When we tested various industrial wastewater samples collected from different industries they shown high amount of toxic chemical components, and the samples are unfit for irrigation or for any kind of activity. Irrigation of untreated wastewater for long time leads to soil pollution by accumulating toxic salts in the soil. The regular growth of plant get effected by this water like improper growth, low chlorophyll content, low carotenoids content, low yield, etc. Three different types of oil yielding plants (Mustard, Ground nut and Sunflower) and three different types of vegetable crops (Tomato, Chilly and Brinjal) has grown by using different industrial wastewater samples. The primitive parameters of vegetative growth (imbibition, seed germination and vigour index) and nutritional components (chlorophyll a, b and carotenoids) have been observed in all the samples after growing for a particular time period. The imbibition test of seed samples in industrial wastewater samples have not shown significant variation compared to imbibition in distilled water sample. All the seeds in all wastewater samples absorbed almost negligible difference but in the percentage of germination there is significant difference. The tests for nutritional compositions have also shown significant decrease in chlorophyll a, b and carotenoids in all varieties.
