Abstract

Shallots are not a basic need, but consumer demand for shallots reaches 119,080 tons/year (EWS, 2020) to be used as raw material for industry and household consumers. So far, in Riau, to meet consumer demand for shallots, they have to be imported from other regions. This is because shallot production in Riau Province is still low, namely 507 tons/year (Central Bureau of Statistics and Directorate General of Horticulture, 2019). Low shallot production in Riau is due to the increasingly limited availability of fertile land in Riau due to the expansion of industrial openings, the conversion of agricultural land to housing or settlements and plantations, so an alternative is needed by utilizing marginal land, including ultisol soil."The purpose of this study was to determine the effect and get a good interaction between humic acid and NPK fertilizer on shallot plant growth."This research was carried out experimentally using a factorial Completely Randomized Design (CRD), which consisted of two" factors namely A (Humic Acid) which consisted of 3 levels, and factor N (NPK fertilizer) which "consisted of 3 levels, and each there were 3 replications, the number of experimental units was 27 plots, each plot consisted of 3 plants and 2 plants as samples, so that the total plant was 27x3 = 81 plants.. Observations were made at the end of the study, namely, while the parameters observed were as follows: "Plant Height" (cm), "Number of Leaves" (strands), "Number of tubers (cm2), Diameter of tubers (cm), Number of tubers (fruit) and Tuber weight (grams). The results showed that the administration of humic acid 10 g/polybag and NPK 2 g/polybag had the best results on shallot growth and production.
