The Role of Cultivation Methods and Lowlands Growing Environment on the Growth of Shallot (Allium ascalonicum L.) Varieties

Abstract

Abstract The success of the shallots’ growth and production is strongly affected by the cultivation method, the variety selection, and the growing environment (location-specific cultivation). This study aims to evaluate the shallot’s growth using true shallot seed to cultivation methods in a lowland growing environment. The research is conducted in Pasar 1 Tanjung Sari-Medan community land located at an altitude of 32 meters, during June to September 2021. This study applies a factorial randomized block design, the first factor is the shallots variety using TSS (Lokananta and Sanren F1). The second factor is the difference in plant cultivation methods (seed supplier recommendation, modification of seed supplier recommendation, multiple production recommendation, modification of multiple productions). The results show that in the lowlands, plant height, number of leaves, and total of leaf area of Lokananta are higher than Sanren F1. The use of cultivation methods seed supplier recommendation increased in plant height and total leaf area. The combination of Lokananta treatment and seed supplier recommendation method results in the best plant growth indicated by an increase in plant height and total leaf area.
