Abstract

This study aimed to analyze the growth and yield responses of pakcoy (Brassica rapa L.) var. Nauli F1 to the application of NPK fertilizer and plant spacing arrangements. The experiment was conducted using a 3×3 factorial Randomized Complete Block Design (RCBD) with six replications. The factors tested consisted of NPK fertilizer doses (0, 10, and 20 g/plot) and plant spacing (15×15 cm, 20×20 cm, and 25×25 cm). The observed parameters included plant height, number of leaves, leaf length, leaf width, plant weight with roots, and plant weight without roots. Data were analyzed using the Least Significant Difference (LSD) test at the 5% significance level. The results showed that the combination of NPK fertilizer doses and plant spacing significantly affected all observed parameters. In general, increasing fertilizer doses combined with wider spacing improved plant growth and yield. The highest yield was obtained at 20 g/plot with 25×25 cm spacing, while the control treatment (without fertilizer) resulted in the lowest growth and yield. However, the moderate fertilizer dose showed good efficiency in several growth parameters.
