Penelitian ini bertujuan untuk mengetahui pengaruh pemberian dosis kapur dolomit (CaMg(CO3)2) dan pupuk KNO3 terhadap pertumbuhan dan pembungaan tanaman Jeruk Siam. Penelitian ini dilaksanakan di kebun jeruk, Desa Karanggude, Kecamatan Karanglewas, Kabupaten Banyumas pada bulan Desember 2022 – Maret 2023. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor dan 3 ulangan. Faktor pertama adalah dosis kapur dolomit yaitu 0 kg/tanaman, 3 kg/tanaman, dan 6 kg/tanaman. Faktor kedua dosis pupuk KNO3 yaitu 0 gr/tanaman, 30 gr/tanaman, dan 60 gr/tanaman. Hasil penelitian menunjukkan bahwa pemberian perlakuan dosis kapur dolomit berpengaruh sangat nyata terhadap jumlah tunas vegetatif, jumlah daun baru, panjang tunas vegetatif, diameter tunas vegetatif, dan luas daun. Faktor kapur juga berpengaruh nyata terhadap jumlah tunas generatif. Perlakuan dosis KNO3 berpengaruh sangat nyata terhadap jumlah tunas vegetatif, jumlah daun baru, panjang tunas vegetatif, dan diameter tunas vegetatif. Faktor KNO3 juga berpengaruh nyata terhadap luas daun, jumlah tunas generatif, dan jumlah bunga. Interaksi antara dosis kapur dan pupuk KNO3 berpengaruh sangat nyata terhadap jumlah tunas vegetatif, jumlah daun baru, luas daun, jumlah tunas generatif, jumlah bunga, dan jumlah fruitset.

The purpose of this study was to determine the effect of dolomite lime (CaMg(CO3)2) and KNO3 fertilizers on the growth and flowering of Siamese oranges. This research was conducted in an orange orchard, Karanggude Village, Karanglewas District, Banyumas Regency in December 2022 - March 2023. This study used a Factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was the dose of dolomite lime, namely 0 kg/plant, 3 kg/plant, and 6 kg/plant. The second factor was the dose of KNO3 fertilizer, namely 0 gr/plant, 30 gr/plant, and 60 gr/plant. The results showed that dolomite lime treatment had a very significant effect on the number of vegetative shoots, the number of new leaves, the length of vegetative shoots, the diameter of vegetative shoots, and the area of leaves. The lime factor also has a significant effect on the number of generative shoots. KNO3 dose treatment had a very significant effect on the number of vegetative shoots, the number of new leaves, the length of vegetative shoots, and the diameter of vegetative shoots. The KNO3 factor also had a significant effect on leaf area, number of generative shoots, and number of flowers. The interaction between the dose of lime and KNO3 fertilizer had a very significant effect on the number of vegetative shoots, the number of new leaves, leaf area, number of generative shoots, number of flowers, and number of fruit sets.
