Objectives and Key Themes

The main objective of this research was to investigate the effects of plant spacing and harvesting age on the growth, biomass and essential oil yield of rose-scented geranium (Pelargonium graveolens L. Herit). This study aimed to identify optimal planting distances and harvest times for maximizing geranium yield and oil quality. The study was conducted at the Wondo Genet Agricultural Research Center in Ethiopia.

• Influence of plant spacing on geranium growth, biomass, and oil yield.
• Impact of harvesting age on geranium growth, biomass, and oil yield.
• Combined effects of plant spacing and harvesting age on geranium essential oil yield and composition.
• Determination of optimal planting distances and harvest times for maximizing geranium production.
