Abstract

 

The study was conducted
at Hawassa Agricultural Research Center in Ethiopia to determine the optimum
seed rate proportion of mixtures of Chloris gayana (CG) and Medicago sativa
(MS) for obtaining higher dry matter yield (DM) from the mixtures. CG and MS
were planted as pure stand and in mixtures using 75%(CG) + 25%(MS), 50%(CG) +
50%(MS), 25%(CG) + 75%(MS), 0%(CG) + 100%(MS) and 100%(CG) + 0%(MS),100%(CG) +
25% (MS) and 100%(CG) +50%(MS) seed rate proportion in a randomized complete
block design with three replications. There were significant (P < 0.05)
differences in the crud protein and lignin of the grass components among the
grass/legume combinations due to seed rate proportions. Not significant (P >
0.05) effects were observed on the DM, the relative yield (RY) and the relative
total yield (RTY). However; the 50: 50% mixture gave higher DM yield and had
the highest RTY than other mixtures. From this result, it is concluded that
50: 50% mixture was found to be the optimum seed rate proportion to develop a
balanced grass-legume mixture. In addition, further studies need to be
undertaken under varying environments and harvesting strategies.
