<![CDATA[Sustainable agriculture encourages the use of natural materials as alternatives to synthetic chemicals. This research aims to determine the effect of natural plant growth regulators (PGR) derived from shallot extract, banana corm, and water hyacinth root on the growth of pakcoy (Brassica rapa L.) Nauli F1 variety. This research was conducted at the experimental field in Puseurjaya, East Telukjambe, Karawang Regency, from February to March 2026. The method used was an experimental method, and the experimental design applied was a single-factor Randomized Complete Block Design (RCBD) with 7 treatment levels and 4 replications, namely: A (Without PGR/Control); B (Shallot Extract 10 ml/L); C (Shallot Extract 20 ml/L); D (Banana Corm Extract 80 ml/L); E (Banana Corm Extract 160 ml/L); F (Water Hyacinth Root Extract 75 ml/L); G (Water Hyacinth Root Extract 150 ml/L). The research results were analyzed using the F-test and further tested with the Duncan Multiple Range Test (DMRT) at a 5% significance level. The analysis showed that the application of various natural PGRs had a significant effect on the plant height parameter at 28 days after planting (DAP), with the highest average value of 19.75 cm obtained in the E treatment (Banana Corm Extract 160 ml/L)]]>
