摘要

In order to study the effect of water deficit stress and different nitrogen levels on flower yield and yield components of Calendula officinalis L., an experiment was conducted as split plot design based onrandomized complete blocks with three replications, at research field of Islamic Azad University of Birjand branch in 2009. In this research water deficit stress set as main factor with three levels (irrigation after 60, 120 and 180 mm cumulative evaporation from pan class A) and nitrogen set as sub factor with four levels (0, 60,120 and 180 kg N. ha-1). The number of flowers per m2was 2.58 times greater in the treatment of irrigation after 120 mm accumulative evaporation than in the treatment of irrigation after 180 mm, but it showed an 11.2% loss compared with the treatment of irrigation after 60 mm accumulative evaporation. Also treatment of irrigation after 180 mm accumulative evaporation decrease of single flower weight by 13.3 and 18.2% at the treatments of irrigation after 120 and 60 mm accumulative evaporation, respectively. Means comparison showed that the increase in N fertilization rate from 0 to 180 kg N.ha-1significantly increased the number of flowers per m2, flower fresh and dry yield by 33.7, 36.8 and 35.4% respectively. Finally, the results indicated that treatment of irrigation after 120 mm evaporation with 120 kg N. ha-1application is suitable for marigold cultivation in Birjand
