Growth, Yield and Quality of Ginger from Produced through Early Senescence
Melati, Satriyas Ilyas, Endah Retno Palupi, Anas Dinurrohman Susila

As so far, ginger seed rhizome used for planting is derived from 9 months or more after planting. Erratic climate change led to a long dry season. During the day, temperatures tend to higher up to 40?C, causing impaired growth and development of the ginger rhizome. Many ginger plant yellowed and senescense on 7 months after planting (MAP), make farmers difficult to get ginger seed rhizome. Rhizomes derived from 7th and 8th MAP have never been used for seed. Ginger for consumption purpose typically harvested at 5 MAP. This study aims to determine the effect of seed rhizome age on growth, yield and quality of rhizome. The results showed the seed rhizomes aged 8 MAP produce the best growing (plant height, number of tillers, stem diameter, number of leaves). Rhizome quality at the 5th months showed water content and starch, fibers were not significantly different between the ages of the seed. Production of ginger showed the highest yield at 8 MAP. Rhizome of early senescence can be used as seeds and the best results obtained at 8 MAP.
