object of breeding could be to improve productivity (example WUE, leaf architecture, ability to regrowth to avoid further sowings).
