| Abstract | Rosa damascena Mill. is cultivated for its high-value essential oil in different parts of the world. The flower yield and the composition of essential oil of R. damascena are strongly affected by a number of factors. Nevertheless, the interactive effects of foliar application of plant nutrients and kinetin and its time of application on yield and secondary metabolites profile of R. damascena under acidic conditions are still unclear. Thus, a field experiment comprising two different times of spray and five foliar spray treatments was conducted to test the hypothesis that flowering behavior and secondary metabolites profile can be modified through proper nutrient supply at right time. The foliar spray at flower bud appearance stage (S$_{2}$) significantly (P ≤ 0.05) increased flower yield by about 10.0 % compared with the foliar application at axillary bud development stage (S$_{1}$) during both years, regardless of plant nutrients. Among the foliar spray treatments, kinetin at 0.20 g L$^{−1}$ registered about 23–39 % higher flower yield compared with the water spray control; however, remained statistically at par (P ≤ 0.05) with Ca(NO$_{3}$)$_{2}$ at 4.06 g L$^{−1}$. Moreover, the percentage of major fragrance-bearing compounds of essential oil (β-citronellol + nerol, linalool, E-geraniol, and Z-citral) was marginally increased with Ca(NO$_{3}$)$_{2}$ compared with kinetin treatment. However, the percentages of major hydrocarbons, nonadecane and heneicosane, were noticeably increased when kinetin was applied at S$_{1}$. Foliar application of kinetin and Ca(NO$_{3}$)$_{2}$ might be done to improve flower yield and essential oil content in R. damascena flowers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
