Abstract
A Field experiment was carried out in one of the farmers field in AL-Soraa area in the east of Ramadi city , AL- Anbar during the winter season (2012-2013 ). To study the effects of row spacing, number of cutting on Green forage yield , dry yield and some quality characteristics of Green forage yield for three cultivars of barley. The achievement of the experiment , a split-split-plot in Randomized complete block design (R.C.B.D) with three replications was used . The rows spacing (10,15) cm between the rows were taken as main plots , while cultivars (Samir, bohuth 244, bohuth265) were taken as the sub-plots . and clipping (cut once, cut twice and three time) were taken as the sub-sub plots . The important results were as the following. Row spacing 10cm was superior significantly in green forage yield , dry matter , fibers percentage (18.87 ton , 5.39 ton , 24.99%) respectively. Smire cultivar was superior significantly in plant height 1cm green forage yield dry forage yield . protein percentage yield (61.62 cm, 20.21 ton , 5.746 ton, 15.317%) respectively. Result show that interaction between cultivar samire and the treatment three time cutting give asignificant increasing in all studding characteristics without protein percentage , green forage yield .There was significant interaction between 10 cm row spacing and three time cutting in green forage yield , dry matter yield , crude protein percentage , crude fiber percentage . And their values were (29.15% , 30.24 ton/ha , 8.860 ton/ha , 15.944% , 25.27% ) respectively . There was a significant interaction between 10 cm row spacing for samire cultivar with three time cutting on green forage yield , dry forage yield and its give (35.05 ton/ha , 10.39 ton/ha ) respectively
