Effect of Planting Date and different amounts of manure, chemical fertilizer and their combination on some agromorphological and essence characteristics of Moldavian Balm

In order 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 dates: 20 April, 12 May and 3 June, while 6 levels of manure application: 1) no amended fertilizer (Control) 2) 25% urea + 75% manure 3) 50% urea + 50% manure 4) 75% urea + 25% manure 5) 100% urea and 6) 100% manure, were used as subplot factors. The results showed that planting date, fertilizer and the interaction of planting date and fertilizer had a significant effect on all the characteristics studied at this experiment. So that, the maximum number of flowering branches and biological yield were derived 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 planting date of 3 June and 100% manure were obtained.
