Influence of textile mill wastewater irrigation on the growth of sorghum cultivars

Abstract

The aim of the presented study was to evaluate the suitability of textile mill wastewater (treated and untreated) at different concentrations (0, 6.25, 12.5, 25, 50, 75, and 100%) for irrigation purposes. Effect of textile mill wastewater on germination, delay index, physiological growth parameters and plant pigments of two cultivars of sorghum was studied. The textile effluent did not show any inhibitory effect on seed germination at lower concentration (6.25%). The other reported plant parameters also followed the similar trend. Seeds germinated in 100% effluents but did not survive for longer period. It has also been concluded that effect of the textile effluent is cultivar specific and due care should be taken before using the textile mill wastewater for irrigation purpose. © 2008, Penkala Bt.
