The objective of this research was to study the effects of indigo sludge compost on growth and yields of Chinese kale (Brassica alboglabra). The experiment was set as randomized complete block design (RCBD) with 4 treatments and 4 replications; treatment 1; control, treatment 2; fresh indigo sludge, treatment 3;
indigo sludge compost and treatment 4; cow dung manure at Plant Science Field, Faculty of Agricultural Technology, Sakon Nakhon Rajabhat University between December, 2015 to March, 2016. The results showed that indigo sludge compost could produce highest growth and yield of Chinese kale, as well as, plant height,canopy width, number of leave, fresh weight and dry weight. The plant height were 35.19 cm, canopy width were 28.92 cm, 7.15 leave /plant, fresh weight were 118.49 g/plant and dry weight were 9.56 g/plant. Fresh weight in cow dung manure was second, and then fresh indigo sludge and the control treatment without
fertilizer, 70.16, 68.52 and 52.80 g/plant, respectively and were significantly different (P<0.01).
