MORPHOLOGY AND BIOMASS PRODUCTION OF Chloris gayana cv. Callide,
AND Megathyrsus maximus cv. Gatton IN THE FIRST YEAR OF PLANTING IN YOGYAKARTA
ABSTRACT
This study aimed to determine the morphological character and biomass production of Chloris gayana
cv. Callide and Megathyrsus maximus cv. Gatton was introduced in Yogyakarta in the first year of planting.
The plants were grown using seeds in plots measuring 2x2 m by spreading the seeds. Each species was
planted with 5 replications. The data observed included morphological characters, biomass production, dry
matter, and organic matter content. The data obtained were analyzed by descriptive and by t-test method.
The introduced grass was a perennial plant that showed good growth. Plant morphology was normal according
to the characters of these two plants. Chloris gayana cv. Callide had a dry matter production of 25.21 ton/ha/year in the first year (19.70% DM and 88.20% OM). Megathyrsus maximus cv. Gatton has a dry matter production of 32.44 ton/ha/year in the second regrowth (19.85% DM and 88.18% OM). Based on the research, it was concluded that Megathyrsus maximus cv. Gatton has higher biomass production than Chloris gayana cv. Callide.
