Abstract
The term of allelopathy, whereby one plant chemically interferes with seed germination, growth and development of others has been documented for over 2000 years. Allelochemicals are secondary metabolites of plants, released into the nearby environment through volatilization, leaching, root exudation and decomposition of residues. This experiment was aimed to examine the allelopathic effect of aqueous extracts of  Eucalyptus leaves on seed germination and early growth of mungbean. Two pot experiments were carried out at Agronomy laboratory and research field, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during February 2017 to March 2017 to find out the response of mungbean variety on Eucalyptus camaldulensis leaf extract. For screening four mungbean varieties (BARI Mung-3, BARI Mung-4, BARI Mung- 5 and BARI Mung-6) were tested with five levels of Eucalyptus camaldulensis leaf extract as allelopathic chemical (0, 5, 10, 15 and 20% concentration) for 8 DAS in small plastic pot.  The  germination rate of mungbean varieties was delayed and germination percentage was reduced with increasing leaf extract concentration compared to control. Fresh and dry weight of seedling was also lessened significantly compared to control. The inhibitory effects of  Eucalyptus leaves were augmented as the extract concentration increased. These findings revealed that eucalyptus leaf extract adversely affect the germination and seedling growth of mungbean.
