Abstract
The objective of this study was to determine the effect of intercropping of fodder crops on growth and yield attributes of the essential oil-yielding multi-harvest aromatic plant geranium (Pelargonium graveolens L. Her. ex. Ait) under field conditions during 2005–2007. In addition aggressivity, land equivalent ratio (LER), area time equivalent ratio (ATER) and land use efficiency % (LUE%) as an index of intercropping advantage were determined to assess the resource use efficiency of intercropping systems. The main crop geranium was intercropped with oat (Avena sativa L.) and berseem or Egyptian clover (Trifolium alexandrum L.) in different combinations. All crops were also grown in pure stands. The study indicated that the growth and yield of geranium was affected at first harvest compared to sole. But the second harvest in different intercropping systems compared to sole did not affect biomass and oil yield of geranium. Intercrops produced bonus yields over and above that of geranium. The resource use efficiency values were higher in intercropping systems over sole geranium. The study clearly showed that geranium-based intercrop treatments might provide the highest total yield as well as resource use efficiency.
