This study aims to determine the effect of watering frequency, type of mulch, and bamboo biochar on the characteristics of Entisol soil which will influence the growth of shallot plants. This research was conducted from March to September 2023 at in Srigading Village, Sanden District, Bantul Regency and laboratory analysis at the Kuningan Soil Laboratory, General Soil Laboratory, Soil Chemistry and Fertility Laboratory, and Soil Physics Laboratory, Soil Department, Faculty of Agriculture, Gadjah Mada University, Yogyakarta. This research was arranged in a split split plot design consisting of 3 factors with 3 replications. The first factor is the frequency of watering which consists of 2 treatment levels, namely: P1 (watering once a day) and P2 (watering once every four days), the second factor is the type of mulch which consists of 3 treatment levels, namely: M0 (without mulch), M1 (plastic mulch), and M2 (straw mulch), the third factor is the dose of bamboo biochar which consists of 2 levels, namely: B0 (0 kg/m2 or without biochar) and B1 (1 kg/m2). The results showed that watering frequency, the application of mulch, and biochar had a significant effect on potassium uptake by tuber and phosphor uptake by tuber, also increasing soil pH, organic carbon, and potassium availability at 50 days. The best result is in the combination of P2M2B0.
