Studies of Distillery Spent Wash Irrigation on Germination and Growth of Chrysanthemum indicum and Polianthes tuberosa Flowering Plants
Germination and growth of Chrysanthemum indicum (Asteraceae) and Polianthes tuberosa (Agavaceae) seeds were made by irrigation with distillery spent wash of different concentrations. The spent wash i.e., primarily treated spent wash (PTSW), 1:1, 1:2, and 1:3 was analyzed for its plant nutrients such as nitrogen, phosphorus, potassium and other physical and chemical characteristics. Experimental soil was tested for its physico-chemical parameters. Seeds of Chrysanthemum and Polianthes were sown in different pots and irrigated with raw water (RW), differently diluted spent wash. The nature of germination of seeds and growth was studied. It was found that the germination 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 irrigations. Hence, spent wash can be used as irrigation medium at regular dilution.
