  • Abstract

    Germination, growth and yield of Dahlia (Asteraceae) flowering plant was made by irrigated with distillery spent wash of different concentrations. Diluted spent wash (1:1, 1:2 and 1:3) were analyzed for plant nutrients such as nitrogen, phosphorous, potassium and other physical and chemical characteristics. Experimental soil was tested for its chemical and physical parameters. Dahlia seeds were sowed in different pots and irrigated with raw water (RW), 1:1, 1:2 and 1:3 spent wash (SW). The nature of germination, growth and yield of seeds was investigated. It was found that, the germination, growth and yield was very good (100%) in 1:3 SW irrigation, while very poor (25%) in 1:1 SW, moderate (80%) in 1:2 SW and 95% in RW irrigation. This concludes that the diluted spent wash can be conveniently used for irrigation purpose without adverse effect on soil.
