Effect of Sowing Dates and Population on Yield and Yield Components and Forage in Dual Purpose Cultivation of Hulless Barley (Hordeum vulgare L.)

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.
