Curly mustard (Brassica juncea L.) is a commercially important leafy vegetable. This study evaluated the effects of vermicompost dosage and liquid organic fertilizer (LOF) concentration on the growth and biomass production of curly mustard grown in polybags. The experiment used a factorial randomized block design with three vermicompost levels (45, 75, and 105 g/polybag), four LOF concentrations (0, 6, 10, and 14 mL/L), and three replications. Vermicompost dosage significantly affected shoot fresh weight, shoot dry weight, root length, root fresh weight, and root dry weight, but did not significantly affect plant height, leaf number, or leaf width. LOF concentration significantly affected all observed variables except leaf number. The interaction between vermicompost and LOF significantly affected all variables except leaf number. The best treatment combination varied among variables: D2C3 produced the greatest plant height, shoot fresh weight, and root fresh weight; D3C4 produced the greatest shoot dry weight; D3C2 produced the longest roots and greatest root dry weight; and D1C3 produced the greatest leaf width. Therefore, no single treatment combination was consistently superior across all measured variables.
