Journal Article 2021 05 29 To evaluate the effect of planting date and different amounts of manure, chemical fertilizer and their combination on some agromorphological and essence characteristics of Moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of Shahrekord University in 2018. In this experiment, the main factor was 3 levels of planting date (20 April, 12 May and 3 June), while 6 levels of manure application (no fertilizer, control; 25% urea + 75% manure; 50% urea + 50% manure; 75% urea + 25% manure; 100% urea and 100% manure) were the subplot factors. The results showed that planting date and fertilizer and their interaction had a significant effect on all the studied characteristics, so that, the maximum number of flowering branches and biological yield were obtained from 3 June + 100% manure and 3 June + 50% urea + 50% manure, the maximum essential oil from 20 April and 3 June + 100% manure and the maximum essential oil yield from 3 June and 100%.
