The research was carried out during (2008-2009) and (2009-2010) in Fedio farm belonging to the Faculty of Agriculture to study the effect of various systems of tillage on the growth and productivity of Barley.
The results showed that the bulk densit
y increases with the first tillage system (control), comparing with the other tillage systems, but all of them were less than the control (no- tillage). The number of weeds increased when using the 6-th tillage system. The germination rate was affected by the tillage systems. The 6-th tillage system was the best. The weight of 1000 seeds and productivity increased by the 1-th tillage system (no-tillage) comparing with the other tillage systems. The number of weeds increased, but germination rate and weight of 1000 seeds decreased by using the 6-th tillage system. The yield of barley increased when using the 6-th tillage system. No-tillage system was the most economic compared with the others.
