ABSTRAK
Tanaman padi merupakan tanaman yang memiliki sifat dormansi fisiologis dan
memiliki fase after ripening. Untuk mematahkan dormansi pada benih padi,
kemampuan menghasilkan serta meningkatkan produktivitasnya dapat dilakukan
dengan memberikan KNO3 dan air kelapa. Tujuan penelitian ini adalah menentukan
konsentrasi KNO3 dan air kelapa yang tepat terhadap pematahan dormansi dan
pertumbuhan benih padi. Penelitian ini menggunakan Rancangan Acak Lengkap
(RAL) faktorial dengan 2 faktor, faktor I : Konsentrasi KNO3 (M) yaitu M0 : 0%,
M1 : 1%, M2 : 3%, M3 : 5%. Faktor II : Konsentrasi Air Kelapa (K) yaitu K0 : 0%,
K1 : 25%, K2 : 50%, K3 : 75%. Terdapat 16 kombinasi perlakuan dan diulang 3
kali. Parameter pengamatannya yaitu daya kecambah, laju perkecambahan, bobot
kering kecambah, indeks vigor, potensi tumbuh maksimum, jumlah daun, tinggi
tanaman, jumlah anakan, dan bobot kering tanaman. Data pengamatan dianalisis
secara statistik menggunakan uji ANOVA taraf 5% dan apabila terdapat beda nyata
antar perlakuan dilanjutkan dengan uji jarak berganda DMRT pada taraf 5%. Hasil
penelitian menunjukkan terdapat interaksi antara perlakuan KNO3 3% dan air
kelapa 50% terhadap daya berkecambah, laju perkecambahan, indeks vigor dan
jumlah daun minggu ke 4. Perlakuan terbaik pada kombinasi perlakuan M2K2
untuk parameter daya berkecambah, indeks vigor dan jumlah daun minggu ke 4.
KNO3 3% dan Air Kelapa 50% meningkatkan potensi tumbuh maksimum, jumlah
daun minggu ke 6 dan tinggi tanaman minggu ke 2,4 dan 6.

ABSTRACT
Rice is a plant that has physiological dormancy and after-ripening phase. For
breaking dormancy, abillity to produce, and increased productivity seeds of rice can
be done by several alternatives, including by providing KNO3 and coconut water.
The aim of this research is determine the appropriate concentration of KNO3 and
coconut water on breaking dormancy and growth of rice seeds. This study used a
factorial Completely Randomized Design (CRD) with 2 factors, factor I: KNO3
concentration (M), namely M0: 0%, M1: 1%, M2: 3%, M3: 5%. Factor II: Coconut
Water Concentration (K), namely K0: 0%, K1: 25%, K2: 50%, K3: 75%. There
were 16 treatment combinations and repeated 3 times. Variabel observed is
germination, germination rate, dry weight of sprouts, vigor index, the maximum
growth potential, number of leaves, plant height, number of tillers, an dry weight
of plants. Data is analyzed statistically using the ANOVA test at 5% level and if
there was a significant difference between treatments, it was continued with DMRT
at 5% level. The result showed that there was an interaction between the treatment
of 3% KNO3 and 50% coconut water on germination, germination rate, vigor index
and number at week 4. The best treatment was in the M2K2 treatment combination
for the parameters of germination, vigor index and number of leaves at week 4.
KNO3 3% and coconut water 50% increased the maximum growth potential,
number of leaves at week 6 and plant height at week 2, 4 and 6.
