Productivity and Cost Analysis of Chinese Cabbage (Brassica rapa) in Hydroponic Wick System Based on Formula

Organic fertilizers have emerged as a vital alternative to address the environmental and human health concerns associated with the use of inorganic fertilizers. This research aims to develop the right nutrient formula for cultivating Pak Choi (Chinese cabbage) using the Wick hydroponic system. Considering factors such as variety selection, cultivation system, and nutrient requirements, this study explores the productivity of Pak Choi plants and the cost structure of cultivation. The research methodology involves testing various nutrient formulas and observing post-harvest plant metrics like wet weight, leaf width, leaf count, and plant height. Descriptive analysis and ANOVA tests reveal significant differences among treatments in plant morphology. Furthermore, cost analysis highlights the efficiency and profitability of each treatment, with Treatment F3 emerging as a cost-effective option with low expenses and good gross profit. These findings offer practical guidance for farmers to enhance vegetable production economically and sustainably in hydroponic cultivation.
