Differences in Cultivation Methods and Their Effects on Production and Physiological Characteristics of Shallots in the Highlands

Abstract

Background and Objective: The productivity and quality of shallots from true shallot seeds are highly dependent on site-specific cultivation methods and the selection of appropriate varieties. The objective of the research was to evaluate the cultivation method and selection of the best varieties in the highlands to increase the productivity and physiological characteristics of shallots from TSS. Materials and Methods: The study took place on community land in Sempajaya, Berastagi, Tanah Karo Regency in June-September, 2022, using a factorial randomized block design. The first factor is the variety of shallots from tubers (Lokananta and Sanren F1) and the second factor is the difference in the method of cultivating shallots from TSS in the highlands. Results: Growth, production and chlorophyll content of the Lokananta variety were higher than Sanren F1. The shallot cultivation method recommended by seed suppliers is the best. The interaction between the Lokananta variety and the cultivation method of the seed supplier increased the growth and production of shallots from TSS. Conclusion: The dry weight of tubers increased by 9.84% on the use of the seed supply method when compared to the recommendation for double production. The use of the Lokananta variety increased tuber weight per plot (1×1 m) by 39.28% compared to Sanren F1.
