The Growth and Yield Responses of Shallot (Allium Ascalonicum L.) to Plant Spacing and Tuber Cutting by NFT Hydroponic

Abstract

Shallot (Allium ascalonicum L.) is a kind of horticultural commodity, which has good development potential in Indonesia. In order to overcome the uncertainty of climatic conditions and demand that continues to increase as the population of Indonesia increases, it is necessary to develop shallot cultivation techniques using the NFT hydroponic system. This study aimed to determine the effect of the interaction between plant spacing and tuber cutting on the growth and yield of shallots. The study was conducted in February-April 2021 at Hidroponikpedia, Pandowoharjo, Kab. Sleman, Special Region of Yogyakarta 55512. 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). Record data on growth and yield parameters, and perform analysis of variance (ANOVA) at the 5% level of significance. The results showed that there was no interaction between plant spacing and tuber cutting on the growth and yield of shallot. The tuber cutting treatment has obvious growth and yield, but the difference in plant spacing between the kinds of plant spacing is not significant.
