ALFALFA 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. The English name alfalfa is widely used, particularly in North America . But in the UK, Australia, South Africa and New Zealand, the more commonly used name is lucerne. It superficially resembles clover, with clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10-20 seeds. Alfalfa is native to a warmer temperate climate such as that of Iran (where it is thought to have originated). It has been cultivated as livestock fodder since at least the era of the ancient Greeks and Romans.

Alfalfa is the most cultivated forage legume in the world . Worldwide production was around 436 million tons in 2006 . The US is the largest alfalfa producer in the world, but considerable production is found in Canada, Argentina (primarily grazed), Southern Europe, Australia, South Africa, and the Middle East. Within the United States, the leading alfalfa growing states are California, South Dakota, and Wisconsin. The upper Midwestern states account for about 50% of US production, the Northeastern states 10%, the Western states 40%, and the Southeastern states almost none. Alfalfa can be grown in the southern US states, but often leaf and root diseases and poor soils are limitations. Alfalfa has a wide range of adaptation, and can be grown from very cold northern plains to high mountain valleys, from rich temperate agricultural regions to Mediterranean climates and searing hot deserts . Worldwide production

Alfalfa is high in protein, calcium, plus other minerals, vitamins in the B group, vitamin C, vitamin D, vitamin E, and vitamin K. The sun-dried hay of alfalfa (also known as Lucerne) has been found to be a source of vitamin D, containing 48 ng /g (1920 IU/kg) vitamin D2 and 0.63 ng /g (25 IU/kg) vitamin D3 . There is reference to vitamin D2 and vitamin D3 being found in the alfalfa shoot; this is awaiting verification . Mushrooms are not allowed in Jain vegetarianism, making alfalfa the only known source Jains can use to make vitamin D2 supplements. NUTRITIONAL VALUE

ALOE VERA Aloe vera is a succulent plant species that probably originated in northern Africa. The species does not have any naturally occurring populations, although closely related aloes do occur in northern Africa.[1] The species is frequently cited as being used in herbal medicine since the beginning of the first century AD. Extracts from A. vera are widely used in the cosmetics and alternative medicine industries, being marketed as variously having rejuvenating, healing or soothing properties. There is, however, little scientific evidence of the effectiveness or safety of A. vera extracts for either cosmetic or medicinal purposes, and what positive evidence is available is frequently contradicted by other studies.

PowerPoint Presentation:

Aloe vera is a stemless or very short-stemmed succulent plant growing to 60–100 cm (24–39 in) tall, spreading by offsets. The leaves are thick and fleshy, green to grey-green, with some varieties showing white flecks on the upper and lower stem surfaces. The margin of the leaf is serrated and has small white teeth. The flowers are produced in summer on a spike up to 90 cm (35 in) tall, each flower being pendulous, with a yellow tubular corolla 2–3 cm (0.8–1.2 in) long. DESCRIPTION
