Allelopathic effects of the neem and eucalyptus were analyzed on the growth and germination of wheat (Triticum aestivum var. Desi) in a laboratory of IGAEERE, Jiwaji University, Gwalior. The aqueous extract concentrations of neem and eucalyptus used in the experiment were 25%, 50% and 100% w/v prepared by dissolving the leaf powder of 25 g, 50 g and 100 g of the neem and eucalyptus plants in 500 ml distilled water. The aqueous extracts of various concentrations of both these plants showed a remarkable allelopathic effect on the growth and germination of the wheat. The inhibitory allelopathic effect of both these plants directly increases as the concentration of the extract increases. However, the allelopathic effect of eucalyptus extract was found more than neem on the growth and germination of wheat. The present study has very important implications as the eucalyptus and the neem has been used extensively as a part of Agroforestry in various parts of India.
