In order to study the effect of sowing dates and clipping times on the yield components and forage in dual cultivation of barley , a split plot experiment in the form of randomized complete block design with for replications was carried out in Golestan agricultural and natural resources research farm in 2012-2013 .Three sowing dates i.e. Now 5, Dec 5 and Jan 5 were in main plots, and sub plot were different clipping times {30 Beginning of stem elongation ; first internode begins to elongate (clipping time1), 33 Node 3 at least 2 cm above node 2 (clipping time 2), as well as control (no clipping)}. Condition represented the effect of sowing dates was significant on feed and grain yield, Protein yield, Plant height, HI. Maximum Plant height, HI and grain yield was recorded in sterling. The highest Feed yield, grain yield was observed in clipping time1. sowing dates at dec 5 resulted in maximum Plant height, Harvest Index, feed yield, grain yield, Protein yield.Condition represented the effect of sowing dates was significant on feed and grain yield, Protein yield, Plant height, Weight of 1000. Maximum Plant height and grain yield was recorded in sterling.
