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.Keywords

Fluoride in higher concentrations is toxic to the plants. The present experiment was conducted at C.C.R. (P.G.) College, Muzaffarnagar during the years 2002-2003. Simple randomized block design with four replications and six treatments including control was followed. The concentrations of NaF were 10, 25, 50, 100 and 200 ppm. The first spray of NaF solution was done after 30 days of sowing. Subsequent sprayings and recording of data was done fortnightly till harvesting of the crop. The effect of sodium fluoride was found toxic to both the varieties of chick pea viz. Pusa 256 and K 850.Keywords

Fluoride and SO2 are air pollutants which are toxic to vegetation human lives and animals. 100-200 ppm doses of NaF are more toxic than 10 ppm. 10 ppm dose does not affect any plant or animal. Thus it is considered under threshold limit. The present experiment was conducted at C.C.R. (P.G.) College, Muzaffarnagar during the years 2002-2003 to study the effect of fluoride toxicity on chlorophyll, protein percentage and energy content in wheat and Chickpea. The Chlorophyll content in green leaves was studied on 60th day of sowing. Protein and energy contents were studied after harvesting with the oven dried plant material at 80°C temperature 100-200 ppm concentrations of NaF were found toxic to wheat and chickpea.
