Abstract:
Background and Objective: Sulphur is very important to increase assimilate translocation to enlarge bulbs, forming essential amino acids. The presence of growth inhibitors is necessary to focus energy on the formation of shallot bulb. The aim of this research was to evaluate the role of sulphur and Paclobutrazol on the production and physiological characteristics of shallot from true shallot seed. Materials and Methods: The study was conducted in Medan, Sumatera Utara, from June-October, 2020. The experimental design used was a factorial randomized block design. The first factor was sulphur application (0, 75 and 150 kg ZA ha1) and the second factor was concentration of Paclobutrazol (0, 15 and 30 ppm) to observe the true shallot seeds variety. Results: The result of the research indicated that the highest of chlorophyll a, chlorophyll b, total chlorophyll, wet weight and dry weight of shallot bulbs were found in the application of sulphur 150 kg ZA ha1 and without application of Paclobutrazol. Conclusion: The highest of total chlorophyll, bulb dry weight wet weight of shallot bulbs, chlorophyll total, shallot bulb wet weight and shallot bulbs dry weight were found in the sulphur treatment 150 kg ZA. ha1 and without Paclobutrazol. The highest of chlorophyll total was found in Paclobutrazol 15-30 ppm application.
