Soil surface contains huge quantity of seeds of various weed species. Study of weed seed distribution in the soil allows prediction of seed occurrence, as well in which volume under various crops. In such a manner, it is possible to make more efficient and economic plan of measures for their control. In the period 2011-2012 on the territory of AP Vojvodina, seed bank of perennial vineyard plantations in vineyard region of Suboticko-Horgoška Pešcara was studied. In the period 2009-2010, the identical studies were carried out at locality Despotovo in the annual maize field culture. The sampling was performed diagonally in ten replications and with several depths of the arable soil layer, i.e. 0-10, 10-20 and 20-30 cm. The highest number of weed seeds was found in perennial vine grape plantation at depth of 10-20 cm at locality Subotica (118503 seeds per m2), followed by depth of 0-10 cm, (14914 seeds per m2), lowest number of weed seeds was recorded in the soil layer of 20-30 cm, (13239 seeds per m2). In maize crop, the highest number of weed seeds was found at locality Despotovo, in the soil depth of 20-30 cm, (4498 seeds per m2), followed by soil depths of 10-20 cm - 3604, and of 20-30 cm -1431 seeds per m2.
