Abstract:
The purpose of this study was to determine the effect of liquid organic fertilizer application of rice water waste and magnesium sulfate on flowering and fruiting of siamese citrus outside the season, which was conducted in Bayung Gede Village, Kintamani District, Bangli Regency, from September 2023 to April 2024. This study used a Randomized Block Design consisting of 2 factors arranged factorially. The first factor tested was liquid organic fertilizer of rice water waste (B) with 4 concentration levels, namely B0 = 0 ml/l; B1 = 5 ml/l; B2 = 10 ml/l and B3 = 15 ml/l. While the second factor is the application of magnesium sulfate fertilizer (M) with 4 dosage levels namely M0 = 0 g/tree; M1 = 5 g/tree; M2 = 10 g/tree and M3 = 15 g/tree, each of which was repeated 3 times so that 48 plants were needed. Based on the results of the study, the interaction between the concentration of liquid organic fertilizer of rice water waste and the dose of magnesium sulfate fertilizer significantly affected the variables of the number of harvested fruits and the weight of harvested fruits per tree, very significant effect on fruit diameter and not significant effect on other variables. The highest number of harvested fruits per tree, fruit diameter and harvested fruit weight per tree were obtained at the interaction between liquid organic fertilizer of rice water waste at a concentration of 15 ml/l with magnesium sulfate fertilizer dosage of 15 g/tree, namely 86 fruits; 6.97 cm and 12.03 kg or an increase of 84.27%; 78.72% and 89.15% when compared to without liquid organic fertilizer of rice water waste with no magnesium sulfate fertilizer, namely 46.67 fruits; 3.90 cm and 6.36 kg.
