The research aimed to find out the efforts to produce off-season orange fruit and increase the quality of fruit through the application of potassium nitrate and agrodyke organic fertilizer. The study used a factorial randomized block design with 2 treatment factors. The first factor is the flower induction application using potassium nitrate (K) consisting of 3 levels, namely (K0 = 0 g/tree), (K1 = 20 g/tree), and (K2 = 40 g/tree). While the second factor is the application of agrodyke organic fertilizer (P) consisting of 4 levels, namely (P0 = 0 g / tree), (P1 = 15 g/tree), (P2 = 30 g / tree) and (P3 = 45 g/tree). There are 12 combination treatments and each of them is repeated 3 times so that 36 tree plants are needed. The results showed the interaction between potassium nitrate treatment with agrodyke organic fertilizer treatment had no significant effect on all observed variables. Potassium nitrate treatment and agrodyke organic fertilizer can significantly improve the quality of orange citrus fruit out of season physically. In the treatment of potassium nitrate 40 g/tree, the weight of the harvested fruit per tree was obtained, the weight per fruit and the highest fruit diameter were 13703.90 g; 99.92 g and 6.81 cm or an increase of 62.24%; 16.32% and 9.49% compared with no treatment of potassium nitrate which is 8446.60 g; 87, 42 g and 6.22 cm.
