No, sorghum and sugarcane are two different plants. Sorghum is panicle-bearing, and its offspring are small round white particles, which are mainly used to produce sorghum rice noodles and make wine. Its stalk is similar to that of corn and can be used as feed and paper. Sugarcane is an edible stem with leaves on it. The roots of both have no special purpose and are used to waste materials. Sorghum, on the other hand, is slightly sweeter, with a sugar content of about 2%, which is far from the sugar content of sugarcane 15%, which can solve the thirst problem of sugarcane.
However, the first crop named "Sweet Sorghum" is also called "Second Generation Sugarcane", which is also called "Sorghum Sugarcane" because it has grains above and sugarcane below.
I hope it helps you.
