Abstract
India is one of the top ten industrialized countries of global importance. But industries release waste products, which exert negative influences by causing toxicity to biotic organisms and environment. Liquid wastes of industries termed as effluents are characterized with possession of organic and inorganic compounds that evolve with varying levels of toxicity based on the type of industry and its bi-product. Recycling of treated effluent serves as an alternative to tie over water scarcity in sustainable agriculture. On the other hand, dilutions of industrial effluents serves as growth stimulants at an optimal concentration and influences the seed and seedling quality characters and aids in improving the productivity of crops. The safe levels of dilutions expressing the seed invigourative effect are reviewed hereunder, which could serve as a solution for disposal of effluent in agriculture in an effective manner.
Keywords: Industrialization, effluents, toxicity, dilution, seed invigoration.
