Allelopathic potential of Eucalyptus on germination and early seedling growth performance of agricultural crops
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 6, Issue 6
Abstract
Plants may favourably or adversely affect other plants through allelochemicals, which may be released directly or indirectly from living or dead plants (including microorganisms). This research was undertaken in the nursery of Areka Agricultural research centre that crops grown in a pot experiment laid in a completely randomized design. Water extracts of young and fresh Eucalyptus- camaldulensis and Eucalyptus-globulus leaves were used as a treatment. Four agricultural crops (haricot-bean, faba-bean, wheat and maize) were used as recipients of the extracts, with the objective to evaluate the effects of water leaves extracts on the germination and early seedling growth of the crops. Results suggested that both tree species induced inhibitory effects on germination and growth of all crops compared to the control treatments except for some independent parameters of some crops. Eucalyptus globulus has more inhibitory effect on all crops than Eucalyptus camaldulensis. Thus, it is recommended that these crops should not be planted very close or not to Eucalyptus trees or seed rate of the crops should increase one to two times this is due to the likely adverse effects of Eucalyptus on seed germination and other seedling growth parameters.
