Abstract
Fodder sorghums {Sorghum bicolor var. Abu-sabeen and Sorghum bicolor x Sorghum sudanensis (Piper) Stamf. var. Pioneer} were sown to compare quality and quantity of different cuts and growth stages. The results showed that Pioneer yielded more than Abu-sabeen. The yield was higher at the second cut for Pioneer, while it decreased significantly for Abu-sabeen from the first to the third cuts. The percent reduction in yield between the first and third cuts was 39% and 49% for Pioneer and Abu-sabeen, respectively. The first cut of the two forages showed the same quality value while Pioneer was superior for the second cut. Forage yield and crude fibre increased significantly for the two crops with age, while crude protein percent decreased. Comparison between the percent increase of forage with the percent decrease in quality indicated that the best stage of cutting was when the crops were at 25% bloom.
