South Africa boosted its estimate for this year’s corn harvest by 0.5 percent, after an increase in yields in the Free State province.

Farmers will probably reap 10.56 million tons in the 2018-19 season, Marda Scheepers, a statistician for the Pretoria-based Crop Estimates Committee, said by phone Tuesday. The committee forecast a crop of 10.51 million tons last month, in its first estimate for the season.

South Africa, historically the continent’s biggest corn producer, harvested 12.51 million tons of corn last year, a decrease from a record haul of 16.82 million tons in 2016-17
