The area for white corn, which is used to make a staple food, is 0.8% smaller at 1.26 million hectares, while that for yellow, generally used for animal feed, is seen shrinking 3.7% to 1.01 million hectares.
The sunflower area is 26% smaller at 444 000 hectares, the smallest in nine years, while the groundnut area, which is 66% down at 19 200 hectares, is the smallest on record.
The decline is due to less favourable rainfall and warm temperatures experienced in the peak planting window, Ndou said.
The committee reduced its estimate for the nation’s wheat crop by 1.7% to 1.8 million tons compared with its prior prediction.
South Africa produced 1.54 million tons of wheat in the previous season.
