Optimization rate of urea fertilizer for one-year-old pepper (Piper nigrum L.) parent plant

Optimum maintenance is required to get a high-quality parent plant. One of themaintenances is fertilization to ensure the optimal growth of the pepper parent plant. This studyaimed to obtain the optimum rate of urea fertilizer for a one-year-old of the pepper parentplant. The field experiment used a single factor in a randomized block design (RBD) with fiveurea rate levels, and each treatment was repeated three times. Treatment levels of urea rate,namely 0 g plant-1 year-1, 100 g plant-1 year-1, 200 g plant-1 year-1, 300 g plant-1 year-1 and400 g plant-1 year-1. The rate of urea influenced the number of internodes and leaf area of thepepper parent plant. The rate of 315 g plant-1 year-1 urea is the optimum rate for the growth ofthe number of the branch of a one-year-old pepper parent plant.
