Farms are households which produce goods on a large scale and must meet certain criteria for production scale and output in agriculture, forestry and fishing.
Currently, according to Circular No. 27/2011/TT-BNNPTNT dated April 13, 2011 of the Ministry of Agriculture and Rural Development on “Criteria and procedures to grant certificate of farm economy”, individuals and households who engaged in agricultural, forestry or aquaculture production with the certification of farm economy standards must satisfy the following conditions:
For cultivation, aquaculture and integrated production establishments, their farming area must be over the limit (3.1 ha for the Southeast and the Mekong River Delta, 2.1 ha for the remaining provinces) and production value of goods reaches VND 700 million per year;
For livestock establishments must reach the output value of goods at VND 1 billion/year and over;
For forestry production establishments must have a minimum area of 31 ha and average output value of goods at VND 500 million per year and over.
Perennial plants are those growing and giving products in many years, including industrial plants (tea, coffee, rubber etc), fruit plants (orange, lemon, longan, etc), and medical plants (cinnamon, etc).
The area of perennial crop is the area of agricultural crops growing from the planting time to the first time of harvesting for one year and over and harvests products for many years, including industrial crops (tea, coffee, rubber, etc.), fruit trees (oranges, lemons, longans, etc.), medical plants (cinnamon, beans, etc.).
Current area of perennial crops only recorded for the area of crops that are still alive at the time of observation, including the area of concentrated cultivation and the area converted from area of scattered trees having products to the concentrated area.
Annual plants are those growing only within a year, including grain plants (rice, maize, millet, wheat, etc), industrial plants (sugar-cane, rush, etc), medical plants, and vegetables.
Annual planted area is the planted area with agricultural crops which the growth period do not exceed one year from planting time to harvest, including cereal crops (rice, maize, millet etc.), industrial crops (sugarcane, rush, jute, etc.), medical plants, food crops and legumes.
Annual planted area is recorded when the plant starts its growing process for each cropping season. In case that in the same area where crops are replanted many times due to being dead, the area is also recorded once time.
Production of agricultural crops is the total volume of the main product of a certain agricultural crop or group of agricultural crops obtained in a cropping season or in a year of an agricultural production unit or a region/ geographical area.
Production of each type of agricultural crops is determined by the form of the product. For products such as rice, maize, green beans, soybeans, etc. are recorded in the form of dry grain; sweet potatoes, potatoes, cassava are recorded in form of fresh bulbs; tea in form of fresh buds, coffee in form of dry kernel, rubber in form of dried latex, fruits in form of fresh fruits, etc.
Yield of agricultural crops refers to the main product per one area unit of a certain agricultural crop or group of agricultural crops actually harvested in a production season or in a year on average planted area.
- There are two kinds of yield of annual crops:
| Sown yield | = | Harvested production |
|
Sown area |
| Harvested yield | = | Harvested production |
|
Harvested area |
- Two kinds of yield of perennial crops are:
| Yield in productive area | = | Harvested production from productive area |
|
Total productive area |
| Harvested yield | = | Harvested production from harvested area |
|
Total harvested area |
Harvested area: An indicator refers to the total cultivated/planted area of a certain crop or group of crops in a year, from which the crop production is reached at least 30% of yield of the ordinary year. For annual crops, harvested area is equal the cultivated area minus complete loss area; for perennial crops, it is equal productive area minus complete loss area.
Production of cereals include output of paddy, maize, and others grain crops such as wheat, millet, kaoliang, etc. produced in a given period of time. This indicator does not include production of starchy root crops.
Production of paddy (also known as production of paddy in basket) is the clean and dried paddy output of all crops in the year. The paddy output of a year is valid for that year, excluding loss during harvest, transport, and threshing, etc. (destroyed by mice, loss in fields, damage before storage).
Production of maize is the output of clean and dried maize harvested during the year.
Production of starchy root crops refers to the output of cassava, sweet potatoes, winged yam, taro, edible canna, and other starchy root crops produced in a given period.
The number of livestock, poultry and other domestic animals is the number of heads of livestock, poultry or others alive in the process of livestock production at the time of enumeration, including:
Number of livestock includes total existing number of buffaloes and cattle at the time of observation (including the newly born cattle within 24 hours); total number of existing pigs, including pigs for pork; sows and boars (excluding piglets); other livestock, including horses, goats, sheep, deer, rabbits, dogs, etc. at the time of observation;
Total number of poultry includes number of chickens, ducks, perching ducks and goose raised for food and eggs and others including total number of quail, pigeons, ostriches, etc. at the time of observation;
Number of other domestic animals includes number of bees, pythons, snakes, etc. at the time of observation.
Main livestock production is the volume of major livestock (cattle, poultry and other domestic animals) produced by cultivation activity and the natural growth of livestock during a given period, including:
Living weight production: refers to living weight of each kind of livestock, poultry and other domestic animals when being sold for the purpose of slaughter (sale, donation, self-consumption in the family, etc.), excluding the weight of livestock, poultry and other domestic animals to be sold for further breeding and the stunted, sick, but still being slaughtered for meat.
Output of non-slaughtered livestock products: Products obtained during the process of raising livestock, poultry and other domestic animals but not through slaughter such as milk, poultry eggs, silkworm cocoons, honey, sheep wool, deer velvet, etc.
