Harvest Forecast - operative report

Methodology

Estimates of harvest of agricultural crops are carried out by the Czech Statistical Office as at 20 June, 15 July, 15 August, 15 September and 15 October. A basic threshold for a holding to be involved in the survey is 1 ha of utilized agricultural area (UAA) or other additional criteria relating to planting of intensive crops, livestock and fish breeding. Statistical survey is selective, mathematical-statistical methods are used for data summarization.

Areas with cereals and legumes include only areas harvested for grain. Cereals which are harvested in the milk maturity or for rotary driers are included in “other annual fodder plants”. Ergotic rye is included only in the range of grain production expected, other area with ergotic rye is calculated under item of “medicinal crops”. Mixtures of cereals including mixture of oats with barley furthermore millet, pagan, sorghum harvested for grain are included in “other cereals”. Yield of maize for grain is reported yield of grain without corncob in standard moisture. Legumes for fodder, mixtures of legumes and mixtures of cereals with legumes are under item of “other legumes”. Estimated yield of grain includes fodder tailings and it is reported after cleaning and drying of grain. Rape is reported separately without turnip rape.

Yield includes estimated average harvest of cultivated crop in tonnes related to 1 ha of sowing area (estimated production divided by sowing area). Total harvest is counted from estimated yield per 1 ha and sowing area (surveyed under Census of sowing areas as at 31 May 2007). Estimated yield of grain includes fodder tailings and it is reported after cleaning and drying of grain in a standard moisture.

Harvest of industrial sugar beet is indicated in netto weight after cleaning. Yield of fodder beet is not reported. Rape is reported separately without turnip rape, yield is reported after cleaning and drying of seed.

Estimate of annual fodder crops is calculated from green stage even in case of a part of area was harvested for the hay. The acreage of green maize is not corrected additionally and yield is related to spring sowing areas similarly as in case of other agricultural crops. Yield of perennial fodder crops is summarized for all cuts together. Yield of perennial fodder crops is transferred into a dried fodder with the coefficient 4:1 and as a hay with the coefficient 3:1. Fodder from permanent grassland (permanent pastures and meadows) in the case it is harvested in green stage or pastured is recalculated for a hay with the coefficient 4:1.

Data are summarized for total republic and at the NUT-3 level (regions). Published results are calculated from non-rounded values.
