Effect of organic fertilizers on nutrient and transferable transplanting Percent of tobacco in nursery media

ABSTRACT: This study was performed to production of tobacco transplanting by using of organic fertilizers. Experiment was conducted in Tobacco Research Station of Urmia in a plastic tunnel across 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 second factor 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 phosphate, potassium and pH levels were sampled and analyzed in nutrient solution after 10 days. Maximum value of phosphorus (58.39 ppm) was obtained from poultry manure in the perlite media with manure at first sample and the lowest (2.73 ppm) was belonged to pigeon manure at peat media in the second stage of sampling. In the first stage sampling, most of potassium was (409.67 ppm) obtained from chemical fertilizer in the perlite media with manure and lowest (10.78 ppm) one is belonging to Marmarin fertilizer treatments in peat media at the second stage of sampling. The effect planting media and interaction effect of fertilizer × planting media were significant transplanting transfer percentage of barrel 21 and the maximum transferable transplanting Percent (76.81) was belonged to chemical fertilizer treatment at peat media, while itʹs minimal (10.22) was obtained from poultry manure treatment in the perlite media with manure.
