Question: Sorghum × drummondii is a type of grass harvested for what type of edible fruit?

full_context: Document 1: Sorghastrum nutans: Sorghastrum nutans, commonly known as either Indiangrass or yellow Indiangrass, is a North American prairie grass found in the central and eastern United States and Canada, especially in the Great Plains and tallgrass prairies.
Document 2: Rice: Rice is the seed of the grass species "Oryza sativa" (Asian rice) or "Oryza glaberrima" (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production (rice, 741.5 million tonnes in 2014), after sugarcane (1.9 billion tonnes) and maize (1.0 billion tonnes).
Document 3: Sporisorium sorghi: Sporisorium sorghi is a species of fungus in the Ustilaginaceae family. It is a plant pathogen, causing covered smut of "sorghum" spp. such as "Sorghum bicolor" ("S. vulgare") (sorghum), "S. sudanense" (Sudan grass), "S. halepense" (Johnson grass) and "Sorghum" "vulgare" var. "technichum" (broomcorn).
Document 4: Echinochloa crus-galli: Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur (or cockspur grass), barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass" (which may refer to any species of "Echinochloa" or the genus as a whole however). This plant can grow to 60" (1.5 m) in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.
Document 5: Nepalese sorghum: Sorghum (Sorghum bicolor) comes from the Latin name “Syrucum (granum)” which means “grain of Syria” however it originated in eastern Africa. Sorghum is an important species of the grass family, Paceae, and is considered the world’s fifth most important cereal crop. There are many diverse and wild types of Sorghum, however there are seven basic races, the most common in Asia are Durra and Sballu. Sorghum is an important staple crop for more than 500 million people in sub-Saharan Africa and South Asia, including many people in Nepal. Sorghum is grown on more than 48 ha area around the world. In statistics collected from 1992-1994 about general millet, Nepal had an area of 0.21 million ha, with a yield rate of 1.14 (t/ha), and produced around 0.24 million tons of Sorghum. The entirety of the crop is highly valued, both the grain and the stem are very useful. Sorghum can be cooked in many different ways for food with a high nutritional content, among many other uses. Overall Sorghum is a very important crop worldwide.
Document 6: Cereal: A cereal is any grass cultivated for the edible components of its grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. Edible grains from other plant families, such as buckwheat (Polygonaceae), quinoa (Amaranthaceae) and chia (Lamiaceae), are referred to as pseudocereals.
Document 7: Moringa oleifera: Moringa oleifera is the most widely cultivated species of the genus "Moringa", which is the only genus in the family Moringaceae. English common names include: moringa, drumstick tree (from the appearance of the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben oil tree, or benzoil tree (from the oil which is derived from the seeds). It is a fast-growing, drought-resistant tree, native to the southern foothills of the Himalayas in northwestern India, and widely cultivated in tropical and subtropical areas where its young seed pods and leaves are used as vegetables. It can also be used for water purification and hand washing, and is sometimes used in herbal medicine.
Document 8: Sorghastrum secundum: Sorghastrum secundum is a species of grass known by the common name lopsided Indiangrass. It is native to the southeastern United States.
Document 9: Sorghum × drummondii: Sorghum" × "drummondii (Sudangrass), is a hybrid-derived species of grass raised for forage and grain, native to tropical and subtropical regions of Eastern Africa. The plant is cultivated in Southern Europe, South America, Central America, North America and Southern Asia, for forage or as a cover crop.
Document 10: Sorghum bicolor: Sorghum bicolor, commonly called sorghum ( ) and also known as great millet, durra, jowari, or milo, is a grass species cultivated for its grain, which is used for food, both for animals and humans, and for ethanol production. Sorghum originated in northern Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth most important cereal crop after rice, wheat, maize and barley. "S. bicolor" is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for foliage, syrup production, and ethanol; they are taller than those grown for grain.
Document 11: Sweet sorghum: Sweet sorghum is any of the many varieties of the sorghum grass whose stalks have a high sugar content. Sweet sorghum thrives better under drier and warmer conditions than many other crops and is grown primarily for forage, silage, and syrup production. Although, in most of the United States the term "molasses" refers to a sweet syrup, made as a byproduct of sugarcane or sugar beet sugar extraction, sweet sorghum syrup is known as "sorghum molasses" in some regions of the U.S
Document 12: Rye: Rye ("Secale cereale") is a grass grown extensively as a grain, a cover crop and a forage crop. It is a member of the wheat tribe (Triticeae) and is closely related to barley (genus "Hordeum") and wheat ("Triticum"). Rye grain is used for flour, rye bread, rye beer, crisp bread, some whiskeys, some vodkas, and animal fodder. It can also be eaten whole, either as boiled rye berries or by being rolled, similar to rolled oats.
Document 13: Maize: Maize ( ; "Zea mays" subsp. "mays", from Spanish: "maíz" after Taíno "mahiz"), also known as corn, is a large grain plant first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces separate pollen and ovuliferous inflorescences or ears, which are fruits, yielding kernels or seeds.
Document 14: Gruel: Gruel is a type of food consisting of some type of cereal—oat, wheat or rye flour, or rice—boiled in water or milk. It is a thinner version of porridge that may be more often drunk than eaten and may not need to be cooked. Historically, gruel has been a staple of the Western diet, especially for peasants. Gruel is often made from millet, hemp, barley or, in hard times, from chestnut flour or even the less bitter acorns of some oaks.
Document 15: Sorghastrum: Sorghastrum is a genus of grasses, native to Africa and the Americas.
