A pot experiment was conducted during rabi season 2014-15 to study the effects of time of application and concentration of nano zinc sulphide (ZnS) on chlorophyll content of sunflower (Helianthus annuus L). Among the different treatments foliar sprayed nano-ZnS 400 ppm at 35 DAS sowing recorded higher chlorophyll content compare to other treatments which were on par with 500 ppm nano-ZnS sprayed at 35 DAS. However, lowest chlorophyll were recorded under water sprayed treatment.
