dc.description.abstract | Shallot is one leading horticultural commodities and has good
prospects as a seasoning and medicinal properties. In increasing of local samosir
shallot production, growth regulators and micronutrients are needed. Gibberellin
(GA₃), is a plant growth-stimulating hormone that when applied as an exogenous
hormone can trigger the appearance of flowers and flowering simultaneously. The
application of boron on shallots could increase the quality of seed and flowering
number. The aim of the study was to evaluate the production and quality of the
Samosir local True Shallot Seed (Allium Ascalonicum L.) through Gibberellins and
Boron treatment in the highlands. The research was conducted at Humbang
Hasundutan, North Sumatera Province, Indonesia from August to December 2022.
Factorial randomized block design was used with two-factor and 3 replication. The
first factor was the application of Gibberelin (0; 100; 200 and 300 ppm), the second
factor is Boron (0, 3 and 6 kg/ha). The results showed that the administration of
Gibberellin treatment increased several observed variables of plant growth,
production, generative, namely number of leaves and number of tillers, chlorophyll
and sulfate content, wet and dry weight of shoots, flowering number of local
Samosir shallots. Concentration of Gibberellin 100 ppm can increase and provide a
significant difference in the growth of the local Samosir shallots and the addition
of a higher dose has no significant effect on the observed variables of the plants.
Boron at a dose of 6 kg/ha can increase growth, crop production such as plant
length, number of leaves and tillers, chlorophyll content, wet and dry weight of
shoots, flowering number of local Samosir shallots. The interaction of Gibberellins
and Boron can increase the wet and dry weight of shoots, and number of flowering
of local Samosir shallots. | en_US |
