| Abstract | ||
| A field experiment was conducted drying growing season 2010-2011 at Talkief and Hamdania locations in Naniva provancy to study the effect of tillage systems (no till , conventional till ) and seeding rates (80 , 100 , 120 kg/ha) on weed growth and barley productivity var .Reehan . However , the locations was the third factors . The result showed that the number dry weight .of grass weeds were reduced up to 42% in no till if it compered with con. till but there were no significant ( No.Dwt) between the two systems with broadleave weeds .Yield of Barley was increased in no till when it compared with con.till . On other hand , there were reduction in number or dry weight of grass and broadleaves weeds at increasing seed rates which reflected on high yield production . In general , grass weeds (No.Dwt) and Dwt of broad leav weeds had reduction in no till at seed rate 100 kg/ha at Talkie which it rised the barley yield at every seed rate, while superiority of yield was seen at 120 kg/ha seed rate at Hamdania . | ||
