Abstract: An investigation was carried out to determine the chlorophyll content in chrysanthemum (Dendranthema grandiflora) by using SPAD-502 at different level of nitrogen applications in the department of horticulture, Sam Higgingbottom University of Agriculture Technology and Sciences, Prayagraj, (U.P), India, during the winter season 2019. Different level of nitrogen fertilizers were taken as treatments and are applied at an interval of thirty days and chlorophyll content were determined at interval of 15 days. The main objective of this study is to assess the chlorophyll content in response to different level of nitrogen, to evaluate the photosynthetic rate with different levels of nitrogen application and to determine leaf N with different level of N applications in chrysanthemum.
