Farmer Al Falfa (also known as Farmer Alfalfa), the quintessential grizzly old farmer type, is an animated cartoon character created by American cartoonist Paul Terry.
 He first appeared in "Down On the Phoney Farm" (1915), a short Terry cartoon distributed by the Thanhouser Company.
 Next came a series of shorts produced by Terry for Bray Studios, starting with "Farmer Al Falfa's Cat-Tastrophe" (1916).
Alfalfa , Medicago sativa also called lucerne, is a perennial flowering plant in the pea family Fabaceae cultivated as an important forage crop in many countries around the world.
 It is used for grazing, hay, and silage, as well as a green manure and cover crop.
 The name alfalfa is used in North America.
 The name lucerne is the more commonly used name in the United Kingdom, South Africa, Australia, and New Zealand.
 The plant superficially resembles clover (a cousin in the same family), especially while young, when trifoliate leaves comprising round leaflets predominate.
 Later in maturity, leaflets are elongated.
 It has clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10–20 seeds.
 Alfalfa is native to warmer temperate climates.
 It has been cultivated as livestock fodder since at least the era of the ancient Greeks and Romans.
 Alfalfa sprouts are a common ingredient in dishes made in South Indian cuisine.
Alfamovirus is a genus of viruses, in the family Bromoviridae.
 Plants serve as natural hosts.
 There are currently only one species in this genus: the type species Alfalfa mosaic virus.
 Diseases associated with this genus include: mosaics.
Melasphaerula is a genus of flowering plants in the family Iridaceae, first described as a genus in 1803.
 There is only one known species, Melasphaerula graminea, native to Namibia and the Cape Province in South Africa.
Endothall or 3,6-endoxohexahydrophthalic acid is used as an herbicide for both terrestrial and aquatic plants.
 It is used as an aquatic herbicide for submerged aquatic plants and algae in lakes, ponds and irrigation canals.
 It is used as a desiccant on potatoes, hops, cotton, clover and alfalfa.
 It is used as a biocide to control mollusks and algae in cooling towers.
Cuscuta approximata is a species of dodder known by the common name alfalfa dodder.
 It is native to Eurasia and Africa, but it is also found in North America, where it is an introduced species and uncommon noxious weed.
 It is a parasitic vine which climbs other plants and takes nutrition directly from them via a haustorium.
 The dodder resembles a pile of light yellow to orange-red straw wrapped tightly around its host plant.
 It is mostly stem; the leaves are reduced to scales on the stem's surface, since they are not needed for photosynthesis while the dodder is obtaining nutrients from its host.
 It bears clusters of tiny yellowish bell-shaped flowers which are only about 3 millimeters wide.
 The dodder reproduces by seed, with each plant capable of producing over 10,000 seeds at once.
 This plant is a weed of alfalfa, clover, and tomatoes, as well as other crop plants and native flora.
 This species is sometimes treated as a subspecies of "Cuscuta epithymum".
Coumestrol is a natural organic compound in the class of phytochemicals known as coumestans. Coumestrol was first identified as a compound with estrogenic properties by E. M. Bickoff in ladino clover and alfalfa in 1957.
 It has garnered research interest because of its estrogenic activity and prevalence in some foods, including soybeans, brussels sprouts, spinach and a variety of legumes.
 The highest concentrations of coumestrol are found in clover, Kala Chana, a type of chick pea, and Alfalfa sprouts.
The blue alfalfa aphid (Acyrthosiphon kondoi), also known as bluegreen aphid, is an aphid in the superfamily Aphidoidea in the order Hemiptera.
 It is a true bug and sucks sap from leguminous plants, particularly alfalfa (known as lucerne in most countries outside North America).
Medicago is a genus of flowering plants, commonly known as medick or burclover, in the legume (Fabaceae) family.
 It contains at least 87 species and is distributed mainly around the Mediterranean basin.
 The best-known member of the genus is alfalfa ("M. sativa"), an important forage crop, and the genus name is based on the Latin name for that plant, "medica", from Greek: μηδική (πόα) median (grass).
 Most members of the genus are low, creeping herbs, resembling clover, but with burs (hence the common name).
 However, alfalfa grows to a height of 1 meter, and tree medick ("M. arborea") is a shrub.
 Members of the genus are known to produce bioactive compounds such as medicarpin (a flavonoid) and medicagenic acid (a triterpenoid saponin).
 Chromosome numbers in "Medicago" range from 2"n" = 14 to 48.
Clover or trefoil are common names for plants of the genus Trifolium (Latin, "tres" "three" + "folium" "leaf"), consisting of about 300 species of plants in the leguminous pea family Fabaceae.
 The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics.
 They are small annual, biennial, or short-lived perennial herbaceous plants.
 Clover can be evergreen.
 The leaves are trifoliate (rarely quatrefoiled (Four-leaf clover), cinquefoil, or septfoil), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx.
 Other closely related genera often called clovers include "Melilotus" (sweet clover) and "Medicago" (alfalfa or Calvary clover).
