Choice of maize hybrids for acid soils based on field experiments

Ten maize hybrids were grown on two soil types during 1998 and 1999. Maize yields on acid pseudogley (PS) were about 25% lower in comparison with neutral alluvial soil (AS). However, yield depressions among the hybrids on PS varied from 8% to 33%. OsSK554, OsSK425 and OsSK382 yielded on AS more than 30% lower (mean 9.10 t ha-1) than on AS (mean 13.42 t ha-1), while for OsSK332, OsSK444 and OsSK490exp these differences remained under 15% (means 10.57 and 11.89 t ha-1, respectively). Increase of corn yields without liming is possible with the choice of more tolerant hybrids.
