A replicated field experiment was conducted in BCKV university instructional farm to quantify the weed management effect on vertical distribution of weedseed bank in aerobic crop ecosystem in the year 2012-13 and 2013-14. The experiment was framed with five weed management treatments in boro and kharif season. The number of total wed seed bank was highly influenced by weed management treatments. With the beginning of the experiment, around 141.05 numbers of weed seed were present in 0-10 cm soil depth and 56.40 numbers of weed seed in 10-20 cm soil depth. At the end of the experiment, the number of weed seeds was maximum in the control plots as compare to the initial count. The hand weeding treatments recorded minimum numbers of weed seeds of 61.00 and 22.50 in 0 – 10 and 10 – 20 cm soil depth. And the weed seed bank was enriched in boro season as compared to the kharif season.
