Rawia A. Mohammed | Elnasri M. Mutwali | Elsir A. Salih

Abstract: A pot experiment was carried out in the autumn season of year 2015 to investigate the effects of seed size and compare it with the small seed size on the germination and some growth parameters of forage sorghum (cv. Abu Sabin) and harvest stage on yield components. The experiment was laid in a split plot design with seed size as main plot and the harvest stage as sub plot with three replicates. The results indicated that the seed size had no significant effect on germination and number of leaves, shoot dry weight in late bloom stage and root fresh weight in boot stage. However a significant effect was observed in plant weight, tiller density also there was significant effect on crude protein, crude fiber and sucrose percentage. The interaction between seed size and harvest stage didnt show any significant effects on each measured traits. The significant growth observed in larger size seed showed that larger size seed are good seed size for sorghum planting.
