Abstract: Studies were conducted to study the germination, growth and yield of leguminous forages; Lucerne, Cowpea and Horse gram irrigated with distillery spent wash of different concentration. The spent wash in the ratio of 1:1, 1:2, and 1:3 was used and analysed for their plant nutrients such as Nitrogen, Phosphorous, Potassium and other physical and chemical characteristics. Experimental soil was tested for its chemical and physical parameters. Lucerne, Cowpea and Horse gram seeds were sowed in different pots and irrigated with raw water (RW) along with spent wash in the ratio of 1:1, 1:2, and 1:3. The results of the germination, growth and yield were studied. It was found that the germination, growth and yield was very good in 1:3 spent wash irrigation compared to 1:1 spent wash, 1:2 spent wash and raw water irrigation for all the plants. Hence, spent wash can be expediently used as a medium for irrigation in specific dilution without harming the atmosphere, water and soil.
