Food crops
Agricultural products are products made from plants. They include the food crops, industrial crops, and fiber crops. The list of different crop types is explained below.
The food crops are the main source of food for humans. They consist of vegetables, grains, fruits, and legumes. These products are usually harvested for human consumption, but they are also sold in the international market.
Aside from food crops, the industrial plants are also classified as cash crops. They are used for a variety of purposes such as fuel, cosmetics, and paper products. They can also be used for biopolymers.
Oil crops are another type of crop. These produce oils, paints, and other materials. They are also used for manufacturing machine lubricants. These products are harvested in the form of a ratoon or stubble. They are then sprayed with pesticides to reduce the damage caused by insects.
There are many risks associated with cash crop farming. These include price fluctuations, soil degradation, and quality of produce. Some diseases and insect pests can deplete yields and reduce the amount of food available.
Food crops are generally produced in small farms, owing to the low levels of production and replacement. They are subject to attacks by insects, rodents, fungi, and diseases. These crops are also subject to changes in climate.
The majority of store-bought foods started out in the food crop category. The list of foods that are food crops includes grains, nuts, dried beans, fruits, and herbs. These plants are often considered as staples of the diets of affluent countries. Some of these crops are endangered. They are also popular luxury foods.
The major staple crops of the world are frequently deficient in some nutrients. They are a valuable source of vitamins, minerals, and roughage.
Feed crops
GE crops, also known as feed crops, are a group of plants that are engineered to meet the nutritional requirements of livestock. They are typically grown in fields and meadows. They are generally harvested dry and used as silage and green feed.
GE crops have been widely used by food producing animals for 15 years. They have been associated with considerable trade uncertainty and delays in regulatory approval. A large field data set shows that animal agriculture has not had any health effects related to GE crops. However, more studies will be needed.
Currently, most of the food that is consumed by humans is derived from crops. The agricultural industry is very dependent on GE crops. In 2012, 17.3 million farmers grew a genetically engineered crop. During that year, 195 million tonnes of corn were produced.
A number of GE crops have been approved for import into the EU. In 2012, 70% of soybean meal, 93% of soybeans, and 88% of corn in the US were GE varieties.
Since commercialization of GE crop varieties has been associated with significant regulatory costs, all but the largest corporations have found it prohibitively expensive. The EU does not provide a tolerance threshold for unapproved GE events.
Considering the high costs of commercialization, the best approach is to ensure that GE crops are not causing new risks to human or animal health. This can be achieved by designing long-term multigenerational studies to address biologically-relevant questions. These studies should be hypothesis-driven based on novel traits.
The European Food Safety Authority recently questioned the need for animal feeding studies. There are a number of reasons for this. One of the main issues is that rDNA fragments have never been detected in animal feed or products derived from animals fed GE feed. In addition, long-term animal feeding studies will likely be more costly.
Ornamental crops
Generally speaking, ornamental crops are plants grown for decorative purposes. This includes flowers, trees, shrubs, and foliage. They are considered to be a specialized branch of horticulture. They have been the early targets of GM research.
These projects target agronomic and quality traits that are important for the market chain. They are also intended to protect plant diversity.
Ornamental crops are categorized into several groups: cut flowers, nursery stock, potted flowers, and shrubs. Each group has its own set of crop interception values for different growth stages.
Genetic engineering has been applied to ornamental crops. The earliest applications of GM to this sector involved introducing a biosynthetic gene from another species. This has progressed to the commercial release of new GM cultivars.
Recent biotechnological techniques have helped preserve ornamental diversity. These methods include preserving pollen and embryos.
The preservation of ornamental diversity is a continuous process. It is triggered by changes in the design of gardens and commercial exploration of flowering crops. In order to meet the demand for ornamental crops, it is essential to store and protect ornamental germplasm.
The aesthetic value of ornamental crops is dependent on shape, color, fragrance, and uniformity of blooming. The postharvest life of ornamental plants is also a factor. Proper cultivation and postharvest treatments can help ensure that quality is maintained.
Many ornamental crops are produced from shoot tip cuttings. These cuttings form adventitious roots.
Managing the early growth stage is a key factor in the success of ornamental crops. This can be done by providing supplemental lighting during low light periods of the year. It is also important for overall quality and yields.
Ornamental plants require special skills for proper root arrangement. They respond well to silver thiosulfate.
Fiber crops
Despite the proliferation of plastics and synthetic fibers, the humble plant fiber still holds a starring role in many products and uses. Among the most important is the flax. Its fibrous seeds are used to produce linen, a staple in many homes. It is also a good source of antioxidants.
Its thorny weedy cousin, the hemp plant, is not to be confused with jute. The latter is produced in Thailand and India and is a fairly biodegradable material. It has many applications, from paper to rope to sailcloth for ships. Its tensile strength is impressive. It is not a bad idea to grow it in your backyard.
There is some debate over the efficacy of the plant and the potential health and environmental benefits it could bring to rural communities. For example, hemp produces a small crop that is highly resilient to pests and disease and can be grown in a variety of climates. This makes it a viable option for agricultural land that is currently unsuitable for crops.
The best known fiber crop is cotton, but it is not the only one. Other crop related to fiber include hemp, kenaf and flax. While cotton is by far the most productive and the most widely cultivated fiber crop, it has some significant drawbacks. In addition to its relatively high cost of production, its harvest is not always free of pests and disease. It also has poor early season vigor. The crop has a lot to offer, however, and understanding its development is critical for a sustainable future.
Other notable fiber crops include bamboo and nettle. Although not as widely cultivated as cotton, these plants have made significant contributions to the world’s supply of paper, rags and other fibers.
