Barley was among the first grains to be grown in Eurasia about 10,000 years ago. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Massive swarms of locusts are sweeping across South Asia, the Middle East and the Horn of Africa. Crops that grow in Asia include rice, wheat, barley and tropical fruits such as litchi and pineapple. The traditional method of irrigation in Asia is by gravity water flow. Anthers detached from a meadow foxtail flower, "Grass" redirects here. Barley (Hordeum vulgare L.) is a member of the grass family and it is a primary cereal grain that is cultivated throughout the world in regions with temperate climates. Humans get an average of 48 percent of their calories, or food energy, from grains. In tennis, grass is grown on very hard-packed soil, and the bounce of a tennis ball may vary depending on the grass's health, how recently it has been mowed, and the wear and tear of recent play. My children are healthy. [citation needed] Reeds are used in water treatment systems, in wetland conservation and land reclamation in Afro-Eurasia. Grain is the harvested seed of grasses such as wheat, oats, rice, and corn.Other important grains include sorghum, millet, rye, and barley.Around the globe, grains, also called cereals, are the most important staple food. 18. Pseudocereals are foods that can be used like grains, but come from plants that aren't related to the Grass Family. [11][12] In 2011, revised dating of the origins of the rice tribe Oryzeae due to findings from the same deposit suggested a date as early as 107 to 129 Mya. [17][18] Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. There are about 12,000 grass species in about 771 genera that are classified into 12 subfamilies. [30], Grass on golf courses is kept in three distinct conditions: that of the rough, the fairway, and the putting green. The term âFood cropsâ refers to plants,which provide food for human consumption, cultivated by man by agriculture.they mainly constitute of Cereals,Legumes,vegetables,tubers and fruits. [28] Cereals constitute the major source of carbohydrates for humans and perhaps the major source of protein, including rice (in southern and eastern Asia), maize (in Central and South America), and wheat and barley (in Europe, northern Asia and the Americas). The stems of grasses, called culms, are usually cylindrical (more rarely flattened, but not 3-angled) and are hollow, plugged at the nodes, where the leaves are attached. If only large, contiguous areas of grasslands are counted, these biomes cover 31% of the planet's land. [13], Wu, You & Li (2018) described grass microfossils extracted from a specimen of the hadrosauroid dinosaur Equijubus normani from the Early Cretaceous (Albian) Zhonggou Formation (China), which were found to belong to primitive lineages within Poaceae, similar in position to the Anomochlooideae. In most Asian countries, particularly in the low income countries of South Asia, per-capita food availability has risen. Three general classifications of growth habit present in grasses: bunch-type (also called caespitose), stoloniferous, and rhizomatous. Grasses are unusual in that the meristem is near the bottom of the plant; hence, grasses can quickly recover from cropping at the top. Commercial agriculture. Depending on location and cultivar, either its stalks, leaves or hypocotyl are eaten and used in cooking. Such grasses may be cut and stored for later feeding, especially for the winter, in the form of bales of hay or straw, or in silos as silage. For example, members of the Fabaceae (legume family) can be grown to add nitrogen to the soil and many members of the Liliaceae are heavy users of potassium. They aren't technically grains. Bananas resistant to bacterial wilt and nematodes Genetically modified bananas resistant to bacterial wilt are shown on the left (image A), while Non-GM bananas are shown on the right. Trampling grazers kill seedling trees but not grasses.[20]:137. Wheat, barley, and rye are all members of the same tribe (Triticeae) within the family Poaceae. Sustainable Agriculture Farming methods that preserve long-term productivity of land and minimize pollution, typically by rotating soil-restoring crops with cash crops and reducing inputs of fertilizer and pesticides. For other uses, see, Family of flowering plants commonly known as grasses. This low growth point evolved in response to grazing animals and allows grasses to be grazed or mown regularly without severe damage to the plant.[20]:113–114. Most characteristic of developing countries. Poaceae, formerly called Gramineae, grass family of monocotyledonous flowering plants, a division of the order Poales. The relationships among the three subfamilies Bambusoideae, Oryzoideae and Pooideae in the BOP clade have been resolved: Bambusoideae and Pooideae are more closely related to each other than to Oryzoideae.
