Abstract

Pakcoy (Brassica rapa L.) is a green vegetable plant that is in great demand by people from children to adults, because it has very high nutritional value. Cultivation of pak choy plants on dry land with a dry climate requires the adoption of technology such as wick fertigation in verticulture. The aim of this research was to determine the effect of providing nitrogen fertilizer sources and types of ameliorant on the growth and yield as well as nitrogen uptake of pak choy (Brassicca rapa L.) plants. This research method uses a split plot design (RPT) with 2 factors consisting of a main plot and a subplot. The main plot is N fertilizer consisting of urea, POC, and urea + POC. Subplots are ameliorants consisting of soil, soil: biochar (1:1), soil: compost (1:1) and soil: biochar: compost (1:1:1). Thus, 12 treatment combinations were obtained which were repeated 3 times, resulting in a total of 36 experimental combinations. The research results showed that the interaction of the N fertilizer source and the type of ameliorant had a real influence on the observation of stem diameter and root length with the best treatment of urea+POC with the type of soil ameliorant: biocar: compost (1:1:1). The source of N fertilizer has a significant effect on shoot dry weight, harvest index and N uptake, where the best treatment is urea+POC fertilizer. The type of ameliorant had a significant effect on the number of leaves at 28 DAT and N content where the best treatment was soil: biochar: compost (1:1:1) showing the highest results when observing the number of leaves at 28 DAP and N content. Treatment of the type of soil ameliorant: biochar: compost (1:1:1) shows the best results.

Abstract

Pakchoi productivity in dryland areas is often constrained by water availability and suboptimal nutrient management strategies. However, the combined role of organic growing media, boron supply, and controlled irrigation in a vertical-wick fertigation system under dryland conditions remains underexplored. This study aimed to assess the presence of boron in compost- and biochar-modified growing media under water stress, which affects the morphophysiology of pakchoi in dryland conditions, using a vertical system with wick fertigation. The study was arranged in a split-plot design with two watering frequencies and a growing media formulation based on soil, compost, and biochar, with added boron. The results showed that watering frequency and boron-based growing media significantly affected leaf number, shoot and root biomass, root characteristics, and chlorophyll content. Consistent daily watering resulted in better growth and yield compared to watering every other day. Optimized combinations of regular irrigations and appropriate boron application enhanced biomass accumulation and chlorophyll content, indicating improved plant performance. These findings indicate that regular water management through a wick fertigation system, combined with organic growing media formulation and appropriate boron dosage, can significantly enhance pakchoi growth and productivity in dryland conditions. Importantly, this study provides a practical and scalable strategy for improving vegetable production under water-limited conditions.
