Last year, the highest yield of agricultural crops was harvested in Dobele, Aizpute and Nereta counties
Among all counties, the highest cereal yield was recorded in Dobele county. Experimental statistics* of the Central Statistical Bureau (CSB) shows that in 2017 the average yield of cereals in Latvia constituted 38.3 ql/ha, while the indicator registered in Dobele county was almost two times higher – 64.9 ql/ha (relative margin of error** 1.6 %).
In several counties, very high yield of cereals was harvested – from 49 to 65 cnt/ha. Dobele, Rundāle, Bauska, Jelgava, Tērvete and Auce counties in Zemgale region, Baldone, Ķekava, Olaine, Sēja, Tukums and Jaunpils in Pierīga region, Durbe, Grobiņa, Saldus and Brocēni in Kurzeme region, as well as Beverīna county in Vidzeme region were the most productive.
Last year, the average yield of pulses (peas, beans, vetches, lupins) in Latvia constituted 29.7 ql/ha, while in several counties – Auce, Dobele, Tērvete, Jelgava, Rundāle, Bauska in Zemgale region, Pāvilosta, Durbe, and Aizpute in Kurzeme, Jaunpils and Sēja in Pierīga, Rūjiena in Vidzeme and Zilupe in Latgale region, even 38–48 ql/ha were harvested. The highest yield of pulses was harvested in Aizpute county where it constituted 48.1 ql/ha (relative margin of error** 1.1 %) and exceeded the national average yield 1.6 times.
The average yield of rape harvested in Latvia constituted 27.8 ql/ha. In Tērvete, Rundāle and Nereta counties of Zemgale region as well as Ikšķile county of Pierīga region, 36–44 ql/ha were harvested. The highest yield of rape was harvested in Nereta county – 44 ql/ha (relative margin of error 12.42 %).
The CSB produced experimental statistics on average yield of cereals, pulses and rape in counties over the period from 2015 to 2017 based on the results of annual crop survey. The sampling method and sample size were intended for national and regional levels, however ensures also production of the statistics at county level. The statistics produced characterises the development of crop production sector.
Also, the quality of the experimental statistics produced was evaluated – relative margin of error in each administrative territory was found. The experimental statistics is available in the CSB database section Crop Production/ Annual data.
* CSB publishes experimental statistics to get user feedback, evaluate analytical potential of the data and relevance thereof to the actual reality and data user needs. By publishing experimental statistics, the CSB provides data users with new sources of information that may be used for development of plans in counties and decision making.
** Interpretation of the margin of error – the sample error with a credibility of 95 % is not greater than the margin of error indicated. The margin of error is expresses as the percentage of the estimate. More about the margin of error.
