Archana Chakravarty, R. N. Yadava

Abstract: The present study was conducted to investigate the allelopathic eects of stems of aqueous extracts of Pithecellobium dulce (Roxb. ) Benth and stems of Bauhinia racemosa Lam at different concentration ( 0, 25, 50, 75 and 100 %). The results obtained from experimental findings shows that pure extract of Pithecellobium dulce (Roxb. ) Benth, inhibited the growth of seeds germination of Trigonella foenum-graecum, whereas pure extract of Bauhinia racemosa Lam. , promoted the seed germination of Trigonella foenum-graecum. Therefore these plants can be used as natural herbicides and natural fertilizers respectively.
