What is the definition of a weed in agriculture?
A weed is simply a plant that is growing where it is not wanted. This can include crops, native plants, and non-native species. If a plant is considered to be a nuisance, it can be termed a weed.
Amaranth, Bermuda grass, and bindweed are often considered to be weeds because they are difficult to control and can spread quickly. However, amaranth is a highly edible and resilient food source, and Bermuda grass is a popular turfgrass.
What is a weed or plant
A weed is simply a plant out of place. By this definition, any plant could be a weed if growing in a location where it is not wanted. There are some species of plants, such as thistle and poison ivy, that are rarely wanted in the lawn or garden setting and are often growing out of place.
Weeds are plants that are growing where they are not wanted. They compete with crops for water, nutrients, light, and space. These plants can contaminate products at harvest, harbor pest insects, mites, vertebrates, or be a source of plant disease agents.
What is weed very short answer?
Weeding is the process of removal of unwanted plants that grow in-between crops. Weeds compete with crops for water, sunlight and nutrients, and can therefore reduce crop yields. Hand-weeding is the most common method of weed control, but mechanical and chemical methods are also used.
The term “weed” started being used for cannabis at the start of the 20th century. It likely stems from the shortened version of the word “locoweed,” which is a species of plant that grows in Mexico. Cattle and horses would eat this plant, and it would have a strange effect on them.
What are the different types of weed in agriculture?
A weed is a plant that is considered undesirable, unattractive, or troublesome, especially one that grows in an unwanted place. Weeds are often considered to be plants that interfere with the use of a area for a desired purpose, such as gardening or farming. Some weeds can also be invasive, meaning they crowd out other plants and can be difficult to control.
Weeds are plants that are often considered unwanted in a particular location. However, some weeds can have benefits, such as providing food or habitat for wildlife. Here are 20 common weeds found in local areas:
1. Speargrass (Imperata cylindrica)
2. Siam weed (Chromolaena odorata)
3. Nutgrass (Cyperus rotundus)
4. Milkweed (Euphorbia heterophylla)
5. Nuke-Noh (Tridax procumbens)
6. Witchweed (Striga genus)
7. Couchgrass (Digitaria abyssinica)
8. Dayflower (Commelina benghalensis)
9. Common chickweed (Stellaria media)
10. Dandelion (Taraxacum officinale)
11. Plantain (Plantago major)
12. Ground ivy (Glechoma hederacea)
13. Cleavers (Gallium aparine)
14. Red sorrel (Rumex acetosella)
15. White clover (Trifolium repens)

What are the 3 types of weeds
Weeds are plants that are not wanted in a particular area. There are many different types of weeds, including:
Terrestrial weeds: Weeds that grow in land only
Aquatic/water weeds: Weeds that grow in water
Submerged weed: Weeds that grow under the water
Emerged weeds: Weeds which roots are anchored in soil underwater but some parts above the water
Weeds can be a pain to deal with, but if you take the time to identify them, you can make sure your lawn is healthy and weed-free. Here are a few things to look for when trying to identify weeds:
-Weeds are often shorter and sparser than grass
-Weeds may have different colored leaves or stems than your grass
-Weeds may be more tolerant of dry, nutrient-deficient soil than grass
If you’re not sure if you have weeds or grass, observe the overall appearance of your lawn. If it’s patchy and full of weeds, you may need to replant with grass seed. If it’s mostly grass with a few weeds, you can try to remove the weeds by hand or with a weedkiller.
How do I identify a weed?
Other distinctive characteristics that help identify some weeds include:
Presence of spines, thorns, prickles, or stinging hairs
Milky juice or sap when stem or leaves are cut
Presence of a leaf sheath surrounding the stem at each node
Stems square in cross section.
A weed, in this context, is a plant that is not intentionally sown or propagated by the grower, and which requires management to prevent it from interfering with crop or livestock production. In other words, it is a plant that can become a pest if not controlled.
Why are weeds a problem for farmers
Weeds are one of the most common problems that farmers face. They compete with crops for sunlight, water, nutrients, and space. In addition, they harbor insects and pathogens, which attack crop plants. Furthermore, they destroy native habitats, threatening native plants and animals.
Weeds can spread by sexual and vegetative methods, and can survive adverse weather conditions. They produce large numbers of seeds, and are aggressive and persistent in trampling. Some weeds mature at the same time with crops, and are harvested with crops.
What causes weeds to grow?
Weeds are often considered a nuisance because they can grow quickly and crowd out other plants. But there are actually some benefits to having weeds in your garden. Weeds can help improve the soil by adding organic matter and preventing erosion. They can also provide habitat and food for wildlife. And some weeds, like dandelions, can actually be good for your health. So next time you spot a weed, don’t reach for the herbicide. You may be doing more harm than good.
Weeds are a problem for farmers because they compete with crops for resources. Weeds can also harbour pests and diseases that can threaten a crop. In some cases, weeds can also be poisonous. Weeds are difficult to control and can quickly spread if not managed properly.
What was weed originally called
The word “marijuana” comes from the Mexican Spanish word for the cannabis plant. Other early variants include “mariguan” (1894), “marihuma” first recorded in 1905, “marihuano” in 1912, and “marahuana” in 1914. According to the second edition of Webster’s New International Dictionary, the word originally denoted a species of South American wild tobacco, Nicotiana glauca.
Dope is a term that has evolved over time to mean different things. In the 1960s, 1970s, and 1980s, dope was synonymous with marijuana. However, in more recent years, the term has come to mean any illegal drugs, not just marijuana. This evolution in the meaning of the term is likely due to the ever-changing drug landscape and the need for a more general term to describe all illegal drugs.
Final Words
A weed is a plant that is not valued where it is growing, and is usually of a competing species.
A weed is a plant that is not wanted in a particular place. In agriculture, weeds are unwanted plants that compete with crops for water, sunlight, and space. Weeds can be difficult to control and can reduce crop yields.
