چکیده
In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilizer (NPK) (15-5-30) and Marmarin fertilizer and the levels of secondfactor were involved two types of media (100 percent peat and 60 percent animal manure with 40 percent perlite media). During the experiment the concentration of nitrogen and ammonium levels were sampled and analyzed in nutrient solution after 10 days. The most of the nitrate andammonium ( 48.82 and 63.8 ppm ) were obtained from chemical fertilizer in the peat media at the first sampling whereas the lowest nitrate and ammonium (4.02 and 5.57 ppm ) was belonged to chemical fertilizer at peat media and chemical fertilizer at perlite media with manure treatments, respectively, which was recorded at fourth stage of sampling.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
