ABSTRAK
Perbanyakan Mucuna bracteatasangat sulit dilakukan dan memerlukan
perlakuan khusus untuk berkecambah. Perlakuan perendaman dengan kalium
nitratpada biji mucuna bertujuan untuk meningkatkan kecepatan
berkecambahdandaya kecambah. Penelitian inidilakukan di Kebun Percobaan
Fakultas Pertanian UPN “Veteran” Yogyakarta, pada bulan Mei sampai Juni
2015 menggunakan Rancangan Acak Lengkap (RAL) 16 kombinasi
perlakuan, setiap perlakuan diulang sebanyak 3 kali. Faktor pertama adalah
lama perendaman terdiri atas 4 aras, yaitu: (W1) = Lama perendaman 6 jam,
(W2) = Lama perendaman 12 jam, (W3) = Lama perendaman 18 jam dan
(W4) = Lama perendaman 24 jam. Faktor kedua adalah konsentrasi KNO
3
terdiri atas empat aras, yaitu: (K0) = Konsentrasi 0 %, (K1) = Konsentrasi 2
%, (K2) = Konsentrasi 4 % dan (K3) = Konsentrasi 6 %. Hasil penelitian
menunjukkan bahwa parameter daya kecambah dan pertumbuhan bibit umur
2 mst terdapat interaksi serta berpengaruh nyata sedangkan konsentrasi KNO
3
2% (K1)yang direndam selama 12 jam (W2) memberikan hasil cukup baik
pada perkecambahan Mucuna bracteata.
Kata kunci : Mucuna bracteata, KNO

Bracteata mucuna generative propagation is very difficult and requires special
treatment to germinate. Soaking treatment with potassium nitrate in mucuna seed
aims to improve germination. This research was conducted at the experimental
field of the Faculty of Agriculture UPN "Veteran " Yogyakarta, in May to June
2015 , using a completely randomized design ( CRD ) 16 combinations of
treatments , each treatment was repeated 3 times . The first factor is the long
immersion consists of four levels , namely : ( W1 ) = Length of immersion 6
hours , ( W2 ) = Long soaking 12 hours , ( W3 ) = 18 hours and immersion Lama (
W4 ) = Length of immersion 24 hours . The second factor is the concentration of
KNO 3 consists of four levels , namely : ( K0 ) = concentration of 0 % , ( K1 ) =
concentration of 2 % , ( K2 ) = concentration of 4 % and ( K3 ) = concentration of
6 % . The results showed that there was an interaction between the soaking time
with KNO3 . Treatment with a solution of KNO3 soaking time give the best effect
on germination percentage , speed of germination , germination , seedling height ,
number of leaves and stem diameter .
Key word : Mucuna bracteata, KNO
