| Popis: | Although micronutrients effect on growth and yield of different plants has been intensively investigated, but there is limited information on its effect on grain yield and seed oil content of pot marigold) Calendula officinalis L.). In order to investigate the effects of micronutrients (Fe, Zn and Mn) spraying on yield and yield components and seed oil of pot marigold, a field experiment was conducted based on randomized complete block design with three replications at the Research Farm of Payame Noor University of Nagadeh in 2010. Treatments included Fe, Zn, Mn, mixed solutions of these elements (Fe+Zn, Fe+Mn, Zn+Mn, Fe+Zn+Mn) and control (water). Treatments were applied in 2 g/litter twice at stem elongation and early flowering stages. Different traits such as plant height, number of capitol per plant, number seed per capitol, thousand seed weight, biological yield, seed yield, seed oil percentage and oil Yield were recorded. The results showed that foliar application of micronutrients had significant effects on all of these traits. Yield components, seed yield, oil percentage and yield were enhanced by foliar application, compared with control (untreated plants). The maximum number seed per capitol, thousand seed weight and biological yield were relevant to Fe treatment. The highest numbers of capitol per plant and seed yield (643.33 kg.ha-1) were relevant to Zn+Fe treatment and the maximum oil yield (124.20 kg.ha-1) was produced by Zn+ Fe+ Mn treatment. Seed yield and oil yield increased by 31.27% and 44.18% yields more than control, respectively. It can be concluded that, foliar application of micronutrients had positive effects to obtain high yield and oil of pot marigold. |
