Pertumbuhan dan Hasil Tanaman Bawang Merah (Allium Ascalonicum L.) pada Aplikasi Pupuk Sp-36 dan Pupuk Organik Cair dari Ikan Red Devil Amphilophus Labiatus)

Abstract

Shallot (Allium ascalonicum L.) is a horticultural commodity with high economic value and is needed by the community as a food ingredient. Shallot also contributes to national inflation. Shallot is a commodity with great potential for development in North Sumatra, especially in the Toba region. One effort to increase the growth and production of Shallot plants can be done by applying SP-36 and Red Devil Liquid Organic Fish Fertilizer. This study aims to determine the best SP-36 and Red Devil Liquid Organic Fish Fertilizer for Shallot growth and production. The research was conducted from September to December 2023 in Lumban Silintong Village, Balige District, Toba Regency, North Sumatra, at an altitude of ± 945 m above sea level. The design used was a factorial randomized block design with three replications. The treatments studied were the first factor, SP-36 dosage, with four treatment levels (0 (control), 112.5 kg/ha, 225 kg/ha, 337.5 kg/ha) and the second factor, Red Devil liquid fish organic fertilizer dosage (0 (control), 3 g/plot, 5 g/plot). The results showed that the application of SP-36 had a significant effect on the observed variable, namely the fresh weight of plants per plot. The application of Red Devil fish liquid organic fertilizer significantly increased plant height, fresh weight of plants per plot, fresh weight of plants per sample, number of tubers per plot, and tuber diameter.
