Understanding the impact of wastewater on plant growth is crucial for sustainable agricultural practices and environmental management. This study aims to explore how wastewater affects the growth and biochemical parameters of lentil plants. An experiment was conducted in the Biochemistry Department at Hemwati Nandan Bahuguna Garhwal University, Srinagar, Uttarakhand, India, to investigate these effects. The study focused on assessing the impact of wastewater on the growth and biochemical parameters of Lens esculentus (lentil). Thirty pots (20 cm high, 12 cm diameter) were selected for the study. In 15 pots, wastewater was applied, while the remaining 15 pots received fresh water. The results indicated that the wastewater had a negative impact on seedling growth of the lentil. Seedlings grown with wastewater had lower biomass and length than those grown with fresh water. The protein content in the seeds treated with fresh water was higher than those treated with wastewater, while the carbohydrate content was higher in the early stages but decreased later. The chlorophyll estimation showed higher concentrations in the seedlings grown with fresh water. In the initial stage, the root length and shoot length of the plants irrigated with the wastewater were lower than the fresh water. However, after the 20th day, the root length and shoot length of plants in wastewater treatment significantly increased and surpassed the fresh water treatment. At the 70th day, the root length and shoot length of the plants in wastewater treatment were 9.44±0.29 cm and 14.86±1.58 cm, respectively, indicating that plants in wastewater treatment were able to absorb more nutrients. Therefore, the study suggests that wastewater should be avoided during germination, and it can be used for irrigation after the 20th day of growth. Overall, the study highlights the potential benefits and drawbacks of wastewater as an irrigation source and provides guidance for its safe and effective use in lentil.
