The Effect of Seed Size and Nitrogen on Root and Shoots in the First Development Stage of Barley

This research was conducted to determine the effects of seed size and nitrogen fertilization on seedling growth of barley cultivars Angora and Cumhuriyet-50 at Çanakkale Onsekiz Mart University, Faculty of Agriculture in 1997. According to results of the research, there were significiant differences between Angora and Cumhuriyet-50 cultivars for seedling length (in field research), leaf number, dry weight of above-soil surface organs, and root/dry weight ratio of above-soil surface organs. Seed size significiantly affected seedling length (in pot research), leaf number (in pot research), dry weight of above soil surface organs and root-dry weight, and large seeds produced heavier seedlings. It was determined that nitrogen fertilization significiantly affected seedling height, dry weight of above-soil surface organs (in field research), root-dry weight, and root/dry weight ratio of above-soil surface organs (in pot research). It was also determined that the difference between large and small seeds for seedling weight may be compensated for by nitrogen fertilization.
