Effect of six levels of fluoride viz.0 (T₁), 50 (T₂), 100 (T₃), 200 (T₄), 250 (T₅) and 300 (T₆) mg fluoride kg^-1 soil on morphological parameter of wheat genotype HUW-234 was studied under pot culture during 2016-17 and 2017-18. Observations were recorded at 30 days interval. Elevated concentrations of fluoride significantly reduce shoot dry matter, leaf area, relative growth rate (RGR) and net assimilation rate (NAR) while plant height at 50 mg fluoride kg^-1 soil was marginal stimulated but at higher concentration it declined. It is concluded that elevated fluoride level in soil causes reduction in plant growth and development primarily by reducing photosynthetic area and NAR.
