SOUTH African maize futures contracts traded mixed on Tuesday, mirroring diverse views in the market on the extent and impact of recent rainfall in key growing areas. “The rains are very late. Although there is still time to plant, farmers are slowly getting concerned,” Giel van Zyl, general manager of the National Maize Producers Organisation said. December white maize futures ended unchanged at 810 rand, but March white dipped 80 cents to R821,20. Later months rose. December yellow lost R7 to R858. The wheat crop expects a wheat crop of 1,509-million tons compared to last season’s 1,531-million.
