investigating the effects of urea, azocompost and cutting on quantitative and qualitative characteristics of oregano (origanum vulgare virid)

in order to investigate the effect of urea, azocompost and cutting on growth characteristics of oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at yazd and mashhad, iran, during 2012-2013 growing season. four urea levels and four azocompost levels (to provide 0, 40, 80 and 120 kg n.ha-1 each) for yazd location )0, 43.5, 130.4 and 217.4 kg urea.ha-1 and 0, 4.4, 13.3 and 22.0 ton azocompost.ha-1) and for mashhad location (0, 21.7, 108.7 and 195.7 kg urea.ha-1 and 0, 2.2, 11.1 and 20 ton azocompost.ha-1) were considered as the main factors and harvesting time as the sub factor. in the present study, some growth traits, yield, yield components were measured. the results of combined analysis showed that two-way interaction between urea and azocompost was significant for all traits except for essential oil content (p
