Abstract
Hardpan disruption had no effect on percolation in the following wet season, although it increased percolation by 56-70% in two of the four fields in the first 30 days after transplanting. Consequently, hardpan disruption gave gross benefits 2.7-9.8 times the costs of disruption, with a maize price of US$ 180Â tâ1, in those situations where it increased maize grain yield.
