ABSTRACT
This study was conducted to understand the Effect of Combination of Nitrogen, Phosphorus, and Potassium Fertilizer Doses which can produce high rosella
plants. This study was conducted on 10 October 2017 until May, 20 2018 held at the village of Antirogo, Kabupaten Jember. This study uses a Randomized Block
Design (RCBD) non factorial. The combination dose of fertilizer treatment is T1 = 7 grams of Urea, 10 grams of SP36, and 5 grams of KCl, T2 = 10 grams of
Urea, 13 grams of SP36, and 5 grams of KCl, T3 = 10 grams of Urea, 10 grams of SP36, and 8 grams of KCl, T4 = 7 grams of Urea, 13 grams of SP36, and 8
grams of KCl, T5 = 10 grams of Urea, 13 grams of SP36, and 8 grams of KCl, T6 = 13 grams of Urea, 13 grams of SP36, and 8 grams of KCl, T7 = 10 grams of
Urea , 16 grams of SP36, and 8 grams of KCl, T8 = 10 grams of Urea, 13 grams of SP36, and 11 grams of KCl, T9 = 13 grams of Urea, 16 grams of SP36, and 11
grams of KCl. Significant variance results were tested further by Duncan's Multiple Range Test (DMRT) with a level of 5%. The results of the analysis
showed that the combination treatment of Nitrogen, Phosphorus, and Potassium fertilizers showed no significant difference to all observation parameters
including the height of the rosella plant, the number of branches of rosella production, the number of calyx and capsules, the wet weight of calyx and
capsules, and the dry weight of calyx and capsules.
