PENGARUH KONSENTRASI GIBERELIN (GA3) DAN DOSIS CaCO3

ABSTRAK
Perkecambahan benih padi dengan viabilitas rendah dapat ditingkatkan
dengan perlakuan perendaman giberelin. Kalsium pada CaCO3 bermanfaat
terhadap pertumbuhan vegetatif dan hasil tanaman. Tujuan penelitian yaitu (1)
untuk mengetahui pengaruh konsentrasi giberelin terhadap perkecambahan dan
(2) untuk mengetahui interaksi antara konsentrasi giberelin dan dosis CaCO3
terhadap pertumbuhan vegetatif dan hasil. Penelitian menggunakan RAL dengan 2
percobaan. Percobaan I: pengaruh konsentrasi giberelin terhadap perkecambahan
benih (0, 150, 200, 250 ppm) dulang 5 kali. Percobaan II: perlakuan konsentrasi
giberelin sebagai faktor pertama dan dosis CaCO3 sebagai faktor kedua (0, 6, 12
g/polybag) dengan 3 kali ulangan terhadap pertumbuhan vegetatif dan hasil
tanaman padi. Data dianalisis menggunakan ANOVA dilanjut dengan DMRT 5%.
Hasil penelitian percobaan I konsentrasi giberelin tidak berpengaruh terhadap
perkecambahan. Percobaan II terdapat interaksi antara konsentrasi giberelin dan
dosis CaCO3 terhadap persentase gabah isi per malai, persentase gabah hampa per
malai, bobot GKG per malai, dan bobot 100 butir. Kombinasi perlakuan terbaik
pada konsentrasi 200 GA3 ppm & CaCO3 12 gr/polybag (G3K3). Perlakuan
konsentrasi giberelin tidak berpengaruh nyata pada variabel tinggi tanaman,
jumlah anakan, dan panjang malai demikian pula pada perlakuan dosis CaCO3.

THE EFFECT OF GIBBERELLIN CONCENTRATION (GA3) AND DOSAGE
OF CaCO3 ON STORED SEEDS ON GERMINATION, VEGETATIVE
GROWTH, AND RICE PRODUCTION
(Oryza sativa L.)

ABSTRACT
Germination of rice seeds with low viability can be increased by gibberellin
immersion treatment. Calcium in CaCO3 is beneficial for vegetative growth and
plant yields. The research objectives were (1) to determine the effect of
gibberellin concentrations on germination and (2) to determine the interaction
between gibberellin concentrations and CaCO3 doses on vegetative growth and
yield. Research using RAL with 2 experiments. Experiment I: effect of gibberellin
concentration on seed germination (0, 150, 200, 250 ppm) repeated 5 times.
Experiment II: treatment of gibberellin concentration as the first factor and dose
of CaCO3 as the second factor (0, 6, 12 g/polybag) with 3 replications on the
vegetative growth and yield of rice plants. Data were analyzed using ANOVA
followed by 5% DMRT. The results of the first trial of gibberellin concentration
did not affect germination. In Experiment II, there was an interaction between
gibberellin concentrations and CaCO3 doses on the percentage of filled grain per
panicle, the percentage of empty grain per panicle, the weight of GKG per
panicle, and the weight of 100 grains. The best treatment combination was at a
concentration of 200 GA3 ppm & CaCO3 12 gr/polybag (G3K3) for the
percentage of filled grain per panicle, the weight of the GKG per panicle, and the
weight of 100 grains. Treatment of gibberellin concentrations did not significantly
affect plant height, number of tillers, and panicle length, as well as treatment of
CaCO3 doses.
