Pemanfaatan Limbah Serbuk Gergaji Dan Arang Sekam Padi Sebagai Media Sapih Untuk Cempaka Kuning (Michelia Champaca)

Abstract

To support the cultivation of yellow cempaka (Michelia champaca) intensively, high quality seedlings was needed. One of the factors that affect the growth and quality of seedling was growth media. The objectives of the research were to (1) determine the effect of saw dust and rice husk as growth media than the top soil for yellow cempaka seedlings; (2) obtained the best composite media between top soil with saw dust and rice husk as media for growth media for yellow cempaka seedlings. The research was conducted in greenhouse, started from January to April 2013. The experiment used Completely Randomized Design (CRD) with 6 treatments and 3 replicates, every experiment unit consisted of 6 yellow cempaka seedlings so the total number amounted to 108 seedlings. The treatment were number of medias (1) top soil; (2) saw dust; (3) rice husk; (4) top soil + saw dust 1:1; (5) top soil + rice husk 1:1; (6) top soil + saw dust + rice husk 1:1:1. Observed variables include high growth, diameter, number of leaves, root length, top root ratio, total dry weight and seedling quality index. The results showed that growth media of rice husk gave a good growth of yellow cempaka same as media top soil. Composite growth media that had a better growth of yellow cempaka seedling was composite growth media top soil + rice husk 1:1.

The Study of Growth and Its Polyembryonic Properties of Porang Seeds (Amorphophallus muelleri Blume) from Various Fruit Colors in Different Planting Media

“…The loose of media was allegedly due to the presence of husk charcoal. Characteristics of husk charcoal are to reduce the density of the media therefore the plant roots easily penetrate the media [11]. In addition to the roots, loose media will also make the plumula penetrate the surface of the growing media smoothly.…”

PENGARUH KOMPOSISI MEDIA TANAM TERHADAP PERTUMBUHAN DAN HASIL TANAMAN BUNGA GLADIOL (Gladiolus hybridus L.)

“…Tanah sebagai media tanam yang dicampurkan dengan arang sekam dapat memperbaiki poripori media tanam sehingga baik untuk respirasi akar, dapat mempertahankan kelembaban media karena arang sekam dapat mengikat air, dimana air tersebut dilepaskan ke pori mikro untuk diserap oleh tanaman dan mendorong pertumbuhan mikroorganisme yang berguna bagi tanah dan tanaman (Kusmarwiyah dan Sri, 2011). Arang sekam memiliki pori yang lebih besar maka daya serap yang dihasilkan pun tinggi, hal ini membuat arang sekam mampu menyerap dan menyimpan unsur hara dengan baik (Agustin et al, 2014).…”
