Applying Types Of Solid And Liquid Organic Fertilizer Dosages To Onion (Allium ascalonicum L.) Production

Abstract

One of the plant cultivation techniques to increase shallot production is fertilization. Fertilization is the application of fertilizer to increase the supply of nutrients needed by plants to improve the yield and quality of plant products. This research aims to determine and obtain a combination of the type of organic fertilizer and dosage of liquid organic fertilizer that has the best effect on the production of shallots (Allium ascalonicum L.). The research was conducted on farmers' land in Sukajadi Village, Talang Kelapa District, Banyuasin Regency, South Sumatra. The study was carried out from March to June 2023. This research used an experimental method with a split-plot design with 12 treatment combinations repeated 3 times. The treatment in question is the main plot: type of organic fertilizer consisting of chicken manure, buffalo dung fertilizer, and goat dung fertilizer, while sub-plots: dosage of liquid organic fertilizer consisting of control; 10 L/ha; 15 L/ha and 20 L/ha. The variables observed were the number of tubers per cluster (tuber), tuber weight per cluster (g), and tuber weight per plot (kg). The research results showed that a combination of organic chicken manure and liquid organic fertilizer at a dose of 20 L/ha gave the best production of shallots, namely 0.61 kg/ plot (2.44 tons/ha).
