Study of Fluoride Toxicity on the Growth and Yield of Wheat (Triticum aestivum L.)

The effect of fluoride toxicity has been studied on growth and yield characters viz. plant height, tillers number, leaves, leaf area, number of ears/ plant, dry wt. /m², Test wt. of 1000 seeds and yield /m² of wheat (Triticum aestivum L.) of two varieties, WL75 and UP2003. The experiments were conducted at C.C.R. (P.G.) College Muzaffarnagar in the year 2002 and 2003. Simple Randomized Blocks Design was followed with five conc. of Sodium fluoride such as 10, 25, 50, 100 and 200 ppm along with control for four replications. The results were found significant. 100-200 ppm doses of sodium fluoride were found toxic for both the varieties of wheat.
