03. Statistical presentationTop
03.1. Data description

Annual crop statistics provide statistics on the area under main arable crops, vegetables and permanent crops and production and yield levels.  The statistics are collected from  a wide variety of sources: surveys, administrative sources, experts and other data providers. The data collection covers early estimates (before the harvest) and the final data. Data are collected  at national and regional level  (NUTS2).

03.2. Classification system

Hierarchical crop classification system

03.3. Coverage - sector

The field of statistics on crop production includes the cultivation of annual crops, perennial plantations and production of crops and greenhouse in greenhouses (NACE A01.1-01.3).

03.4. Statistical concepts and definitions

See: Annual crop statistics Handbook

Since 2014, the Republic of Serbia has officially carried out statistical surveys on crop production in accordance with the  Regulation of European Union (EC) No 543/2009 and Eurostat Annual crop statistics Handbook.

03.5. Statistical unit

Utilised agricultural area cultivated by an agricultural holding.

03.6. Statistical population

All agricultural holdings growing crops.

03.7. Reference area

The entire territory of the country.

Note: Since 1999, the Republic Statistical Office does not have data for the Autonomous Province of Kosovo and Metohija, so they are not included in the coverage of data for the Republic of Serbia (total).

If the results were compared with other sources, please describe the results

Comparison were done with Register of agricultural holdings by MoA and there were expected differences. 

The difference occurs because of a different number of farms covered by the statistical survey and the number of farms covered by this administrative source.

The area of the most important crops that farm are reported in this subsides register are less for about 30% in accordance to statistical survey. For the same percentage is the smaller number of farms in this registry than in a statistical survey or AC2012.

The comparison was made also with the estimates of Agricultural extension services and there were no significant differences.  

The comparison were made with the estimates of Agricultural extension services and there were no significant differences.

Comparison were done withestimates of Agricultural extension services:

The data on harvested area and yield for cereals obtained in this sample survey on crop production were almost the same as the estimates of Agricultural extension services (especially for wheat and maize) as well as for industrial crops.

Comparison were done with estimates of Agricultural extension services:

The data on sown area for cereals obtained in this sample survey  were almost the same as the estimates of Agricultural extension services.

Comparison were done with estimates of Agricultural extension services:

The data on horticultural production obtained in this sample survey  were almost the same as the estimates of Agricultural extension services.

Additional comments

Sample survey on expected yield of late crops, fruit and grapes and realized production of early crops and fruits, September 2019 includs only about 2,800 of agricultural holdings in the sample. This survey is used to estimate the yield and production of major crops. The reason of increased the coefficient of variation for the group of dry pulses and protein crops is very low persentage of respondent units for this crop group (only 5%). The same reason is for increased the coefficient of variation of nut trees in sample survey of crop production, where the respondent units are only 2% for nut trees. 

           

 

13.3. Non-sampling error

Non sampling errors include: people who refused to answer the questionnaires, size of questionnaires (both surveys: Sample survey on sown areas at the end of spring sowing season, May/Jun 2019  and sample survey on crop production , November 2019 includes for about 100 indicators), questions interpretation by CATI interviewers  and data entry errors by CATI and regional offices interviewers.

Additional comments    

Serbia has carried out the Orchard survey in 2017, for the first time. The survey collected data on areas, planting density and age for apples, pears, apricots and peaches, by varieties, regardless of whether they are dessert or varieties for industrial processing. Also, data on areas for fruit species in total (not by varieties) were collected, for: plums, cherries, cherries, raspberries, quinces, walnuts, hazelnuts, almonds, blackberries and blueberries.

Due to the low differences beatween data collected before and after Orchard survey, data for years 2013-2016 were recalculated and new time series were published.

If there were considerable differences, which factors explain them?

 

 

Register of agricultural holdings on behalf of Ministry of Agriculture, Forestry and Water Managment (MoA) is register for subsidies applying. The result of differences between Register of MoA and regular annual crop statistics in 2019 are results of different total number of agricultural holdings as well as different number of agricultural holdings specialized for crop production. Register of MoA includes approximately 350 thousand of family agricultural holdings what is a half of the total number of family agricutural holdings in Statistical Farm Register (621.445).   

Also, the Ministry of Agriculture doesn’t perform subsidies for all grown crops, so the crop registration by holdings is restricted.

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).

In order to provide data in accordance with the requirements of Regulation, SORS didn’t make cut off while creating a sample frame for the Sample survey on sown areas at the end of spring sowing season, May/Jun 2019. Also, there was no cut off for a sample frame  for Sample survey on expected yield of late crops, fruit and grapes and realized production of early crops and fruits, (September 2019).

Sample for survey on crop production, November 2019 is created as a subsample of the agricultural holdings selected for the Survey on sown areas at the end of spring sowing season, May/Jun 2019 and all sample selection criteria are valid as for this survey.

Within the Sample survey on crop production, it was created and a separate samples for survey on areas sown in autumn sowing (for 6 winter crops) and separate sample for survey on horticultural production. Sampling frame was created from the SFR base. There  were allocated only those family farms that had Cereals for the production of grain or horticultural production In this way, statistics is representative of over 97% for total area under cultivation of crops from arable land.

Memorandum of anderstending between Ministry of Agriculture and Environmental protection (MoA) and Statistical Office of Republic of Serbia (SORS)

         
Use purpose of the estimates?

Expert estimates are made in order to monitor the seasonal agricultural work, area planting and condition of major agricultural crops, permanent crops and yield forecast by Ministry of Agriculture and Environmental protection.

         
What kind of expertise the experts have?

They are agricultural engineers, employed in agricultural advisory services at the Ministry of Agriculture.

         
What kind of estimation methods were used?

The methodology defines regular reporting on planted and harvested areas of crops, fruit trees and grape vines , using estimates from agricultural advisory services, as the only reliable way to determine the yield forecasts every week.

For this purpose, SORS has created a web questionnaire for data entry by the Agriculture extension services as well as final reports from the same aplication. This ensures a unique collection of high quality data, necessary for the MoA to conduct agricultural policy, and information which will SORS forwarded to Eurostat.

         
Were there any differences in the definition of the variables between the experts' estimates and those described in the Regulation? NO

The data obtained on the basis of expert assessments (Agricultural Advisory and Expert Stations) are compared with statistical surveys and available administrative data sources, at the level of the region and the Republic of Serbia, and there were no significant discrepancies.          
What were the possible limitations, drawbacks of using the data from expert estimate(s)?            
Additional comments

In 2014, SORS has replaced the previously used method of providing EECP and establish a new system, which means engagement of agriculture extension services. For now, there are no plans to replace the expert’s estimates for EECP by other data sources.

In the process of harmonization of agricultural statistical system with the statistical systems of the European Union (EU), SORS has adopted the standards and definitions of the EU, which completely changed the methodology of Annual Crop Statistics. Previously, till 2014th, the methodology of Annual Crop statistics were based on experts estimates. Several problems characterized this way of data collecting, but the most important were tardiness of cadastral data used for estimation as well as the almost complete absence of quality checks of data on crop production statistics. Also, a report on the quality of the data was not possible.

Now, Annul Crop Statistics, is based on the principle of full harmonization with Regulation (EC) No 543/2009 as well as with the definitions and concepts presented in the Eurostat Handbook for Annual Crop Statistics. Data collection is conducted on the basis of several annual sample surveys, one three annul sample survey on horticultural production and five annual Orchard survey.

This is the third Quality report on Annual Crop Statistics, refers to 2019.
