Abstract

This research is projected to answer questions and urgencies related to the reasons for Pak Choi's lack of productivity and also be able to answer recommendations for RULOF composition, which are interacted with the selection of the best superior varieties. This research aims to analyze the effect of RULOF, varieties, and interactions with both. The research was conducted at the Green House of the Faculty of Agriculture, University of Jember, in November-December 2022. A factorial Completely Randomized Design (CRD) was used, which consisted of 2 factors with three replications. Factor 1 = RULOF, with four levels: P0 (0 ml/liter), P1 (100 ml/liter), P2 (200 ml/liter), and P3 (300 ml/liter). Factor 2 = Varieties: V1 (Green), V2 (Nauli F1), and V3 (Emone 26). The ANOVA results show that all parameters are significant with the influence of RULOF. Varieties affect all parameters except root length. The interaction is insignificant for all parameters except the wet weight. The 200 ml/liter RULOF (P2) and Nauli F1 (V2) treatments showed the highest average value of all variables.
