Increasing shallot yields by using solid organic fertilizer and liquid organic fertilizer on dryland

Abstract

Abstract Palu’s local shallot are very popular because they have a distinctive texture, taste and aroma. This research aims to determine the effect of the dose of cow manure and the concentration of liquid organic fertilizer on the growth and yield of the Palu Valley variety of shallots. The research was carried out in Bulupountu Jaya Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi, from May 2023 to September 2023. The research used a randomized block design (RBD) with a factorial pattern. The first factor was the dose of cow manure which consisted of 3 levels, namely: S0 = no cow manure, S1 = 10 tons/ha and S2 = 20 tons/ha. The second factor was the fertilizer concentration. liquid organic which consists of 3 levels, namely: H1= 5 mL/L water and H2= 10 mL/L water, and H3 = 15 mL/L water. Each experimental unit was repeated 3 times so that there were 27 experimental units. The research results showed that there was an interaction between the dose of cow manure and the concentration of herbafarm’s liquid organic fertilizer on plant height, number of leaves, bulb diameter, fresh weight of bulbs and shallot bulb yield per hectare. Cow manure treatment with a dose of 20 tons/ha and a liquid organic fertilizer concentration of 15 mL/L of water gave the highest yield of shallot compared to other treatments.
