Jatropha
''Jatropha'' is a genus of flowering plants in the spurge family, Euphorbiaceae. The name is derived from the Greek words ἰατρός (''iatros''), meaning "physician", and τροφή (''trophe''), meaning "nutrition", hence the common name physic nut. Another common name is nettlespurge. It contains approximately 180 species of succulent plants, shrubs and trees (some are deciduous, like '' Jatropha curcas''). Most of these are native to the Americas, with 66 species found in the Old World. Plants produce separate male and female flowers. As with many members of the family Euphorbiaceae, ''Jatropha'' contains compounds that are highly toxic. ''Jatropha'' species have traditionally been used in basketmaking, tanning and dye production. In the 2000s, one species, '' Jatropha curcas'', generated interest as an oil crop for biodiesel production and also medicinal importance when used as lamp oil; native Mexicans in the Veracruz area developed by selective breeding a ''Jatropha cur ...

Jatropha Oil
''Jatropha curcas'' is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics: Mexico, the Caribbean and Central and South America. It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas. The specific epithet, ''"curcas"'', was first used by Portuguese doc Garcia de Orta more than 400 years ago. Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut. In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant", but it is not the same as the usual castor oil plant, ''Ricinus communis'' (they are in the same family but different subfamilies). ''Jatropha curcas'' is a semi-evergreen shrub or small tree, reaching a height of or more. It is resistant to a high d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biodiesel
Biodiesel is a renewable biofuel, a form of diesel fuel, derived from biological sources like vegetable oils, animal fats, or recycled greases, and consisting of long-chain fatty acid esters. It is typically made from fats. The roots of biodiesel as a fuel source can be traced back to when J. Patrick and E. Duffy first conducted transesterification of vegetable oil in 1853, predating Rudolf Diesel's development of the diesel engine. Diesel's engine, initially designed for mineral oil, successfully ran on peanut oil at the 1900 Paris Exposition. This landmark event highlighted the potential of vegetable oils as an alternative fuel source. The interest in using vegetable oils as fuels resurfaced periodically, particularly during resource-constrained periods such as World War II. However, challenges such as high viscosity and resultant engine deposits were significant hurdles. The modern form of biodiesel emerged in the 1930s, when a method was found for transforming vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jatropha Podagrica
''Jatropha podagrica'' is a species of flowering, caudiciform succulent plant in the spurge family, Euphorbiaceae, aligning it closely with related genera such as ''Croton'', ''Euphorbia'' and ''Ricinus'' (castor bean), among others. It is native to the neotropics of Central America and southern Mexico, but is grown as an ornamental plant in many parts of the world due to its unusual appearance and mature caudex development. Common names for the species include gout-plant, gout-stalk, Guatemalan rhubarb, coral-plant, Buddha-belly plant, purging-nut, physic-nut, goutystalk nettlespurge, Australian bottleplant (a geographical misnomer) and tartogo. Description ''J. podagrica'' is a caudiciform perennial herb growing up to 1 metre (3 feet) tall. The grey-green, knobby, swollen caudex has a bottle-like appearance, giving rise to some of the common names. Leaves are held on long fleshy yet stout petioles which emerge from the tip of the stem and radiate in all directions. Leaves ar ...

Krameria Grayi
''Krameria bicolor'' is a perennial shrub or subshrub of the family Krameriaceae, the rhatanies. It is commonly known as white rhatany, crimson-beak, and ''chacate'' in Spanish (''cosahui'' in the state of Sonora). It is found in drier environments of the southwestern United States from California to Texas, and in northern Mexico. It is a low-lying, densely branched shrub, commonly up to , but exceptionally to beyond . The branches are spreading, with thornlike tips. The leaves are grey-green to greenish, finely-haired, narrow and only one-half to three-quarters of an inch long. The color of the plant and branches is grayish-green to gray, or whitish-gray, to dull browns or tinged with red. The flowers are often sparse and sometimes inconspicuous, but plants in some locales can bloom prolifically in red flowers. The plant is used for dyes in the basketry of Seri people in Mexico. The shrub is adapted to dry, desert environments, but it can take advantage of high soil moisture. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pest (organism)
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats and cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fertilizer
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter).
