Three cultivars of Cenchrus purpureus (cvs. Cipelang, Biograss, and Mott) grown on Sandy Vertisol Soil at Naibonat, West Timor-Indonesia were evaluated for their biomass production (leaf, leaf sheath, and stem) and some agronomic characters (plant height, stem diameter, leaf length, and leaf width). Plants were planted in rows of 1 m x 1 m at 6 m length in a Block Randomized arrangement and replicated four times. Plants were established in October 2021 by watering using sprinklers during the dry season (just to keep the soil moist enough to still encourage growth) and under rainfall during the wet season (rainfall data presented). Harvests were conducted in 2022 (wet and dry season). No chemical fertilizer was applied, however, 3 kgs of manure were applied in each planting hole, and the soil surface of the plot was evenly covered by dry leaves of bamboo collected from nearby the plot. Data collected were then subjected to Analysis of Variance using the SPSS program and means were compared using the List Significant Difference (LSD) test. Biomass production was significantly different between cv Mott compared with Cipelang and Biograss, however, there was no significant difference recorded between Cipelang and Biograss at each harvest as well as for one-year total biomass production.
