Dry Season Biomass Production of Leucaena lecocephala cv Tarramba at 4 months regrowth and from Several Longer Regrowth Plants on Sandy Vertisol Soil at Naibonat, West Timor-Indonesia

The following paper is a continuation of the previous experiment on the wet season forage production of Leucaena leucocephala cv Tarramba already published. In the recent continuing experiment, measurements were conducted on two 4 months cutting intervals during the 2021 dry season and some additional data were also included from the measurements of biomass production of 6 months, 12 months, and 24 months plant stands to provide more complete information on edible forage and wood production. Data recorded included: leaf production, stem skin (bark) production, stem production, stem diameter, and plant height. With the current model (6,264 plants), the 1 year (2021) edible biomass can support 5 bulls at the first 2 months interval (January to February), and 2 bulls at the second two months interval (March to April), during the wet season. While at the first 4 months interval in 2021 during the dry season (May to August) the model can support 1.8 bulls, and about 2.5 bulls during the second 4 months cutting interval (September to December 2021). If the density is applied to 1 ha with 20.000 plants it may support 6-16 fattening bulls according to the season at biomass production.
