Abstract
The aim of this study was to obtain the weight of tillers and appropriate seeding time as a source of sago seeds by using the immersion technique on a raft to improve seed quality to support sago cultivation. The experiment used a factorial design arranged in a randomized block design with three replications. Factor A is sucker weight, consisting of <999 g, 1000-1999 g, 2000-2999 g and > 3000 g. Factor B is the length of immersion time, namely, 1 MAS, 2 MAS, 3 MAS and 4 MAS. The results showed that there was an interaction between sucker weight and the number of rachis initiated, the increase in rachis height and the number of leaves, but there was no interaction with the number of live seedlings. The highest number of real initiated rachis was obtained in the combination of sucker weights of 1000-1999 g at 16 MSS immersion time. The lowest rate of increase in height of rachis was obtained from sucker weight >3000 g at 2-3 MAS immersion time, while the rate of increase in the number of seedling leaves was more obtained at sucker weight treatment >3000 g and duration of immersion 2-3 MAS and sucker weight <999 g and duration of immersion 2-3 MAS but not significantly different with the treatment of sucker weight <999 g and duration of immersion 1-2 MAS and 3-4 MAS and sucker weight >3000 g and duration of immersion 1-2 MAS. If you want to propagate sago seedlings by immersion in a raft, it is more appropriate to use a sucker/sapling with medium weight, namely 1000-1999 g and 2000-2999 g, and the duration of immersion is 3 MAS.
