Incorporated Sorghum Residues Reduce Emergence and Seedling Growth of Some Crops

Abstract Allelochemicals from sorghum [Sorghum bicolor (L.) Moench] residues may inhibit the emergence and growth of other crops. We examined the effects of residues from two sorghum landraces, IS9456, a high sorgoleone producer, and IS22320, a zero sorgoleone producer. Residues were applied at 7.2...

We examined the effects of residues from two sorghum landraces, IS9456, a high sorgoleone producer, and IS22320, a zero sorgoleone producer. Residues were applied at 7.2 g, 14.4 g and 21.6 g kg−1 of soil. Emergence and the growth of maize (Zea mays L.), wheat (Triticum aestivum L.) and soybean [Glycine max (L.) Merr.] were tested in three glasshouse pot experiments at the University of Zimbabwe in 2017. The 2×3 factorial experiments were laid as a randomized complete block design with six replications.
