FORAGE BIOMASS YIELD PERFORMANCE OF RHODES GRASS (Chloris gayana) ACCESSIONS IN BENISHNGUL-GUMUZ ...

The experiment was carried out at the Assosa Agricultural Research Center's Kamashi and Assosa forage research stations to assess the forage yield performance of five chloris gayana accessions in low and mid-altitude agro-ecologies. Low- and mid-altitude agro-ecologies were represented by Kamashi and Assosa, respectively. The research was done in a three-replication randomised full block design. The tested agro-ecologies differed considerably (P 0.001) in plant height at forage harvesting, days to forage harvest, forage dry matter yield, and leaf to stem ratio. Kamashi provided the maximum plant height at forage harvesting and forage dry matter production, while Assosa had the highest leaf to stem ratio. Plant height, days to forage harvest, and leaf to stem ratio were all affected by genotype (P 0.001). The interplay of genotype and environment had a significant (P 0.05) effect on plant height. A combined study revealed that genotype had a significant (P 0.001) impact on the days to forage harvest. Days to forage harvest differed considerably (P 0.001) among the genotypes studied in both environments, and C. gayana cv., massaba, matured earlier than the other tested Chloris gyana accessions in both. Finally, agro-ecology influences the plant height, dry matter output, leaf to stem ratio, and days to maturity of C. gayana.
