<![CDATA[This study aimed to determine the effect of liquid organic fertilizer from catfish farming wastewater (POCale) and chicken manure on the growth and yield of bok choy (Brassica rapa L.) on Inceptisol soil. The study used a Factorial Randomized Block Design with two factors, namely the dose of POCale (0, 100, 200, and 300 ml/L/plot) and the dose of chicken manure (0, 0.5, 1.0, and 1.5 kg/plot). The parameters observed included plant height, number of leaves, fresh weight per sample, fresh weight per plot, and net weight per plot. The results showed that POCale administration did not significantly affect all parameters of bok choy growth and yield, although the highest dose (300 ml/L/plot) gave the best quantitative value. In contrast, the application of chicken manure had a very significant effect on increasing plant height, number of leaves, and fresh weight of bok choy plants, with a dose of 1.5 kg/plot producing the best performance. The interaction between POCale and chicken manure did not have a significant effect, but the combination of the two at the highest dose yielded the best results numerically. This study concluded that chicken manure was more effective in increasing bok choy growth and yield on Inceptisol soils compared to liquid organic fertilizer from catfish farming waste.]]>
