Climate change has a significant impact on crop failure and agricultural production. To overcome this issue, fertilization strategy is needed to increase plant growth. Magnesium Sulphate (MgSO4) role in photosynthesis, enzyme activation, and synergism with other nutrients plays big part in increasing plant growth and harvest. Complementing NPK fertilizing with MgSO4 can be a solution to fulfill nutrient needs with lower input and higher effectivity. This study aims to find best formula of MgSO4 complementing NPK fertilizer in improving shallot growth. Experimental method was conducted using Randomized Complete Group Design (RCBD) with 9 treatments and 3 replications, namely: control, standard NPK (Urea 250 kg ha-1, SP-20 130 kg ha-1, and KCL 60 kg ha-1), MgSO4 (300 kg ha-1), and six combinations of MgSO4 with NPK. The results showed that application of MgSO4 combined with NPK fertilizer significantly increases the growth of shallots. The addition of 300 kg ha-1 of MgSO4 with 3/4 doses of NPK fertilizer effectively increased shallot growth as indicated by the highest plant height, number of leaves, and number of tillers.
