James Edward Smith (botanist)
__NOTOC__ Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He displayed a precocious interest in the natural world. During the early 1780s he enrolled in the medical course at the University of Edinburgh where he studied chemistry under Joseph Black and natural history under John Walker. He then moved to London in 1783 to continue his studies. Smith was a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith bought the collection for the bargain price of £1,000. The collection arrived in London in 1784, and in 1785 Smith was elected Fellow of the Royal Society. Academic career Between 1786 and 1788 Smit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Pathology
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungus, fungi, oomycetes, bacterium, bacteria, plant virus, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other Plant defense against herbivory, pests that affect plant health by eating Plant tissue, plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, wat ...

Psychoactive Plant
Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work: Psychoactivity may include sedative, stimulant, euphoric, deliriant, and hallucinogenic effects. Several hundred psychoactive plants are known. Some popular examples of psychoactive plants include '' Coffea arabica'' (coffee), '' Camellia sinensis'' (tea), ''Nicotiana tabacum'' (tobacco), and ''Cannabis'' (including hashish). Psychoactive plants have been used ritually (''e.g.'', peyote as an entheogen), medicinally (''e.g.'', opium as an analgesic), and therapeutically (''e.g.'', cannabis as a drug) for thousands of years. Hence, the sociocultural and economic significance of psychoactive plants is enormous. Examples of psychoactive plants In the table below, a few examples of significant psychoactive plants and their effects are shown. For further examples, see List of psychoactive plants.

Synthetic Cannabinoids
Synthetic cannabinoids are a class of designer drug molecules that bind to the same receptors to which cannabinoids (THC, CBD and many others) in cannabis plants attach. These novel psychoactive substances should not be confused with synthetic phytocannabinoids (THC or CBD obtained by chemical synthesis) or synthetic endocannabinoids from which they are in many aspects distinct. Typically, synthetic cannabinoids are sprayed onto plant matter and are usually smoked, although they have also been ingested as a concentrated liquid form in the US and UK since 2016. They have been marketed as herbal incense, or "herbal smoking blends", and sold under common names like K2, spice, and synthetic marijuana. They are often labeled "not for human consumption" for liability defense. A large and complex variety of synthetic cannabinoids are designed in an attempt to avoid legal restrictions on cannabis, making synthetic cannabinoids designer drugs. Most synthetic cannabinoids are agonists of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andropogon Gayanus
''Andropogon gayanus''. commonly known as gamba grass, Rhodesian blue grass, tambuki grass, and other names, is a species of grass native to most of the tropical and subtropical savannas of Africa. History and naming ''Andropogon gayanus'' was recognised and named by 1833. Its common names include gamba grass, bluestem (Africa, Australia); Rhodesian andropogon (southern Africa); Rhodesian blue grass (Zimbabwe); onga, tambuki grass (north-west Africa); and sadabahar (India). Description This tufting perennial bunchgrass can grow tall and in diameter, and has hairy leaves. Most of its roots are fibrous, spreading close to the surface of the soil for up to , but it also has thick cord roots which store starch and anchor the plant as well as vertical roots able to extract water from a greater depth during the dry season. It produces large numbers of light, fluffy seeds (up to 244,000 seeds each year, with 65% viability), which can be spread by wind, animals or m ...

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Companion Planting
Companion planting in gardening and agriculture is the planting of different crops in proximity for any of a number of different reasons, including pest control, pollination, providing habitat for beneficial insects, maximizing use of space, and to otherwise increase crop productivity. Companion planting is a form of polyculture. Companion planting is used by farmers and gardeners in both industrialized and developing countries for many reasons. Many of the modern principles of companion planting were present many centuries ago in forest gardens in Asia, and thousands of years ago in Mesoamerica. History In China, mosquito ferns (''Azolla'' spp.) have been used for at least a thousand years as companion plants for rice crops. They host a cyanobacterium (''Anabaena azollae'') that fixes nitrogen from the atmosphere, and they block light from plants that would compete with the rice. Companion planting was practiced in various forms by the indigenous peoples of the Americas pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. Lives ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *'' Agrostis'' spp. – bentgrasses **''Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *''Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *'' Bothriochloa bladhii'' – Australian bluestem *''Bothriochloa pertusa'' – hurricane grass *''Brachiaria decumbens'' – Surinam grass *''Brachiaria humidicola'' – ...

Pest (organism)
A pest is any animal or plant 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; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales.
