The second estimate for the Czech Republic's total 2009 grain harvest is 6.717 million tonnes, down 10.4 percent from the 2008 harvest of 7.497 million tonnes, the Czech Statistics Office, or CSU, said Tuesday.

The estimate is based on data collected from local farmers July 15. The July harvest projection is higher than the 6.622 million tonnes of the first estimate based on data collected June 20.

The harvests of most crops are expected to be down on 2008 due to lower yields and a slightly smaller overall planted area, the CSU said.

Despite the year-on-year harvest volume decline, the actual amounts will be average in long-term comparisons, the CSU added.

The estimated wheat grain crop yield is expected to total 5.02 tonnes a hectare this year, down from 5.77 tonnes a hectare in 2008.

Rye yields are expected to be 4.15 tonnes a hectare, down from last year's 4.83 tonnes a hectare.

The estimated rapeseed crop yield is expected to total 2.82 tonnes a hectare in 2009, lower than the final rapeseed crop yield of 2.94 tonnes a hectare in 2008.
