PERTUMBUHAN BIBIT KALIANDRA PADA BEBERAPA KOMPOSISI MEDIA SEMAI CETAK DI PERSEMAIAN DAN LAPANGAN

Abstract

Planting of k aliandra (Caliandra calothyrsus Meissn.) is generally carried out by preparing the seedling using polybagwith top soil media. Large quantities of polybag may pollute the forest soil because polyethylene is difficult to be degraded. The research aimed to test ten compositions of block seedling media as a growth media for kaliandra seedlings in nursery and field. The research used randomized completely design for testing the effect o f block seedling media compositions on (1) the strength of block ed seedling media; (2) growth of k aliandra seedlings in the nursery and field test. The result showed that the media composition KM-3 (mixed media of compost 40%, rice hull charcoal 20%, soil 20%, lime 10%, tapioca 10%, rhizobium 3 g), KM-7 (compost 30%, rice hull charcoal 20%, soil 30%, lime 10%, tapioca 10%, rhizobium 3 g) and KM-8 (compost 30%, rice hull charcoal 20%, soil 30%, lime 10%, tapioca 10%, mycorrhizae 3 g) had intactness media level more than 90% after 2 months testing in nursery. Composition of KM-3 was the best growth media for kaliandra seedlings in nursery and field testing.
