Summary

The effects of sowing pattern and seed rate on the green-chop yield of forage sorghum-sudangrass hybrid (cv. Pioneer 988) and forage sorghum (cv. Abu Sabeen) were investigated. In general, more green-chop yield was obtained from seed of both cultivars drilled in regular rows, double rows and triple rows than when traditionally sown as broadcast seed. Yields were greater when plants were sown at 70 kg seed ha−1 than when traditionally sown at 35 kg seed ha−1. These yield advantages were sustained through three successional harvests. Pioneer 988 generally yielded more than Abu Sabeen, especially when sown in January. Both cultivars gave minimum yield when sown in April, July or October.
