Abstract

A field experiment was conducted at the Agricultural Research Station, Sari,Mazandaran Uni. to evaluate the effect of tillage, row spacing and weeding on soyben production and weed management. The experiment was a split plot in a randomized compelet block design with four replications. The main plots were tillage at three levels; Conventional tillage (CT) Reduced tillage (RT) and NO-tillage (NT). The sub plbts were factorial of row spacing at three levels: 60-, 50-,and 40 cm at two levels of weeding; weed-free check and weedy check. Three tillage systems in weed free check had no significant difference in height of soybean but in weedy check the maximum height was obtained in conventional tillage. In disk and no-tillage systems, dry weight of soybean (12 weeks afrer emergence) compared with conventional tillage was decreased 15.5% and 8.5%, respectively. Weed-free check produced 55,47, and 46 pod/plant in CT, RT and NT, respectively while weedy check plot produce 25,29, and 35 plot/plant. Tillage plot yielded 36,39, and 46 pod/pInt in 40-50, and 60-, cm of row spacing while reduced and no - tillage system yielded 34 and 37, 39 and 40, and 41 and 43 pods/plant in 40-, 50-, and 60-, cm of row spacing, respectively.Soyben yield production was 3559 , 2647, and 2532 kg/ ha for CT, RT, and NT in weed-free check and 1223, 1339, and 2198 kg/ha in Weedy check, respectively. In terms of weed infestation, no-tillage system had 77% less weed and produced 61% less weeds dry weight compard to CT. NO - tillage system could be recommended as a weed management practice to reduce weed pressure.
