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

Abstrak

Optimum maintenance is required to get a high-quality parent plant. One of the
maintenances is fertilization to ensure the optimal growth of the pepper parent plant. This study
aimed to obtain the optimum rate of urea fertilizer for a one-year-old of the pepper parent
plant. The field experiment used a single factor in a randomized block design (RBD) with five
urea 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 and
400 g plant-1 year-1. The rate of urea influenced the number of internodes and leaf area of the
pepper parent plant. The rate of 315 g plant-1 year-1 urea is the optimum rate for the growth of
the number of the branch of a one-year-old pepper parent plant.
