A study was carried out at CSIR-CIMAP, RC. Hyderabad (India) to study the impact of coppicing time on the oil percent and its chemical composition of different cultivars of lemongrass using a randomized block design. The freshly harvested herb was used for the hydro-distillation for essential oil, and subsequent chemical analysis. The chemical components identification of the essential oil was performed by GC-MS. In the results coppicing time influenced significant changes in the essential oil content, essential oil yield, and its chemical composition especially, total citral, and geraniol content. The four top rankers varieties/cultivars of lemongrass for the essential oil yield were CIM-Shikhar > Krishna > CKP-25 > CIMAP-Suwarna; for the essential oil content CIM-Shikhar > Krishna > CIMAP-Suwarna > Praman; for total citral content Nima > CIM-Shikhar > Krishna > Pragati, and for the total geraniol content Himrosa > CN-5 > Tawirosa > Kalam, respectively. Therefore, we can recommend these varieties/cultivars for commercial cultivation in large areas under the semi-arid region of south India.
