Abstract EN

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.
