The present investigation “Impact of controlling treatment on African marigold (Tagetus erecta L.) with special reference to Economic parameters” was carried out at the Department of Horticulture, Gochar Mahavidhyalaya, Rampur Maniharan, Saharanpur affiliated by CCSU, Meerut, Uttar Pradesh during 2017-18. During the study period various treatments were given to accelerate the growth of flowering and vegetative parameters of the selected species. All the vegetative and flowering parameters like plant spreading, diameter of plant, number of primary and secondary branches and in the flowering parameters i.e. bud initiation, number of flowers per plant, total flower yield was recorded maximum under T6 (75% RDF + vermicompost + azotobacter) treatment, while all the values were found minimum under control treatment and there was a big difference between the output of said treatment. Economic parameters were found very close to the studied vegetative and flowering parameters as given treatment played a pivotal role to enhance the economic gain from selected flowering plant and the maximum CBR was also recorded under T6 (75% RDF + vermicompost + azotobacter) treatment while the minimum CBR was recorded under control treatment.
