Abstract: The research work entitled on “Ameliorative Effect of Salicylic acid, Trichoderma and Mycorrhiza in Pearl Millets (Pennisetum glaucum L.) Under Fluoride Toxicity”. The present research work was carried out during Kharif season in the Department of Agronomy on the terrace of Block-25 School of Agriculture, Lovely Professional University, Jalandhar, Punjab with one variety of pearl millets Moti Bajra. The result indicates that average plant height was significantly reduced with 9.3%, 18.58%, 3.09% and 18.81% when exposed to fluoride stress (T1) as compared to control (T0). The stem girth of the plant was significantly increased by 4.6% at 30DAS, 8.6% at 60DAS, 2.7% at 90DAS and 36.8% at 120DAS of interval in controlled treatment (T0) as compared to treatment where fluoride toxicity was created artificially in (T1). The chlorophyll content was reduced with 39.4% at 30DAS, 6.6% at 60DAS, 24.3% at 90DAS and 46% at 120DAS when plant exposed to fluoride stress as compared to control treatment. In the application of mycorrhiza and salicylic acid in the presence of fluoride toxicity, the content of chlorophyll was increased compared to fluoride stress. The application of mycorrhiza helps to mitigate the stress of fluoride and provide sufficient nutrients to the plant that increases the growth, morphological and biochemical parameters of the plant.
