The Effect of Cutting Time under Different Amounts of Nitrogen on Yield and Yield Components of Barley

Abstract

The present research was aimed to study the effect of different levels of inorganic fertilizer N on the yield and yield components of barley varieties at Gorgan Research Station Iran in 2014-2015 year A split plot layout within randomized complete block design with 3 replications was used Main plot were different level of nitrogen fertilizer 35 70 and 105 kg N ha-1 from urea source and sub plot were different varieties Line 3 Line 7 and Line 17 Condition represented the effect of nitrogen 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 Line 5 variety Nitrogen applied at the rate of 105 kg N ha-1 resulted in maximum Plant height Harvest Index feed yield grain yield Protein yield
