Pengaruh Pemberian Giberelin Dan Pupuk Kalium Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.)
ABSTRACT
This research aims to find out the interaction effect of gibberellin and
potassium fertilizer doses, the effect potassium fertilizer doses at various
gibberellin concentrations, gibberellin concentrations at various potassium
fertilizer doses, the main effect of gibberellin and potassium fertilizer which is
better for growth and the production of shallot plant. The research was conducted
at the UPT of the Faculty of Agriculture, Riau University, Pekanbaru starting
from December 2018 to February 2019 was experimentally arranged in divided
plot design using randomized completely design. The main plot was the
gibberellin concentrations (0, 100, 200 and 300) ppm. The sub plot was the dose
of potassium fertilizer (100 and 200) kg of KCl ha-1. The parameter observed were
plant height, total of leaves, diameter of bulbs, total bulbs per clump, fresh weight
of bulbs per clump/plot, and dry weight of bulbs. Data results were analyzed
statistically with Anova and Duncan test continued level of 5%. There is
interaction effect of gibberellin and potassium fertilizer increased the fresh weight
of bulbs. The treatment 100 kg of KCl ha-1 and 200 ppm of gibberellin increased
the fresh weight and dry weight of bulbs. The treatment 200 kg of KCl ha-1 and
200 ppm of gibberellin which is better to increased the total of leaves and
diameter of bulbs. The treatment of gibberellin 200 ppm which is better to
increased the fresh weight and dry weight of bulbs. The treatment of 200 of KCl
ha-1 increased the plant height and total of leaves.
Key words : Gibberellin, potassium, shallot, growth and production
