Allelopathic Effect of (Sorghum bicolor L.) on Radish (Raphanus sativus L.) Growth Characters

Sahar Y. Babiker, Elnasri M. Mutwali


A pot experiment was carried out to study the effect of sorghum residue on germination and some growth characters of radish. The experiment comprised of four treatments where the soil was incorporated with sorghum residue powder at 2, 2.5, 3 and 3.5%( w/w) for treatments T2, T3, T4 and T5, respectively, the control was free of sorghum residue. Results indicated that an increase was observed at low concentration of sorghum residue in germination, growth characters, but a decrease was detected in chlorophyll content and some elements (Na,Ca, K, P, ) content in radish incorporated with sorghum residue.
