Early estimation-wheat, barley. The evaluation is performed by specialists-agronomists who visit sampled segments of arable land where wheat and barley points are observed. The aim is to determine the potential yield of wheat and barley before harvest. Survey on land cover and land use of the territory of Bulgaria. At the municipality level, the operational information is collected by farmers on the area and production of main crops for the current year (during the harvest) is collected by employees of the Ministry of Agriculture and Food, and Table 1 is filled with the data until January of the following year (n+1). Preliminary data from the statistical sample survey of field crop yields shall be used to complete Table 1 no earlier than March n+1. |

Additional information |
The farmers provide moisture content data on cereals, dried legumes and oilseeds. For the plants harvested green, the collected data shows the way of harvest (hay or fresh ) and the experts estimate the required humidity. |

Which method is used for calculating the yield for main arable crops? |
production divided by harvested area |
If another method, describe it. |

Definitions |
Question |
In case yes, how do they differ? |
Do national definitions differ from the definitions in Article 2 of Regulation (EC) No 543/2009? |
YES |
Table 3 shows the production area only, with the exception of young trees, witch are not included. And area from which production was not harvested due to climatic and other reasons (non-practical agroecology, economic reasons, temporarily abandoned plantations). |
Are there differences between the national methodology and the methodology described in the Handbook concerning e.g. the item and aggregate calculations? |
NO |
|
Are special estimation/calculation methods used for main crops from arable land? |
NO |
|
Are special estimation/calculation methods used for vegetables or strawberries? |
NO |
|
Are special estimation/calculation methods used for permanent crops for human consumption? |
NO |
|
Are special estimation/calculation methods used for main land use? |
NO |
|
Do national crop item definitions differ from the definitions in the Handbook (D-flagged data)? |
NO |
|
In case yes, how do they differ? ( list all items and explanations) |

Population
Which measures were taken in order to make sure that the requirement stipulated in Art. 3.2 are met? (Statistics shall be representative of at least 95 % of the areas of each table in the Regulation). |
The Survey on land cover and land use of the territory of Bulgaria (Table 4) covers the entire territory of the country without applying a threshold. For crop Tabl.1, 2, 3 there is a population, including all units, growing the relevant crops for which data are available from the census of agricultural holdings and/or from administrative sources. While drawing the sample the units are chosen from the relevant population. In the selected samples representative farms of different sizes and specialization are chosen. |
Is the data collection based on holdings? |
YES |
If yes, how the holdings were identified? |
Unique statistical farm identifier |
If not, on which unit the data collection is based on? |
The observed units are land cover points from surveys Early estimation-wheat, barley and land cover and land use of the territory of Bulgaria. |
When was last update of the holding register? (month/year) |
Bg has no full administrative register. |
Was a threshold applied? |
