Summary

Late planting of a 136-day variety of maize led to reduced yields only when planting was later than about four weeks after the start of the main rains. The reductions were caused by drought at the end of the season and by high rainfall in the first 35 days after planting. Drought beginning 80–100 days after planting (DAP) reduced weight per seed but drought beginning earlier than 80 DAP reduced seed number per cob and increased the number of barren plants. Late showers alleviated the reduction in weight per seed but not the other symptoms of drought. High rainfall after planting was associated with reduced plant size at flowering and reduced seed number per cob at harvest.
