  An experiment was conducted to determine the component and summative yields of Columbus grass and Centurion species in Semi arid zone. The treatment combination were seed rate of 30 kg ha-1 of Sorghum almum, 10 kg ha-1 Centrosema pascuorum each representing 100% sole pasture and their mixtures in the ratios of 25% S. almum: 75% C. pascuorum, 50% S. almum: 50% C. pascuorum and 57% S. almum: 25% C. pascourum laid out in a complete randomized block design using plot size of 4x2 m. Pasture was sampled to monitor establishment and physiological development from 14 Days Post-Planting (DPP) and thereafter at 2 weeks interval up to full bloom stage. At full bloom stage forage was harvested to determine Dry Matter yield (DM). Results obtained showed stand counts of Sorghum almum statistically (p<0.05) increased from day 14 and attained a maximum by 56 days. From 42 DPP and subsequently, mixture with 25 or 50% C. pascourum had higher (p<0.05) stand counts relative to other treatments. Pasture height varied from 25.1-28.5 cm at 14 DPP. Thereafter, from 42 DPP, differences (p<0.05) manifested up to 84 DPP amongst the treatments evaluated. The treatment with 25% C. pascourum had taller (p<0.05) sward stand relative to other factors. Sward grown in mixture were comparable (p>0.05) in fresh leaf (75-83%). Dry matter yield was significantly different (p<0.05) in both component and cumulative yield. The mixture with 50% C. pascourum was statistically superior to all other treatments. Higher (p<0.05) total DM yield was obtained with treatment that had 50% S. almum plus 50% C. pascourum. Cost-benefit analysis of production showed higher output and net benefit from the mixed pasture sward of 50% Columbus grass and 50% Centurion. Based on the results of the present study, commercial pasture production would be more economical from mixed pasture sward of 50% Columbus grass and 50% Centurion in the zone.

  An experiment was conducted to determine the species of legume that is compatible with Columbus grass for ensilage and to establish the optimum proportion of legume inclusion for better silage preparation. Field grown Columbus grass (Sorghum almum Parodi) was sampled at soft dough stage and fortified with legumes forage from Centurion (Centrocema pascourum L.); Lablab bean (Lablab purpureum (L.) and Groundnut (Arachis hypogea L). The treatments were 100% Columbus grass; 80% Columbus grass plus 20% groundnut; 60% Columbus grass plus 40% groundnut; 80% Columbus grass plus 20% Lablab; 60% Columbus grass plus 40% Lablab; 80% Columbus grass plus 20% Centurion and 60% Columbus grass plus 40% Centurion. Each of the treatment combination was ensilage using in vitro silos, kept at room temperature of 26C for 21days incubation period. Thereafter, pH and proximate composition were examined. The results obtained showed the compounded silages were good and moderately acidic with pH varying from 5.33-5.77. Higher acidic value was obtained from silage prepared of 60% Columbus grass plus 40% groundnut. Dry matter as fed varied significantly (p<0.05) from 308.0-508.0 g kg 1 succulent silage. Significantly higher (p<0.05) dry matter as fed was observed from treatments that had 60% Columbus grass plus 40% Lablab. Significantly higher CP was obtained from the inclusion of 40% of lablab. Organic matter content (OM) of the silage vary significantly (p<0.5) from 45.7-69.1%. Ether Extract (EE) varied (p<0.05) from 6.6-19.4% with the higher values obtained from Columbus grass plus 40% lablab. The content of ash obtained showed significant variations (p<0.05) in the composed silages. Higher OM and CF content were obtained from treatments that had 100% Columbus grass.
