| dc.description.abstract | The research of the growth and production of the Samhong mustard (Brassica juncea L.) adding by with nutrients with rice washing water in the Wick hydroponic system had been conducted by using a different concentrations. This research was conducted from October 2021 to December 2021 at Rumah Plastik Jl. Tj. Permai VII No. 116, Kp. Lalang, Sunggal District, Deli Serdang Regency, North Sumatra. This observation used a completely randomized design (CRD) with four concentrations of rice washing water, which were 25% concentration, 50% concentration, 75% concentration and 100% concentration and water used as a negative control and standard, also AB mix as a positive control rate after one week treatment, all concentrations of rice washing water showed a significant effect on all parameters such as plant height, number of leaves, chlorophyll b content, the relative growth, wet weight and dry weight. The best wet and dry weight were obtained from 25% rice washing wate. Therefore, 25% of rice washing water was the best concentration to increase growth and production of Samhong mustard plants. | en_US |
