Abstract
Shallot (Allium ascalonicum L.) is a horticultural commodity that has good potential to be developed in Indonesia. To overcome uncertain climatic conditions and demand that continues to increase along with the increase in population in Indonesia, it is necessary to develop technology in shallot cultivation that using NFT hydroponic system. This research was carried out with the aim to determine the interaction between plant spacing and tuber cutting on the growth and yield of shallot. The study used a two-factor split-plot design replicated 3 times. The main plot used plant spacing consisting of 3 levels (10x10 cm, 10x15 cm, and 10x20 cm) and the subplot used the tuber cutting consisting of 3 levels (without cutting, cutting 1/3 parts, and cutting 1/4 parts). Data on growth and yield parameters were recorded and subjected to analysis of variance (ANOVA) at a 5% level. The results showed that there were no interactions between plant spacing and tuber cutting of the shallot^s growth and yield. The treatment of tuber cutting produced tangible growth and yield, but there were no significant differences between the kinds of plant spacing.
