  An experiment was conducted on naturally occurring growth substances in aqueous extracts of some common weeds viz., Bathua (Chenopodium album), Bhijli ghas (Striga densiflora), Shetdrone (Leucus aspera), Mutha (Cyperus rotundus ), Chapra (Eleusine indica) and Khude Anguli (Digitaria ischaemum) with the attempt for chemical investigation on effective extracts. Boiled and unboiled extracts of all the weed species under test significantly reduced and delayed germination of wheat and jute seeds compared with control. The highest germination (96 and 85.3%) and maximum growth of wheat and jute were observed in seeds treated with control. The effect of boiled and unboiled extracts of Bathua (Chenopodium album) showed the lowest germination in seeds of wheat. The root and shoot length of wheat and jute were also decreased in presence of the weed extracts. The thin layer chromatography (TLC) examination of crude extract of Khude Anguli (Digitaria ischaemum) showed four separate compound at hex: ethyl acetate (20:1, v/v) and the crude extract of Bathua (Chenopodium album) showed three separate component at hex: ethyl acetate (10:1, v/v).
