    POTENCIES OF SOME SELECTED VEGETABLES IN BANGLADESH AS BIO-HERBICIDE
    (DEPT. OF AGRICULTURAL CHEMISTRY, 2016) ISLAM, MD. KABIRUL
    An experiment was conducted during the period of December 2016 to August 2017 at the Laboratory of the Agricultural Chemistry and net house of Sher-e- Bangla Agricultural University Dhaka-1207, Bangladesh to evaluate the potencies of some selected vegetables in Bangladesh as bio-herbicide. Treatment as six levels of aqueous solution of ten vegetables (potato, tomato, radish, bottle gourd, sweet potato, danta, cauliflower, cabbage, common bean, helencha) i.e. P 1 =0 ppm, P 2 = 1 ppm, P 3 = 2 ppm, P 4 = 3 ppm, P 5 = 4 ppm and P 5 ppm were considered. Result indicated that the lowest values of germination percentage, shoot length, root length and dry weight of two test species were in treatment P 6 and highest in P 1 treatment. Thus, ten selected vegetables in Bangladesh could be used to control associated crops. Therefore, these vegetables used in this study could be candidates for isolation and identify of phytotoxins to serve as weed inhibiting agents for sustainable crop production.
