Washed rice water is produced daily and can enhance and stimulate plant root growth. Washed rice water is rich in B vitamins, minerals, and several micronutrients and macronutrients that play a good role in plant growth. Vitamin B1 can convert high carbohydrates into energy in the bioprocess as an intermediary for the formation of auxin and gibberellin hormones. Pakcoy were chosen because they are commonly consumed with a relatively short harvest period of about 25 to 30 days. This study aims to determine whether or not there is an effect and the best concentration of washed rice water on the growth of pakcoy. The research was classified as an experiment conducted using random group designs, with 20 experimental units, four treatments repeated five times and several concentrations as follows. 0 ml/litre of water as variable control (non-treat), 15 ml/litre of water, 20 ml/litre of water, and 25 ml/litre of water. Data was analysed using the Anacova test with a significance value of 0.001 <0.05, meaning that there is an effect of washed rice water on the growth of pakcoy. A pairwise comparison test was conducted with the following significance values. A) root length (0,000<0.05); B) plant height (0,000<0.05); C) stem diameter (0.102>0.05); D) leaf width (0,000<0.05). Furthermore, bivariate analysis was conducted with the following significance values. A) root length (0.003<0.05); B) plant height (0.002<0.05); C) stem diameter (0.062>0.05); D) leaf width (0.001<0.05). It can be concluded that the application of washed rice water with the best concentration, namely 25 ml/litre of water, affects the growth of pakcoy in the parameters of root length, plant height, and leaf width. © 2024 Author(s).
